Air and Ground Source Heat Pumps

1. Air and Ground Source Heat Pumps A presentation by Alan Westlake – Programme Manager (RHA) and Jeremy Pallant – Director Greensave

2. The Problem • 1200 properties with no mains gas. Using open fires, solid fuel central heating or night storage heaters. • Rural area – obtaining regular fuel delivery. • Decent homes failure. • Expensive Options – oil, LPG or electric wet systems. • Fuel poverty (17% of residents)

3. The Solution • Air source heat pumps. • Ground source heat pumps. • Biomass boilers. • Up to 400% efficient. • With up to 50% grant funding, installation is comparable with oil fired central heating.

4. Ground Source Heat Pumps • Uses geothermal and solar energy to provide heat source through pump. • Able to be retro-fitted and connected to existing systems* • Can be used with new installations. • Used in conjunction with “north wall sensors” to maximise efficiency. • * After power flushing and pressurising the existing system

5. Air Source Heat Pumps • Extract energy from the surrounding air. • Able to be retro-fitted and connected to existing systems* • Can be used with new installations. • Used in conjunction with “north wall sensors” to maximise efficiency. • * After power flushing and pressurising the existing system

6. Background • Residents currently given choice for replacement heating, un-predictable oil and LPG prices. • Pre-installation surveys collect information on current fuel costs and heating habits. • Properties inspected for installation practicalities. • Residents briefed on potential of heat pump and efficiencies.

7. Objectives • To provide efficient forms of heating. • To provide low running costs to residents and assist in understanding of appliance. • To provide “comfortable” and convenient heat. • Prevention of progressive fuel poverty. • Reduction of carbon emissions (CERT)

8. Scope • Ground and Air Source Heat Pumps: • High efficiency. • Compatible with standard radiator systems. • Flow temperatures of up to 65°C. • Heat and hot water. • Low maintenance. • 20 year life cycle. • Integral controls set at commission stage.

9. Constraints • Cost • Initial outlay can seem high. • Funding • Available funding must be sought and used. E.g. Low Carbon buildings Programme (Phase 2) • Site • Practicality of site. • Resident Perspective • Residents have to be on side with technology to get the maximum from the system.

10. Perceptions • Witch craft and black magic! • Expensive on electricity! • How can it work? • It’s not a boiler!

11. Resources • Greensave Solutions Ltd. • Accredited Worcester Bosch ASHP & GSHP installers. • Accredited Heat King ASHP installers • 30 years drilling experience. • 3 installation teams. • Apollo Group Ltd. • Environmentally aware • Extensive supply chain

12. Delivery of the solution • What – Renewable forms of energy: Air & ground source heat pumps • How – installation of heat pumps. • Why – to reduce running cost, carbon emissions and to lower management costs. • Where – rurally located housing stock. • When – from October 2008 • Who – Roddons, Apollo & Greensave

13. Benefits • To Residents To the Environment • Low cost ∙Reduced Carbon Emissions • No fuel delivery • Constant ambient temperature • To Roddons • No oil tanks (reduce capital outlay) • Reduction of fuel poverty • Added Green credentials • Reduced servicing and no annual CP12 • To Greensave • Opportunity to provide renewable forms of energy for high profile client. • To Apollo • Support alternative technology
