The Heater

Here are the requested pics of my heater.

I keep it at 65,000 BTU (or low), at that level
the heater uses a tank every 6-7 hours. With
and average tank refill going for about $20, that
the cost about $3/hours to heat.

For ventilation, I place the heater in the doorway
while it is in use. Propane heaters produce Carbon
Monoxide while heating.
