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

Co-efficient of Performance (COP)• EN14511 Standards – Normal measurement of heat

pump (compressor) only.

COP for Danfoss Ground Source Heat Pump 4.88B0/W35∆T 10K warm side excluding circ pumps

COP for Danfoss Air Source Heat Pump 4.47A7/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)

Seasonal Performance Factor (SPF)

Funding

• Direct Funding– £ 1500 for domestic user (Ground Source)– £ 900 for domestic user (Air Source)– £ Project funding for developers of

domestic dwellings

• Grant Funding– Low Carbon Building Programme Phase 2E– Scotland (CARES)

Funding – The Future

• Low Cost Energy Efficiency Loans– Current government proposal

• Renewable Heat Incentive– Proposed April 2011– Generate income from energy production!– Invest in solutions that deliver max kW/hr– No grants

Industry Standards

Heat Pump Summary

• All heating and hot water requirements

• Efficiencies - SPF not COP• Site Practicalities• Renewable, reliable, sustainable• Funding available
