    I've got a project converting a garage into a studio apartment. When the design was originally done we were going to use radiant heat so the architect never spec'd out a place for a hot water tank. That has now changed and we need to find a place for it. Right now the plan is to put it under the kitchen countertop. It's an outside corner next to an exterior wall so it won't be competing visually with other cabinets. Here are the tanks we're considering:

    AO Smith ECL-50
    Whirlpool E2F50LD045V
    American E62-50L-045DV
    Reliance 6 50 DOLS
    GE GE47S06AAG

    The American has the best specs at 31 5/8" tall by 24" in diameter. I'm concerned that there won't be enough room to make the connections to the supply lines. I'm assuming the dimensions are just for the tank and not the supply stubs.

    Anyone ever install one like this before?

    thanks,
    Justin

    Electric water heaters could be condsidered a commodity, like pork bellies. Not much real difference from one to the next. Yes, the pipes almost always come off the top.

    Yeah AO makes one that comes out the sides but it's only 38 gallon. I think we'll go with the American just for being the shortest. We'll just have to have a 90 degree fitting coming right off the tank.

    What is the connection between radiant heat and a hot water tank? They serve two different purposes. One is for space heating, and the other is for "cleaning" uses.

    out here radiant floor heat is often connected into the potable water supply.

    Exactly, therefore, it WOULD have needed a hot water heating unit of some kind, to supply BOTH needs.​

    original design had gas on demand unit for both radiant and potable hot water. without the radiant floor, and subsequently gas, we need an electric water heater.
