Why is my boiler firing up all the time?
It could be a component, such as the heat exchanger or an internal thermostat, in which case you should not attempt to fix it – call a gas engineer who will be able to assess the situation and recommend a repair or replacement. Making sure your boiler has its annual service should prevent this stop-start pattern.
Should you turn off boiler?

Why does my boiler come on at night?
It’s true that boilers do turn on from time to time during the night. With a system or heat only boiler, it’s the cylinder that gets heated up when its temperature drops and the thermostat tells the boiler to fire up (assuming it’s not on a timer). Many people don’t really use much hot water from the tap, either.

I noticed that when I put the temperature down on the thermostat, the heating stops and doesn’t come on- so this is working fine no problems. However, when I put the temperature right up, the boiler does start running but it runs for about 30 seconds then stops for 20 seconds then runs again. It does this continuously.
