Although I am commited to burning chunk wood, I went over to Rutland and was given a demonstration of the Woodpecker Boiler by George. I was some impressed with the quality of the unit and the engineering it displayed. Although you cannot see the combustion chamber you are able th see the flame as it fires like an oil burner. It operates altogether different from any other solid fuel unit I've seen. Scavenges and dumps it's ash, modulates with load, cycles off when no call for heat, large fuel hopper and many other features which make it simple to operate. The one thing I could not determine was that if all the features worked without failure but after an hour of poking and peeping, I feel confident with the claims. I was also impressed with George's knowledge as well as Blodgett Supply's many years of quality service in this area.
