In August 2015 revised Australian Standards AS/NZS 4013:2014 and AS/NZS 4012:2014, relating to emission limits, and to power and efficiency ratings for wood heaters were released. Prior to the release of the revised Standards, the emission limit under the Australian Standard (AS/NZS 4013:1999) for any new wood heater sold was 4 grams of particles for every kilogram of wood burned (i.e. g/kg). The revised Standard for wood heater emissions (AS/NZS 4013:2014) tightens the emission limit for heaters (the limit measured in a laboratory test specified in the Standard), in two stages. A limit of 2.5 grams per kilogram came into effect on 8 August 2015, and a limit of 1.5 grams per kilogram will apply from 8 August 2019. This phase-in allows manufacturers time to rework heater designs where necessary, and allows retailers time to clear old stock.
All wood heaters should be installed in accordance with the requirements of AS/NZS 2918:2001 and the Building Code of Australia.
Wood smoke is an environmental nuisance. In 1993, Tasmania introduced the Environment Protection (Domestic Solid Fuel Burning Appliances) Regulations. The Regulations were later replaced by the Environmental Management and Pollution Control (Distributed Atmospheric Emissions) Regulations 2007.
The later Regulations call up the Australian Standard AS4013:1999, requiring any heater model manufactured, imported for sale or sold in the State to hold a certificate of compliance with the AS/NZS 4013 Standard. These
Regulations are currently being reviewed with the intention of adopting the
tighter emission limit for heaters contained within the revised Australian
Standard AS/NZS 4013:2014 and also adopting the updated standard AS/NZS
4012:2014 for power and efficiency ratings.
Before having your wood heater installed
- Check with your relevant permit authority as notification is required under Building Regulations.
- Make sure your heater and any fittings are installed according to the manufacturer's instructions by a person licensed for solid fuel heater installation.
- Ensure the installation is carried out according to relevant Australian Standards. A catalytic converter installed in the heater can further reduce emissions.
