  15. 15. eTRV – In actionConclusions so far.For the month of February I have clearly saved a goodly amount of gas -probably around 20%. The reason for this is that I am able to turn the radiatorsdown using the timer capability in the evening period when we have a open fire inthe living room.I believe the eTRVs are much more responsive to room temperature changesand have much less hysteresis than the old mechanical TRVs. I had a similarissue with the thermostat on my hot water tank until I installed an electronicversion.I have found them more convenient for turning radiators off sporadically astemperatures increase as spring comes.Am I convinced they have benefits? Yes. Chris Gare
  16. 16. “The eTRV addresses a key issue for Higher Education establishments. It is well known that electrically heated halls of residences perform much better on energy consumption than wet heated halls. This is due to distribution losses and controllability. Students generally do not pay directly forenergy consumed so there is no incentive to limit their heating.Traditional radiator with TRV systems are set at the highest level on the first day of occupation and left that way all year. Electric panel heaters have for some time been offered with run-ontimers that provide background heating and a manual boost forwhen the conditions require it and the student is actually there. The eTRV replicates this and with the addition of its internal time clock allows for a night setback that further saves energy. The University of Bristol wishes to provide a comfortableenvironment at the lowest carbon impact and the combination of gas fired heating and the controllability afforded by the eTRV we hope proves to be a winning combination.” Chris Jones Sustainability Manager (Energy) University of Bristol
