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.
I am totally new to masonry heaters, but the concept is fascinating to me. Are the "double bell" design masonry heaters supposed to be more efficient than other designs, or do the different designs have similar efficiencies?
ReplyDeleteDid your heater really only require 55o fire bricks? It seems that the plans I've looked at require many more. How about selling me your plans!! I would love to have a masonry furnace, but I definitely want an oven included.....if you could steer me toward some good plans, I'd really appreciate it! I am looking forward to seeing more of your projects. They are beautiful!
I am still not clear with masonry heaters. Is there much if a difference between this and the regular heaters??
