We finally have a 500 gallon propane tank! We had an old 250 gallon tank before, and while it was plenty big when it was just supplying the shop heater, it was too small to keep the house supplied with enough pressure, especially when the weather got really cold.
The new tank is much prettier than the old one too, all shiny white and new. Besides good looks, the split to the two supply lines was done in a much more permanent way, on the old tank the second supply line was just stuck on and the lid couldn't be closed. It was supposed to be a temporary thing, but for whatever reason we couldn't seem to get the old propane company to come back and give us a bigger tank with a permanent two-line hookup. We switched our propane company to Whatcom Farmers Coop, and they have given us great service so far.
Here's to not having to fill this monster very often!
