Would you like to install a heat pump in your home? The Heat Pump Association, (your Editor is an Honorary Life Member), has, in conjunction with other Trade Associations, produced a most useful guide: View the Guide (PDF)
Heat pumps can provide high-efficiency, low-carbon heat for dwellings. Their performance is optimised if low-temperature heat emitters are used for heat distribution in the house, so this guide aims to help you select an emitter type and operating temperature which will result in high efficiency and low running costs.
The guide uses a Temperature Star Rating to indicate how efficient the proposed system is likely to be. More efficient systems are given a higher number of stars. The maximum is 6 stars. More stars are given when lower heat emitter temperatures are used because the heat pump is able to operate more efficiently.
