Outdoor Cordwood Gasifier for Greenhouse Heating at High Ledge Farm, Woodbury, VT

Chris recently collaborated with Paul Betz at High Ledge Farm to assess, plan and implement the outdoor wood gasifier installed for greenhouse heating at the Woodbury, VT farm.  A report on the project can be found on the UVM Vegetable and Berry page in the case study section.

The heart of the system is a Central Boiler, eClassic 2300 which meets EPA Phase II emissions regulations for outdoor wood boilers. Paul intends to purchase cord wood cut and split and delivered at a price of $210/cord. With an installed heating system cost of $21,826 and 3 month use (last week of March through May) the system will result in $1,915 savings annually compared to the use of propane fuel purchased for $2.56/gallon. When fueled by renewable cord wood at current pricing for wood and propane the system will have a payback period of 11 years and avoid roughly 6 tons of CO2 emissions annually (equivalent to approximately 14,441 miles of average passenger car travel.)
