Heating Appliances

You do not need a building consent for installation of a gas or electric heater or heat pump. However, if you are proposing to install any kind of solid or liquid fuel heating appliance, eg woodburner, multi-fuel burner, open fire, coal burner, diesel burner or cooker using wood or coal, etc, then you should read all of the following information.

A Building Consent application on BA Form 2H is required prior to installing any new or replacement solid or liquid fuel heating appliance. Conditions for the approval of the Building Consent include the following:

  1. Installation of both the fire and flue system to be to the manufacturer's installation instructions.
  2. Smoke alarms are required to be installed.
  3. Application BA Form 6H - Application for a Code Compliance Certificate for a Solid Fuel/ Liquid Fuel Heater is to be competed prior to the issue of the Code Compliance Certificate.
  4. An Inspection of the heating appliance must be completed by a Building Advisor before it can be used.
  5. When a hot water booster or wet back is being installed, a tempering valve (anti scalding device) must be fitted in the supply from the cylinder to the sanitary fixtures. This requirement does not apply if an existing hot water booster or wetback is being replaced. The installation of a water booster or wetback must be completed by a craftsman plumber.

Guidance Notes

  • Flue Height: The minimum flue heights specified in AS/NZS 2918:2001 (Solid Fuel/Liquid Fuel Heaters) or the manufacturer's installation instruction may be insufficient if combustion problems and smoke or odour nuisance are to be avoided. Consideration should be given to extend the flue height above those required by the manufacturer or AS/NZS 2918:2001.
  • Following the inspection you will receive a Code Compliance Certificate provided that the building work has been correctly completed.
  • The cost of one inspection is covered by the Building Consent fee for which you pay at the time of applying for the Building Consent. Additional fees are payable if more that one inspection is necessary.
