Propane useage
Does anyone know how long a seven gallon bottle of propane can keep an 8 cubic foot Nordic fridge running. Just curious as the unit is going into storage for three weeks.

Mike, Propane wont be your problem. I assume this is in a RV? those fridge's require 12V power while running on propane. if on 12V you will run out of battery before 3 weeks is up unless you are plugged in. but if plugged in you wouldn't be asking about propane I guess.

All control boards are 12 VDC. Propane just replaces AC for electric element. Usage per day is hard to get a grasp on as it can vary widely depending on model, usage pattern, and ambient temperature. If you search the Internet, you will find reports noting a wide range of rates of consumption.

When we traveled from GA to Seattle and back last summer over 40 days we used only one 30lb bottle of propane for the entire trip. Of course there was a lot of times where we were hooked up to shore power, but all of the travel days and dry camping at rest stops and random locations we were not. I was very impressed that the propane lasted that long on a fridge the same size as the one you are looking for.
I had installed a gauge from a BBQ on the tank and was checking it. Toward the end of the trip though I had to remove the gauge because the restriction was not allowing for the furnace to fire properly. Steve can probably recall some correspondence he had with me during this time, thanks again for the help Steve.
So all in all, 40 days of traveling with the fridge on propane at least 1/2 of the time in addition to propane use for the furnace and stove top we used one full 30lb bottle.

Guess I worded it wrong. Just curious about how long the propane would last. Forget the storage comment.

so that was 40lbs/10 gallons in 3 weeks, but who knows when it was actually emptied.
Right now as we travel we really aren't sucking down that much propane - but mostly on AC power with random day long travel days in between.

Determine the btu input of the unit, then divide that into 91,500 btu per gallon. That will give you a rough idea of hours per gallon if the appliance runs constantly. of course they cycle so you will have to swag that into you calculation.
20# cylinder full will hold 4.7 gallons, 30 7 gallons.
For ex mine is 1500 btu per hour so it should run full bore 61 hours per gallon.
Hope this helps

We just spent 27 days in the Eastern Sierra dry camping. Our Arctic Fox 5ver has two 10 gallon tanks, of course they only fill them to 80%. It went the entire 27 days on the first tank and never switched over to second tank. It also went three full days on the batteries and they were at 80% when we returned. We really do love our Honda 2000i generators.
