Rated 5 out of 5 by from Nice Heater I had an electrician come over yesterday and install the 20 amp 240v. I had the heater on low / automatic with the outside temperature at 34 degrees. I sat in the garage watching tv in a short sleeve shirt. It is the correct unit for a garage or workshop.

Rated 5 out of 5 by from Economical and does a great job. I bought this last year and love it and I will be using it against this Winter. I no longer have to avoid the garage when it turns cold! Does what it says and you can't beat the price.

Rated 4 out of 5 by from Packs a lot of heat in a small form factor. When I first plugged it in I was disappointed. I expected that at a 240v the heater would throw out a very high temperature. What it does instead is much better; it move a lot of air fast so it DOES put out a lot of heat, but distributed through a lot of air.

Rated 5 out of 5 by from Review-the hot one bought this last fall to help keep our old house's living room 'warm.' worked beautifully all winter. had it set to low heat and not very high on the setting. there are several other cadet in wall heaters to help keep our old house here on the farm around 50 degrees inside; unless we do some craft/hobbies and then we build a fire in the quadrafire wood stove. this heater worked beaufifully.

Rated 5 out of 5 by from Nice Heater I have a well insulated double garage. It does a great job of warming the space. I really like the fact that it is so quiet. I hung from the supplied bracket near a 220 outlet. Works great
