The Heating Appliance Ordinance ("Verordnung über energiesparende Anforderungen an heizungstechnische Anlagen und Brauchwasseranlagen (Heizungsanlagen-Verordnung - HeizAnlV)") posed requirements to the equipment and dimensioning of central heating systems using water as the energy carrier as well as on hot water systems. Specific requirements additionally applied for single heaters.
The ordinance was issued fort he first time on 22 September 1978, came into effect on 1 October 1978 and was amended for the first time on 1 June 1982. An additional amendment followed in 1989.
The amendment of 1994 generally served as the implementation of the European Directive "92/42/EEC of 21 May 1992 on efficiency requirements for new hot-water boilers fired with liquid or gaseous fuels" (Boiler-efficiency Directive). However, based on the Energy Saving Act (Energieeinspaarungsgesetz - EnEG), only those requirements of the directive could be implemented into German law that concerned the "putting into service" of boilers in buildings. The regulation for the placing on the market of these products could only be implemented after a revision of the construction materials law through the "Verordnung über das Inverkehrbringen von Heizkesseln und Geräten nach dem Bauproduktengesetz (BauPGHeizkesselV)". In this context the Heating Appliance Ordinance was also amended again (Heating Appliance Ordinance 1998).
In the amendment of 1994 several regulations were tightened in the light of decisions of the government concerning climate change. Particularly regulations for the saving of auxiliary power are new. An exception in favour of so called "Passive Houses" was introduced into the ordinance.

In 2002, the Heating Appliance Ordinance and the Thermal Insulation Ordinance were merged into the Energy Saving Ordinance. The current state of regulations for heating- and hot water systems is
