    Comments about Empire Comfort Systems 20,000 BTU HearthRite Vent Free Blue Flame Heater:

    Great product..heats my little cottage up nicely.
    I just wish I had purchased the one with a thermostat, because I'm not comfortable leaving it on all night. Also should have got the one with the fan. I set a small fan on top and it distributes the heat well. I disconnected my very expensive propane fireplace in favor of this little powerhouse. No wasted heat going up the flue.
