It's OK

it's 19 degrees outside, the unit is about 7 feet from the desk and sofa. it feels like 75 at the desk and sofa. it is and has been on a low setting all day. temp reads 59 directly behind the heater. the other rooms are freezing. it makes noises like sheet metal warping when it turns on and off. so far, it does not get hot enough to start a fire. it doesn't take up much space and can be mounted on the wall. i will have to use the furnace to heat the other rooms when company is here. the warranty if good for only 1 year.
