I built a Russian stove out of cinder blocks for my garage, works great. General idea is to superheat the fire to get near 100% fuel burn without smoke. My main fire burns at over 1200 degrees F and the exhaust is near smokeless at about 150 degrees F. The heat gets trapped in the thermal mass. Step 1 is to build a rocket stove. Step 2 just add the down flow routes. Step 3 add the flu. I spent a few hundred bucks and a few days on the weekend.

Congratulations! Unbeatable will be to custom build it but you need a professional mason who really know this, very rare these days. Real Russian type it’s like 10 times bigger and you cook on it and can sleep on it, only survive in villages and farm homes. Hope they will come back again for private homes as it’s a greatest efficiency of all house “heaters”. Well, you made yours and it’s amazing

Well done, thx. We bought a similar masonry heater kit 25 yrs ago from a Toronto outfit. Had it professionally installed. Love it. Your comment about not being to explain how nice they are until you live with one is so very true. One huge distinction between the contra flow masonry heater and a Russian stove is efficiency. The contra flow design like the Tuli Kivi achieves critically high temperatures in its upper chamber. Time, turbulence and temperature allow complete combustion of the woodsmoke at > 1200F releasing more heat energy. The resistance of heat having to travel down also contributes to greater heat absorption by the thermal mass for later release. Exiting flue temps are 250F. Very nice workmanship on your stove ! Keep up the good work.

Great video. Your explanations of each type of heater/oven is really clear. I understand more now how these ovens work.

I built our house around the Heatkit core here in Alberta. Under-fire air, white stove, and a heated Tyndall stone slab bench to sit or sleep on, along the back. Cinder block construction from the reinforced basement slab up to a cantilevered Q-Deck. I figure 7 tons of stone all in. The veneer was enlarged to hide a mechanical raceway on the opposite side to the chimney connection, leveraged it to preheat cold air by running it over top of the core, down the side into the basement forced air furnace intake. When your architect says "I don't know what a masonry heater is", find another architect. Don't build a house without one. Oh, and don't burn spruce, pine, or fir.

I put in a Crossfire heater 15 years ago and the only maintenance is cleaning the ash drop once a year. One load a day heats for 24 hours. The refractory goes together like lego. You can add granite on top of the brick face or ceramic tile for a different look. Anything you add will increase the thermal mass and store and release more heat.

Hahaha, buddy just wants some attention and a good back scratch 😄 Looks like a great dog and the video was excellent as well!

I would love to see how your parents designed their house around the heater. It looks comfy @

Very smart heating. Would love that in a future house/cabin.

Awesome job mate! I ordered a core from Temp-Cast and will be installing it in the log home we are building. If I do half as good a job as you I'll be happy! Cheers

TuliKivi heaters are built just down the road from us up here in Finland. 🇫🇮 😊

Thank you for the presentation.

Excellent explanation

really good presentation! thank you!

~5 tons of bricks can take quite time to heat up .. but when hot .. warmth for long time.

That was great! Thank you!

The prices for these kits are outrageous. Refractory cement is not that expensive. I would rather build my own forms and pour the cement in place than spend $10,000 on a pre-fab kit.

I would think down draft with a simple secondary combustion would be very good

Is this company alive? Trying to find their website dead please share we love this stove!!!
