I was talking to a local propane supplier about some troubleshooting. He said last winter he had a couple of accounts with 500+ gallon tanks with small demands which had experienced first stage regulator freeze-ups. He said with the same L.P. supply, they didn't have the same freezing issues with his larger usage accounts.
We were having this discussion because I was proposing the same scenario with my own home. He said the tanks were properly purged and methinal added at that time.
Any ideas? We thought that due to the low draw and large wetted surface od the tank the methinal was not vaporizing with the L.P. and allowing the water to freeze in the regulator? He said he changed the first stage regulator which got things back up and running. Also the frozen regulators all had water coming out of them when they thawed out in the shop....
