Room Temp way higher than Thermostat setting

How many pumps do you have? If you have just one pump, and two zone valves, it sounds like a zone valve is stuck open and continuing to call for heat.

Just a guy running some pipes.

    Room temp way higher than Thermostat setting

    Have forced hot water from Oil burner, with 2 stages (upstairs and downstairs). This problem just started about 4 days ago: Bedroom thermostat set to 65 at night, but heat stays on, and it gets above 80 until I turn off the Burner. Thought it might be the thermostat, so I switched the upstairs one with the downstairs one. Bedroom still getting too warm. Is there a control at the burner that might be bad, or could it be bad circulation w/in the upstairs loop?

    Oh yah

    it sounds like gravity circulation. A zone valve or flow control valve are likely culprits if you have one. Hot water wants to rise. If the downstairs zone is heating and there is a path for hot water to rise on it's own, it will do just that. Go downstairs and grab the pipes and think like hot water. Where would you go if you could. (Paris mayby?) (Sorry ignore my drift) :P WW
