I moved into an older home in Minnesota that has hot water heat using an ancient boiler and those monster cast iron radiators. Changing anything about the system is out of the question since the house does not belong to me.
My question is: Has there been any studies as to whether it is more efficient to leave the thermostat at one setting or is it cheaper to turn it down whenever I'm gone for more that a few hours.
When I get home in the evening and turn the thermostat up, it takes forever for the radiators to start puting out heat. But once warm, they stay hot the rest of the evening.
Except for the coldest nights, I don't normally hear the boiler come on throughout the night. (I don't know how often it domes on during the time I'm away, but one assumes that with at least some solar gain during the day, it may not come on much if at all.)
Any help would be appreciated.
For economical sakes, safety, and plenty of warm heat, Install a corn stove with the exhaust run out through the window. There is a window adapter available that works well in rentals or leased facilities.
