Exploiting constant underground temperatures throughout the year, GSHP systems use a buried ground loop to transfer this heat from the ground into buildings to supply heating and hot water, providing one of the most energy-efficient ways of heating buildings.
Technology comparison
The graph below shows the grams of CO2 produced per kWh from eight different heat generating technologies. Electricity has long been the highest producer of CO2 in comparison with traditional heating methods such as gas and oil boilers, however when electricity is used to run GSHP the outcome is very different, with over four times less emissions produced.
Even when comparing GSHP with the latest condensing gas boilers, the graph still shows it is possible to achieve CO2 savings in excess of 50%.
Different technologies' CO2 output in grams per kWh
- The graph shows the grams of CO2 produced per kWh from six different heat generating technologies based on average operating conditions. (Data available to BS EN 14511 conditions on request). This clearly shows the emissions reduction from using heat pump technologies.
- Figures based on heating water to 45°C from an average source temperature. Emissions will alter dependent on source and load temperatures.
