Whole house innovation project (Whip) (CP766)

LEAD AGENCY: Together Housing Group
PROJECT SUMMARY:

This project pilots four technologies:

  1. Chop Cloc – A time-based heating device that sits between the thermostat and the boiler, allowing users to set how much “off “ time there is on the heating system every hour, without impacting on comfort.
  2. The Energy Saver – a non-corrosive heating system additive which changes the way heat is transferred from the boiler heat exchanger to make the system water warmer so using less energy to reheat it.
  3. Switchee – a smart-connected thermostat (developed recently with the social housing sector as its target market), an intelligent heating control with wireless monitoring functionality, to track changes in consumption remotely. Switchee also senses and predicts a tenant’s weekly routine, turns heating off when no-one is home, and prompts users to reduce room temperatures. It can measure humidity and trigger low-temperature alarms.
  4. Tadpole – the Tadpole is a device fitted onto your heating system  which removes the air and the dissolved oxygen, which causes corrosion, from the heating system water leading to higher operating efficiency of the heating system. Evaluation method: Conduct interviews with a sample of households to capture behaviours and previous energy expenditure. Supplement household interviews with thermal data-logging conducted in living and main bedrooms with recognised calibrated standalone devices, and manual energy meter readings will be requested from householders. Data produced by Switchee will be used for monitoring in all homes receiving a device. Monitoring will be for 12 months, and must include a full winter heating period.
  5. Technology trialled: Chop Cloc, The Energy Saver, Switchee, Tadpole
  6. Number of households helped: 252
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 living and main bedrooms with recognised calibrated standalone devices, and manual energy meter readings will be requested from householders. A sample of homes receiving Chop Cloc will have a heat/flow meter fitted to the boiler; a sample of those receiving The Energy Saver will have thermal imaging of the radiator surfaces before and after addition of the additive, to ascertain any changes. Data produced by Switchee will be used for monitoring in all homes receiving the device. Monitoring will be for 12 months, and must include a full winter heating period.

PROJECT OUTCOMES:
  • Testing these products on a range of properties will give us a truer indication of the amount of energy and money that can be saved by installing them in a property. Chop Cloc estimate savings of 18% but this hasn’t been tested in as wide a domestic setting
  • Previous applications of The Energy Saver have been successful in commercial environments, but testing in a domestic environment is required to show the impact of the product, which could form part of the gas maintenance regime. Target savings for this product are 20% of heating costs. These claimed energy savings will be evaluated in this project.
  • Switchee is a brand new product, and this testing will be a major factor in bringing this purpose-designed technology to market, assessing its benefits in terms of usability, comfort and financial savings.
