How much room do others allow when locating a 40-60 gal Hot Water Tank in a small closet space ?
I normally use 24"x30" interior closet space with the door to the closet on the 30" wall. It leaves room for a 24"x24" drain pan and a big enough door to get everything in.
Thanks Bill M.
The last one I drew had an interior measuremnt of 32.5" x 32.5". It is larger than required, but I wanted to fit a 2'0 door. I do my best to never locate a gas water heater within living space b/c of the fresh air requirements. Some homeowners insist on it though.
