Abstract

This European Standard is applicable to hot water floor heating systems as defined in EN 1264-1. The determination of thermal performance of hot water floor heating systems and their conformity to this standard is carried out by calculation in accordance with design documents and model: in the case of special constructions and if necessary, the determination of thermal performance by calculation is combined with measurement techniques. This European Standard specifies procedures and conditions to enable the heat flow density of hot water floor heating systems to be determined relative to the heating medium differential temperature for standard systems. For special systems the additional influence factors are experimentally determined and introduced in the calculation. This should enable a uniform assessment and calculation of floor heating systems. The nominal heat flow density, the associated nominal heating medium differential temperature and the field of characteristic curves for the relationship between heat flow density and the determining variables are given as the result.
