I have an old propane tank ( thats not good for holding gas ) and i was thinking of cutting the bell end off and using it instead of a 55 gal barrel, the metal is approx 5/16th. I would think at the beginning of a burn cycle it would help cool downward gas faster, but retain more more heat later in the process. has anyone used heavyer outer skins and were there any changes or allowances needed because of the thicker metal.
This will be used to heat a 980 sq ft house. I have only built 1 heater, a 25 gal 6" with a 22 ft heatsink so far so fairly new to this.
Thanks, Denzil
