Consider this: would you choose an ordinary cooling and heating unit for your home or business that will eat on your electricity usage and only provide you with the desired temperature after a waiting period, or would you invest in a unit that will work on the lowest power use and have immediate heating or cooling effect? Not that big of a mind stump, is it? Well the answer will be heat pumps. Heat pumps are not new technology, as a few of our everyday appliances make use of them, such as fridges, freezers and some air-conditioners.
