The Energy Saving Trust (EST) is calling on heat pump installers to improve their installation techniques following the largest ever UK field trial of the technology…for full report CLICK HERE
The trial, which studied heat pumps at 83 sites – 54 ground source and 29 air source – began in early 2009 and monitored the technical performance and customers’ experience over a 12 month period.
A number of heat pump installations performed very well, achieving an overall system efficiency rating of three and above.
The trial also found that ground source heat pumps had slightly better measured system efficiencies than the air source heat pumps.
Furthermore, it concluded that many of the installations failed to be correctly designed and/or installed, recommending that the responsibility for fitting should sit with one company, who should be contractually obliged to ensure a consistent after-sales service.
Simon Green, head of development at the EST, said: “The trial shows that when installed and operated correctly heat pump technologies will save significant amounts of CO2 in the UK, when replacing oil or traditional electric heating.
“But there is no doubt that the results are more varied than we expected”…for the full report CLICK HERE
