4. Respect your boiler
One easily overlooked part of boiler maintenance is simply keeping it clear and tidy. It needs to be accessible in case you have boiler problems, and if it's covered with household items, it could even be a fire hazard.
You should also make sure you don't set it too high. If you do, you're putting your boiler at risk of a problem called ‘kettling’. When the boiler gets too hot, it starts to turn the water into steam, which can lead to corrosion and could cause your boiler to shut off when it reaches its high limit.
As a general rule, it's usually a good idea to stick to a boiler setting of 75 degrees. This point is often marked on your boiler's controls, or it could be represented by an "e" for economy. But if in doubt, always refer to your manufacturer's instructions before you change any settings.
