Heating and hot water

[okean]

Does anyone have any idea why my Central Heating always comes on when I have my Hot Water on?

It makes no difference if my room thermostat is up or down - or if the switch on my programmer is on or off!

I've only been moved in 3 weeks and I'm sweating my @ss off every time the hot water comes on?

Any info would be gladly received.

need a bit more info as regards what system you have its poss the divertor valve is stuck so hot water is seeping into the heating circuit

Its a Y-plan system, with Danfoss 3 port valve.

I've tried to manually move the lever at the top, but it seems jammed. So I think that you might be right... the D-Valve is stuck in the mid position, letting water into both pipe feeds.

that would be the problem then

Thanks - Just needed clarification
