Propane consumption

[r carl]

I have a Norcold 6.3cf fridge and was wondering how looong it would take for it to drain a #40 propane tank. Anyone have any idea?

Look on the fridge name plate for the number of BTU it uses.
There are roughly 92000 BTU in a gal of propane so you can divide the fridge consumption into this and know roughly how long a gallon will run with the fridge running full bore.
Multiply this times the number of gallons in the tank. I think a 40# tank would be around 9 gallons. The number you get should be conservative.
Assuming 1500 BTU this would work out to about 23 days.


I find I can usually cook and run the fridge for around 3 weeks on a 30 # bottle. That is with out running heat or the water heater

Thanks Rick, so it appears #40 should power my fridge for a minimum of 1 month. That's what i was wondering.

A 40 pound tank, holds about 9.9 gallons.

It should more than take care of your reefer for a month, since the maximum consumption rate, is far higher on cooling, than when the reefer has cooled down, and is on standby.

But, watch out for the water heater. It loves to gobble up the LPG at a rate of not quite 10 times that of the reefer.
