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

What a great little unit! I’m remodeling a house that currently has no working furnace. I connected this heater to the kitchen stove gas line, and it heats the whole house (approx. 1,100 sq. ft., single story). Now I’m able to do drywall and painting without any drying-time issues or delays. Most all the heat simply rises up and mixes with the house air, so the sides & rear of the unit are comfortable to work around. The front is warm, but you can aim that away from your current work area. No more propane heaters for me.
