TRV is A-rated for energy efficiency

摘要

The Drayton TRV4 has received an A-rating for energy efficiency under a new labelling scheme for thermostatic radiator valves (TRVs). The rating is based on how quickly a TRV reacts to changes in room temperature, how effectively it maintains stable room temperatures, and how it performs after changes in water temperature and system pressure.Drayton's TRV4 achieved the highest energy efficiency ratingthanks to its sensitive liquid-filled chrome head, which reacts swiftly to temperature changes to minimise energy use.
