Why does my heating go off when I run hot water?
The diverter goes into a ‘mid position’, which allows the hot water to flow to both the water tank and the radiators. When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off.

Can a combi boiler run hot and cold?
That is quite a lot to expect from a combi boiler without backup hot water in a cylinder in the attic. If a combi boiler can’t manage all the hot water demands simultaneously, then it gives hot running water priority. Therefore, it may turn the radiators off temporarily, while someone draws water in the kitchen, runs a bath, or takes a shower.
What causes water to come out of the boiler?
This type of blockage will cause the boiler to get up to temperature too quickly which will cut out the burner until it cools and will then fire up again. This causes the water to come out at inconsistent temperatures, hot, lukewarm, hot, lukewarm, etc, etc.
Why does my boiler get hot then cold then hot?
