Boilers are the most common way to keep homes and business warm and with a constant supply of hot water. But machinery like boilers have a lot of parts which make the boiler work and to keep it working in tip top condition you will need to regularly maintain it. There is a lot to be said for preventative maintenance and it could save you a lot of money in the long run. Having an annual boiler service will keep it running smoothly. If you don’t have regular services you will come across issue where the boiler is not working and you will have to get an engineer in to fix it or try and trouble shoot the issue yourself.
If your boiler ever displays an error code asking you to reset the boiler or repressureise it this can be done yourself with the need to call out an engineer. Your user guide can show you have to reset the boiler. If our user guide is missing just type the type of boiler into Google and you should be able to find help on downloading a user guide or having one sent out to you.
There will be times when unexpected mechanical failures happen, this is frustrating but it is likely that one of the boiler’s safety or operational devices is preventing the boiler from starting. Most safety devices have manual reset buttons that need to be reset before boiler can work again. But it’s important to know that continual resetting of these safety devices is not good, so you should contact a boiler technician if you have had to do it more than twice in a short period of time.
Sometimes you need to reset the boiler when there has been a power failure or better known as power cut. This can mess with the settings and cause an error to occur. This is easily rectified by resetting the boiler.
Sometimes high winds can blow out the pilot light. Resetting the boiler will reignite the light on most modern boilers. Some boilers have a burner controller which pushing the reset will restart the boiler.
Modern boilers have emergency shut off systems which will shut the boiler down when there is something wrong. They also shut the boiler down if they are tied to clocks and outdoor temperature so it doesn’t necessarily mean you have a problem. Some of the reasons why a boiler uses the emergency shut-off could be something as simple as low water pressure. There is a pressure bar on the boiler and the needle should be in between the green section. If the pressure has dropped to the red section which is below 0.5 it means that water has been lost from the system and needs to be replayed. Most new boilers have a pressure relief valve which you turn to re-pressurise the heating system. This is simple and can be down by anyone. Just make sure as you use the pressure valve that you only remove enough air so that the pressure bar needle is nicely within the green safe section.
If you are constantly losing pressure from your heating system you may need to consult a heating installer as some parts may have worn and will need replacing.
