Small water heaters are good for limited spaces.

Whirlpool manufactures electrical water heaters in many sizes, including a 6-gallon heater. Small-capacity water heaters, like these are designed as point-of-use water heaters and are installed near fixtures where hot water is wanted immediately. They are also installed to supplement a home's main hot water tank when the run of hot water piping to a fixture or appliance that requires hot water would be longer than 70 feet. No matter where you install your Whirlpool 6-gallon hot water tank, ensure you follow all manufacturer safety instructions. Does this Spark an idea?

      Turn off the circuit breaker for your water heater's power receptacle.

    • 2

      Ensure you have the proper clearance and location for your water heater. There should be a minimum 2-inch clearance around the water heater. The water pan must have no more than 2 ½ inches maximum depth and 2 inches wider than your heater.

      Open the electrical junction box cover on your heater by removing the screw with a Phillips or flat-head screwdriver, whichever is applicable. Connect the electrical supply from the junction box to the power supply. Ensure you install the ground wire to the green ground screw and replace the junction box cover.

      Install the cold water supply line to the fitting marked “C”. Install the cold water shut off valve at a point close to the water heater. Attach the hot-water supply line to the fitting marked “H”. Tighten with your wrench.

      Connect the tempering valve between the hot water “out” line and the cold water “in” line.

      Locate the temperature pressure and relieve valve fitting near the top of the water tank. Install the temperature and pressure relief valve and discharge line.
