In August 2015 revised Australian Standards AS/NZS 4012:2014 and AS/NZS 4013:2014, relating to emission limits, 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 on wood heater emissions (AS/NZS 4013) tightens the emission limit for heaters (the limit measured in a laboratory test specified in the Standard), in two stages. A lower limit of 2.5 grams per kilogram will come into effect on 8 August 2015, and a limit of 1.5 grams per kilogram will apply from 8 August 2019. This phase in will allow manufacturers time to rework heater designs where necessary, and allow retailers time to clear old stock.
Building Code of Australia
The Building Code of Australia includes provisions for installing wood heating appliances, where a woodheater can only be installed in Tasmania if it complies with AS/NZS 4013.
Check with your Council before having your wood heater installed as notification is required under Building Regulations.
Make sure your heater and any fittings are installed according to the manufacturer's instructions by a qualified builder.
Ensure the installation is carried out according to relevant Australian Standards. A catalytic converter installed in the heater can further reduce emissions.
Wood-smoke is an environmental nuisance. In 1993, Tasmania introduced the Environment Protection (Domestic Solid Fuel Burning Appliances) Regulations.
These Regulations called up the Australian Standard AS4013 1992, requiring any appliance model-line manufactured, or imported for sale, in the State to hold a certificate demonstrating the emission factor is not greater than 5.5 g of particles per kilogram of wood burnt.
In 2007 the Environmental Management and Pollution Control (Distributed Atmospheric Emissions) Regulations 2007 replaced the Environment Protection (Domestic Solid Fuel Burning Appliances) Regulations. The later Regulations require that wood heater appliances manufactured or imported into Tasmania for sale are compliant with Australian Standards (AS/NZS 4013:1999). 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.
