How efficienct is an Air Source Heat Pump (ASHP)?
Throughout the year air temperature fluctuates much more than ground temperature and consequently ASHP’s have to work harder during the winter months. However, the advances in ASHP’s in recent years has meant that the gap in efficiency between ground and air source heat pumps is much smaller. With less or even no ground works and the ability to install an ASHP on nearly any property, they are the cheaper easier option.
