Wood Pellet Furnace and Boiler for Heating Greenhouses
Tuesday, April 17, 2012 from 3-6 p.m.
River Berry Farm, Fairfax
David Marchant and Jane Sorenson own River Berry Farm, a highly
diversified vegetable, strawberry and ornamental operation. In addition
to about 35 acres of crops they have 7 greenhouses for production of
bedding plants, field transplants and greenhouse tomatoes. They have
been exploring wood pellet systems for reducing their reliance on
propane to heat the greenhouses. In 2008, an LDJ Amaizing Heat corn
furnace was installed in a 3,000 sq ft greenhouse; it has been run on
wood pellets for several years.
This year they purchased a Maxim outdoor wood pellet boiler with about
twice the Btu output, to heat 2 greenhouses totaling 4,000 sq. ft. They
will describe their greenhouse production systems in general and discuss
the performance of both heating units, as well as the management
considerations and economics of heating with pellets. The farm also
features a heat recovery system that captures waste heat from the
walk-in-cooler compressor to provide hot water on the farm, and a
low-cost hot-water bench-heating system to reduce fuel demand in the
