This is the German engineered Hot Water Heat Pump from Stiebel Eltron. It features a 220-litre capacity with a design suitable for diverse Australian and New Zealand conditions. You have the flexibility of installing this unit indoors or outdoors depending on your home and, with its encased compressor you will enjoy its quiet operation. If you’re living in a cooler part of the country, you’ll still be able to enjoy this water heater, thanks to its active defrost function which can produce a hot water supply for households that experience outside temperatures as low as -5°C. This heater can also supply up to 360 litres of 40°C water (showering temperature), which is enough hot water to satisfy a medium-sized household. The WWK has an incredibly low amp usage, making it one of the most efficient water heaters on the market, helping you save water and energy.
