New UFH test proves lower flow temperatures make heat sources operate more efficiently

BEAMA’s Underfloor Heating Group has released the latest results from its collaboration on the BEIS DEEP project at Salford University Energy House, providing further evidence that lower flow temperatures can support heat sources to operate more efficiently. 

The tests are conducted on response times of various underfloor systems with the key aim of providing BRE and SAP, with figures reflecting current installation practices. 

The test site in Salford University allows for laboratory-level monitoring of the system and room temperatures over current SAP standard time profiles. The data is derived from tests of three typical underfloor heating construction types in line with BS EN 1264. 

The data analysed so far has shown that response times of all floor constructions significantly improved on the current SAP assumptions for underfloor heating systems – coupled with the figures to prove that lower flow temperatures also result in the more efficient operation of the heat source. 

Kevin Ray, Portfolio Manager for the BEAMA Underfloor Heating Group commented: “As a group, we are constantly looking at ways to provide the latest, data-driven information and updates on underfloor heating and how it can support the industry to progress to a zero-carbon future collectively. 

“These latest test results prove why low-temperature underfloor heating is the primary technology for heating systems in the UK. As the analysis of this latest data continues, we look forward to sharing more information and updates.”
