We are often asked how to choose the right woodfire for a particular installation or area.

  1. CHECK YOUR LAND AREA
  • If less than 2ha you can only install a clean-air wood fire approved for use in your local council area
  • If more than 2ha you can install a rural wood fire that does not need to be clean-air approved
  1. CHECK YOUR LOCAL COUNCIL BY-LAWS
  • National Environment Standards permit a maximum of 1.5grams of particles per 1 kilogram of dry wood burnt. However some councils have stricter airshed requirements
  • Wood fire heating efficiencies must be greater than 65%
  1. CORRECTLY SIZE YOUR FIRE
  • Determine the area you wish to heat, and calculate how many square metres this covers
  • Compare your area with the heating area specification included with each fire in the brochure
  • We base our calculations on a nominal ‘stud’ (ceiling) height of 2.4m and make the assumption the insulation of the property is up to current standards
  • If you have a taller stud height or the insulation in your property needs upgrading to current levels you may require more heating capacity. Check with your heating specialist for further advice
  1. CONSIDER YOUR FIRE LOCATION
  • Wood fires can be built-in or freestanding
  • Wood fires are positioned for best flue installation
  • The position of your fire affects how well it can heat your whole home
  • Hearths must protect your floor and comply with regulations
  1. CHECK YOUR INSTALLER IS APPROVED
  • Woof fires should always be installed by an approved installer
  • We suggest using a NZHHA approved installer as they will also help manage the council permit
  • The installer can advise on the best position for your fire and flue
  • The installer should visit your home and advise on the best fire size and type for your needs

HEATING INFORMATION

kW – Kilowatt

The kilowatt rating is the maximum rated output of the fire burning dry soft wood when tested to NZHHA approved test methodology.

M2

Gives an indication of the floor area able to be heated by the fire.  This assumes a normal stud height of 2.4m and an adequate level of insulation in the home.

Radiant

A radiant wood fire produces sun-like warmth as the heat radiates from its steel body.  Heat is produced quickly once the fire is well established, warming people in close proximity.  Ideal for heating smaller spaces.

Radiant and Convention

Heat medium to large spaces with a radiant and Convection wood fire.  The fire creates warm air currents which circulate via convection, warming the area the fire is situated in.  A secondary radiant effect produces sun-like warmth in close proximity to the fire.

Clean Air

A Government requirement for fuel to be completely gasified and burned, producing a minimum of polluting by-products such as smoke, creosote or ash.  Non-clean air fires can still be used in properties located on land greater than 2ha.

Wetback

A wetback makes it possible to heat most of your home hot water needs.  It circulates the water using a thermosiphon effect (i.e. warmer water rises and cooler water falls, creating a natural flow through the water jacket within the solid fuel burner).  Wetbacks can be an even more effective option when coupled with solar hot water.  Talk to our team at Kumeu Plumbing for more information.
