Condensing gas boilers with or without associated controls, space heating and DHW storage systems; and/or a gasification installation (a gas piping system) of a dwelling starting from the boundary gas meter (owned by the gas distribution company) all the way to the connection to gas appliances and comprising of piping and equipment, as well as chimneys or flue pipes discharging the fumes and gases from the gas appliances into the outside atmosphere. When the boundary between the distribution network and the gasification installation is outside of the dwelling, the gasification installation includes all the piping with or without any associated equipment outside the dwelling between the boundary gas meter and the connections to all gas appliances in the dwelling.


Eligibility Criteria:

Seasonal space heating energy efficiency ηs ≥ 90%  (gas boiler energy rating “A”, “A+”, “A++” or “A+++”) in accordance with EU Ecodesign Directive („ErP Directive”) 2009/125/EC Regulation 813/2013 (minimum efficiency standards for space heaters and combination heaters); EU Energy Labelling Directive 2010/30/EU Regulation 811/2013 (energy labelling space heaters and combination heaters); BG Ordinance (of 09.06.2004) on the connection to the transmission and distribution networks; BG Ordinance (of 09.03.2004) on the organization and safe operation of transmission and distribution lines, facilities, installations and equipment for natural gas; BG Ordinance (of 25.11.2004) on the technical rules and standards of design, construction and use of facilities and equipment for transmission, storage, distribution and supply of natural gas.
