Why does my boiler keep reigniting?
It is usually the result of its ‘preheat’ function. Basically, it’s a way of ensuring that hot water is ready to be used in the taps throughout your home. Although, when the boiler turns off after firing up more consistently, you are likely experiencing short cycling.
Why does my boiler turn off after a few minutes?
If your boiler is too powerful for the demand your home puts on it, then you’ll likely notice it firing up and turning off frequently. The reason an equality between power and demand can cause boiler short cycling is because the boiler will produce more steam than it can condense.
Why does my boiler keep turning off and on?
Low pressure can be caused by a leak in your system. This could be from a radiator, a pipe joint or from underneath your boiler. If you have a leak in your system it’s a matter of time until your boiler turns itself off. Fix the leak, repressurise your boiler and you’re back up and running.
How do I stop my boiler short cycling?
Adding thermal mass to the heating system will decrease the burner short cycling and this can be done by adding water volume to the system. A relatively easy way to add thermal mass is adding a “Buffer Tank”. A “Buffer Tank” is simply a tank of water.
Why does my boiler keep firing up when heating is off?
Pre-heating
You might hear your boiler fire up from time to time, even when the heating is off and you’re not drawing any hot water. This is completely normal, and is there to ensure you have hot water when you turn it on.
Why does my gas boiler keep cutting out?
If the boiler keeps shutting off, it could be due to closed valves, air caught in the system or a broken pump. The boiler is switching itself off due to in-built safety mechanisms – if it did not shut down, then the boiler could overheat.
