Comparing advanced heating systems in Wakefield (CP758)

Lead agency WDH (Wakefield and District Housing)
Other partners Wakefield Metropolitan District Council
Project summary

This project will provide the opportunity to trial, monitor and evaluate a number of different heating systems in vulnerable and fuel poor social and private households across the Wakefield District.  It is led by WDH (Wakefield and District Housing) in partnership with Wakefield Metropolitan District Council (WMDC).  The project will inform future retrofit decisions by the social landlord and a programme for private sector housing being developed by the District Council.The performance of five advanced heating technologies will be compared with traditional gas boilers in semi-detached properties in both social and private rented tenure.  The new technologies include a gas boiler with flue gas heat recovery, an Air Source Heat Pump (ASHP) with a solar PV system, a hybrid system comprising an ASHP and gas boiler, a solar thermal system with a gas boiler, infra-red heating panels and a modern storage heater system.  The study will compare performance based on a sample of 6 households for each technology.   It will also consider capital cost, lifecycle cost, tenant perception (warmth/comfort and controls), temperature and humidity, energy costs and consumption as well as the improvement to the building’s EPC/SAP rating.

Evaluation Methodology  

Interviews will be conducted with households to collect patterns of behaviour and previous energy expenditure, as well as thermal comfort and experiences of their old heating systems.  Thermal loggers will monitor the temperature in the living room and main bedroom.  The incoming electricity supply to the ASHP and the generation from the solar PV system will both be logged.  Heat meters will also be fitted to record the thermal output from the ASHP and solar thermal and gas boiler systems.  A current clamp will monitor the electric heat load of the infra-red panels.  Households with installations that include a gas boiler will have a gas meter logger.

Project Outcomes

  • The project will compare the performance of five different advanced heating systems against a traditional gas boiler system
  • It will take a cross-tenure, community-based approach and therefore unlock something that wouldn’t have happened otherwise.
  • The results will support the creation of an ‘advanced retrofit standard’ at WDH to inform future investment programmes for its 31,000 properties.
  • Findings will also inform Wakefield Metropolitan District Council’s private sector home energy efficiency improvement programme and the Wakefield Affordable Warmth Action Plan.
  • Case studies will be prepared and disseminated via the council and social landlord while best practice will be shared at seminars and events such as NEA Fuel Poverty Forums.
