You are correct. What I meant was boil. At minus 43C or there abouts it remains a liquid so can't be burned in a propane modified engine. In cold weather use they add pre-heaters but mostly they don't work well until the engine is running hot so many keep the gasoline and carburetor so they can switch over when necessary. There are also places where you can't buy propane for automobiles or where it is hard to find a supplier so keeping the gasoline equipment provides that better versatility.

Dale, Not to be picky, but propane freezes at -310F, -190C boils at -44F, -42C.

Propane freezes at something under 40 below. It is a problem for our propane powered automobiles and many keep the gasoline operation and tanks for those situations when the propane won't flow. Some also use heat to keep it flowing once the air flow of vehicle movement adds to the cooling. The decompressing gas acts like a refrigerant just as happens when gas is compressed then allowed to decompress in a fridge or air conditioning device.

If you get a tank for heating, it has to be I seem to remember anyway, at least 10 feet from the house. Propane won't freeze unless it's exposed to oxygen and then it will frost the opening closed. When exposed to oxygen, it is way below zero. I've never looked it up but it's cold. The guy that drove the delivery tanker for the company I worked for was attacked by 2 big dogs once and he gave one of the dogs a little blast of propane on the nose. That was more than enough to run the dog off. The knock against propane is the explosiveness of it. And there is no arguing that point. The problem is, carelessness and ignorance of people mixing with the explosiveness of propane and then you really have a problem. Hey here's something probably only you can appreciate. A guy was getting ready to make his first solo sky dive. As he went out of the plane, he suddenly forgot everything he had learned. As his speed increased on the way down he kept fumbling around for the rip cord. When he looked down, he saw a guy coming up at him from the ground. He yelled to the guy :Hey! Know anything about parachutes?" As the guy went past him he yelled "No! Know anything about gas grills?" ----- Original Message ----- From: Dan Rossi To: blindhandyman@ <mailto:blindhandyman%40yahoogroups.com> yahoogroups.com Sent: Thursday, January 14, 2010 9:24 AM Subject: Re: [BlindHandyMan] wireless bad thing detectors. HMM, you learn something every day. I didn't think propane would be a good heating source for a hole house. Everywhere I've lived, you either heated with natural gas or fuel oil. So, when you heat with propane, are the tanks inside the house? I mean, doesn't propane have issues if it gets too cold? I mean, doesn't it start to have problems vaporizing? Anyway, here are the make and models of my alarms.
