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

The Tulikivi TTU 2700 series is powerful and versatile. It comes with an extra-large firebox option which was designed specifically for the North American market. Model options include bake ovens facing either way, the addition of a second firebox door to make a see-through firebox, and both pre-designed as well as custom bench solutions. The TTU 2700 is a top-exit model which means it usually has a chimney coming straight up off the top.

Firespeaking is looking for an assistant to join our team. Our work is creative and rewarding and involves an almost daily fusion of form and function. It is very detail oriented and includes a wide-ranging skillset including masonry, metal work, carpentry, ceramics and design.
This assistant position is partly influenced and molded by the individual seeking the position.
We are looking for someone who can carry out the responsibilities of assistant on masonry heater and wood-fired oven builds in the field. When not working on projects in the field, the assistant would be working in our shop, especially on metalwork for products that we have developed. To the degree that the candidate is skilled and/or interested, there is also potential for gaining experience with the day-to-day tasks of running an innovative business such as website development, answering the phone, office organization, CAD design work using Sketchup and bookkeeping.
While none of these specific skills are necessarily required for the position and can be acquired through on-the-job training, some experience in the rigor and discipline of craft and construction is necessary. The most important asset is a keen interest in the kind of work that we do and motivation to get good at it.
This position could be filled by someone already residing in Eugene looking for a long term employment relationship or someone interested in moving to Eugene for a 1-3 year apprenticeship experience which would prepare them for engaging in similar business in another location. We po have accommodations on-site (Long Table Farm) which can be an ideal live-in experience for the candidate.
Initial pay ranges between $10-$20/hr. depending on experience. Previous bricklaying or metal working experience is an especially strong asset for a candidate. Our work load does vary between 20 and 40 hrs/week depending on whether we are on a project or not. For this reason, it is great if the candidate appreciates having some flexibility to also pursue his or her own interests or activities in parallel to working for Firespeaking or is interested in farm work to ensure full work weeks.
If you are interested, please use our contact form to send a letter of introduction.
