Central heating innovation programme (Chip) (CP767)

LEAD AGENCY: Arun District Council
OTHER PARTNERS: C Mitten Plumbing and Heating
PROJECT SUMMARY: This project will provide innovative heating system enhancements to 10 homes where occupants are in fuel poverty.  This will involve the installation of a smart monitor, along with traditional Standard Thermostatic Radiator Valves (TRV) and smart TRVs to radiators. The project will assess the effectiveness of traditional standard TRVs against newer Smart TRVs in lowering heating costs and improve the heating in the home.

Smart TRVs allow every heating zone to be independently controlled up to six times per day.  These radiator controllers are sophisticated, having the ability to sense when a window is opened, and how long it takes for each room takes to reach the set parameter, allowing the Evohome controller to understand when to turn the heating on or off to maxi have been installed in each Smart TRV household to show how much energy is being used, helping work out the carbon footprint, and where energy and money can be saved.

Standard TRV by comparison is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.A crucial element to the project is education: occupants will be taught how to turn down / off TRVs allowing them to save energy, and shown how to use the smart monitor to understand their energy use.  Home Energy Visitors from Arun District Council visit people in fuel poverty, offering advice on energy saving measures, and will provide referrals for this project and monitor the outcome.

EVALUATION METHODOLOGY: Conduct interviews with a sample of households to capture behaviours and previous energy expenditure. Supplement household interviews with thermal data‐logging conducted in the living room and a less frequently used room with recognised calibrated stand‐alone devices, and residents will be encouraged to record energy meter readings periodically.  Gas usage will be logged in a sample of homes receiving each type of TRV.  Data can also be downloaded from the Efergy e2 smart monitor, which may be used for evaluation purposes.  Monitoring will be over 12 months, and will include a full winter heating period.
PROJECT OUTCOMES:
  • The programme will create data to improve understanding about the benefits of smart TRV installations against standard TRV’s in fuel poor households.
  • The programme will also encourage behaviour change and understanding as to the benefits of smart TRV technology in managing domestic energy consumption.
