i hope someone can help me out here?

problem: DHW - when hot tap is opened, it warms up then starts to cool off. the combi boiler burner keeps turning on and off every time the water seems to begin to warm up. it keeps doing this constantly.

i've checked the operation of the diverter valve..checked the diaphram and that is fine, and that the pistons are extending to operate the microswitches and all seems fine. i've replaced the thermistor for DHW and the problem still exists.

central heating is fine, just the problem with the DHW not getting to a hot enough temperature because the burner keeps turning off and on.

can anyone give me any other ideas please?..many thanks

Hi,

 Our heating stopped working today. We've got a Veissmann boiler that's under a year old, and an older Megaflow cylinder, and two diverter valves (all about 10 years old). We also use a Hive thermostat.

 When I boost the hot water with Hive, the receiver near the boiler shows it's...

I've just had a back boiler removed and combi boiler installed and have noticed that my radiators are heating up when using the hot water. I've been told this is due to the residual heat being moved around the system once the hot water is satisfied. But the radiators are heating up as soon as i...
