The project involves the installation and monitoring of 5kW Mitsubishi Ecodan Hybrid Air Source Heat Pumps interfaced with existing oil boilers (Hybrid ASHP) into 10 properties. The Hybrid ASHP is designed to work with the existing oil-fired boiler currently used as the main source of space and water heating. The hybrid ASHP works in combination with the existing boiler, operating when the outside air temperature is above a pre-set level. Below this level the existing oil-fired boiler will heat the property to ensure that the ASHP operates at the optimum efficiency.

This project part-funded the installation of a Gas Absorption Heat Pump (GAHP) into a sheltered housing scheme that was undergoing major refurbishment. Project partners Colchester Borough Homes had already installed one GAHP into a sheltered housing scheme with positive feedback. However, they wanted more information about the efficiency and cost effectiveness of the GAHP.

This project retrofitted existing night storage heaters with VCharge Dynamos in a tower block situated in the west end of Newcastle Upon Tyne. Despite the tower block being previously insulated and the windows being replaced, residents continued to note that they were unable to keep warm at a reasonable cost. The VCharge Dynamo aims to increase comfort and reduce energy use by charging the storage heaters by an amount proportionate to the households predicted preferences, taking into account the internal temperature, previous consumption patterns and external temperatures to determine how much charge is required. A total of 26 properties received VCharge Dynamos and of these 14 were monitored.

This project will installed SunGain Battery Bank (SBB) energy storage technology in 35 homes alongside Solar existing PV systems for the benefit of fuel poor and vulnerable households off the Gas Grid in Thurrock. The project will assess the potential of enhancing the efficiency of PV technology.

The project was led by Nottingham Energy Partnership (NEP).

This project focused on the installation and evaluation of measures or combinations of measures in homes at risk of fuel poverty. There was a mix of innovative and more well-established technologies installed in the properties. WDH’s standard heating replacement programme focuses on standard energy efficiency measures and typical gas and electricity heating systems. These measures have been available through ECO and its previous iterations.

This project installed a hybrid combination of a Mitsubishi air-source heat pump (ASHP) with novel Solar Angel PV-T (PV and thermal) solar panels in 21 homes, to provide a “whole house” approach, in rural properties not connected to mains gas in Norton, Kent and Iden, East Sussex.

This project used airtightness tests to identify sources of uncontrolled ventilation and cold spots in poor energy efficiency (SAP bands D G) properties in a rural area of Wales, highly exposed to sea winds, often solid walled or other hard to treat (HTT) construction, and most not being served by mains gas. Results of the tests highlighted appropriate airtightness measures which could be installed to address and reduce uncontrolled air exchange, to provide energy savings and improved comfort to the residents, vulnerable to fuel poverty.

No fines concrete houses are houses that have walls constructed from in situ cast concrete that does not contain the fine aggregate that is usually mixed within the concrete. This means that the larger aggregate (gravel of 10 20mm in size) is bound by a cement slurry coating. As such, connected voids are found throughout the walls. The result of this is that these house types do not behave like other solid wall properties in relation to heat retention, air tightness and resistance to moisture
