Kardonar Apple Tree

We offer sustainable heating solutions and heating systems from domestic carbon-neutral bioenergy.

Comprehensive heating system installation, maintenance and design

Kardonar Bioenergy Solutions Oy has designed, installed and serviced various heating systems since 2005. Our heating systems mainly use pellets, firewood, wood chips, straw and solar energy as their energy sources. All these fuels are fully renewable, and this has been one of our key selling points from the beginning.

Our simplest solution is a wood-burning stove or pellet stove connected to your home's chimney, while our most advanced solution is a mobile wood-chip heating plant that can heat an entire residential area, industrial area or large farm. And of course, we have every solution in between! Our customers often want to combine several heat sources. That's why designing and installing various hybrid systems, and everything that goes with them, has become an increasingly important area for us. We can also supply hybrid heating systems in cooperation with partners, including a heat pump. Feel free to ask us for advice and suggestions on what's available for you!

Would you like to lower your heating costs?

Would you like to use domestic, carbon-neutral fuels, or perhaps burn your own firewood, wood chips or straw instead of expensive oil? Would you like to store the sun's own energy? Or perhaps you'd prefer a simple system with a cosy pellet stove that runs itself for up to four days? If so, you've come to the right place!

Whether you live in an old or new house, have a modern or more traditional interior, or are environmentally conscious or simply lazy, we'll find the solution that suits you and your home best.

Many modern people are so busy that they don’t have time to take care of the heating boiler, and many are used to the hassle-free heating provided by oil or electricity. But now that these forms of heating are becoming increasingly expensive, many are turning their attention to bioenergy. Many fear that heating with bioenergy means a lot more work, but with Kardonar’s products, it doesn’t have to. That’s why only high-quality, easy-to-use products are included in the product range.

Kardonar’s history

Kardonar was founded in summer 2005 in Bromarv, in Tammisaari, to promote the use of bioenergy for heating in Finland. In November 2007, Kardonar moved to Österby in Tammisaari, to better showroom and office premises.
At the turn of 2007-2008, Kardonar acquired a majority stake in Multiheat Oy, which imports Janfire pellet burners from Sweden.

”Amazing customer service that is very personalized and helpful. High end products and a selection of great design and function. Kardonar installed a Pellet stove for me and helped me to make a unique choice that was perfect for my needs. I had a million questions, they were always answered quickly and with expertise. I would recommend this company very happily. There is no where else in Finland that sells such nice pellet stoves, and this is some of the best customer service I have experienced anywhere.”
