Central heating wont stop coming on, please help!!

[johnbonham]

Hi All

We have recently moved into a flat that has a Baxi Combi 133HE Plus boilder and a Danfoss TP4 thermostat system.

Following the end of the cold weather I set the boiler to "summer" mode and turned down the central heating nob to 0. I also set the thermostat to 5 degrees (the minimum) so that it doesn't come on.

The problem is that any time the hot water is run, obviously the boiler starts up, but it is also sending hot water to the radiators (thus after a couple of showers the radiators are red hot). Is there any way to stop this happening, surely if the boiler is set to summer mode it should prevent any hot water going to the radiators?

I could turn off the input to each radiator but I am concerned that hot water will still be pumping round the radiator system?

Any help would be most appreciated!!

Cheers
JB

Chances are it will be the diverter sticking. You can turn the rads off at the valves for now, would leave one of them turned on though to dissipate a bit of heat. Then get a engineer in John Henry Bonham!
