Review on Mr. Heater Corp F299720 20,000 BTU Blue Flame Propane Heater - Vent-Free, Multi-Purpose by Sarah Clark

Well I had 22p and I put this beast to 3 and it was 70p in less than 10 minutes! Just unbelievable! I won't freeze my ass anymore! In my opinion the best heat in terms of value for money. **Update** I've been using this heater for a year now. It's great for heating a room quickly, but it requires a lot of propane for everyday use. Running is very expensive. It goes through (propane) grill tanks like water! Is the igniter really supposed to use that much gas? I think that's one of the reasons this thing uses so much propane. When the thermostat is running, the check engine light roars like a jet engine! And when someone tries to sleep there is a horrible sound as the (metal) heater cools down and then heats up again. The sound is very amazing!
