Regulations 811/2013/EU (space heating appliances and combination heaters) and 812/2013/EU (water heaters) regulate more detailed requirements.

With Regulations 813/2013/EU (space heating appliances and combination appliances) and 814/2013/EU (water heaters), the European legislator then also defined minimum requirements for central heating systems, which came into force in 2 stages with effect from September 2015 and September 2017 respectively.

For central heating systems for solid fuels and combined systems consisting of a solid fuel boiler, auxiliary heaters, temperature controllers and solar devices, the obligation for energy labelling was introduced with Regulation 2015/1187/EU in April 2017.

The ecodesign requirements and thus minimum efficiency and emission requirements in Regulation 2015/1189/EU came into force on 1 January 2020.

Since 1 January 2015, the already existing requirements of the Federal Emission Control Ordinance (1st BImSchV) of 2010 have contained stricter requirements that will continue to apply at the request of the Federal Government.

According to the 1^st BImSchV, of course, the restrictions on fuels and the inspections due as part of chimney sweeping work naturally continue to apply to all central heating systems – whether gas, oil or solid fuel-fired. Within the scope of these inspections, appliance-specific requirements must be complied with, which may deviate from the requirements of the ecodesign regulations for type testing.
