Wow, a 1000 gal propane tank is humungous! We’re just in a typical suburban neighborhood. One time, just for grins, we got a rough estimate on how much it would cost to get a 500 gal. propane tank installed, the largest that we could fit in. Including reconfiguring the house for it, $15-20K, plus whatever we’d pay for the generator. No doubt it’d be even more now! Problem is there is no suitable space to bury the tank anywhere near where the electric panels are. There is really only one place it could go, actually, and naturally it is the most inconvenient, farthest away place.
We have a friend who lives on substantial acreage and has a 1000 gal tank. She says it is extremely expensive to fill, but worth it to her because she lives alone with nearest neighbors pretty far away, and the generator is always on standby. We will have to stick with gas, though! ;-)
Totally understand. My hubby has been a lineman for over 40 years. When the storms are bad, he can’t get home to help with problems. It gives us both peace of mind. Have gas stove, frig in basement that’s propane and hand pump on the well if needed.
