This heater has performed perfectly running almost 24/7 for a month straight, I bought it to provide temporary heat for an uninsulated house remodel in December in northern Michigan. With temperatures in the single digits it ran all day and night without a single problem, a friend, a painting contractor liked it so much she just bought one too! I just installed it three days ago for her and it is running great!

Great little heater keeps my garage workshop nice amd warm,

I use this in my garage every day.

Perfect for my 3/car garage, thx

I have a 1500 sq ft garage with an 8' ceiling. It is very well insulated because the walls are SIP panels. Stand in Place panels are 5 1/2 inches of styrofoam between 2 sheets of wafer board. Inside of that 1500 sq ft garage, I made a 500 sq ft area using 1 1/2 inch 4x8 foam board that is glued together to make 3 inch walls that are 8 feet high. That way I can keep them up most of the time for a 500 sq ft hobby/exercise room and open it up when I need to pull a car in there or to bring in sheets of plywood to build something. The bottom line is that the 500 sq ft area is heated by the NewAir G56. It comes on about 1 minute every 20 minutes. The temperature stays at 65 and never changes. The blower is a little loud, but I have never seen a garage heater that didn't make noise. For the people that say the temperature fluctuates or the heater runs a long time, I think their insulation is the problem. The heater does not send out a blast of hot air but rather blows a warm breeze. I think that is why my temperature never fluctuates. The heater sits on the concrete floor where the cold air goes and the thermometer is about 5 feet high mounted on the wall. I could not be happier. I hope this comment helps others.

Just a follow up. It has been 20 below zero several times this past week and the heater has run about 50% of the time and the temperature is still constant.
