Radiator is still on when turned off

duipose Member Posts: 2
the switch is turned off but i am getting heat to my baseboards in one zone. i have 4 zones in the house. but only one. it gets hot, then it stops and cools down and then calls for heat again all with the switch off. when i shut off the boiler it helps for a little while but i need the boiler for hot water. I removed all the wires relating to heat (R and W) from the thermostat, but it still does this. it just happend tonight for the first time.

why would this happen?

    Do you have a picture?

    Does your system have zone valves?

    Is this occurring during a domestic water call for heat or is it calling for heat on it's own?

    Any paranormal activity? Just kidding.

    of the zone piing and wiring would help.

    heat stays on when heat to room has been diconnected


    thank you for your response. i'm not sure about zone valves. right now it has not done it all day. as for happening when the boiler is calling for heat for the hot water? i didn't notice a correnlation but not guarnatee that was the case. for now i will wait and see if it repeats or if it was a fluke
