[Stoves] Pebble bed three stone fire

Thu Nov 7 08:36:53 CST 2019

Dear Friends

This is a photo of the three stone fire with a set of stones in it, and a clay grate as an aeration device.

In the past 8 months about 3 million people have adopted this as a fuel saving and emissions reduction "device".

The retention rate (continued use) is in the high 90's % range. It's effect is obvious and basically free.

This is a demo presented by SNV after the ISO meeting.

Regards
Crispin
