Based on the limited exposure I had with a week long rental cabin, the tanks are far too small to provide adequate heated water for more than one occupant.
The tanks will spew out hot water for ages. There just are far too many demands on the thing for it to do a decent job for more than one bathroom. The heater in the cabin was supposed to be three gallon. It was able to give a decent shower experience and no drop when the sink was used as well. But, somebody in the kitchen or a second bathroom would create a significant drop in performance. Add a dish washer or wash machine, and there was more brain power spent trying to map out usage than that instant shot of hot water could provide. The tank was located mid-cabin, so that it served the main floor bath and kitchen. Probably most used locations. The travel to the other bathroom and washroom made for too long a travel down cold pipes. clay > On Jun 26, 2019, at 5:56 AM, Curley McLain via Mercedes > <mercedes@okiebenz.com> wrote: > > SWMBO decided we should throw out the gas water heater and get an electric > heater "so we don't have to light the pilot" This was a bolt out of the > blue.
