Large Double Bell Heater Core

This is a large double bell heater core built in New Hampshire in early September. 550 bricks in the core. It will be finished in brick by a local mason.

Completed dimensions will be about 44" x 64". The home has R-30 walls and is about 2000 sq ft.

With any heating system, the home itself is responsible for about half the work. The heating device produces the BTU output, and the home has to hold it. In this instance, the home is well insulated, tight, and the heater is large and centrally located- the ideal combination. As a result, my initial feeling is that the homeowner will be able to get through most heating days on a single 60# firing. I'll check in sometime in February and see if that is the case.

This is the completed heater in Shelburne. It takes a while before all the loose ends on some projects are tidied up and the surrounding details are completed.

Clay plaster floor to ceiling on the heater body and large surrounding updraft channel mass. Red and blue glass tile detailing on floor level "kick board", around doors, and under black granite capping stone.

This is a fairly large heater and will have high output when in regular use. It will be interesting to see how even the surface temperature in the large updraft masses turn out to be, and to see what I'll be able to learn about gas flows are a result. The heater has been test fired and performed very well even on a hot day with all the windows and doors in the house wide open.
