Expected propane usage from water heater

[ConnieSH]

While you're on the subject of Hot Water Heater......I was just sick last fall after realizing (after we made the deal) that the HWH was gas only. I was sick all over....we have bought several TT and all had been electric and gas. Anyway my question if anyone knows....how long will it take for the gas to run out heating the water only? I know it is a crazy question, but I'm taking the grands to the beach and my husband is taking TT to beach for me. I just hate to have to worry about not having hot water!! Yes, I know we are crazy for not finding out sooner that it was just "gas only" before we made a commitment.

You can run the hot water and fridge for quite a while. I go through a bottle in about 4 months.

Had two switches on most. One is behind water heater pipes, get your manual and read up on your model
