We in the 21st century live a much more comfortable life than those of our ancestors who had to endure cold homes and chilly nights. We savour the fact that we can ramp up the heating in our homes and run a hot bath and bask in bliss… until the boiler decides to completely shut down, the warmth evaporating. Luckily, there are some things you can do to get your boiler back in working order.
Then you are in the right place! Keep reading to find out why your boiler switches itself off.
Boilers need a sustained amount of water pressure, in order to run properly. If the pressure is too low or too high, the boiler will turn itself off. Boilers usually run best between 1-1.5 bar units, so check the gauge at the front of the boiler to make sure that the pressure is normal.
If your pressure is too low, it could be because of a leak somewhere in the system, or because you recently bled your radiators.
Spotting a leak is easy, just look for any damp spots underneath your boiler, near your radiators or around any connecting pipes. Epoxy putty can be a great temporary fix for leaky pipes, but something more substantial like clamps will be more permanent. They are also quite simple to fit.
Unfortunately, if the leak is from somewhere within the boiler or the pipes that surround it, you will need to call a gas safe engineer to fix the problem, as it would be illegal for you to do it yourself.
After fixing any potential leaks, the next step is to repressurise the boiler. Repressurising is usually a simple five-minute procedure, but do check your boiler’s manual, as there are different models, which may require extra steps in repressurising.
If your boiler keeps losing pressure, calling an engineer would be your best option, as you may have an internal problem with the boiler.
Thermostats are very useful, being able to monitor the temperature of your home and adjust the central heating based on your temperature preference. However, if your thermostat is a particularly old model or faulty, they may not be able to accurately determine the temperature. This can cause your boiler to fire up and then cut out when it’s not supposed to. The best way to fix this is to simply replace the thermostat.
There are a variety of different thermostats available, with the most basic ones available at a very reasonable price. You can also opt for a smart thermostat, which offers a range of benefits. Some are able to learn your habits and monitor which rooms need the most heating and adjust accordingly. This can save you money in the long run, so if you are able to put up the actual cash, a smart metre can be a lifesaver.
During especially harsh winters, a small pipe on the outside of your house, called condensate pipe, can become frozen. The pipe carries the acidic water away from your boiler and deposits it into a drain. When the pipe freezes, the water inside also gets frozen, which can cause water to get backed up into the boiler. Eventually, the boiler will shut itself down in order to protect itself from damage.
Check your home’s condensate pipe to make sure it’s not frozen. If this is the case, relinquish their icy bonds with some warm water and reset your boiler.
If you have problems locating the condensate pipe, check out our dedicated post where we explain where is the condensate pipe on a boiler.
Another problem that appears frequently is trapped air in your boiler system, which can lead to an increase in the boiler temperature. As a result, it will shut itself off. To alleviate this problem, you should bleed the radiators around your home:
