Here we display some of our products and projects
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...
Read MoreWe 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...
Read MoreThis heater is a small masonry heater made after Kuznetsovs drawings that can be found here: OVIK 25 I like this heater, because it is small and cheap to build and heats one normal sized uninsulated room in Azerbaijan. And it has a quite effective small cooktop that also can have a door for doing small bakeries. If floor structures are up to EU-standards it can go on top of a wooden floor. (remember to use some type of insulative bricks at the bottom.) In this case we had to strengthen the structure, because it was a weaker structure.

Read MoreHi just wanted to update you on our first masonry stove. It came out pretty nice. The longer up we came, the nicer mix we got with the mortar made from local mud. At the end it was actually better then the mortar I worked with in Sweden, probably because of a higher clay content. We used: about 570 red bricks 100$ 10 sacks of mud !! Free 0$ 3 sacks of sand 9$ 50 used firebricks 30$ 2 local made doors 10$ 1 local made cook-top and damper 30$ Chimney: 50$ It took us 10 days to finish the whole process with means a local could build it for around 200$ In sum that makes a local business able to install a heater like this for about 430$ . Thats pretty impressive when...
Read MoreLike a living sunlight-battery. One pound of dry wood releases about 8,600 btu’s of energy when burned. Gasoline is only about twice as concentrated. It took a long time for the tree to grow. The daily amount of sunlight was captured and changed into chemical energy. In fact, trees are very much like batteries, storing energy. Wood is like a battery that has been storing energy for decades. The energy is concentrated and ready for use at any rate, depend- ing on need. Also, this “battery” does not lose its charge while sitting, cannot spill acid on your pants, and usually smells good! Burning wood or any biomass also has a great advantage over burning...
Read MoreI got the idea of this stove construction reading a book on how they used to heat medival castels. Offcourse this is a radical downscale of the concept, but the function is somewhat the same. I really like the simplisity of this construction. And I like to think that the “organic” unnsymetrical channels formed by the rocks somehow works better together with the natural flow of gases than channels and chambers… This is neither a bell nor a channel system. It becomes something in between. I know that maintaining a good surfface/weight ratio is important for a good working stove. And I cant think of a more interesting way to obtain that. I rebuilded the...
