Review on Multi-Functional 10,000 BTU Radiant Propane Heater With Vent-Free Technology By Mr. Heater by Patrick Ceo

I used as an RV heater, it is made well, CO2 shutoff, tip feature; says no need to vent, but I do (small opening). Great if you realize infrared heats objects, then objects heat the air. If your doors open and close a lot, you might not get the most out of this. It puts out huge heat (infrared) but it takes a bit of time to feel it. once everything solid is warm, you can turn it down to maintain temps. I used about 7 gallons of propane every 5-6 weeks in a 22 ft. Travel trailer, nice and toasty, nights down to 26 degrees. Not great insulation, nor did I have dual pane windows. A fan is not necessary in open areas. It just permeates the solid construction and wood cabinets, etc. Some prefer a blue flame heater, which only heats the air. This can be hung on a wall. I shut it off as morning sun comes up, turn it on an hour before dusk. Sleep in light blankets with this unit. This is my second purchase. Highly recommended.
