Clip Summary
Bob visits with Mark Lundquist of Burnham Hydronics to check out the boiler for the hot-water heating system being installed in the Mashpee, Massachusetts, affordable homes. This Burnham Spirit model is a medium efficiency, easy-to-maintain, sealed-combustion unit. Since it is sealed combustion, it pulls the air it needs directly from the outdoors and vents to the exterior without the use of a chimney or flue. This enables a homeowner to close off the space surrounding the boiler without worrying about available combustion air for the furnace. This model uses standard parts, so any repairs will be fast and easy. The boiler is made of cast iron and has a 25 to 40 year life expectancy. It operates at 84 percent efficiency, so the homeowner will use energy dollars wisely. Charlie Delvecchio of Cape Plumbing breaks out the cost of the boiler to about $1,500 and the baseboard tubing for another $6,000, for a total cost of $7,500 for installation of the home heating system. The domestic hot-water tank is linked to the heating system as hot water from the boiler passes through a coil in the insulated hot-water tank, warming the household water through energy exchange. If the water is maintained at the proper temperature just from this passive exchange, the boiler will never be called upon to heat water for faucets and showers.
