The Lab Work – Electronic TRV vs TRV
Chalmor undertook testing, verified by the London Southbank University (LSBU), which shows the following:
■ eTRV+’s Patented Dual Sensor Technology provides market leading temperature control: Under laboratory conditions, room temperature fluctuated by a very minimal .5°C over a 1 hour period with eTRV+ smart radiator valve. Two separate competitor products were tested under the same conditions, both providing a far greater fluctuation of 4.5ºC within an hour.
■ Traditional TRVs: This was greater than a traditional TRV, which fluctuated by 2.5°C in a one hour period.
■ In the home: We also tested in a home situation, comparing eTRV+ with traditional TRVs over a one year period from February 2011 to February 2012. During the winter, gas consumption fell by over 30%, equating to an annual saving of over 20%.
