Has anyone poured water over a tank to find the propane level? I have & it works. The propane chills the water forming a light frost.

I have the LP tank cover over mine, I think I'd have to remove that to see the level. I think that the propane will get cold only if it's in use, gas is leaving the tank, like when the furnace is running. Is that when you are able to see it?

I just use one tank at a time, running it to empty then switching to the other. As soon as one is empty I take it to get filled unless we're getting ready for a long trip, then I'll fill it again when we arrive. That seems to work best for us, I never worry about running out.

Full time currently on full hookup, so fridge runs on 120ac. We use the hot water (generally off when not needed), furnace (when necessary) and cooking.

We only need the furnace when our electric heater cannot keep up (generally below 50F). Using the electric did help to significantly reduce the furnace usage when colder.

At the coldest in the winter in Vancouver (20F for a short spell, generally just above 32F at night and in the 40s in the day) a tank lasted one week on average. We did skirt for the coldest months which helped a lot with floor temperature but didn't seem to make a big difference on propane usage.

In warmer months a tank is lasting a month. The last refill was 3 weeks, I expect from here out it will be 4-5 weeks each time.

I periodically check the indicator that tells if a tank is empty (but not how much propane is in the tank) and refill the empty.

Rich, can you clarify. You're in camp and on AC. The WH is switched to Ele (on our 20, we have dual switches in the bathroom, 1 for gas and 1 for ele and the light goes out after ignition). Are you saying that when hooked to AC and heating water with AC, that when you run out of propane due to heater usage or whatever, that the light in the BR turns on and stays on?

I also like your idea of not topping off tanks before a trip to save in hitch weight. Propane is so available I can't see the need for having two full tanks while on the road.


On our maiden voyage in Jan/Feb from Eugene to San Diego...we used about a tank and a half, but ran the heat a lot. I was originally thinking the regulator would switch over, but now understand it the color that switches, the lever switch is manual.

How do you know you ran out of propane? I assume when you have no more hot water?

If I use propane to run the fridge only, for example, how long will a 30 lb tank run? Are we talking 1 day? 1 week? 1 month?
FCStreamer, I tend to save links by category that I think I'll refer to later as opposed to the AS search function.

Here are some threads I had saved and you may find useful. I'm color blind and I think I'm going with the 2 gauges in....KISS

My water heater is not electric, just propane. We turn it off at night. When the propane tank is empty the ignition light just stays on because it didn't light the propane because the tank was empty. Switch over to the other tank and flip the switch, light goes out, water heater kicks on. I never keep the propane switch on both, just one tank or the other.

The regulator does automatically switch (or at least mine does). The lever points to the "primary" tank. Once the primary is empty the regulator switches to the secondary tank, but the lever remains pointing at the empty tank. Unless the secondary is empty you should see no disruption to your propane use when that happens. To refill, change the lever to point to the secondary tank, which then becomes the primary tank. Disconnect the empty secondary tank, refill, repeat.

Easiest way to check propane tank level is to pour hot water over a small section of tank wall
Tank wall in Gas space will be hot
Propane level will feel cold
Try it

Here is a simple chart:

Full - 56 lb
3/4 - 48 lb
2/3 - 46 lb
1/2 - 41 lb
1/3 - 36 lb
1/4 - 33 lb
Empty - 26 lb

Rich, thanks. It sounded too easy but makes perfect sense with a propane only WH.

I pretty much only use the propane for cooking and the refrigerator when on the road. Seldom if ever use it for the furnace. I get close to 6 months or more on 1 tank.

Steel

I believe an equivalent 30 lb aluminum tank weighs about 8 lbs less.

Any propane tank should have the "tare weight" (often abbreviated TW) stamped on the top of the tank. Anything above that weight should be propane.

The people who fill the tanks use this to tell when the tank is full. They set the tank on a scale and fill until it reaches the proper weight (TW + 30# for mine).
