So you want a masonry heater?
These are the steps for planning and various options.
1. Is this a retrofit or new construction?
2. What is the supporting floor made from? Will it be able to hold 5+ tons of additional weight? Does it need re-inforcing?
3. What square footage of home are you heating?
4. Remember this is a radiant heat source so you will not feel the heat radiating to you unless you are in direct line of sight to the heater.
5. Where is your chimney routed? Is there a current chimney chase? Where does it exit the roofline?
6. What type of core do you want?
7. Do you want a bakeoven? Black or white bakeoven?
8. What type of veneer do you prefer?

- Building Code Coverage of Masonry Heaters (PDF File) by Norbert Senf, Masonry Stove Builders
- Codes and Standards for Masonry Fireplaces and Chimneys by Jim Buckley, Buckley Rumford Fireplaces
- Available for purchase from ASTM International.Â From website description: “This guide can be used by code officials, architects, and other interested parties to evaluate the design and construction of masonry heaters. It is not restricted to a specific method of construction, nor does it provide all specific details of construction of a masonry heater. This guide does provide the principles to be followed for the safe construction of masonry heaters.”

Every bakery is different. Ovens should be designed accordingly.
Consider some of the variables that may affect the design of a commercial oven:
- production goals and schedule
- breads, moisture contents of dough and grain types
- baker preferences and ergonomics
- steam requirements
- desired baking temperatures
- type and quality of available fuel
- retrofit details while fitting into existing spaces
- door systems
- foundations, wood storage, ash clean out
- available materials
- masonry veneer materials and style
Some of these variables will effect the overall shape and size of an oven significantly. For other factors the tweaks in design are more slight, and reflect an intention in use patterns that are then reinforced and developed as a baker learns to fire and bake in the new oven.
If you are interested in a plan set or having an oven built our initial conversations will cover all the variables listed above, with an interest in learning about current baking practices and production. From there we discuss what you want from a new oven and how it will meet your future production goals.
The next step is beginning the design process. This can mean anything from starting from scratch to working off what have become stock designs, and anything in between. No two ovens are exactly alike, as they all reflect the particulars of individual project needs. As the oven is designed the drawings are often exchanged with the client for feedback and adjustment. This continues until we arrive at a completed design.

Once design work is complete, and the nuances of the specific installation are understood, an estimate is created for the installation of the oven. Often baker/owners are able and willing to handle some of the construction details themselves, such as foundation building, insulation and surround, chimney work, etc. In this case, responsibilities for the different phases of the build are agreed upon and laid out in the overall installation contract.
Unless your location is around the corner from Burlington, VT the baker/owners may be responsible for room and board for our masons. Most oven builds require between two to six weeks, depending on the size of the oven and the scope of the project.
Bake ovens in domestic settings can cost between $7,000.00 to $20,000.00, depending on a broad set a variables.
Bake ovens for commercial bakeries typically cost between $20,000.00 and $40,000.00, again depending on size of oven, installation details, and scope of project.
All design work and oven installations are quoted independently. During initial design consultations we quote only a general price range for a project. Only after design work has been completed, components drawn and priced, materials delivery to your location assessed, etc we are able to offer a formal quote for your project.
