Will the propane last for 3 nights?

Sitting at the KOA in Lancaster PA, and just switched over to the furnace. Propane tank is full and we will only use the furnace at night. We can use the heat pumps during the day. Will a full tank of propane last until Sunday? The water heater and fridge are Also on propane but they donít use that much.

Also proved the the furnace does put heat in the wet bay. It was 39.2 the first time the furnace came on and 45.8 when it turned off

A gallon of propane contains 91,205 BTUs. To make the numbers easy, let's assume you have a 30,000 BTU furnace and it's really 90,000 BTUs. If your 30,000 BTU furnace runs for three hours straight it will burn one gallon of propane.

I do not know if the note about a 37 gallon propane tank is with propane or the empty capacity. If that's the number stamped on the tank they can only be filled to 80% of that amount or 29.6 gallons. Still about 50% more than I have.

We also run the electric fireplace as well because electric is part of the campground fee. The "fireplace" is really a 1,500 watt electric heater.

We also carry a floor space heater of 1,500 watt/750 watt capacity in the basement. On our last trip the furnace blower self-destructed in 35 degree temps and we were there for a few more days. The fireplace kept it at 60 degrees in the main living area but the basement and rear bath were somewhat colder. So we added the space heater when we got back.

HTH,

Ray

Depends on how cold it gets, but when I hunted. We had standard size bottle and it would last us usually 5 to 7 days of use.

Why are you using the heat pumps only during the day?

Heat pumps don't work in colder temps.

The heat pumps are only effective in temps above freezing. At or below freezing the will freeze up and repeatedly cycle not defrost mode. Itís mainly to keep the strain off the heat pumps. Also, when you run the furnace, some warm are is sent into the wet bay. I have a remote thermometer in the wet bay. Itís 31 out and the wet bay was at a balmy 48.

Your heat pumps will operate until outside temp hits about 32, and then it will automatically switch to furnace. So set the thermostat to HP. read the manual. If tank was full you should have plenty for several days. But NOT if you try to keep it too warm. Turn the temp down when you go to bed to a nice cool setting.

If you are at a koa why would you set fridge to run on propane? Is your WH gas only?

It will be getting warmer

I live not far from the Lancaster KOA. It got into the low 20's the last 2 nights but it will be getting warmer the next few days. You should be OK. Like others we use a 1500 watt electric heater and not the furnace. The electric heater has always been sufficient.

Hope you enjoy your stay in Amish country.

I wish. My Airxcel AirCommand units automatically shut down around 45 degrees. Someone said it's because they don't have a defrost mechanism.

I kept the motorhome warm for the last 2 weeks in similar weather in Ontario while replacing the floor.
20 gallon tank propane lasted 7 days.

All three of my Airexcel units perform very well down to around 28 then the air gets cool
