Air-Water heat pumps are at the centre of our solutions as they are the most cost efficient way to heat water today. They can heat central heating, pools and Air Conditioning at a fraction of the cost of traditional methods. In fact, most modern Air Conditioning systems use heat pumps for the heating mode making them a great cheap way to heat a home in winter months. Our AQ and Aquatherma solutions all use heat-pumps. To some it may seem imaginable that heat from the air outside could be used to make water heat to 55 degrees for use in showers etc. We found a very helpful short video on YouTube to explain.
