Article 3 of Directive 92/42/EEC excludes the following boilers: hot-water boilers capable of being fired by different fuels including solid fuels; equipment for the instantaneous preparation of hot water; boilers designed to be fired by fuels the properties of which differ appreciably from the properties of the liquid and gaseous fuels commonly marketed (industrial waste gas, biogas, etc.); cookers and appliances designed mainly to heat the premises in which they are installed and, as a subsidiary function, to supply hot water for central heating and sanitary hot water.
