The 812 AirMax replaced the 802 AirPlus in October 2011. The newer model offers better performance over a wide range of stove temperatures, delivering between 15 and 90% more air flow.
The 812 AirMax provides the highest air flow and starts working at the lowest temperature so this is the ultimate choice. This can be confirmed by viewing the Performance and Efficiency Graphs atwww.ecofan.co.uk/which-wood-stove-ecofan.html
