Air-source heat pumps, solar PVT and heat recovery in off-gas homes (CP752)

LEAD AGENCY: AmicusHorizon
OTHER PARTNERS: Energise Sussex Coast
PROJECT SUMMARY: The project aims to evaluate a ‘whole-house’ approach to improving the energy efficiency of rural off-gas homes Kent and East Sussex. It will install air-source heat pumps (ASHP) and combined solar PV/thermal (PV-T) in 21 homes, and a heat pump with a Heat Recovery Unit in a further 4 homes. The project will determine the savings expected from these technologies in fuel, poor households, and the impact on the SAP ratings on these properties from the installation of the proposed technologies.

Energise Sussex Coast is AmicusHorizon’s trusted energy advice partner in Sussex: they will provide tenants with expert in-home advice on the control of their new renewable energy heating systems. They’ll also provide energy tariff switching and more general energy and water efficiency advice.

EVALUATION METHODOLOGY: NEA will conduct interviews with a sample of households receiving the technologies to capture behaviours and previous energy expenditure, as well as the residents understanding and perception of the technology.

Household interviews will be supplemented by a comprehensive data monitoring system comprising of electrical logging to quantify the electrical energy produced by the PV-T panels, and overall electricity use by the household. Heat meters will be used to determine the thermal output from the PV-T panels, and the heat supplied to the domestic hot water (DHW) tank. Heat and electricity generation meters are installed to capture this. Thermal data logging will be conducted throughout the project in the property using standalone devices to determine thermal levels in the property. Monitoring will be for 12 months, and will include a full winter heating period.

PROJECT OUTCOMES:
  • This project will provide data to determine the effectiveness of using these technologies in off gas areas as an alternative to traditionally installed systems.
  • The project will provide evidence as to the appropriateness of these systems for other areas and partners, and will determine the energy saving benefits and acceptability of hybrid ASHP / solar PVT in fuel-poor communities.

Extended TIF programme, results due summer 2018
Monitoring and evaluation of this programme will continue during the winter of 2017/2018, doing so will enhance the quality of data and enable a comprehensive evaluation to take place.
