We have been using the Steffes in Rusk county Wi. since the small house was built 21+ years ago. About 1400 SF.
We replaced 2 of the 3 original units ( which were still working) to go to digital controls. Bedroom addition got new unit when built about 7 years ago.
All use off-peak power.
We never set thermostat below 50* , heated when we are not there as more a permanent house even though we call it the cabin.
House is extremely well insulated. We built it as such.
Very good system and more economical than one may think.
No wood stove but fireplace.
Unless not insulated, I recommend them.
