Isn’t Heat Pump technology new and untested?
The technology is actually very old. The Heat Pump was imagined by Lord Kelvin in 1852 and developed by Peter Ritter von Rittinger in 1855. Each year, about 80,000 units are installed in the USA and 27,000 in Sweden. In the UK there are well over a 1000 Heat Pumps installed and their popularity with home builders continues to grow rapidly as people search for a renewable solution to both their high heating and hot water bills.
