This is an initial photo report of a recently completed masonry heater with inline wood-fired oven built in Grants Pass, OR. The heater uses Balmoral brick and tile details that the client provided, along with polished concrete details made in our shop.
Your choice of brick for a project will have a big impact on the final feel. There are two principle suppliers of brick in the Willamette Valley.
Willamette Graystone supplies brick from the following manufacturers:
Mutual Materials makes their own brick in the Pacific North West.
Here is an exciting innovation combining the advantages of a rocket-fired combustion box with the practicality and efficiency of a wood-fired barrel oven. This idea was developed by Flemming Abrahamsson of Fornyet Energi in Denmark. See also his brilliant Rocket-Fired Griddle Oven Design, which further combines a cooktop griddle to the configuration.

This is an important evolution in the barrel oven concept because it both improves combustion and does away with the need for the additional hardware beyond the barrel of a firebox door, grate and ash drawer. Notice the very simple yet clever sections sketched at 1 and 2 which demonstrate how the flue path is baffled to improve heat exchange.
Flemming has agreed to provide these drawings and the photos of a build sequence for free in order to maximize their potential reach. You can contact Flemming for project specific design/consultation and also for barrel oven hardware in Europe.
Staircases and masonry heaters both provide essential functions yet take up substantial floorspace. Placing a heater near a stair case requires respecting proper clearances to combustibles and can sometimes lead to tricky finish details or awkward spaces. Why not combine these two important functions into one!? Here are some ideas….

We think that there are no current US federal-level tax credits for the installation of masonry heaters. We do not know about any specific state-level programs either. If you know of any examples to draw resources from, please let us know!
Here is a tiny step of progress towards having Masonry Heaters recognized as legitimate modern local biomass fuel burning appliances:Letter to Jeff Merkley Re BTU Act
