We have a larger propane tank (23 gal.) and get between five and seven months between fillings.The tank supplies our range, the Takagi and the rarely used gas dryer. But, realistically, with the Solahart water heating, the range by far uses the bulk of the propane. If you are on-grid then the built-in electric heater of the Solahart is a fairly invisible way of keeping the water hot and minimizes electricity consumption though I would still prefer propane as a backup, it's just so much less expensive over the long run. We dumped electric tank water heaters several houses back as soon as we had gas available.
