In the winter of 2012 NH SPCA had a wood pellet boiler system installed to provide space heat and hot water in their popular Stratham facility. This 18,000 square foot complex consists mainly of a pet Adoption Center and a Learning Center which are in use 7 days a week.
The new heating system for the Adoption Center utilizes 2 Froling P4 wood pellet boilers (400,000 BTU/Hr combined output) located in the basement. These boilers will provide 80% or more of the heat required for space heat. A silo with a capacity of 28 tons of wood pellets was installed outdoors, adjacent to the boiler room. The existing oil boilers remain in place to act as a back up as well as to assist in peak load conditions. These boilers will contribute heat equivalent to 8,000 gallons of fuel oil each year using approximately 63 tons per year. $16,000 in savings is projected in the first year.
On each day throughout the year, approximately 1,600 gallons of hot water are used to keep all animals and the areas they live in perfectly clean as well as for sterilization, laundry and routine maintenance tasks. The pellet boilers in the Adoption Center will also provide all domestic hot water when needed, as a back up to the solar water heating system by way of a heat exchanger within a new 1000 gallon hot water storage tank that was installed by the solar system contractor. During the winter, the production of DHW will be mainly provided by the pellet boilers while during the rest of the year the solar system will dominate.
Froling Energy also installed a smaller, 130,000 BTU/Hr Froling P4 wood pellet boiler in the Learning Center, connected to an indoor silo with a 4 ton capacity. Projected heating load for this part of the building is the equivalent of about 2,800 gallons of oil. The existing oil boiler also remains in place here. These boilers will contribute heat equivalent to 2,500 gallons of fuel oil each year using approximately 20 tons per year. $5,000 in savings is projected in the first year.
Carbon reductions are significant. The three boilers will offset over 145 tons of carbon each year. This is the equivalent of the carbon emitted annually from 23 cars that get an average of 19 mpg, traveling 12,000 miles per year.
