BLACK+DECKER 27 kW Self-Modulating 5.3 GPM Electric Tankless Water Heater, Multi-Application hot water heater electric

This heater is NOT designed for a standard water heater tank. It can be used as a replacement for a standard electric hot water tank on the cold side only.

This will allow you to modulate the temperature of your water using a ball valve or some sort of control that opens and closes the flow going into the heater. What this control does is take off as much incoming water as it can so as not to overheat the coil. You can also use a Tstat to control this (the normal way is the T-Stat turns on and off).

This will allow you to modulate your water temperature up and down to keep it from getting too hot or too cold with little consequence of energy usage. We would only recommend this for applications that require lower temps such as washing cars, watering plants, showering, etc., not for cooking/drinking type uses.

The heater must be installed in an area where the ambient temperature is no more than 140 degrees F when the heater is running at its maximum output.


• Shortens your long hot showers

• Keeps your home comfortable in the winter

• Customizable temperature puttings

• Efficiently cuts down on HVAC costs by 50%
