Upgrade to a more efficient Hot Water system
The Rinnai Enviroflo B Series Electric Heat Pump operates by utilising a heat exchange system that absorbs the heat from the surrounding air and uses it to heat your water. The innovative controller works to maximise hot water availability while using up to 70% less energy, compared to a standard electric storage tank.
Combine this with the included Wi-Fi enabled Timer Function allowing you to utilise solar PV usage, and watch your energy consumption drop. These tanks have been designed and tested to operate with water pressures up to 850kPa. Best of all, they are lighter in weight to aid quick and safe installation whilst having a minimal impact on the environment.
