Home heating and air quality

The air we breathe is vital to leading a healthy life. During summer the air quality we enjoy in Otago is excellent, however in winter, some Otago towns exceed the acceptable level of air pollution under the national environmental standards. Around 95% of this air pollution comes from chimney emissions, and it’s up to all of us to burn cleaner with high performing heating appliances to change this.

How do I know if my burner is inefficient or not? ^

Inefficient burners (coal burners, pellet fires and wood burners) are burners that cannot be lawfully installed or used under ORC’s Regional Air Plan rules. These include:

  • Burners that have an emission rate greater than 0.7g/kg or a thermal efficiency below 65%, in Arrowtown, Cromwell, Clyde, Alexandra; or
  • Burners that have an emission rate greater than 1.5 g/kg or a thermal efficiency below 65%, in Milton

Most wood burners installed before 2007 do not meet these standards.

Check the status of your existing heating appliance here to see if your burner is compliant.  

 

What appliances are approved in Air Zone 1 and Milton? ^

  • Heat pumps (all models)
  • Flued gas heaters
  • Pellet fires
  • “Ultra-low” emission wood burners as per the list below:

What else can I do to help improve the air quality in my neighbourhood? ^

If you choose to use a wood burner to heat your home, please consider that up to 95% of air emissions in polluted towns come from chimney emissions, mainly from burning coal or wet wood.

  • Only burn dry wood (with moisture less than 20%). You can check the moisture level of wood with a wood moisture reader. These are available at most home hardware stores.
  • Don’t burn rubbish, plastic, green waste or electronics.
  • Use kindling and plenty of paper to get your fire started quickly – remember, a hot fire is an efficient fire.
  • Don’t burn coal – it produces more harmful pollutants than wood and may damage your burner.

For more information on what you can and can’t burn, visit our Burning FAQs page.
