Energy savings from TRVs (2018)

A series of tests were carried out to establish the energy saving benefits of Thermostatic Radiator Valves (TRVs). The tests were carried out independently by the University of Salford and commissioned by BEAMA Heating Controls, the UK association for manufacturers of controls used in heating and hot water systems and for wider control of the internal environment of residential buildings. The tests were also carried out in close co-operation with BRE, who manage the energy performance calculation methodology, SAP, on behalf of the UK Government. The tests were set up to measure the overheating that would occur in a residential building over the course of a heating season if TRVs were not present. The resulting energy savings from heating were compared.
