Benefits of a Black+Decker Tankless Water Heater

Benefits of a Black+Decker Tankless Water Heater

A standard tank water heater works constantly 24/7 to keep that water hot for when you are ready to use it, an inefficient and costly water heating solution.

Black+Decker Electric Tankless Water Heaters eliminate the waste and worry of a conventional water heater, saving you both energy and money by heating water only when you need it.

Additionally, the sleek, compact wall-mounting design will have you regain the valuable space your old water heater took up.




Easy Operation

Easy Operation

The easy-to-use digital control allows you to make temperature adjustments down to the exact degree (in 1-degree F increments) for the perfect water temperature every time.

The flow sensor will sense the presence of water flow and turn the unit on automatically for instant hot water.







Space Saving

The compact, space-saving design requires no venting or gas line, and it can be installed anywhere inside your home or business — in a cabinet, closet, garage, or basement.

    Exactly what I expected. Seems to be a quality product. Only thing I didn’t like was seller shipped in the manufacturer packaging. Though, it is packaged well in dense foam. I cannot comment on performance at this time. Will not have electrical and plumbing in place for another week.

    Works great now, spent an extra 2 hours installing trying to figure out why it wouldn’t work. Checked everything from start to finish but would not power up, finally took the cover off the main circuit board to find the small plug that went from circuit board to the power switch had come loose during shipping.
