Our assessment

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.
