Energy Saving Trust Heat Pump Report
The Energy Saving Trust carried out a field study to monitor the performance of residential heat pumps between 2008 and 2013.
The Government has committed to reduce greenhouse gas emissions by 34% by 2020 to meet targets.
The Energy Saving Trust (EST) have performed heat pump field trials to ensure that customers choose the correct technology to heat their homes by showing unbiased, accurate performance information.
What happened in Phase 1?
In the time between spring 2009 and spring 2010, the EST monitored 83 heat pumps nationally to identify how UK homes perform over a year. The EST discovered factors that could affect the performance, including:
• System sizing
• Type of heat source/sink
• Building efficiency
• User behavior
• Heating patterns and average internal temperatures
• Installation practices
As a result of the Phase 1 Report, the technology, standards, supply chain and installer knowledge and practice evolved and improved.
What happened in Phase 2?
Phase 2 was developed to identify the causes of the varying performances of heat pumps.
From the results of Phase 1, the MCS installer standards were improved and used to set new standards for Phase 2 trials. 32 sites from Phase 1 trials (sites showed the worst performance) were amended according to the new MCS standards where applicable, thus would show enhanced operating performance in those sites and why.
To measure the results, the EST created a scale to show the amendments made to compare with Phase 1 trials. Also, 6 sites that were included in the Phase 1 trials were not amended to act as control sites (no intervention).
• Major Intervention
• Medium Intervention
• Minor Intervention
• No Intervention
After improvements made, Phase 2 trials started from Spring 2011 to Spring 2013 and new technology was used to capture more accurate results.
The results of Phase 2, compared with Phase 1 trials, shows significant improvements to heat pumps with major or medium interventions showing improvements can be made to increase efficiencies.
Heat pumps sold today are expected to produce much higher efficiency rates. Please contact email@example.com to find out more on Air Sourced Heat Pump efficiencies.
