Interferring Radiators With Hot Water System

zoemichelle · May 13, 2009

We have a Drayton Lifestyle LP522 in our property. As the summer months are coming we have decided to switch our central heating to "OFF" on the control panel. Since doing this, we have noticed that when our hot water comes on (which is set to "TIMED" to come on once in the morning and again in the evening) the radiators heat up as well!

We have tried reseting the system at the control panel and still the radiators heat up.

How can we stop the radiators heating up when the hot water comes on?

Could be a wiring fault, faulty component or incorrect plumbing. Need to know control system, how long you've been there etc.

As Mike says it could be loads of things.

We have to have some idea of how your system works to get any further. If we know what sort of boiler or the name of the one you have fitted, then that helps, because we can usually get some idea from that.
If we know its a combi for instance then we can think in combi terms. If we know its a sealed system boiler, unvented hot water, open vented, solar heated, ground heat pump, air heat pump and so on, it helps us a lot.

You could always post a picture of the pipework or the boiler, it might help. 🙂

Yea but it is almost certainly a motorised valve stuck!

Could be other things too i suppose . . .

Still you aren't going to be to fix it yourself - best call a plumber!
