In my case, the propane was in various sized tanks from 100 gal Pig tanks to 1000 gal tanks depending on access. The most remote ones we used 100 gal pigs (14 per site ) and used helicopters to fly the propane. Made for more trips but the cost of the helicopter to fly big tanks was horrendous.
Tanks were out in the weather but the lines and regulators were either in the shack with the TEGS or covered and insulated. Average winter temp without wind was about –10 F dipping to about –45 F. Not sure what the wind chill was. The people that bought the system augmented it with solar and wind (varying success with the wind as they could not keep impellers in the generators). It has been a couple of years so I am not sure of their present configuration or success.

Propane won't create gas pressure below -43.6F and many propane gas pressure regulators will ice up and stop working below about +20F. This isn't a problem for many locations but it is still important to know what the limits are.

As long as there is propane, they work. No moving parts, very little maintenance. It doesn't matter how cold or hot it is, they just work . Simple power that provides heat for the radio shack as well. Terry -----Original Message----- From: D.
