Small Masonry Heater
This 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 MoreFinished masonry stove
Hi 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 MoreHow to cut expences on wood for heating by 100%
A family in rural Azerbaijan typically will burn about 30-40kg wood three times a week to bake their precious bread in the traditional tendir outside. They will do this all through the winter. The heat from this is not trapped in the house, and is solely used for baking the bread. In the cold winter I have many times been staring at the furious fire in the tendir and thought by myself , what a tremendous waste of heat. I just wanted to post some picture on the ongoing project in Lerik. We are making a multipurpose stove for cooking, baking and heating. The total mass will be about 2,5 tonns and max heat output is estimated to 3,5 kw. The stove is very much inspired by...
Read MoreIs woodburning good for the environment?
Like 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 MoreInteresting book on heating
I just came by this free download and wanted to share it. It gives some nice instructions in solar cooker and other interesting designs for cooking on wood. Contrary to my former understanding and to my surprise many villagers here in Azerbaijan still cook on fire, even if gas or electric is available. It is to expensive for the villagers ,that they rather gather some wood for their cooking needs and spend their precious manats for something more important. These simple designs can make cooking much more simple and efficient. Reducing fuel consumption with more than 50%. And mane even more important, reduce smoke and by that inhalation of poisonous gases. Free...
Read MoreMasonry stove workshop with Ekonomka in Sweden
This summer I had the privelage to do a workshop on masonry stoves with Ekonomka. It was a very good time with nice people and nice food in a very nice place called Gotland, a small island outside the coast of Sweden. The instructors, Peter and his wife Tatyana, did a great job hosting this. The where skillfull and knowledgeable, and willing to share their knowledge generously. Their stoves utilies the FMG (Free movment of Gases) that utilise chambers or bells if you like in stead of only channels. This is developed by I. S. Podgorodnikov and later Igor Kuznetsov. This tradition of masonry stoves are brought to the west by builders like Ekonomka.se (Peter and Tatyana...
