Well, the guy from the gas company came, today, and gave the tank a shot of methanol.

He was in the delivery truck, so I had him go ahead and top-off the tank, even though it was only down about 5%.

The next cold spell will tell the tale.

I have never had any problems, ever before, in temperatures a lot colder than what we had when it quit on me.

I will update on the results, as soon as it gets cool again.

Thanks.

 

i took out my calculator and no way your supposed to have trouble at -15 celcius im telling you flush that regulator or have gas guy check pressure at exit of regulator if the only thing he did is put methanol in your tank hes a joke but at least you could get lucky and that methanol will clean it up a bit

good luck

 

With the Maple trees budding, March flowers blooming, and frogs hollering, I guess an update on the situation is at hand.

It may, or may not, have cured whatever was wrong with my propane situation; but, since the shot of methanol, we have experienced probably a dozen more nights with temperatures as cold as the night that I had problems, with no more difficulties whatsoever.

It may have just been a band-aid fix, but, so far, it has done the job.

If I get time, before next winter, maybe I will flush out the regulators and lines, just in case.

Many thanks for everyone's suggestions and advice.

 

I have experience the same symptoms that you have, with LPG forklift units. In that case, the filter/vacuum lock off is freezing up. Not always enough to "frost" the casing, but enough to cause a problem in cooler temps.
Mind you, this even happens inside a warm engine compartment. Take it apart, change the filter, problem solved.

Not sure if this would help with LPG heating systems, or if there is a filter in there somewhere. That being said, I cannot see why there would NOT be one, probably somewhere close to the regulator.

Just food for thought.

 

Thats a good question. Do we have filters in the larger propane tanks? I can't really see where one would be unless it's real small and in or around the regulator somewhere.

Bear, something else you might find, if you do a line change / flush, is a build-up of residue in the system. This residue is what causes filters and converters to clog up and freeze on the LPG lifts. It is normally somewhat dark coloured, and smells like.... well, I'm sure you get the picture. Has the consistency of really thick syrup, or really warm caramel. Disgusting at best.

Good luck with the whole thing, let me know what you find.
