A method and apparatus for mounting a water heater on the roof of a building or at another location outside of the building. A roof curb surrounds a hole in the roof, and a base member is mounted to the roof curb. Alternatively, the base member is mounted on a concrete pad at ground level. A water tank is mounted to the base member with the longitudinal axis of the water tank extending horizontally. Support rails are mounted to the base member, and wedge-shaped supports are mounted to the support rails. The wedge-shaped supports are interconnected with tank mounted brackets that are mounted to the sides of the water tank. Thermally insulated spacers are interposed between the wedge-shaped supports and the tank mounting brackets.

Rooftop water heater

A water heater adapted to be mounted on the rooftop of a building includes a substantially cylindrical tank having a horizontally-oriented longitudinal axis. A U-shaped flue tube has a burner end and an exhaust end, both ends being mounted in a head portion of the tank. The legs of the flue tube define a flue plane that is preferably angled 30&deg;-60&deg; with respect to vertical. An inlet tube and an outlet tube also extend through the head of the tank. The inlet tube is positioned at the bottom of the tank and has holes that open downwardly only; the outlet tube is positioned at the top of the tank and has holes that open upwardly only. The tank is weather-tightly enclosed by a cabinet. A base member of the cabinet is supported by a roof curb and supports the water tank. The base member includes a drain opening for draining water from the inside the cabinet to the sewage system of the building, and a water pipe opening through which extend a plurality of pipes communicating with the tank. A grommet weather-tightly seals the pipes with respect to the base member.
