No, there is an off option for the thermostat. And when working right, it drains zero power. And off the grid means just that; you are not connected to the local power, gas and water grids. You create your own. Certainly one way to do that is to ignore electricity all together, and use wood burning stoves, heaters, etc. And that has been the norm for years. But with all the new ways to create electricity, like solar and wind, you can live off the grid with electrical power as well. But it better be a small home.
Which is my point. It shouldn't be that costly to heat a tiny home, power wise. If nothing else, the game could have a space heater. But it just as easily could have a reduction in power costs to heat if programmed correctly.
