Comparison of two electric heating solutions for a tower block (CP1138)

This project installed two different combinations of electric heating systems to 20 x 2-bedroom flats in a tower block in Walsall, West Midlands, also comparing them against a control group who did not receive new heating:

1. Enviroheat EconoRads and EconoCylinder, controlled by Honeywell room stats and Switchee on a flat-rate tariff – 10 flats (4 flats switched to control by Honeywell Evohome),
2. Elnur storage heaters, and Switchee, controlled by VCharge on an Economy 10 tariff (no change of immersion tank) – 10 flats,
3. Controls: original electric storage heaters and immersion cylinder, with Switchee fitted for monitoring purposes only – 5 flats.
