ERHP-SU Series | Residential (Circulating) Heat Pumps

Development of the Enerflow ERHP-SU series heat pumps started in 2008 already.  These units are still in operation.  The most popular units in the range have all been tested at the SABS for energy efficiency and all of them passed with flying colours.

Circulating Heat Pumps

This series employs state of the art technology that ensures the efficient generation of environmentally friendly hot water.  This range is capable of generating hot water without the use of auxiliary heating from electrical elements.

State of the art technology includes an electronically controlled expansion valve (EEV).  The intelligent control algorithms ensure that the internal flow rate of the refrigerant is optimised via the EEV to deliver unmatched efficiency and reliability even in low winter ambient temperatures.

The popular models in this series are available in both powder-coated and durable, UV-stabilised polymer casings (recommended for coastal regions).  The critical structural components of the units are firstly treated by an electrophoresis process before the final weather coating is done.  This ensures that the units are more resistant to corrosion than just plain powder coating. The structural components of the polymer casing units are hot-dip-galvanised to ensure better corrosion resistance.
