Approved ultra-low emission burners (ULEBs)

If you live in Airshed B2 (Stoke) or C (Nelson North), and are either building a new home or do not have an existing enclosed wood burner, you can apply for a building consent to install an ultra-low emission wood burner (ULEB).

A ULEB is one that under strict real life operating conditions can meet an emissions and efficiency standard of 38 milligrams per megajoule, or emits less than 0.5 grams of total suspended particulate (TSP) per kilogram of fuel burned and a thermal efficiency of 65% or greater.

ULEBs are authorised to be installed under proposed rule AQr.26A of Nelson City Council’s Air Quality Plan.

NOTE: In buildings that currently do not have a solid fuel burner, a limit of 999 ULEBs applies in Airshed B2 and 599 in Airshed C.  ULEBs are required to be installed within 12 months of a building consent being issued for the appliance.

Notes and conditions
Emissions = this must be no more than 38 milligrams per megajoule.
P.E.F. = Particulate Emission Factor. This requirement is measured differently for ultra-low emission burners. To qualify for this list emissions are measured under strict real-life operating conditions and must be no more than 0.5 grams of total suspended particulate per kilogram of fuel burned.
S.H.E.  = Space Heating Efficiency. This is a measure of how much of the available energy in the fuel source is generated as heat, and must be 65% or greater.
IB = In-built
FS = Freestanding
