20lb versus 100lb propane tanks

5 posts in this topic

My brother and I are building a fish house on wheels. The heater we are looking at buying is a 20000btu wall mounted ventless heater. We have talked to a few people who have told us it may not operate well on a 20lb propane tank because lack of pressure. Just looking for some more opinions and what size tanks other people use for similar style heaters.

I dont think the pressure is much different in the two tanks if any difference,you have more volume in the 100 but a pressure regulator should do what its for,I've also read a heater runs better off the larger tank,Its hard to believe with a set psi of a regulator there is any difference in supply.I have a wall heater and can run it off 500 gal tank or 20lb. tank only difference is the 20 runs out sooner!Or my buddy heater same there 500gal--20gal--or 16oz bottle they all work the same! cool.gif

Go with the 100#er if you can. The problem with smaller tanks is that the rate of evaporation slows way down as the temperature drops. Once a smaller tank hits about 1/2 full the rate of evaporation has a hard time keeping up with the rate of usage under colder temps. The more surface area the better, and the 100#er will offer that.

Better pressure means a cleaner burning heater and or lights and better btuh availability as well.

If you do go with 20# get an automatic change over regulator and run 2- 20#'s. I was having problems last winter running on a single 20# when it got really cold. This way you know where you sit in regards to propane without releasing the tank from the holder and guessing by weight.

If you are worried about running out, go with two thirty or forty pound tanks and an automatic change over regulator. I run a stove, gas lights, and 15,000 btu furnace off two thirty pound tanks and never have a problem.
