A Mr. Heater is a thing that screws onto the top of an LP
tank. They work great in the barn or in a shop but are NOT intended for closed
areas. You would have to leave the door open. They are a radiant type of heat
so they really only seem to heat you if you’re standing right in front of
it. I have one that we use in the barn/shop but it has to be pointed at you
for you to get the benefit. DO NOT use one in your LQ!
