The project comprises the replacement of the heating and hot water systems of two residential sheltered blocks whose residents are over 55 years of age. The main block comprises 41 flats; the second and smaller block to the rear of the main block comprises 15 flats.

Ongo Homes installed three different types of innovative full heating systems into 30 properties from their social housing stock. Existing heating was removed and replaced with one of the three technologies: 14 Logicor infrared radiator systems, 10 Daikin Altherma hybrid heat pumps and six Sunamp heat batteries.

External wall insulation (EWI) is an established technology that improves heat retention and energy efficiency. In essence, EWI provides an external jacket to a park home that significantly enhances thermal efficiency. This should improve performance of existing building fabric, ensuring a warmer living space in winter months, and cooler living space in the summer months. A further stated benefit of EWI is improved sound proofing, which can further enhance the living experience of householders.

This project was delivered by YES Energy Solutions in collaboration with North Lincolnshire Council.

After the successful delivery of a project that replaced electric storage heaters with hybrid heat pumps Home Group were invited to run an additional hybrid heat pump project. This project replaced gas boilers that were due for renewal with Daikin Altherma Hybrid heat pumps. The hybrid system combines an air to water heat pump alongside a condensing combination gas boiler to provide heating and hot water. The system can automatically select the most cost effective and efficient heating mode based on external and internal temperatures, the space heating and hot water demand, and the current cost of gas and electricity.

This project used Q-Bot’s novel “SprayBot” to install a 12.5cm thick layer of Elastospray® 1629/1 foam insulation to the under-side of suspended timber ground floors in properties in the London Borough of Camden (LBC).

This project was delivered by South Holland District Council. It mirrored a similar project with the same partner to compare three other smart heating controls in other council owned properties1. Each project was recommended by the funders to involve installation of 45 to 60 heating controls of three types for comparison. The two projects were on too large a scale to be combined into 1 project report, but the methodologies were comparable so comparison is possible.

Ceredigion comprises of a series of isolated rural communities, with 82.4% of homes not connected to mains gas – the highest number of off-gas properties in Wales. Tregaron, the area targeted for the project, falls within the top 30% most deprived, and the rural areas around it fall within the top 10%, in terms of access to services.

This project was led by Arun District Council in West Sussex. It involved the installation of Honeywell evohome intelligent heating controls and traditional thermostatic radiator valves (TRVs) in homes where residents previously had no (or old, basic) TRVs. Energy monitors were also installed to help residents understand electricity use.
