Built-in Electric Strip Heat (AUX EL)

Electric Resistance Heat (optional) –NHP NorthStar Series heat pumps may be ordered with optional electric

resistance heat. This feature is installed for various reasons. Most commonly, particularly in northern climates

where extremely low temperatures are found, geothermal heat pumps are often intentionally undersized for the

coldest days of the year. In situations where the heat pump is undersized, an Electro Industries KN series

auxiliary electric heating unit (AUX EL) can be built into the heat pump to meet your additional heating

demands during these extremely cold days. Additionally, the AUX EL feature can be utilized for emergency

heat if your heat pump should malfunction for any reason.

Although these units utilize 100% efficient electric energy, AUX EL can never approach the energy efficiency

of your NHP geothermal heat pump alone. For this reason, your NHP Northstar Series heat pump will attempt

to utilize geothermal heating as much as possible. When heating demands reach a level where geothermal

heating cannot “keep up”, the exclusive NHP EZGEO control will add in just enough resistance heating to meet

your heating demands. Here, the duct temperature target point can be adjusted to the preference of the

homeowner. This will be discussed later in this manual.

If your NHP heat pump did not come from the factory with AUX EL installed, AUX EL kits in various sizes are

available from NHP. The addition of one of these kits should only be performed by trained professionals who

are familiar with this product.

Not all of the AUX EL units can be paired with every NHP heat pump. Please refer to this chart to determine

which resistance heat unit can be used with your heat pump.
