Heat Pumps
The question
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the effectiveness of the Microgeneration Certification Scheme regulations for heat pumps operating at flow temperatures between 65°C and 75°C.
Answered by Martin McCluskey
The Microgeneration Certification Scheme (MCS) stipulates that all heat pumps operating at flow temperatures above 35°C are required to be tested and meet a Seasonal Coefficient of Performance (SCOP) of 2.8. Therefore, MCS holds heat pumps operating between 65 and 75°C to the same standards as other heat pumps.
DESNZ consulted in December 2024 on “Raising product standards for space heating” which would introduce a definition and standards for high temperature heat pumps. This would be defined as any heat pump operating at 65°C. A Government Response will be issued in due course.
