Product Details

- Connection to mains pressure hot water cylinders
- NZ geographical zones 1 and 2 only, these being the North Island, and Nelson & Bays ONLY
While the Rinnai Hot Water Heat Pump will operate at temperatures between -7 °C to 45 °C, output and efficiency will reduce at lower temperatures. For example:
- With an outside air temperature of 20 °C, the heat pump delivers 3 kW of heat output for every 1 kW used, making it 300% efficient
- With and outside air temperature of 10 °C, the heat pump delivers 2.6 kW of heat output for every 1 kW used, making it 200% efficient
Not suitable as a spa or swimming pool heater.
Not suitable for dense housing areas as the operating noise, especially at night, could be disruptive for neighbours. In Australia timers have been used to mitigate this problem, however the homeowner needs to be aware that in some instances they may not have hot water when they need it.
Water quality
Not suitable for certain water chemistries. Examples of water quality issues where the water may need to be treated prior to using a Rinnai Hot Water Heat Pump are:
- Hard water areas such as in Wanganui
- Aggressive water areas such as in Christchurch
- Bore water areas where the water may be hard and/or aggressive
Geothermal hot spots
The Rinnai Hot Water Heat Pump is not warranted against corrosion in geothermal hotspot areas such as Rotorua, where high levels of sulphur dioxide are present in the atmosphere.
Distance between the heat pump and the storage tank
If the heat pump and cylinder are more than 5 m apart an R5043 adjustable flow restrictor must be purchased as a separate item to complete installation.
Refer to p. 16 of the operation and installation guide (in the downloads) for pipe diameter and maximum pipe length, including the return.
