Anyone using a "Cozy" brand direct vent wall heater?

[Brad_S.]

I need to heat a 560 sq. ft. living area. I am looking at propane fired direct vent wall heaters and like the Cozy CDV155 (15000 btu) because it doesn't need electricity to operate. Does anyone have a "Cozy" unit and what are your opinions of it? Thanks in advance.

We have installed a couple @ work. Rattle noises are impossible to stop .Customer finally paid a little extra & got a much better looking fireplace.  ;)
