EU Ray for Underfloor Heating
For a number of years, underfloor heating providers have claimed that underfloor heating is more energy efficient than radiators, and a study commissioned by the European Association for Surface Heating and Cooling (Eu Ray) has now proved that using underfloor heating can deliver significant fuel savings against radiator-based systems.
In 2005, Eu Ray carried out the first detailed application of the Energy Performance of Buildings Directive (EPBD) methodology for measuring the energy efficiency of buildings, which was developed in response to the European Energy Performance of Buildings.
Its purpose was to evaluate the energy efficiency of three ‘standard buildings’, considering the effects of both radiator and underfloor heating. The selected buildings were in three different parts of Europe – Venice, Brussels and Stockholm – and included a single-family residence, a block of offices and a 15 metre high industrial building. Incorporating a range of buildings in different locations ensured the report considered the varying effects across a variety of constructions and differing external circumstances, thereby adding credence to the study.
Results show that energy consumption can be cut by up to 30% when using underfloor heating compared to a traditional radiator system.
