    No obvious bad points.

    How we test

    Testing for emissions, efficiency and power output using AS/NZS 4012/4013 was carried out by an independent lab in New Zealand.

    We analyse data from National Environmental Standards (NES) testing to generate scores out of 10 for emissions and efficiency, along with an overall score. This gives us a clear picture of the performance, features and specifications for almost every model on the market.

    Where available, we've also included the NZHHA output results. These results reflect the absolute maximum heat output you could achieve in your home.

    Price is from the manufacturers’ survey and is without a flue kit unless stated otherwise.

    Overall score includes:
    Efficiency (60%)
    Emissions (40%)

      Fantastic Fire..


      The fire is robust, solid without the "bells and whistles" that may fail in the future like "thermal fans & usb's" etc.. Has the highest heat output and has been a dream to run.. Like having the woodbox option under the fire that allows a nights burning to be stored.. fully recommend this fire..


      Nothing to mention..

      Delighted - Ben & Jane Chch


      Easily makes our very large (65 sq m open plan dining, kitchen, lounge) poorly insulated room with large single glazed glass area, very warm and toasty (Chch).
      We initially ran it undamped down and it used more wood, now we find well damped down about 30 mins post starting gives similar heat output and much longer lasting wood than other solid fuel burners we have had.
      Appears to be robust,long lasting construction, good fire brick protection, etc.
      By far the best wood burner we have had of several over many years in different houses. NZ (Chch) made was an added extra nice to have.


      Essentially none. Like any fire, it takes a little time to optimize how to best configure flue dampening and air input controls. Low emission burners cannot be damped down very much for overnight burning (so unsuitable for this) because that creates too high emission output (smoke). Cannot have it both ways, or not with available technology to date!

      Yes, I recommend this product.

      Worst fire we have had the displeasure installing


      NOTHING, worst fire we've ever had, hopeless getting up to a cold home in the morning, unless u want to be up every 2 hours adding more wood, uses more wood as unable to close down, at times we get a room full of smoke as it blows out from everywhere, all other fires we've had r far superior to this.


      Every time it's a bit windy, flue sounds like a train coming through the house, at times get a boom & out comes smoke from everywhere, lose any heat gained having to open house up to get rid of the smoke, bloody joke

      Recommend it?

      No, this product has too many drawbacks.
