Alternatives to Hawaii Gas

[Hunt Stoddard]

Thanks for all the info. I forgot -- I also have gas dryers in both units, which I'm guessing might actually be the major consumers. They must be electronic ignition, since I've never lit a pilot on them, but I know for sure that the tank water heater has a pilot, but that might be the only pilot in the whole place, since my side of the duplex has electronic ignition tankless (Bosch, which I'm not all that satisfied with, sometimes it goes on, sometimes not).

It all boils down (pun intended) to the tossup between switching tanks and getting them filled, or paying the exorbitant cost of delivered gas.

Ideally, I would like solar heated hot water, gas for cooking, and I guess gas for drying, but I'm not totally sure that's cheaper than electric.
