Haven't installed yet, but bought unit for the event the nations power grid goes down.  Unit will be hooked up directly to gas furnace connection to heat our basements, thou have a solar generator, for electric, any type of heat hooked to generator pulls units power down drastically, an unit doesn't have a fan (which really wouldn't matter,they don't draw any power) As long as our natural gas lines aren't affected, we should be able to heat basement well.   Hope I never have to turn it on, but in the times we live in now, you never know.

Pros: Heating with gas
Cons: Unit comes with NO LEGS, so have to mount to wall
