7GD21E-3 Domestic Hot Water

Description

The new “Performance Plus” commercial range of domestic heat pump water heaters  provide  an  energy  efficient,  low  carbon  means  of extracting free heat from the ambient air  for  the purposes of heating and maintaining the potable hot water requirements for residential and commercial applications. Using patented single pass technology 60C water is delivered directly to the top of the hot water cylinder and unlike many systems can be retrofitted to most existing systems without cylinder replacement.
 
The heat pumps use  a  zero  ODP  (Ozone  Depletion Potential)  and  low GWP (Global Warming Potential) refrigerant (R-410A) that complies with all current NZ/AU legislation.
 
The condensers are built from stainless steel compact brazed plate.
