The 810 UltrAir replaced the 800 Original in September 2012. The newer model offers better performance over a wide range of stove temperatures, delivering between 15 and 90% more air flow.
The 810 UltrAir provides slightly less air flow and starts working at a slightly higher temperature than the 812 AirMax but will still provide excellent results. This can be confirmed by viewing the Performance and Efficiency Graphs atwww.ecofan.co.uk/which-wood-stove-ecofan.html
