How to Install a Tankless Water Heater

Installing an Electric Tankless Water Heater Made EasyTankless water heaters are now selling like hotcakes as they are now America’s most popular method of heating water.  However, the challenge of achieving an ideal tankless water heater installation is also playing a large role in order to get things right.  To ease up common technical terms of installation procedures, here are some simple step by step instructions for you.

    • Remove the hang bracket from the back of the water heater and hold the bracket against the wall in your desired hanging location.  Mark the wall were the three mounting holes should be located.  If you are on a wall stead, screw the bracket directly into the wall.  If not, insert the supplied walled anchors and screw the bracket into the wall anchors.
    • installed-tankless-water-heater-225x300Remove the four (4) screws and washers to free the front cover.  Lift the front cover over a few inches. Don’t pull too hard. Disengage the plug connecting the LCD panel to the unit. Remove the cover and set aside and then hang the cover on the wall bracket.  Be sure that the unit is hanging securely from the bracket.
    • Connect the power supply (usually at the lower right side of the unit) into the terminal block.  Make sure that the wires make full contact at the terminal block and that the screws are securely tightened.
    • Reattach the LCD cable and then replace the cover of the unit.  Improper contact of the wires to the terminal block s or loose terminal block screws can cause electrical failure.  Do not connect power to the circuit breaker until the plumbing connections are made.  The water connections on your tankless water heater afre ¾ inch FIP and should be connected to the water supply using a standard ¾ inch metal hose.  Be sure to use rubber washers to have a secured seal.  It is recommended that a valve should be installed at the unit supply so that you can turn off the water supply when needed without shutting the rest of the supply to the pump.
    • Wrap all pipes with Teflon tape.
    • After the water connections are made, you should turn on the hot water valve.  Once the water is flowing consistently, check for leaks and correct if necessary.  If the water pressure exceeds 150 PSI, a pressure relief valve must be installed.  At this time, power can be connected to the circuit breaker and make sure that the switches are in the “off” position.

Now that the unit is finally installed, you are now ready to begin enjoying infinite, instant and energy efficient hot water that tankless water heaters provide.
