Review on Natural Gas Heater: Mr. Heater Vent-Free 20,000 BTU Blue Flame - Multi-Size Option by Brian Henley

This is my 2nd Mr Heater and they seem like quality products. My other heater is the 30,000 NG heater. If I had it to do over again I would have purchased the 30,000 instead of the anemic 20,000. The 20,000 is ok for a small room of let's say 300 sq ft., but if trying to go through a door opening into another room forget it. The 30,000 can be turned down pretty low and it heats a 300 sq ft room fast, but perhaps too warm for some.of course you can then just turn it to pilot. Strangely these heaters don't push the heat out front like you might think, but shoves the heat out of the lovers upward towards the ceiling. I don't have a fan so can't say about that. They are a little quirky to get started as you can't tell if the pilot is on in a bright light.so start it up with a darkened room. There is hardly any heat on the sides, back or below.just up through the lovers and it dissipates so that the ceiling doesn't get hot. No problem with Co2, but I have an airy house with mild winters on the Oregon coast. Hookup was easy and the quick release hose allows me to move the unit around.even one room to another that has a gas line. It came in a heavy box in good shape. The directions are probably overdone for the apprentice, but a technician would salivate over it.
