Is that 'electric furnace' a heat pump type or coil type?
It's a coil type.
I wish I had thought of this before. Now I can leave on all the lights and appliances I want.
Resistance electric heating (coil type) is very expensive to run. A heat pump uses about 1/3 the electricity for the same heat unless you are pretty far north. There are now window AC units with true heat pumps in them for under $1000. They may pay for themselves in one heating season.
