Heat Emitter Guide October 2011

11 November 2011

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.
