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

Feet insulated only with thermal insulation. I've tried electric heating and that 1500 watt limit just can't heat the room. I ran this propane heater on high for 30 minutes and the temperature in the barn went from 30 degrees (outside temperature) to a comfortable 72 degrees. I really had to turn it down. I was really impressed. Attention - damn wet. Everything in the room was too cold (and well below the dew point of the room's relative humidity), so I had a serious condensation problem. In fact, this is not surprising since water is used instead of burning propane. So while I'm warm, my power tools are wet. This may not be an issue in a 50's home and you want to run this to get rid of the chill in the air. I'm taking off a star for durability because of the cheap aluminum header it comes with. Throw it away. Instead, get cast iron pipe and proper thread sealant. Everything will be fine. Here are the parts you will need if you want to hook this up to a 20# propane tank: a few items. First, it's a hose.

You will need a 3/8" coupling and a 3/8" NPT coupling. Now you will need a pipe 3/8". NPT. I have one long enough to go through my wall and into the underground where I store my tank. Now you need a 3/8" female NPT (I'm trying to remember) 1/2" flare fitting to connect it to the pipe at the bottom of the heater. Don't use that horrible aluminum arch that the heater comes with. You will also need yellow gastight tape to seal the threads. hardware store.
