There is an air bubble trapped in the water pipes the change in pressure causes a bounce which tricks the combi boiler into firing up. Often cured by running the taps to shift the air lock. need a mini shock arrestor and non return valve installed onto the cold feed going into boiler that will resolve the problem.
How do you get rid of an air lock in cold water pipes?
Make sure you achieve a good seal to prevent pressure from escaping. Turn on the hot water for a few seconds, then the cold water, and keep both on for about a minute. Now, turn off the cold water then the hot water tap. Water will fill up inside the hose and pressure should build up to break the airlock.

What is boiler cycling?
January 10, 2020. Short cycling is when a boiler repeatedly cycles on and off. Whilst this is undesireable, it prevents the boiler from overheating when the heat cannot be dissipated quickly enough. It’s inefficient and imposes unnecessary stress on the boiler and heating system.
Why does my boiler turn on in the night?
As for summer, well, that’s a no-brainer, isn’t it? It’s true that boilers do turn on from time to time during the night. Combi boilers work best when the heat exchanger inside is kept warm, so it will need “topping up” a few times overnight to make sure you have instant hot water when you need it.
