Small-Scale Combustion Plant Ordinance

Last updated: 5 November 2017
The Small-Scale Combustion Plant Ordinance sets maximum heat losses and pollution levels for combustion facilities with heat output of less than 1 MW (where solid fuels are used), less than 5 MW (liquid fuels) and less than 10 MW (gaseous fuels). The Ordinance of November 1996 amending the Small-Scale Combustion Plant Ordinance further reduced heat loss requirements in new and gas-fired heating systems. Heat losses in existing plants must be progressively reduced to these levels after a transitional period. The length of this transitional period depends on the operational status as well as on the nominal heat capacity of the combustion plant. It amounts to three to eight years from the date at which the amendment entered into force (i.e. 1 November 1996).
