Heat Pumps and carbon emissions

Heat pumps are a terribly important technology, but we run the risk of being indiscriminate in their use. Not every heat application is environmentally suitable to operate with a heat pump. We have to choose the best horse for each course when it comes to microgeneration and renewable energy.

A heat pump works by exploiting ground or air temperature differentials to make the use of electricity more efficient, when electricity is turned to heat. This can be very effective in saving carbon emissions in homes that are off the gas grid network.  Typically heat pumps can make the electricity twice or three times more efficient. Continue reading
