I would have no problem using Mitsubishi Hyper Heats units as my only source of heat in the Lakes Region of NH. As a matter of fact I do in an efficiency unit I built a few years ago above a garage. Absolutely zero issues in the coldest of weather! They are 100% efficient to 5 below zero and continue to throw heat (at a lower efficiency) to 22 below zero. Good insulation is the key!
