Ground Source Heat
Heat and Energy Saving consultation; GSHPA will work on its development and implementation.
The Ground Source Heat Pump Association (GSHPA) welcomes today’s Heat and Energy Saving Strategy (HES) consultation where the Government sets out a framework for reducing emissions from existing buildings. This includes encouraging technologies such as renewable heat that is a vital element in realising the Government’s over 80% carbon reduction in buildings target by 2050.
Heat pumps are the main existing low carbon heating solution; a well designed and installed Ground Source Heat Pump (GSHP) system offers at least a 33% carbon dioxide and 38% financial saving as compared to a gas condensing boiler heating system (see below for figures). The other low carbon solutions, such as biomass and solar thermal, do not currently have the capacity to meet much more than 15% of the UK’s heating requirements. The GSHPA believe that ground source technologies should hold an even higher profile in the governments plans to reduce carbon emissions.
The GSHPA also welcomes the emphasis placed on communities and district heating in this consultation and notes that GSHP systems can supply a full range of heating requirements from domestic properties, schools, hospitals, factories and large district heating networks.
GSHPA Chairman, Karl Drage says “Given the Government’s backing for growth of the sustainable energy markets, the GSHPA looks forward to working closely with Government and industry to reduce carbon emissions, minimise fuel poverty and create new jobs in green technologies.”
Carbon and Financial Savings from GSHP systems
• GSHP @ 350% efficiency and 0.54 kgCO2/kWh electricity = 0.15 kgCO2/kWh
• Gas Condensing @ 80% eff.* and 0.185 kgCO2/kWh gas = 0.23 kgCO2/kWh
In this case, GSHP is 33% CO2 improvement and 38% running cost saving
* Based on 3.3 p/kWh gas and 8.9 p/kWh electricity from BSRIA and carbon figures from DEFRA. 80% gas condensing system efficiency is based on currently ongoing EST field trials. This efficiency figure is yet to be published and might be subject to change. However, our understanding is that it is far more accurate than stated boiler efficiency of 91%. Heat pump system efficiency of 350% equates to a realistically GSHP achievable CoP of 3.5.
Please note that these savings will considerably improve as the grid is decarbonised from its current 0.54 kgCO2/kWh to a significantly lower figure by 2020.
