Can anyone comment on propane consumption rate? How long does a 20# tank last. Is a 100# tank more appropriate?

Propane contains 91K BTUs per gallon. A 40K BTU heater thus uses about ½ gallon per hour. A 100# tank holds 23 gallons of propane. Thus about 52 hours of heat from a 100# cylinder (versus 10 hours on a 20 pounder). You often get a price break filling a 100# cylinder over the little grilling bottles. There can be pressure fluctuations when tanks get low thus larger tanks are better. Also, use a two-stage regulator for best results (e.g.; search amazon for ASIN B0024E6TX2).

From experience I have found it consumes 1 gallon per hour, 20 gallon (BBQ) propane tank is roughly 4 gallons.

On small tank at least five batches ,depends on what your frying. Its well worth the propane.

Propane IS LP. LP = Liquefied Propane. I'm not sure what you are asking about the 20psi cylinder. I would guess that 20psi is way too much. The unit comes with its own regulator, so the pressure is controlled by that, not the cylinder. In any case, a cylinder is a great deal more than 20psi, unless I'm mistaken.

Propane conversion is 4.22 pounds per gallon. 100 pounds equals 23.8 gallons

Robert, we have two twenties on line with our heater, but I can't think of any reason why you couldn't use a 100# tank

Pretty much, its the standard 16oz propane bottle thread. I use a coleman with mine but have used different brands. Highly recommend this, pays its self after first trip. 16oz bottles at $3 each vs. filling a 20lb bulk tank for $15. 1/4 of the price if you were to buy 20 small tanks. One tank lasted me 10 days and night for breakfast/lunch/dinner. with 25% left

We use both burners every time we use the grill. We bought our 20lb tank back in mid-March and we are still using the same tank now, April 30th. We grill about 5 or 6 times a week for dinner. My husband does not open the valve all the way because it conserves the propane and still cooks quickly and wonderfully. I would say we still have another few weeks on this tank, at least, which would bring us up to 2 months on one tank....not bad.

Kathleen, I have one of those working on natural gas and it works like a charm! You should have or buy the propane version and it will run on any tank, but if you need to run it on full for an extended time, I would recommend getting a larger tank. If it's a small room however, it is probably sufficient to run it on a low setting and then a small propane tank will most likely last quite a while. So, in a nutshell, it depends... Sorry, that's the best answer I can give you. Good luck and hope you're staying warm.

The tank shown is just disposable. If you are using the heater to heat a garage I would recommend you purchase the hose and adapter to connect to a 20lb. propane tank. Running the heater on high I have been hard pressed to get more than 4 hours per 1lb tank.

Gallons are never referred to when discussing propane. I have never seen or heard of a 5 gal. tank for propane.

You can use 20 to 100 lbs tanks,I have found that a 30 or 40 lbs work the best [ease of movement and time before you have run out to refill your tank] As far as how long a 20 lbs tank will last-At full 60000 btu,outside 20f about 8 to 10 hrs.

Depend on the settings, low medium or high, this heater uses two 1 pound profane tanks or the optional 20 pound propane if you purchase the hose, on low setting it will give you 12 hours and 2 hours on high with the 20 lb propane it will give you over 20 hours on high setting

I checked my manual. It specifies using a 16.4 ounce disposable propane cylinder. There is no mention anywhere of whether a larger propane tank can be used. It does say not to change the regulator assembly and I'm thinking to use the larger tank you might have to. I would say no to that. And the smaller cylinder lasts quite awhile so I'm not sure why you would want to .

My tank does not last 21 days either. First, I would ask the manufacturer. I brought home a newly filled 20lb tank. The tare weight (empty) was 16.6 lbs. I brought out the 2 scales that I own (1 digital and 1 spring type) to see if the it weighed 36.6lbs. Both scales read less that 33 lbs. Of course, my scales are not calibrated so maybe that's the problem. I buy from a trustworthy supply store but I don't know to what extent the propane scale is calibrated or regulated to a standard. The other thing is the 'burn' rate may not be accurately controlled at the factory (call them) so that there may be a considerable variation from unit to unit. I'm still not getting the kill rate I had hoped for in my yard/woods. Yesterday I did an extra fogging using a Black Flag fogger just to work in there.

On a low setting a 20lbs tank will last 20 hrs. On a high setting it will last 8. Heat raises so not much insulation is needed. My tank is 1' below the fire.

The generator comes with a connecting hose & regulator, similar to that used on propane gas grills. I don't know what connector is on 100# LP tanks, but the hose provided with this generator expects the same type of fitting found on 20# and 30# tanks... (I am using a 30# tank with the generator, as I have 2 spare 30# on the RV (~100# of propane, in easy to move cylinders...) My understanding is the 100# tanks are not required to have the newer style TYPE 1 OPD valve found on the 20# tanks used for BBQ's. Your 100# tank will liekly be POL or TYPE 1. If its POL (threads on the inside of the tank outlet, as oppiosed to threads on the OUTSIDE (TYPE 1) You need a converter like http://www.amazon.com/GrillPro-11051-Universal-Propane-Adaptor/dp/B0029T5U0A/ref=sr_1_3?ie=UTF8&qid=1421791690&sr=8-3&keywords=100+pound+propane+tank
