What to do if my boiler radiator stops working
If your boiler radiator stops working it can be an extremely frustrating experience. As radiators are essential to heating your home, a broken one can leave you freezing in the cold.
Sometimes, there may be no visible signs of water leaking from the boiler instead there is a faulty part on the radiator that should be replaced.
In this article, we discuss the most common household problems which cause radiators to stop working and provide some handy tips on how to fix them.
Why are boiler radiators important?
If you're wondering why boiler radiators matter, it's important to know that they provide heat throughout your home. If every room in your house is warm and comfortable, no one is going to complain about the cost or hassle of using a boiler.
By contrast, if only one room in your home is warm and comfortable - while the other rooms are freezing - nobody is going to be very happy. Your boiler radiators provide comfortable warmth throughout your home, so it's important that they work properly.
Common radiator problems
The common radiators problems include:
If your boiler radiator stops working, it is possible that there are problems with either the radiator itself or with the heating system. If you have any trouble getting hot water into your home, then it might be a good idea to call a qualified heating engineer to inspect your boiler and radiators.
The first thing you should know is that there are two types of common radiator problems - those caused by the system itself, and those which come from something being wrong with the specific radiator. If your boiler radiator stops working completely, you will need to determine which type of problem you have.
What do I do if my boiler radiator stops heating?
If your central heating is still working but one of the radiators has stopped giving out heat you should first check if it's switched off at the main or turned down. If you can't figure out what's wrong with the radiator, call a qualified heating engineer to inspect your system and radiators.
What do I do if the specific radiator continues to remain cold?
If all of your radiators are working apart from one and it shows no signs of coming back on, this usually means that there is something wrong with that specific radiator. The most likely explanation is that the part of the system connected to this radiator has either failed or needs bleeding.
Why are my radiators are not getting hot?
Faulty valves can be responsible for this problem. If you're sure that no one has turned off the central heating system at the main, call a qualified gas safe engineer to inspect your heating system and radiators.
If this doesn't solve the issue with your radiator, it is possible that there is something wrong with either the radiator itself or the boiler. This is something that a gas safe engineer will be able to detect and fix. However, we would recommend getting it checked out sooner rather than later to ensure that you don't run into any further problems.
The thermostat could be faulty or incorrectly set. Check the settings and test if this solves the problem with your radiator.
If the boiler is coming on but there's not enough pressure for hot water to get into your radiators, this means that you'll need a boiler service. We recommend calling a qualified gas safe engineer for any repairs or servicing.
How would you clear a clogged radiator?
Step 1: Turn off your central heating system.
Step 2: Unscrew the radiator cap and let any water drain out. Then, using a plunger or plumber's helper rod, scoop out any debris from the inside of the radiator. You can use a wire coat hanger to ensure that you have removed all of the debris.
Step 3: Turn on your central heating system, allowing hot water to flow through the radiator again. The radiator may take a little while to heat up, but should soon start releasing warm air into the room.
How do you bleed a radiator?
Step 1: Turn off your central heating system.
Step 2: Find the air valve on your radiator and unscrew it, allowing any air inside to escape. The water should start draining out of the top of the radiator. You may need to hold something under it to catch any drips.
Step 3: Refit the air valve in the open position and turn on your heating system, allowing hot water to flow through the radiator again. The air will be pushed out by the expanding hot water, which should help it start releasing warm air into the room.
Why is my radiator not working even after bleeding?
If after bleeding your radiator it still doesn't work, it could be one of several things. The first thing to check is that the water valves are turned on and hot water is being supplied through them. If you've turned on both supply valves but only cold water comes out, it's likely that there's a blockage somewhere in the heating system or the feed and expansion tanks. The only way to resolve this issue is to call a professional heating engineer.
What is air in my central heating system?
You may find that after bleeding your radiator, you still have air in the system. This can be frustrating but it is not always difficult to get rid of. If you bleed the radiators and there is still air in the system, you should turn off the central heating pump.
What can I do to keep my radiators working regularly?
When you keep your system well-maintained and carry out regular cleaning, there is less chance of air blocking the flow of water through the heating. It's still possible for air to arrive in the system at times, but you should be able to get rid of it by bleeding air from your radiator.
Do not allow debris to enter your tank or boiler. You may find that leaves get into systems because the flue is not well maintained. These can damage radiators and boilers.
If you find that your boiler is leaking or radiators are not giving off heat, you should get in touch with a professional plumber. They will be able to repair the system and get it working properly again.
If you do not deal with any of these problems, they can become worse over time. The water pressure may decrease or air bubbles could get trapped in the system, which can stop your boiler from working at all.
You do not have to wait for cold weather before you notice that there is a problem with your heating. You will want to deal with any issues as soon as possible so they don't become worse.
