@@@@Highlights •Residential natural gas heating is proved as a non-negligible source of indoor NO2.•Emission from wall-mounted gas stoves causes indoor NO2 concentration over-standard.•Indoor NO2 concentration is higher than atmospheric concentration on heating days.•Emission grade is a key factor in determining the NO2 concentration in ambient air.•Formulation of NO2 emission standards for wall-mounted gas stoves is urgently needed.
