"We've become a steward of our local environment, we've become a sustainable business and with phase 1 we have eliminated more than 1/3 of our oil consumption." Henry Huntington, owner Pleasant View Gardens


Floriculture operation

In 1976, Jon Huntington and his family moved from their five-generation family farm in Connecticut to Loudon, New Hampshire. His goal was to revolutionize a wholesale floriculture operation in New England. The cornerstone of the company's success was and continues to be attention to customers' needs and innovation in all aspects of the company. Whether it was building one of the area's first gutter-connected ranges in the late '70's, automation in the '80's, co-founding Proven Winners in the '90's or winning recognition as one of the top suppliers of vegetative products in 2005, Pleasant View's goal has remained steadfast - unprecedented customer support and innovation at every turn. - www.pvg.com

Pleasant View operates commercial greenhouse facilities in Pembroke and Loudon. At peak season, their full operation covers 12 acres of greenhouses and employs up to 250 people. Between the two facilities, the company burned as much as 650,000 gallons of oil annually. Working with Thermal Systems to convert to a biomass boiler system, PVG has reduced fuel consumption by more than 1/3.

Pleasant View Gardens secured a USDA grant to help fund the project. They now burn wood chips in a Hurst biomass boiler to maintain ideal greenhouse temperatures in the Pembroke facility. The next goal is to transition the second facility as well to make the company fully sustainable and a good steward of the local environment.

PVG chose Thermal Systems as their partner in this project after looking at other operations that had converted to biomass. "Bob Waller took us to see other biomass installation projects and we liked what we saw. The Hurst biomass boilers seemed to have the happiest clients," explains Henry Huntington, owner of Pleasant View Gardens. "Bob had the knowledge and experience with biomass that we felt was needed to ensure success."

"Working with Bob and the Thermal Systems engineering team to install the system was seamless. They worked well with the other contractors we needed on the project. Their team gave us the confidence that the transition would go well. And it did. We had some typical start-up issues that were quickly resolved. Everything, from start to finish, was handled quickly, expertly and professionally."
