Renewable energy sources How they work and what they deliver Part 3: Electrically driven heat pumps
December 1, 2014 - BRE

Electrically driven heat pumps are devices that may be used to generate heat for domestic hot water (DHW) and space heating. They achieve this by extracting heat from environmental sources such as the air or the ground. The heat is transferred to a refrigerant circuit where compression raises the...
