Propane Consumption

Need some expert help.

I used a 30 lb propane tank (mounted externally) to run my 6.5 cu ft refrigerator. It lasted just under a month. In this same time period, I used the furnace twice to warm up the camper for 10 -15 minutes twice. And I left the teapot on full for about 10 hours.

It seems like it should have lasted longer. My understanding is a 20 lb tank should last a month and a 30 lb tank should last about 6 weeks running a fridge of this size.

Am I right or wrong?

Thats a pretty decent sized fridge - so its consumption rate is going to be much greater than what many of us here experience with the smaller fridges. Also what was the weather like when you were running the fridge for a month like? Warm? its going to eat more propane in warm weather than cool weather.

Another thought is whats the BTU rating on the burner on the stove you ran for 10 hours at full power? - I know that each one on mine is different.

A 20 pound tank of propane contains about 433,000 btu's of energy. Once you know how much your appliances consume, it's simple math. My furnace uses 12,000 BTU's per hour, the water heater consumes 8,800 BTU's/ hour, and my 'fridge uses 1,000 BTU's per hour. I didn't check my stove BTU rating.

Doing the math, the 'fridge should run about 18 days on one 20 pound tank of propane.

It seems a 30 pound ( or perhaps less if not filled completely) with the other uses is about what I consumed.

anecdotal..not scientific, but when I am living off grid using propane for cooking and fridge only (My heater runs of its own tank and my hot water comes from a teapot...) a 20 pounder lasts me about a month. I have an old and small fridge.

Propane Consumption

The big question here is if a propane tank at 50% capacity is half full or half empty? LOL!

No water heater use? Those tend to use quite a bit.

I checked behind the barn and found more than a dozen tanks. Most were old and out of date. Lots had the wrong valves. I too them to Home Depot swapped them all for new tanks with new valves and then took them to be topped off. It is nice to have full tanks. Even so I was burning through 20 lb tanks fast last winter.

I have two 30's I'm using on an external two stage regulator and hose. These tanks are old and the date and weight a have been painted over. I will try and swap these for 29 lb tanks when they run out, or else scrap them. I plan to buy two 40 lb tanks or maybe three for use this winter. I am debating getting propane delivery and renting a much bigger tank.

Long ago in my trailer park days, people coveted the 100 lb tanks as that was the largest size that could be transported (legally) by the average Joe to take and get filled. I suppose they now also have to have the new valve. I was given a really large permanent tank by a neighbor years ago, and it still had propane in it! I have not looked into getting it filled, or if it is even still fillable. It has been painted (silver) but shows significant rust pits underneath the paint. It may end up at the scrap yard or as somebody's grill/smoker some day.

I would like a 100 lb cylinder but then how do you transport it vertically except on a trailer? Then to fill it , it has to be weighed. Getting if is easier than back on. I'd rather have a 20+ gallon fixed tank with overfill protection.

I never had one myself and never hauled one, but did help others get them on and off a truck. I don't know why it has to be moved vertical though?

All propane cylinders have to be carried vertically. If they vent. You want gas coming out not liquid which expands 200 times in volume. Lay it down inside a car ? A big no-no

Are you really talking about hauling a 100 lb propane bottle in a car?

I am a bit surprised to find this is true. See the following URL for more information: http://www.mutualpropane.ab.ca/Porta...eCylinders.pdf

They don't sell horizontal propane tanks in Canada? I see this PDF Dan referenced is a Canadian document. What about big moho's that have horizontal propane tanks? Hummm.

While horizontal tanks exist (I have used a portable horizontal tank with a fork lift) they, like vertical tanks should be transported in their operating orientation for the reason Night Sailor stated. You do not want the vent to dump liquid propane, particularly in an enclosed vehicle.

The motorhome tanks are designed for permanent mounting, and I believe are regulated differently than portable tanks. Some permanent tanks (although not the motorhome versions) have both gas & liquid outlets.

Yes the do but all the vents and knobs etc are not on the very end but on the long side of tank so they vent from the top not the end.

My slide-in camper for a pickup truck had 2 horizontal 20 tanks; think they all still do. Had to haul them in/out to refill.

Yes. I owned for several years a 12' Real Lite, side entry, cabover camper. It had 2 horizontal 20# tanks with an auto switchover valve/regulator. I had to take each tank out separately for refill. They had the valve/controls in the normal place (at the end) but each one had a 'saddle' bracket welded to the side for horizontal stability. Pretty sure that the internal pickup tube was for horizontal use even tho they were filled from a vertical position. Each used a regular POL fitting for filling/delivery connection. We made the Alaska Highway trip with that camper in '93 & I had at least 1 tank filled in Canada (Lethbridge, AB ??)with no problem (rules may have been different then??). Glad I never had to replace either of those tanks as I'm sure they'd have been more expensive than a standard vertical 20# 'bottle'. At most propane dealers they still use a 'quick spin hand wheel' POL type valve for refilling tanks, even the ones with QC-1 valves & the OPD device.
