Full Description

Until recently there was a lack of reliable performance data for the design and operation of floor-heating systems. For the German standard DIN 4725, methods have been developed for testing the thermal performance of hydronic floor-heating systems, and numerous measurements have been made. Most of the systems have been tested with the so-called plate apparats.

The results of the tests show that measured values of performance differ significantly from figures published in the literature or company catalogs. It is therefore clear that exact performance measurements under controlled thermal conditions are necessary for the planning and optimal operation of floor-heating systems.

Moreover the standardization of floor-heating systems, with publication in companies' literature, leads to a better comparability between systems and a greater market clarification.
