Start admitting you need storage and you are in direct competition with Garn. Hmmmm? It's the Euro way and also the reason Martin designed the Garn the way he did some 30 years ago. Adequate..........and I do mean adequate in terms of gallons per output of the boiler as well as the load served. It just takes a lot of complexity, babysitting and complication out of wood burning. Mark O'Dell told me that when they started selling EconoBurn he estimated that maybe 5-10% of the units went in with storage. The percentage is now over 80% from what he told me. Sounds like people are getting on the right track for gasification and btu storage to me. That's a good thing.
