Burner types

There are five basic types of fuel burning home heating appliances:

  • gas and diesel burners
  • ultra-low emission burners
  • low emission burners
  • older-style burners
  • open fires

Use the drop-down menus below to find out more about each type and how our home heating measures apply to them

Older technology is being phased out over time and financial assistance is available, where genuine need exists, to enable households to upgrade their home heating systems.

You can also apply for burner extensions in some areas (see 'Registering your burner for an extension' below) to allow for sufficient time to change.

Gas and diesel burners
Gas and diesel burners are generally boilers or gas fires that run on LPG or diesel. So long as they have a rated output of 40kW or less, they are allowed to be used anywhere, with no age restriction.
Ultra-low emission burners
Ultra-low emission burners are any solid fuel burners, including pellet burners, that achieve a stringent real-life emission standard – they are the cleanest solid fuel burners and are allowed anywhere with no age restriction.
Low emission burners
Low emission burners are the most common burners in Canterbury and have been around since the early 2000s. These burners burn wood or pellets and will generally have only one air flow control and will not be able to be banked down overnight. You can use these burners in most areas, but in some Clean Air Zones they are being phased out.
Older-style burners
Older-style burners are generally only common outside of Christchurch, Kaiapoi, Rangiora and Ashburton. They may have two air flow controls, a grate and an ash pan and may be multi-fuel burners. They can be banked down overnight. These burners are being phased out in all Clean Air Zones and in Christchurch they can no longer be used.
Open fires
Open fires are any fire places that are not enclosed and in which air flow cannot be controlled. These burners are being phased out in all Clean Air Zones and in Rangiora, Kaiapoi, Christchurch, Ashburton and Timaru they can no longer be used
