Seasonal primary energy efficiency ratio
Seasonal primary energy efficiency ratio (SPEER) is: ‘…an emerging rating figure reflecting the use of primary energy for all types of heat pump, fossil fuel boiler and gas-driven cogeneration technologies, as well as hybrid systems where solar heating or a heat pump is backed up with electric heating or a fossil fuel boiler. Energy labelling with the SPEER will be mandatory from 2015 under the Energy Labelling Directive. Testing and rating will be in accordance with EN 14825, as for SCOP (seasonal coefficient of performance).’
