Heat pump technology is one of the cutting edge technologies when it comes to renewable energy water heating products. Even though this technology has been used in South Africa for heating water for many decades, the recent increase in international demand has brought the component costs down, making the product affordable for the residential and commercial users. Using the refrigeration cycle to extract energy from the surrounding air (indirectly using solar energy) it can provide you with up to 60ºC hot water day or night, winter or summer at a quarter of the cost of electrical geyser element heating.
