How to Fix a Leaking Boiler

Diagnosing boiler leaks can be a difficult task. It needs a strategic approach and a close look at the boiler from top to bottom. In most cases, boiler leaks are not serious and can be repaired rather easily. But, left unattended, they can affect the performance of the boiler and cause significant damage.

Before you call in the experts, you can attempt to diagnose the boiler yourself if you have some experience. Sometimes, boiler leaks are easy to fix and you can save yourself a hefty repair bill. But, fixing a leak can also be dangerous. If you haven’t worked on a boiler before or you feel uncertain, it might be best to get help.

Common Causes for Boiler Leaks

Faulty pressure valve

If the boiler is leaking from the boiler pressure valve, the pressure of the boiler may be too high. Ideally, the boiler should function at between 18 to 21PSI. The pressure valve is designed to leak if the pressure is too high as safety protection. This helps to prevent other appliances from getting damaged.

All you need to do to determine if this is the problem is to check the needle on your pressure gauge. If it’s out of the green section and in the red, there’s too much pressure in the boiler. It’s also possible that sediments and limescale are trapped inside, which could also cause the valve to leak.

How to fix a leaking pressure valve:

The fix depends on what’s causing the valve to fail. Here’s a quick guide that can help you get to the bottom of things and get your boiler back on its feet.

  • Turn off the boiler and give it time to cool off.
  • Once it has cooled down, let some of the water out by lifting the manual pressure relief level for about 3 seconds. The water will come gushing out and should be clean. If the leak continues after letting out some of the water, there may be sediment trapped inside.
  • Repeat the process to see if the leak stops.
  • If that doesn’t help, close the water feed to the boiler, then remove and replace the relief valve.
  • Water should come out of the pressure relief valve. If water doesn’t come out, the valve may be plugged. It might need to be replaced.

While you’re in there, you might also want to check the boiler expansion tank. Sometimes, a problematic pressure valve could also indicate the boiler expansion tank is filled with water. You might need to address this problem as well.

Faulty temperature valves

The leak could also be as a result of a defective temperature valve. If the boiler pressure goes too high, it could trigger a leak. If the temperature valve is faulty, there are no two ways about it. The only way to fix is to replace it. Once it’s repaired, the leak should stop.

Corrosion in the Boiler

For older boilers, one of the most common causes of leaks is corrosion. Corrosion not only affects the boiler but also the pipes and tanks. It causes them to be weak over time and eventually pokes holes causing leaks. The fix depends on the location of the corrosion. If it’s around a valve, replacing the valve could get rid of the problem. If it’s more extensive, you might need to replace the boiler.

Poorly installed pipe fittings

Ill-fitting pipes can be another weak spot for your boiler, and they leak quite easily. If the leaks are happening after recent repairs, it’s worth checking the pipes to see if they fit correctly. If that’s the cause, you need to have the pipes reinstalled and that should take care of the leaks. When the leak has been going for an extended period, the damage to the boiler might be too severe and you might need to change the boiler and pipes.

Faulty seals or pumps

Seals on your boiler pump can come loose. If they do, the boiler can start leaking. Luckily, this is an easy issue to fix. Replacing or resealing the pump will stop the leak. Some boiler problems, including most leaks, are relatively easy to fix. You don’t need an engineer to come over for assistance. With these simple boiler leak fixes, you can get your boiler working again in no time.

However, if you don’t have experience handling boilers, even if the fix is simple, it’s vital to have an engineer give it a look. Boilers can be dangerous, especially in inexperienced hands.

How Does a Boiler Work?

Boilers are a staple in most homes in the UK. For most people, all you have to do to get your boiler to work is to flick a switch. But, there’s more to the functions of a boiler than just the switch. Understanding how your boiler works can help you make better use of it and enjoy longer service. It will also make it easier for you to understand what’s wrong with your boiler when it breaks down and how you can approach the situation.

Construction of Central Heating Gas Boilers

The principle on which boilers work to keep the home warm is quite simple. The boiler transfers heat to the water. The water is then pumped around the house through a series of pipes. However, this is only the basic principle behind the functioning of a boiler. There are a variety of parts and engineering required to achieve it. That’s what it’s vital to start with the construction of the boiler.

Gas boiler design and function is very similar to other types of heating. In gas boilers, a highly flammable gas along with additional safety features are included to get the boiler to work safely.

The main components inside the central heating gas boiler include:

  • A gas burner – This component is tasked with generating the heat that is transferred to the water
  • Heat exchanger – It transfers the heat between a solid object like the gas burner and the fluid
  • Control technology – This unit controls the functions of the entire heating system
  • Diaphragm expansion vessel – These are pressurised water vessels. They allow the water to expand and absorb the pressure which increases as the water is heated
  • Exhaust pipe – The burning action results in poisonous gases like carbon monoxide. To prevent these gases from causing harm, an exhaust pipe is added to safely remove the gas from inside the house

How a Gas Boiler Creates Heat

The central heating element in the gas boiler is the burner. You switch it on and off using the heating control unit. The switch is triggered manually or through a thermostat that reacts when the temperature drops below the set levels. Even with the thermostat, the heating control remains the most critical component of the heating assembly. It allows for smooth and easy operation of the system. The unit also facilitates communication between the outdoor and indoor temperatures sensors.

For safe ignition, a Piezo ignition ignites for about two seconds before the gas line opens to let out the gas. The delayed opening prevents a build-up of unburnt gases which can explode upon ignition. The burner is connected to the heat exchanger that heats the water. Once the water is hot enough, it is pumped to the heating circuit.

How Other Types of Boilers Work

Gas boilers are extremely popular. But there are other varieties like electric boilers and oil boilers. If you happen to have one of these, it’s also crucial to know how they function and what makes them unique or similar to the gas boiler.

Oil boilers

Oil and gas boilers are quite similar. For the oil boilers, instead of gas, oil is the preferred fuel which is converted into heat in the combustions chamber. The process of heat transfer is the same. The burner is attached to the heat exchanger which heats the water which is then pumped to the around the house and to the storage tank for a system that also needs to provide hot water.

While the two systems are largely similar, they also have a few differences. The most significant is how the fuel is managed. Oil boilers need to have a storage tank where the fuel is stored. The oil is often delivered by a tanker and stored until it’s depleted. Oil boilers are eco-friendlier than gas boilers, but they are not as common. In fact, they are more common in the countryside where there’s no gas pipeline present.

Electric boiler

Electric boilers are an alternative in areas where there is no gas line. Electric boilers function a little differently because they don’t use solid fuel. They transfer energy to a heating element that heats the water. They are extremely friendly to the environment and in most cases, require fewer parts to get the job done. The downside of electric boilers is that they are not as efficient as the former types of boilers and are more expensive to run.

Boilers are complex pieces of engineering.  Their functioning is not. They employ simple principles that allow them to provide you with a nice and toasty home. Most of the features added to the boiler are for safety and to guarantee that if the boiler fails, it doesn’t cause harm to you or other occupants in the house.

The History of Nottingham Castle

Nottingham Castle is one of the most iconic monuments in Nottingham. It packs centuries of history and thousands of people come to see it. It makes for an interesting history lesson and there’s a lot that it has gone through, but thankfully, it has stood the test of time.

History

The castle was built by William the Conqueror in 1067 in a site of Promontory known as ‘Castle Rock.’ Since its beginning, the castle has grown to become one of the most important medieval landmarks in England. Even though William the Conqueror receives most of the credit for building the castle after the Norman conquest of England, it’s not certain if the castle existed before these events.

But the first castle, which was the Norman Castle, was undoubtedly a wooden structure built in 1067 after the battle of Hastings took place. It was replaced by a more efficient and more formidable stronghold made out of reconditioned stone during the time of King Henry II. The upgrade cost the royal treasure £1,737 which was a monstrous amount at the time.

The Royal Coup

Not only known for its majestic appearance, but the castle also was never short of drama. The year 1330 was a special one in that aspect. In 1326, Edward II had been deposed by his wife and her lover. In 1327, Edward died under suspicious circumstances at the Berkeley Castle and his wife Isabella and her lover Roger Mortimer acted as regent because the prince was still a minor.

When Prince Edward turned 16 in 1330, he and a few of his trusted allies aided by a conspirator called Eland sneaked into the Nottingham Castle through a tunnel whose door was left open by Eland.

The prince seized Mortimer and took him away through the same tunnel before the guards could respond. He sent Mortimer to the Tower of London where he was tried and executed for treason. Isabella didn’t suffer the same fate but was forced into exile. In 1460, Edward of York was declared as King in the Nottingham Castle. He later took the throne as Edward IV. He was then succeeded by his brother Richard the III who had a short reign.

Robin Hood

The Robin Hood folklore and the castle are joined at the hip. The two have loads of history together and today, there’s a statue and the Robin Hood Lawn as a result of this history.

Legend has it that Robin was once captured by the wicked Sheriff and held a prisoner in the caster. He escaped through the caves into the Sherwood Forest where he took refuge. The Castle was the Sheriff’s stronghold and it appears as the setting for several of Robin Hood’s stories as well as several encounters between him and the Sheriff.

Art Gallery

Today, Nottingham Castle has a rich collection of art that was founded in 1878. The collection includes prints, watercolours, pottery, drawings, jewellery, oil paintings, silverware, and glass. There are close to one hundred paintings on display at the gallery and there’s also a collection of medieval alabaster sculptures.

Cave Tours

Nottingham Castle has plenty for you to see. Other than the museum and the art gallery, guided tours are also available to visitors. You can visit the caves that permeate Castle rock and even get to see the foundation walls of the castle on the lawn outside the museum. There are magnificent views from the top of the castle mound, but as a safety tip, make sure you have suitable footwear when going here.

Unfortunately, the cave tours and the Museum of Nottingham are currently under renovation. As a result, the areas will be closed to the public until 2020.

10 Facts About Nottingham You Won’t Believe!

Nottingham never ceases to amaze. From the stunning Robin Hood folklore stories to the exponential history, Nottingham is the perfect place for conspiracy theorists or just the average person snooping around for some juicy facts.

If you’re a resident of Nottingham or looking to move there, here are few interesting facts about the city that are not only captivating but will likely get your curiosity antennas alert.

  1. Nottingham has the Smallest Cinema in the world

Are you a fan of the big screen? The experience you get at Screen 22, which is the world’s smallest cinema is unlike anything you have seen before. The cinema is the creation of Steven Metcalf and was started in 2002. The cinema has a seating capacity of 21 people.

Steven, a movie enthusiast, started the cinema to allow people that missed the first screenings of their favourite movies a second chance to see them. It’s more interesting that the small cinema is located only six minutes away by foot from Cineworld, which is currently regarded as one of the most independent cinemas in the country.

If you’re looking for a cosy place to catch up on the latest movies with your friends, this little cinema could be just the place.

  1. Nottingham was once called Snotingham

Residents of Nottingham must be ecstatic with the name change. Believe it or not, Nottingham has not always had this name. Back in 600 A.D, the city was known as Snotingham after an Anglo-Saxon chief called “Snot.”

Loosely translated, the name meant the town of snot people. It’s quite a relief that the name of the city hasn’t stuck.

  1. The Goose Fair

The Goose Fair is not a new or astonishing fact. What might be astonishing is the fact that it has existed since 1284. It was once known for its high-quality cheese. Today, it’s one of the most prestigious fairs in the UK with over 500 attractions, rides, and games.

The Nottingham Goose Fair is held at the Forest Recreation Ground and has been for many years. The Goose Fair is more than 700 years old and qualifies as one of the oldest fairs in the world.

  1. Ibuprofen was invented in Nottingham

Nottingham is also the home for quite some exciting inventions, one of them being Ibuprofen. The famous drug was invented in 1953 by Boots Pharmacist Dr. Stewart Adams while working in a house south of Nottingham. The doctor was performing clinical trials on pain-killing chemicals and Ibuprofen was the only success he had in the trials. He went ahead and tested it on himself for a hangover.

Since then, Ibuprofen has risen to become one of the most popular over the counter painkillers in the market today.

  1. Traffic Lights were invented in Nottingham

Traffic lights save countless lives each day. With the growing number of cars and road users, it’s impossible to think of what the roads would be like without traffic lights.

What’s even more surprising is that this valuable invention has its roots in Nottingham. After seeing thousands of road users die, John Peake Knight, a student from Nottingham High School, came up with an idea. In 1866, he created a system that used a revolving gas-powered lantern that had a red and green light to help control traffic.

The very first traffic light was placed at the Great George Street and Bridge Street junction in Westminster London. Today, traffic lights are a standard feature on the roads everywhere in the world.

  1. Little John could one day replace Big Ben

Little John pales in comparison to the mighty Big Ben. But, the iconic bell packs a variety of interesting facts that might blow your mind away.

Little John is not so little. The gigantic bell which goes off every 15 minutes is the loudest clock bell in the country. Its strike can be heard up to 7 miles. Even more stunning is its 10.5-tonne weight.

In 2015, the Nottingham City Council offered to loan Little John to replace Big Ben if the iconic bell ever fell silent.

Little John doesn’t sound so little now, does he?

  1. Nottingham is the home to Robin Hood

The history between Nottingham and Robin Hood is not a secret. It’s not even surprising but, not mentioning it would be a surprise.

The heroic outlaw from popular English folktales was a highly skilled archer and swordsman. His affection for the poor and disadvantaged pushed him to steal from the rich and give to the poor. He had his team of outlaws called the “Merry Men.”

Did you know that the gigantic oak which served as the hideout for Robin Hood and his Merry Men still stands tall today? It’s located in Sherwood Forest and weighs a staggering 23 tonnes with a girth of over 10 meters and a spread of 28 meters. It also happens to be the biggest oak tree in Britain.

  1. Wollaton Hall was Batman’s Layer

Fans of the 2012 Batman Dark Knight Rises that have visited the Wollaton Hall, and are keen enough, might have noticed some familiar scenes. That’s because the Wollaton Hall was used as the setting for Wayne Manor in the film.

Since then, the site has attracted more visitors each year in what is known as the Batman Effect as well as improved marketing. In 2014, there were over 290,000 visitors to the Elizabethan Mansion.

  1. The Nottingham Sheriff Exists

The Robin Hood story might be folklore but, the sheriff of Nottingham, who was his arch-nemesis was not. The Sheriff of Nottingham is an actual position that exists to date. The sheriff is responsible for welcoming visitors and promoting the historical associations in Nottingham. The role is not as flashy as it is in the stories, but it creates some realism to the greatest legend in Nottingham.

  1. Nottingham is home to the HP source

The popular HP sauce is yet another product of Nottingham. It was invented by Frederick Gibson Garton while in his packing factory in 47 Sandon Street Nottingham.

The sauce was named HP sauce in 1895 after the inventor learned that the Houses of Parliament were serving his source. This makes Frederick one of the many fine inventors that are born and bred in Nottingham.

Conclusion

Nottingham never ceases to amaze. It’s a great and vibrant city that provides the perfect environment for virtually every personality. It’s packed with history, beauty and as you can tell from these facts, surprises. It makes for the perfect place to live and work for families, bachelors, and bachelorettes.

How Often Should a Boiler be Replaced?

As professional boiler installers in Nottinghamshire, we get asked this question a lot. Boilers are the pride and joy of every home, especially during chilly Seasons. It’s imperative to make sure the boiler is in proper working condition to keep up with its demanding job. If you’ve had the boiler for some years, you must be wondering when you should have it replaced.

There are no set rules when it comes to how often the boiler needs to be replaced. The boiler can last for as long as 15 years or more if it’s a good quality boiler and have done an excellent job of keeping it in good shape.

The type of boiler and the service schedule are just some of the factors that will determine how long your boiler last. But, you should keep out an eye on the tell-tale signs of when your boiler needs to be replaced.

Does my boiler need replacing?

You don’t have to wait for your boiler to completely break down to replace. Before meeting its doom, there are signs the boiler will have indicating that its life is coming to an end. Identifying such signs will save you money in unnecessary repairs and the inconvenience of frequent cold showers.

Some of the signs that you need to replace your boiler include:

Your home is now the boiler engineer’s home

As your boiler grows older, it fails and breaks down more often. You will have constant visits from the boiler engineer as he tries to revive the boiler only for it to break down again after a few uses.

Compared to the cost of buying a new boiler, keeping on plugging holes in the old boiler is tempting and deceptively cheap.

But, if the boiler is more than 10 years old, you’re only postponing the inevitable and digging yourself deeper into financial misery. The repairs will only get more expensive not to mention you might be paying more for your energy bill.

If your boiler is losing pressure, read our latest blog post: What to do if your boiler is losing pressure.

Your heating bills are through the roof

Gas bills will steadily creep up as the boiler grows older and loses efficiency. You will save more on your energy bill by cutting ties with the old system and investing in a new one.

An inefficient boiler will use more energy and waste more heat. Energy consumption will only increase over the years and the efficiency will drop as low as 50%.

To protect yourself from bleeding money, consider buying a new boiler for your home. You’ll be happy you made the decision down the line.

The boiler has become smelly

As the boiler grows old, you will notice an unusual smell coming from the boiler. It’s not only a bad sign but one that could turn catastrophic.

The smell is a result of gas leaking and should be reported immediately to avert the risk of an explosion.

There’s also the risk of carbon monoxide poisoning. Unfortunately, because the gas is odourless, you will only notice the effects. You can install a detector close to the boiler to monitor carbon monoxide. If the sensor goes off, you should evacuate your home immediately and call the emergency number.

Unusual noises in the boiler

As the boiler grudgingly comes to the end of its life, it’s going to be cranky with lots of knocking, popping and hissing sounds.

Different components of the boiler will have a hard time working and keeping up with the demand around the house. The task at hand will no longer be as easy as it once was.

You can call the engineer to give the system a check and make sure everything is working properly. However, if this happens often, and the repair bill keeps going up with more expensive parts requiring replacement, you should consider having the system replaced.

Yellow flame

The flame that was once blue is now yellow! It could be caused by an overdue service but, you should call in a Gas Safe engineer who will tell you how serious the problem is and how best to solve it. For old boilers, more often than not, replacing the boiler will be easier.

It’s hard to get replacement parts

Boiler technology advances very fast. New parts and components with better technology and performances are regularly released and added into the new boiler. The ripple effect is that older parts become harder to find as the older boilers become obsolete.

If you have to wait a few days or weeks for the engineer to source for a replacement part, it’s probably best to embrace technology and go for a new boiler with readily available parts.

The boiler is out of touch with smart technology

Today, boilers can do all kinds of things thanks to technology. You can go as far as firing up your boiler when you leave work, so you find your home nice and toasty when you walk through the door.

Most homeowners will not dispose of their boiler just because it doesn’t keep up with modern trends but, those trends also come with additional benefits like convenience, better energy efficiency and ultimately, more savings for you.

If you notice any of these signs, it’s about time you had that boiler replaced. When selecting the new boiler, make sure you consider all the relevant factors, including how future-ready the boiler you’re picking is. This will allow you to delay the next boiler replacement and make the most out of your new boiler acquisition.

Boiler is Losing pressure. What To Do?

As the leading Boiler Installation Company covering Nottingham, we are used to seeing a variety of issues with boilers. A substantial number of problems that your boiler faces are usually rooted in boiler pressure. Boiler pressure is such an essential part of boiler functions. If it goes too low, the boiler will cut out to prevent damage.

Even though the problem sounds dire, the good news is low boiler pressure is easy to diagnose and, in most cases, it’s also easy to fix without the assistance of a Gas Safe engineer. In this guide, you get to learn about the most common boiler pressure problems and the possible fixes that you can try out before calling out an expert.

What is Boiler Pressure?

A boiler heats cold water that flows around a circuit of pipes and radiators around the house. For the process to be efficient, the pressure needs to be stable. In most modern boilers, there’s a filling loop which is used to maintain the pressure.

The loop connects to the cold water pipe and when the pressure drops, you can use it to increase pressure and restore the normal functioning of the boiler.

What causes boiler pressure to drop?

There are various culprits in low boiler pressure. But, there are two that stand out:

Leaks

If your central heating has a leak, the water lost through the leak causes the boiler pressure to drop. Unfortunately, leaks can go unnoticed for some time and the gradual drop in pressure masks them very well.

If you notice you have to top up the boiler pressure more often, it could be caused by a leak. Try looking for damp patches around pipes, radiators, and the boiler. But, don’t look for the leaks inside the boiler. That’s a job best left for the professionals.

If you find the leak, you should call a Gas Safe registered engineer who will fix the problem. In some cases, leaks are not only the result of a worn-out pipe. They can also be caused by failing valves or worn out seals.

Bleeding radiators

If you’ve heard to bleed your radiators recently, you might have lost some pressure. When you bleed the radiators, the air is released. It lowers the pressure inside the boiler system which might cause a broad range of problems.

Read our latest blog: Boiler Doesn’t Respond to Thermostat…What to do.

How can I check the pressure on my boiler?

If this strange problem is happening to you for the first time and you’re not sure where to start, it’s best to start by checking if the pressure of your boiler is right.

The process of checking the pressure will depend on the type of pressure gauge you have. If it’s a hydraulic gauge, you will see the low and high-pressure levels by red sections on the dial.

If you have a digital gauge, you see a flashing pressure reading. You will also be notified if the pressure reading is too high or too low.

Pressure readings below 1 bar are considered dangerously low. If the pressure falls below 0.5bar, most boilers won’t work.

The ideal pressure setting for your boiler is between 1.5 to 2 bars. If the pressure goes above 2.75 bar, you need to bleed the radiators down to 1.5bar.

Can I Fix low boiler pressure myself?

Most low boiler pressure systems are easy to manage and you can easily fix them without the help of an expert. However, this is only advisable if you know your way around the boiler. If it’s your first time, call in an expert who can walk you through the steps before attempting it yourself.

How to re-pressurise the boiler

The first step to repressurising the boiler is to check the user manual and make sure it’s safe to proceed.

You need to find the filling loop on your boiler. It differs depending on the age and design of the boiler. Some have an actual filling loop while other boilers use a filling key and a manifold nut. Once you locate the appropriate filling system, you can follow the steps below carefully.

  • Switch off the boiler and allow it cool down completely
  • Check the ends of the filling loop and make sure they are securely attached
  • Open both valves to allow water from the cold mains into the boiler. You can hear the water flowing into the system
  • As the water flows into the system, check the pressure gauge so you don’t overfill the system. It should go up to 1.5 bar.
  • After you attain the optimum pressure for the boiler, you can close both valves one after the other.
  • Double-check to make sure you have the right pressure then proceed to switch the boiler back on.
  • In some cases, you might need to press the reset button to clear the error
  • After the boiler fires up correctly, undo both ends of the filling loop. Take precaution to catch any water spillage and keep the filling loop safely. You will need it again.

Even though it sounds serious, you can easily re-pressurise your boiler at home. However, if you’re unsure of anything, it’s best to have an expert deal with the problem while you learn so you can do it yourself the next time.

If you notice a leak, have it fixed as soon as possible. That will protect the boiler from further damage and also curb the cost of having the leak fixed.

Boiler Does Not Respond to Thermostat. What Should I Do?

Modern boilers rely on a variety of components to function properly. One of those components is the thermostat. There should be two thermostats – one for the house and one for the boiler. All the three components should work harmoniously to make sure you get hot water and heat when you need it.

If there’s a breakdown in communication whether it’s from the boiler or the thermostat, the boiler will get confused and won’t know when to produce hot water and when to stop. If you find yourself in a similar situation, this quick read can help!

Types of Thermostats

Before you go foraging for the contact of your boiler installer, there are a few things you can try out that might save you the trouble of having to wait for an engineer. Before identifying the problem, you need to know what kind of thermostat your system is on. It will make it easier to narrow down the problems.

Electrochemical Thermostats

These are fitted on older and more basic models. They have a very simple mechanical principle that works on the basis of a strip of two different metals joined together. At times, the strips are in the shape of a coil.

The coils or strips expand and contract as the temperature fluctuates activating the contacts on either end of the thermostat. The mechanism is connected to a mercury switch which is responsible for opening and closing the point of contact.

Electronic Thermostats

These are more advanced varieties fitted in modern boilers. They are programmable, versatile and flexible. They have wireless options that you can connect to the boiler through a Wi-Fi connection and control the boiler remotely.

You can set the adjustments of the electronic thermostat to your preferred settings which is why they are often preferred. With the additional hardware and software, these types of thermostats are more sophisticated and also cost more.

Room temperature and setting don’t match

One of the most common faults with a thermostat is having the room temperature and settings not matching. This can cause the boiler to delay when starting up or fail to start running when it should.

It’s slightly hard to tell if your thermostat is failing but, there’s a neat trick you can use. Tape a small thermometer next to the thermostat. To get the most accurate reading, place a paper towel behind the thermometer.

Wait for about 15 minutes then check the reading of the thermometer and that of the thermostat. If the readings differ by more than a degree, there’s a fair chance the thermostat is not correct. You might have to recalibrate the thermostat or replace it.

Check settings on the thermostat

If you have recently changed the thermostat, it could just be a matter of the settings not being right. There are a few things you can check that could be causing the boiler not to respond to the thermostat.

Start by checking if the thermostat is set to heat and is calling for heat. You can tell this by the ‘Heat On’, flame icon or a shimmering sun icon displayed on the panel. The thermostat should call for heat as soon as the temperature falls below the heat setpoint.

Once you’re certain the thermostat is doing its job right, check to see if the boiler is switched on and the circuit breakers are on. Lastly, check to make sure that the wires are matched correctly and connected securely to the thermostat.

If the reason for changing the thermostat was the boiler not responding, it could be the boiler at fault. Call in an engineer to have the system diagnosed.

Other factors to consider

If you’re still having problems and the boiler still refuses to respond to the thermostat here are a few other factors you can look into when diagnosing the thermostat:

  • Check to see if the inside of the thermostat is clean
  • Make sure the thermostat box is level. If the box is not level, it can affect the accuracy of the internal components
  • Make sure the box is not placed under direct sunlight or in front of drafty windows. Poor positioning can affect the readings and accuracy of the thermostat.
  • Check if the anticipator is properly set. For mechanical thermostats, check for a little metal tab usually mounted on the round dial inside the thermostat. You can try pushing the tab gently to either direction to see if that solves the problem. If you’re not sure if it’s set correctly, you can compare with the owner’s manual.

Some thermostat problems are easy to deal with, however, if you’re not sure of what the problem could be, it’s best to have a professional boiler installer or engineer come and assess the system and recommend the best solution.

How Much to Move a Boiler?

The need to move a boiler might arise when you’re moving to a new location. You might be interested in knowing the cost of moving the boiler versus buying a new boiler and having it installed at the new location.

Unfortunately, there’s no base price on the cost of moving the boiler to a new location. It can cost you as little as £150 and over £500 depending on a variety of factors. These factors include:

The Location

Your current location is the first factor that will determine how much you pay to have your boiler moved. Base prices change depending on your location. Different engineers will charge differently depending on your location. In some cases, it might even be cheaper to have an engineer from the location you intend to have the boiler delivered come pick up the boiler.

The Distance

Distance affects the logistics of moving the boiler. The longer the distance the higher the price. Longer distances require more time and more sophisticated materials to be used. That will always translate to a higher price.

If you’re just moving the boiler a few feet, the cost will dramatically decrease. Sometimes, all you want is to move the boiler:

  • Upstairs
  • Downstairs
  • Into a garage
  • Another room
  • Into the loft

Installation Work Required

Some installation work is needed at the new boiler location. If you’re moving the boiler to a new house with all the pipework already in place, it’s going to be much cheaper for you.

But, if additional pipework, flues, extensions, and boiler fittings are needed, then you have no choice but to factor in the cost of the additional work in the total cost of moving the boiler.

Why move a boiler?

It’s a good question. The reason for moving the boiler differs from one person to the next. But, there are a few that are usually recurrent. Boilers are not always installed in the most convenient places. To create more space or better use of the house, homeowners can decide to move the boiler. This can help improve comfort and the appeal of the house.

You can also relocate the boiler to get better hot water response. Placing the boiler in a different area could give less pressure on it when delivering hot water.

Things to consider before moving the boiler

After all considerations, if you decide you still want to move the boiler, there are few things to keep in mind to make the move successful and flawless. Whether you’re moving the boiler to a different room in the same house or to a new home entirely, here are some factors to keep in mind:

  • For homes with tiled or concrete floors, the pipework has to be run through the wall or the ceiling.
  • The new position of the boiler must meet the minimum flue requirements. The boiler can’t be placed too close to the doors or windows
  • If you have a carpet or floorboards in your home, you should be ready to have them disturbed. They might be lifted or re-laid to facilitate installation of the boiler
  • The boiler should be installed near a drain because it needs a waste pipe
  • If the boiler will be installed in the attic, you need to consider having a scaffolding. Additionally, the attic must meet minimum requirements which include proper lighting, a walkway and easy access to a ladder

Before choosing any particular service to move the boiler, it’s a good idea to check around and see if you can get different estimates. This helps you get the best price possible for the move and you could save yourself some money without compromising the quality of service.

Combi Boiler Fires Up Then Cuts Out…What Should I Do?

A failing boiler is easily one of the most frustrating experiences you have to put up within your home. It’s even more frustrating when you have to take a cold bath in the morning because the engineer has not arrived yet.

One of the most common combi boilers failures is when the boiler starts out fine but cuts out immediately after. It’s a confusing problem because the boiler will show different fault codes which can be difficult to interpret.

Wondering what to do if your combi boiler is having the same issue? This blog could help you with some great tips and possibly even save you some money.

Find out what the problem is

Your first challenge is identifying what the problem is. Some problems are easy to diagnose and others not so much. It’s best to start with the easiest and work your way up to the harder one. Some of the problems that could be causing your boiler to start then fail to include:

Low Water Pressure

This happens more often than you would expect. To protect the boiler from damage, the system will shut off if the pressure is too low.

For the boiler to function, the water pressure needs to be about 1.5bar. If it falls below 0.5bar, the boiler will not fire. Low water pressure can be caused by a leak in the system or bleeding your radiators too much. To check for boiler pressure, all you have to do is check the pressure gauge.

If the boiler pressure is low and you don’t have a leak, the fix is quite simple. Just find the filling loop and top up the water which tops up the water pressure. You can then restart the boiler and it will work just fine.

Frozen Condensate Pipes

Most combi boilers have most of the pipework inside the house. But, if you have a unique set up and you have a source pipe that’s outdoors or goes through the loft, you might want to check if it’s frozen.

This is more so the source of the problem if the boiler is not only shutting down but has some gurgling noises. The fix, in this case, is simple. Just boiler some water and pour on the pipe to thaw it out. Once the flow is restored, the boiler should work perfectly.

Water Feed Issues

Water feed issues can arise from frozen main pipes or blockages. No matter what the cause is, not having enough water flowing into the boiler for heating will cause the boiler to cut off after starting.

Try and find out what could be causing the problem with water feeds. If the pipes are frozen, you can thaw them, but, if it’s a blocked pipe its best left for a qualified engineer to handle it.

Air in the System

If for some reason air has found its way into your central heating system, it could cause your combi boiler to cut off when it starts.

It can be difficult to diagnose if trapped air is the problem. A trick that often works is to check for cold spots on the radiators as soon as the heating is turned on.

Once you’re certain that is what is causing the boiler to cut out, you can iron out the problem by bleeding the radiators. This is a simple task that you can safely do by yourself. You just need to carefully follow the instructions laid out in the user manual.

Fuel Feed Issues

This sounds more like the water feed issue. However, if the water is flowing fine, it could be that the boiler is running out of fuel which is causing it to shut down.

Fuel feed issues are serious and best handled by a professional. If you suspect your boiler is not having enough fuel to function, call your installer or a Gas Safe registered engineer to help you find the fault and fix it.

Faulty Thermostat

If these simple fixes don’t yield any results, it’s time to consider other serious problems that could be plaguing the boiler. One such problem is a faulty thermostat.

You’re more likely to have this problem if the thermostat is old. If the thermostat is the problem, the only solution is to replace it and the boiler should resume normal functions once the thermostat is replaced.

Faulty Pump

A faulty pump will cause the boiler to switch off. The pump is an essential component in the central heating system. It helps to move water around the central heating system. If it fails, the hot water just stays in the boiler and this causes the boiler to cut out.

There’s no alternative remedy to a faulty pump other than replacing the pump. Because you have to take some components of the combi boiler apart, it’s best to have a professional do the replacement to prevent additional damage.

These are some of the leading problems that could be causing your combi boiler to cut shortly after starting up. If the problem is persistent, have an engineer to a check-up to see what other problems your boiler could be facing.

Remember, it’s easy to avoid such problems happen to your boiler by having it serviced regularly and checked often. If the problems are noticed early, you can save money on repairs and the inconvenience of a cold shower in the morning.

How to Repressurise A Boiler Without the Filling Loop

If you own a boiler, low pressure is one of the problems you might have to deal with occasionally. Luckily, you don’t need an expert to help you repressurise the boiler. All you need is your user manual and some will to find the filling loop on your boiler.

If the boiler has a filling loop, things get incredibly easy for you. If not, you have to find a way to add water into the boiler to increase the pressure. There are several ways you can go about this, depending on the type of boiler and repressurisation mechanism in place.

Repressurising using a filling key

Some boilers come with a filling key or filling taps instead of a filling loop. The mechanism of the boiler depends on the age and design of the boiler. But, the operation of the two features is largely the same.

Turn off the power to the heating system

You don’t want to run any risks while filling the boiler. Turn off the power and wait for a few hours until the system completely cools down. If you don’t turn off the system and give it ample time to cool, you could easily hurt yourself.

Find the concealed tray

There’s a concealed tray usually under the boiler. In newer models, the tray might be made out of plastic while in older boilers it could be made out of metal. Gently pull out the tray. You will find a filling key attached to the tray.

Remove the filling key

Remove the filling key from the tray by releasing it from the holding mechanism. Once you have the key in your hands, observe its shape and try to locate a manifold keyhole with a shape that matches that of the key. In most cases, the keyhole is located next to the manifold nut. Gently slide the key into the hold and make sure it fits snugly into the manifold.

Use the key to unlock

You will notice the keyhole has a locked padlock symbol and an unlock symbol. Turn the key towards the unlocked symbol position. Ideally, you will have to turn the key through a 45-degree angle. Once in this position, the key should feel completely secure in the manifold.

Rotate the manifold nut

With the key in the unlocked position, turn the nut (usually located next to the manifold keyhole) slowly and gently to counter-clockwise. One the nut moves about 180 degrees you should hear the water start moving into the boiler system and the pressure will begin rise.

In some systems, instead of the key and nut system, they have two taps which might be located at different locations in the house. One near the boiler and the other might be under the kitchen sinks.

Other systems like a variety of Potterton boilers only have one tap which is usually not near the boiler so you have to try and locate it around the house. Regardless of the system in place, rest assured they all achieve the same result. Be cautious not to exceed the recommended boiler pressure which is usually 1.5bars. If you exceed the pressure, you can turn the release knob on the nearest radiator to release the extra pressure.

Once the gauge hits the right pressure, turn the nut back to its original position followed by the key. Return the key to the holding spot on the tray and replace the tray back under the boiler. Your low-pressure issue should now be solved.

If the problem is recurring, consider having a Gas Safe registered engineer check the system for leaks which can cause the pressure to drop. If there is a leak, it needs to be repaired as fast as possible to prevent further damage to the system.
