Wood boiler cuts school costs

RAY BROOK — Saranac Lake Central School continues to show savings from a new heating system installed last year.

Business Manager Dan Bower gave an update to Adirondack Park Agency commissioners recently on the wood boiler installed at Petrova School.

He delivered financial details alongside Dave Dungate, president of Advanced Climate Technologies Bioenergy of Schenectady, who installed the equipment, and school Facilities Manager Lee Daunais.

HELP WITH COST

Bower said actual installation costs came close to $513,000. 

But the New York State Energy and Research Development Authority provided a $410,000 grant to offset that cost, with $102,000 match required.

State education building aid supplied half of the match, leaving $46,000 for taxpayers to fund in the end.

BIG SAVINGS

The boiler is already starting to pay off.

Bower compared heating costs for the month of December this year to last.

In 2011, they burned 8,002 gallons of fuel, which cost about $25,000. But this past year, the school burned 1,500 gallons of fuel at a cost of about $5,000 plus $6,400 in wood pellets — saving more than $13,000 in December alone.

The school buys pellets in bulk from a biomass distributor in Massena, Bower said.

Daunais declared he is just the “nuts and bolts” guy, but provided commissioners with details of the day-to-day operation.

The 132,000-square-foot, three-story school with an add-on gymnasium maintains the oil boiler online as a backup, he said.

MORNING WARM-UP

The only issue with heating with wood came with the warm-up period in the morning.

The school’s heating system runs at two temperatures: one when students are present, and the other when the building is empty.

“What we found out is when I got there at 6:30 (a.m.) and the temperature is down, the whole load (on the heating system) is opening up at the same time. Through energy management, we’ve programmed the system to bring it on in steps,” Daunais said.
