Requirements for emissions
Emissions of nitrogen oxides (NOx) from liquid and gaseous fuel local space heaters
shall not exceed the following values:
| Product | Max. value of emissions of NOx mg/kWhinput | |
|---|---|---|
| Old regulation (EU) 2015/1188 | New regulation (EU) 2024/1103 | |
| Open fronted , open to chimney LSH, balanced flue and flueless LSH | 130 | 120 |
| Commercial LSH | 200 | 180 |
For both regulations, NOx is the sum of NO and NO2, expressed in nitrogen dioxide. For 2024/1103, there is an additional requirement that space heating efficiency and NOx have to be measured conoldly.
