The fan is a little noisy but worth it. I would highly recommend.
woill see how much oder it puts out & if we need to put a fresh air source in.
Unit is far quieter than I expected. I am not getting any of the pops and pings I've heard on other units of this sort. EDIT: after a few hours of operation it has started making popping noise on cool down, but still is far quieter than my Goodman furnace blower fan.
Given the situation I'll be using this I think I should have got a blue flame unit, but this is nice. Standing beside it is like being around a campfire.
Thermostat is working. Turns on and off as expected. Unit is installed in kitchen of the middle floor of a Chicago 3-flat, 1200 square foot apartment.
It is currently 26 degrees outside. I turned the main furnace off to test this heater's limits.
With a ceiling fan running, the thermostat dial on 2, and a curtain between front rooms and back rooms it is keeping a kitchen, back bedroom, and bathroom and a tad over 60 degrees.
With the thermostat dial on 3 the kitchen temp is slowly rising it had been quite some time and the unit has yet to turn off. Eventually I got impatient and turned the main furnace on to 70 degrees. Main furnace got apartment to 70 and turned off and the Mr. Heater had still not turned off. Would see than 3 on the dial is over 70 degrees.
Not sure it would ever get my apartment up to that temp unless it was warmer or I had better insulation. That said, I'm not sure I'd want this unit in a room that was too sealed up. I'd be hesitant to use this a main heat source given that it doesn't have venting to the outside.
Overall I think this will be great supplemental heat and power outage emergency backup. I also think this unit will pay for itself in two to three winters.
