The ‘household-use low NOx boiler supply project’ replaces ordinary household-use boilers with low NOx boilers. The city government subsidizes up to KRW 160,000, roughly 80% of the replacement cost, and remaining cost is paid by each household. When families replace their boilers with low NOx units, they can reduce approximately 80% of their nitrogen oxide (NOx) emissions and improve energy efficiency by 11% which means the low NOx boilers can improve air quality and reduce heating costs.

Other information
- You can submit your application for low NOx boiler support at the division in charge of environmental affairs at each of the eight counties. For more details on the selection criteria, project priority etc., please contact the environmental affairs division at your local County Office.

- Before you apply, you must check the type of supported boilers (certified Eco-Label products approved by the Korea Environmental Industry and Technology Institute). Low NOx boilers cause condensation therefore you should check if plumbing can be installed for condensation with your boiler manufacturer before installing the unit.
