2. Agenda Introduction to heat pump technology Space Heating Hot Water Production Efficiency Practicalities Project funding Industry Standards Summary Q&A

3. Solar Energy Source

4. Heat Pump Process

5. Space Heating Distribution Temperature Efficiency Underfloor Heating Low Temperature Radiators Oversized Radiators

6. Hot Water Production Producing hot water reduces efficiency To maintain good efficiency… Patented Danfoss TWS technology provides highest efficiency and fastest recovery 52C hot water with automatic legionella cycle Standard water tanks will significantly reduce efficiency

7. Co-efficient of Performance (COP) EN14511 Standards – Normal measurement of heat pump (compressor) only. COP for Danfoss Ground Source Heat Pump 4.88 B0/W35∆T 10K warm side excluding circ pumps COP for Danfoss Air Source Heat Pump 4.47 A7/W35 ∆T 10K warm side excluding circ pumps Other components that will affect efficiency Hot water volume and temperature Brine circulation pump Hot water circulation pump Heating circulation pump Additional heat (Immersion heaters)

8. Seasonal Performance Factor (SPF)
