Question:

why does my boiler send hot water through my baseboards when the thermostat and the circulator are off?

I have oil hot water baseboard heat

Answer:

ithe zone valve may be stock try to close it and then check heaters,good luck.
hot water, like air, tends to rise. you may have this situation. Is it real hot or just warm?
you could desire to ask a pair of questions greater in this issue. whilst did this issue start up, and what paintings has been completed those days that could open the device to air. the respond approximately bleeding air from the radiators is powerful, IF the device has been opened someplace that could have allowed air into the device. A leak, even nonetheless small would desire to do the comparable ingredient. The reason right it rather is that by way of fact the steam condenses, it creates a low tension section, that would fall below atmospheric tension and permit air to be drawn into the device, which might abate steam bypass. Your device rather desires to be saved freed from air. it would be air tight, and at a low vacuum of 5 to ten inches of mercury tension. it rather is how vacuum is measured. A Gage calibrated to study vacuum will do this for you. attempt the device in distinctive places and look at each and all of the readings. you have a blocked pipe it incredibly is inflicting this issue. verify the operation of the burner. The thermostat may be complete up, yet whilst that burner isn't producing complete flame, that thermostat won't be able to help in any respect. yet another element to be certain, the flow pump, is it working exact, if the device has one. ultimately, are there any closed valves, or in part closed valves everywhere.
The boiler is not sending the water, it is the same thing that happens in the ocean... thermal currents, the cooler, (heavier) water settling to the bottom, warmer, less dense water rising. This will circulate like this (if uninterrupted, by start up) until the water temperature has stabilized throughout the system.
