Can the ECO-heater be used to heat a house as a primary heat source?
Typically, ECO-heaters are used for supplemental heat rather than as a replacement for a whole home heating system. While we cannot determine if heating your house with ECO-heaters would be sufficient heat since we are unaware of what your heating needs are. Factors such as: where you live, how large your house is, what is the expected temperature you want the house to be would all play a part in this answer. You can expect an ECO-heater to raise the temperature in a well insulated 10 x 12 room approximately 10-15 degrees. There are a lot of factors that contribute to the efficiency (i.e., windows, insulation, ceiling height, installation of unit, closed room).
