Hi,

I want to use a 10,000BTU propane, non-vented, wall mount radiant
heater. Having an all eletric home means no gas tank outside.

Can anyone tell me how long I might be able to run one of these at full
10,000BTU from a standard BBQ propane tank.

Are we talking hours days or weeks??

Thanks

If I remember correctly, 1 lb of liquid propane has somewhere in the
neighborhood of 20,000 BTU of energy stored.

A stock propane tank for a grill is usually 20-30 lb of propane so
you'd get a total of somewhere in the neighborhood of 400k to 600k BTU

So if your heater generates roughly 10,000 BTU per hour you should be
able to get around 40-60 hrs of use on a standard "gas grill" type
propane cyl.

This is all, of course, the roughest of calculations and your mileage
may (and probably will) vary greatly.
