My water heater is an old electric under the counter type. We recently had
it repaired but it will probably need to be replaced sooner or later. I
want to build a small lean-to building, probably 2x4 or 4x4 feet square to
house the new water heater and also use as a small tool shed.
-Plan on pouring a 3.5" concrete slab, a little thicker around the edges.
-stick frame construction with masonite sheathing.
-some type of insulation (undecided)
I am in the mid-atlantic region so weather is mild year round. Hurricanes
would be the biggest worry but the building would be sheltered from the
worst of the wind by the house (but don't worry I'll make sure to attach
the building to the foundation!). The only real worry would be heavy rain,
mild flooding (couple of inches) and possibly a heavy tree limb falling on
it. The building would backed up against a brick house.
I'm building the shed, running the electric and a plumber will be hooking
up the water heater. (I'm a terrible plumber)
What do I need to worry about? The slab settling and breaking the pipes
loose? Insulating the pipes between the shed and the crawlspace? (Our
waterlines run through the crawlspace) How much space do I need around the
water heater?
I'm working on a job right now where the contractor has
installed a natural gas tankless water heater on the
outside wall of a restaurant. The main thing you must
consider with tankless heaters is "rate of flow" me and
my friends install them with ball valves which makes
adjustment of the rate of flow an easy task.

with a tank type no flow limit is necessary or desierable for that
matter.

electric tankless are a waste of money ...

Me and a friend installed a very interesting tankless heater
manufactured by Bosch. The unit had a little paddle wheel
generator that ignited the pilot light then main burner when
the water is turned on. It supplied endless hot water for a
beauty shop.
