I am brand new to this and wondering how long "approx." will 20lbs of propane last on a master forge 50.15 unit cooking at temps around 225 for brisket and butts. Getting my smoker from Lowes next week ,can't hardly wait..

The masterforge has a 15000btu burner in it. A "full" 20lb tank has 4.7 gallons of propane in it. a gallon of propane equals 91,600btus So, 4.7gal x 91,600btu/gal=430,520btus per tank. If you ran it wide open (which you should not have to do to maintain 250deg) it would give you a minimum of 28.7hrs run time.
WOW that's $2.12/gallon I'm paying $3.59/gallon over here!
Dave....it is worth paying the membership for here. The cheapest I could find around here is at Publix. They let you turn in empty tanks for filled ones for $17.59.
I have 4 tanks....and all are filled. They also check the dates on the tanks and wont fill the ones that are not safe.
In order to keep the costs down, Costco and many tank refill sites have put less propane in the tank. The weight for a full 20lb refill should be about 19lbs of propane, plus the weight of the empty tank (listed on band of tank as "TW" or tare weight.) Empty tanks are aprox 16lbs. so if you weight your tank when you get home. and it is less than 35lbs,... you been hosed Tommy. You did buy a refilled tank, just not a full one.
Barry....it's full. I have an engineer for a hubby...and one that does not trust a "good deal"....lol
He checked and weighed everything before and after. They are filling it correctly.
BUT...it's best to be aware anyway!
Unless you get a deal like Kat, get a fill by per/gallon price and only charge what they fill.
Uhaul does this but shop around each is different.
I fill 5 thirty pounders and two twenty pounders sometimes at once.
I get a price break after so many gallons.
You guys are sooo right. I only go to Publix to return mine now....when the "date" is not acceptable. The only u-haul place that does the exchanges it wayyy far away from the house. After the tornados a few years ago...wont ever be out of propane again. 5 days with no power proved that one.
I know this is not directly related to the question but may help.
