Topic: How long on 30 Lb propane tank?

Posted By: MSHappyCampers on 12/11/10 10:26am

We don't do too much cold weather camping so thought I would ask you guys a question that I already realize there is no exact answer for. I wonder what is the average time you will get on a 30 Lb propane tank? Lets assume that the temperature is in the 25-30 degree range and you use the central system at night to keep the pipes from freezing in the sealed underbelly. Like I said, obviously there are so many variables that there is no exact answer for this, but perhaps you have some idea. Thanks!

A gallon of propane is about 90,000 btu. insert your furnace input btu's and it will tell you how long a gallon will last. As an example if your furnace is 40,000 btu, than 1 gallon = 2 1/4 hour burner run time. a 30# tank is about 7 gallon. Hope this helps.

I get a season or more out of a tank, but I don't camp at less than 50 degrees, intentionally anyway. I put tape with full and MT dates on my tanks. Have fun.

Joe and Annette,

Propane is a cost item and in most cases the per gallon cost exceeds the .07 cents avg per KWH electric cost and in some cases where your electric is included in your site fee you save money.

By your signature you have a quality insulated RV so you need to utilize that. We don’t use our propane except to take the chill off on very cold mornings; we use electric space heaters with the ceramic inserts that have the auto safety shutoff switch, don’t use the coil wire type and make sure it has the tip over safety switch!!!. We use a clamp on light to keep our under belly bays warm and we use a power converter from our battery to do some of our AC needs, outside decorations, outside lighting, etc.

Your propane question is pretty well answered by Ron and Charlotte.

Good Luck,
Bill

Being here in AZ from Nov thru Mar, we AVERAGE a tank every 2 weeks
That means we can get as short as 6-7 days , and as long as 20-25 days
Too many variable as to weather, temps, temp u set on thermo etc etc etc to give anything more accurate than that

I only have one example that might help you, we would get about 10 days with a night time temp in the 40's. That only included the cook stove.

If you're worried about running out you could put in a tap, available at RV outlets, and carry a 20# for emergency use.

I have a remote wired thermometer in my underbelly near the FW pipes where the go thru the floor and cross over to the other side of the trailer. Even using electric heat only you might be surprised how warm the underbelly area stays with low temps of only 25 to 30. I would bet your pipes would not need the additional heat, but you should get some way to monitor it to be sure like I did. The few times I have used the on-board furnace to supplement the electric heat it warmed the temp in the underbelly up quickly about 10 or so deg, but lost that heat just as quick.

30 gallon tank, fulltimeing and we probably fill once a year. Obviously we don't spend much time where we need the furnace and use an electric heater on those mornings are a tad nippy. Even at that, I can't remember ever putting over 15 gallons in the tank.

This is about the same experience that I have. I supplement with ceramic electric heaters and the propane kicks in when the electric heaters cannot keep up.

During colder periods I use 1.5 to 2 gallons per day. Last winter I spent the entire winter working in northern KY, had a 100 gallon tank dropped off, hooked up and started using it Thanksgiving week and it lasted till the third week of February, so it made around 11 weeks.

Taking a spare 20 with you is a great idea.

Last Feb in the Fl panhandle we used 1 motor home tank per week. Cost was a bout $75.00. We were told it was the coldest in memory. Warm by Ohio standards and we didn't shovel snow.

i camp a week at a time during hunting season. Night time temps upper teens to 30's and daytime 30's to 50's. Dad is cold natured and needs lower 70's inside while sleeping and upper 60's during the day time. I have 30 lb tanks and have emptied one, but never two even with mostly teens and twenties at night and 30's and low 40's during daytime.


Posted By: skipnchar on 12/11/10 02:26pm

Since you realize all anyone can possibly do is guess, I'll guess about a week to 10 days on a 30 lb. bottle. this assumes you're heating the trailer both night and day and also doing a couple of meals a day on the range top or oven. It also assumes you heat water using electricity and that the wind isn't blowing and you have passive heated holding tanks instead of electrically heated ones and do not constantly go in and out the doors or sleep with the windows open. Now THAT'S a lot of assuming

Since you no doubt have TWO 30 lb. bottles of LP and with the auto switching regulators most everyone has now there's really no reason to carry extra gas. When the glass turns red remove the empty and you've got at LEAST five to seven days to get it filled while using the other one.

We camped about 30 nights this year. About 6 of those were in temperatures around freezing or just below at night(but warming up a little in the day). We used the stove inside some(not every day), and the oven once or twice. Considering all that and the use of the propane to heat the water for showers, we used up one tank this year. At least that is when I noticed it upon returning on our last trip. I do know we were still on the one initial tank at the beginning of the last 3 day trip.

Thanks everyone! This gives me something to start from.

We lived in a 27' 5er with a super slide with R7 insulation with mobile home skirting all around for one winter while the house was being built. We had temps down to zero with 40 mph winds at times. I refilled every third day in those type conditions. Refills were 15 bucks at my LP dealer I use for home heating which was on my way to work.

LP usage ??? Much depends.


Posted By: old guy on 12/11/10 11:46pm

during elk season, two 7 gallon ones don't last very long. I go around and get my friends tanks that don't hunt and stock pile my propane for the furnace for a week.


Posted By: LadyRVer on 12/11/10 07:18pm

Last year in the exceptionally cold winter in FL, in a fifth-wheel, we were averaging a 30# tank refill about every 3rd day. Our neighbor across the street was also on the same schedule. So, basically we were doing 2 tanks a week, using furnace day and night. Have an electric heater which we try to supplement LP furnace, also. In current motorhome, the sun (when out) warms up the MH really nice during the day and LP is for early morning use and evening/night. We are on the conservative side with LP.

Southern Arizona for Thanksgiving week with the days 58-62 and 18-28 at night. We had a ceramic heater that cycled on and off when it was in the 20's and ran all night when it was in the teens. We ran the furnace before bed and in the morning to warm things up and the fridge ran all week on propane while we cooked most meals on the stove. Our 20# bottle lasted 6 days, so 9 days for your 30#. Your mileage may vary.

Driving from Michigan to Arizona two weeks ago, we used 30 lbs of propane the first approx 2 1/2 days but it was really cold and windy. Furnace was on turned low while on the road.
