How can heat pumps be more than 100 efficient?
How can heat pumps be more than 100 efficient? By contrast, heat pumps seemingly undertake the impossible: you get more heating out than the energy you put in. This is possible because we are using energy to move heat – rather than converting the energy directly to heat. As a result the apparent efficiency in […]
