Steve Brown Development Director for Envirotec Ltd explains the theory behind how heat pumps work:  Heat pumps use the same technology as is used in a refrigerator, exploiting the temperature difference between the refrigerant gas and its surroundings. Both rely on three key facts.  Heat will move down a ‘temperature gradient’ from a higher temperature to a lower temperature. When a liquid changes to a gas, heat is extracted from the surrounding to provide the energy for this change (e.g. boiling water to steam).Refrigerant gases have a boiling point well below 0°C. For example the R410A refrigerant ...
