The need to decarbonise heating demands technologies that go far beyond the best performance associated with fossil fuel systems, but without the cost, complexity and constraints associated with many renewable energy systems. The high temperature air source heatpump is just such a solution. It is compact, doesn’t need fuel deliveries or constant attendance and has minimal environmental impact.

The air source heatpump development has been integrated with the district heating design. Through extensive modelling, it has been demonstrated that the high temperature air source heatpump can deliver effective and affordable heating to existing social housing. The result will be a 53% drop in carbon footprint, dropping even further as the grid decarbonises.

The impact will be a generation of cleaner, lower cost heating for householders.

The Neatpump air source heatpump is part of an affordable, low carbon heating solution that has been developed by Star Renewable Energy in collaboration with partner organisations from the housing sector, installers and engineering consultants. As an integrated solution it has great potential for deployment in a wide range of applications.

Star contributionFollowing successes with water source heatpumps at 90°C, the team also brought skills in hot gas defrost to create a heat pump like no other. Temperature and efficiency barriers are broken with this design. In-house controls enable maximum seasonal efficiency and remote monitoring.

GHA contributionAs one of the largest social landlords in the UK, GHA drive for lower cost, lower carbon solutions for their customers. They were able to assemble a team and drive the initial assessment and will lead the deployment project.

Integrated Heatpump Solutions

1Variable speed fans for lowest noise and power consumption

8Web enabled controls interface for maximum efficiency control, automatic defrost and remote monitoring

7Variable speed, semi-hermetic compressor for maximum capacity control, efficiency and leak-tightness

5Heated baseplate for frost protection

6Desuperheater, condenser and sub-cooler for maximum efficiency

4Flow and return integrated with auxiliary heat but 80% of heat from heatpump

2Low pressure receiver for lowest refrigerant charge

34-way valve for hot gas defrost giving maximum uptime and lowest defrost cost

WSP Parsons Brinckerhoff contributionEngineering consultants WSP Parsons Brinckerhoff recognised from the outset that utilising low district heating temperatures would be key to success. Their system modelling expertise developed a fully integrated system design, not only to maximise heatpump efficiency but also to deliver effective heating within the practical constraints of retrofitting to existing housing stock.
