I am considering changing the location of my thermostat to "trick" my radiator heating system into keeping the radiators at @ 70 or 80 degrees, which I think will keep the majority of my home in the low 60's. Currently, the system runs infrequently to much wider extremes, causing the house to feel chilly just before the system comes on, and 100 degree plus temperatures in the radiators at the end of the cycle. Would this be more efficient? Would this cause undo wear and tear on my high efficiency boiler/water heater? Would I do better with a different control system altogether? I have a circa 1920's, 2 1/2 story home which could use a window upgrade, but I think by keeping the radiators at a more consistent temperature, I will make the house more comfortable.
