We were approached by a Solicitor with regard to the presumed failure of design in a underfloor heating system. Our work entailed a site inspection during which we investigated the nature and thickness of the wood finish to a large bungalow. The heating system comprised five zones which it was claimed were inadequately designed. The major works consisted of studying the relevant standards and evaluating the heating requirements so as to establish the correct design parameters needed. Our advice was that the works were correctly designed and installed.
