Thank you for following this blog so far!

For some years I have updated this blog with some of my development of different heating solutions for houses in sothern Azerbaijan. It has bean a steap learning curve with lots of trying and failing. The last years development and interests has resulted in the establishment of “Provitaz MMC (LTD)” This will be a company to sell our knowledge and products that we have developed and by that make it commercially available. Hence this is where most of my focus will be the comming years. However I intend to make things that is interesting to “do it yourselfers” available here from time to time. I still believe that community development is the best...

Sketchup for masonry heater

This is the sketchup for the multipurpose heater based on Alex Chernovs “Russian Rocket” that he showed at the MHA 2012. This tries to give a cheap alternative to the rocket-stove comunity. But at the same time fasilitating the convenience of a true masnory heater.  It really burns well and is easy to operate. It also burns clean and uses limited amount of fuel. This version that we wrote in Sketchup is somehow bigger since the bricks I am using here in Azerbaijan are bigger.  There is not a shut-off damper. This I put in the chimney in the floor above the heater. But there is a bypass for summer use and cold starts.. . The bake oven door neads to be...

Sketchup for the Kitchen stove

I hope it can help someone. Use the tool “section panel” to view the layers, and the tape measurer to find the dimentions. Here is the Sketchup !

Masonry kitchen stove

We builded a new small heater that we think will be very popular. This stove combines direct heat and stored heat. It is a fast and simple build, but it performes really well. This stove responds to many of the neads expressed by the people here. Learning for Winiarskis design principles I figured that a pushing the fire in a narow gap under the coock surface should result in a more effective heat transfer. (Sketchups are on the way) This stove is amazing to coock on because on one side you have frying hot temperatures and on the other side it is suitable for slow boiling and simmering food. The design makes the coocktop a more effective heat-exchanger than it normally...

Small masonry heater video

This stove performs way better than you should think. Offcource flu gases dont come down towards the most effective larger masonry-stoves but it heats the room really well with going through less than a 1 kubik meter of wood in a month ! And the room temperature in the morning is just slightly colder and heats up quickly. Comfort and dryness of the room is very different than with a conventional stove. Total cost of the stove is around 65 AZN. That is less than 100 USD.  With the wood price here in Azerbaijan it pays back within one winter! Expected lifetime? Ill give it some decades with minor maintainance.

Some reflections on materials

Some reflections on materials

Obviously we are making our heaters with completely different design criterias than what we would do back home. We recieved some questions about this. And here I want to clarify why we are doing this, and why you should consider mabe not to do the same thing in your place. There are different conciderations that make us to do things differently here than back home, to point out some: Different general expectations to qualities of products. (If a heater here lasts 20 years it is 20 times better than the local heaters that burn hole in them through one heating season) The desire to make things available for everyone. Economy is bad, and making a heater that costs 10 000...
