Sudden drop in LP tank!

[ARCOgraphite]

Here is a plot of propane vapour pressure valve temperature between 50 and 100 F . The pressure goes from 100 to 200 psi, but with time some of the actual vapour goes back into solution.

Looks like you would not have a safety blow off event, (> 2500kPa) that would require tank liquid well above 50 degC. And its hard to add that much heat to ~ 3/4 ton of liquid ... then add in the phase change.

That's a giant tank for just hot water heating. We use only about 12-14 gal over six months for a gas range and oven and my wife cooks most every meal ... and bakes. - Arco

Yeah no blow-off. Besides I was around there all day.

Uses:
HVAC Heater - forced air supplemental with heat pump - off. It does come on for ramp when under say 30°F.
Water heating
Fake fireplace - off
Grill - heavy summer use, some winter use
Griddle - summer use mainly

We have been making it April to April, 12 months, for 3 years now. No complaints. I just wanted back on the top off plan and when I called they would say "Yeah, OK" and never change my plan!! This safety guy who called at 8AM said he would change it.

No suspicion of someone helping themselves to fill up a 20 or 30 pounder?

That would be a serious feat. I mean I would admire the guy trying!! Can't see from any side really. Could valve off and take.....gas?








As he roasts. Oh the song I would sing.

A 30lb tank only holds like 7 gallons.
I don't know if you can draw out of abig tank. Probably can since the local propane company only moves them "empty" or nearly empty.

Truck here, was at ~65% just filled to 80%. 73.4 gallons at $1.99/g. Float had to have been stucko for a bit.

Aside, wow he did a large release. Still stanks.

Might be worth calling your propane provider and asking. That is a big drop.

My bad.

No worries just funning you

I have another use for rubber mallets besides freeing up stuck fuel pumps!

I’m just out here whacking my tank. Mind ya biz.
