Trust the Energy Saving Trust Phase 2 Report

Good news for all heat pump suppliers, designers and installers the Energy Savings Trust has published its Phase 2 report the summary (in part) as below, reading between the lines they have concluded that a correctly designed and installed heat pump installed in the UK can provide significant benefits to the end user, this highlights three main issues:

1, A correctly installed system can offer all the heating required in a very efficient manner into a suitably insulated domestic property  (this is not new news but at least its been proved)

2 A poorly installed system is neither efficient, nor is it likely to offer comfort conditions

3 The MCS rules should assist in ensuring that all designs are correct prior to install, this to me is the most critical thing, if the original design is right the end user should save/earn money and have comfortable internal conditions

Summary of report as follows

  • Most in-depth study of its kind shows improved heat pump performance
  • Properly installed systems to highest standards key to heat pump success
  • Study launched as new Government incentive kicks in
  • In the right home air source heat pump users could earn around £1,350 a year and ground source heat pump users could earn around £3,000 a year in combined savings and income (Inc RHI in the first 7 years)

A new study from the Energy Saving Trust has found that the performance and efficiency of heat pumps has improved following recommendations to design, installation and operation.

Technical data obtained from an in-depth study of heat pumps at sites across the UK has found that well-installed and operated heat pumps perform to a very high standard in UK homes.

According to the Energy Saving Trust, homes best suited for heat pump installations could expect to earn savings and income of around £1,350 a year on air source heat pumps and around £3,000 a year on ground source heat pumps. (as per the previous RHI blog T&C’s will apply)

This follows the Renewable Heat Incentive (RHI) announcement by the Department of Energy and Climate Change (DECC) in July, which revealed householders could receive payments of hundreds of pounds a year for heat generated by renewable heat technologies, such as heat pumps.

The success of the heat pumps’ performance during the study was underpinned by the experience of the users. Eighty per cent were satisfied with their heat pump’s performance, while over three quarters (77 per cent) would recommend a heat pump to a friend, mainly because of its efficiency and running costs of the system.

The results build upon Phase 1 of the research, released by the Energy Saving Trust in 2010, which identified recommendations for the industry and end-users to achieve better performance from the technology. The results from Phase 1 showed wide variation, with the best-performing systems being those that were deemed to be properly designed and installed. The latest study, conducted between 2010 and 2013, investigated these variations in performance, with interventions carried out to achieve improved performance from the heat pump installations. Overall 20 of the 32 heat pumps undergoing interventions between Phase 1 and this study achieved improvements in performance with the remainder achieving similar or slightly lower performance.

Jaryn Bradford, Senior Technical Manager at the Energy Saving Trust, said, “Based upon the results of the study, we are convinced that heat pumps can play a significant role in providing an effective heating solution for homes and reducing carbon emissions.
