Hot water in radiators even though heating is OFF!

[Rackers]

Hi all,

Recently I have noticed that when using the hot water for a bath/shower the radiators upstairs (closest to boiler) in the bathroom & bedrooms start to get hot even though the heating is off and the thermostat is not calling for heat (not in this weather!!)

I have a Worcester 24CDi combi boiler.

Any ideas?

Thanks

You need to call a GSR engineer in to take a look for you. As you have a combi, all the functional parts are within the boiler casing, so need a competent engineer to do the work.

You can post in the Looking For Engineer section of the forum if you don't know a good local chappy
