Just a note: I refilled two gas grill bottles Monday at $2.19/unit, 7.7
units. (I don't recall if it was gallons or pounds.) About $18 & change.
In California. At ACE Hardware.

If that is for both, not a bad price. Tonight I filled mine at BJ's for
$7.49. Non member price is $12+

In the course of the winter, I use maybe 4 or 5 bottles.

I haven't filled mine in a long time, so don't know prices, but I do know my
shop, which is 25 x 48 with an 8' 6" ceiling (I screwed up the 10' would
have been much better) flat eats propane on cold days. I have a 35,000 Btu
catalytic heater and a 15,000 Btu model, and often had to run both to get it up
to working temp in the a.m. Working temp for me is around 55-60, but if I'm
gluing it is 65 to 70, as it is for finishing. But I don't like spray residue
floating into glowing catalytics, so I ran it up near 75 or sometimes 80, and
shut down the heat before finishing. That eats at least a 20# bottle (4
gallons?) each day.

This winter will be cheaper, if all goes well. Set the furnace at 50 and leave
it until I'm in the shop.

We'll see.
