I just bought a ceramic electic space heater. Assuming it runs constantly 15 hrs/day on cold days at $.10/kwh, that's $2.25/day. If I can cut an average cold day of heating my house from $10./ day to $5./day by using the ceramic heater only in the room I'm in and cutting the household temperature to 50 degrees, I'm guessing I could save $2.75/day.
OK, so this is just BS armchair calculations.
My question is, has anyone tried this approach and does it work?
There is some validity to your suggestion, but it is not 100% perfect.
Some of the heat will filter into other rooms adding to the cost of running the space heater. The cost of the other heat source will be a factor also. If the hourly rate for that heat is much less, the savings will be less. My own experience is that the electric bill went up quite a bit, probably not enough to justify the effort of moving a space heater around.
In my area, electric heat is too expensive to have a big saving. YMMV, but worth some experimenting. Ed
