Is a Nest worth the money?
Is this nest controlling an A/C or a heater? Or both? Do they really use electric heat?

It's a convention of building physics to convert all energy useage to kW (sometimes BTU in the US) regardless of whether its gas, electric, oil, biomass etc. For example, Passivhaus calcs are done this way.

Some people use electric heat in the south. Mine is gas, but I wouldn't mind electric since I use it only a few weeks per year.
