Vian Heat Pump - C5 PLUS. 5kw Inverter Air Source Heat Pump

The Vian C5+ can operate down to -10 degrees, though efficiency will be questionable at this low temp. With its Full DC Inverter, this space-saving heat pump offers stepped power resulting in improved efficiency to ON/OFF systems. With a draw between 0.168 - 0.898kw and maximum output of 5.1kw, you will notice the saving on your heating costs, more so as the ambient air temperature starts to climb.


This Air Source Heat Pump requires 500mm clearance on the rear and sides minimum, and 2000mm on the front (fan) side.


Comes with power lead, drain hose and manual.


For supply only, you will need to source additional plumbing fittings to connect the unit to your hot tub, swim spa or pool, in addition to pipe lagging (insulation). 


For standard installation, this includes plumbing the heat pump close to the hot tub, swim spa or pool, within the recommended parameters. Supply and fitting all plumbing, lagging (insulation) and labour included, within our service area only.


If you are located outside our service area, or require a more complicated installation due to locating the heat pump further away for example, then please contact us.
