where would be a good place for a hot water heater in my 20x30 single story, i didnt see a designated area in the plans.
See the booklet that came with the plans. "20' plan notes" on P. 2.
Some folks have also used an undercounter unit in the kitchen corners. If mounted on the right side with a panel on the dining area side it will be easier to service.
Thanks John
We built/still building a 14x30 the bath is 5x10 I built a closest in the bath put a full size water heater in there and put storage for towels and bathroom supplies above it.
