The Golden Fire wood-burning technique has ensured the clean burning of wood in NunnaUuni Oy’s fireplaces since 2000. The technique was invented in 1998, and it has been granted a European patent (EP 1008808). The company exports it´s fireplaces to 15 countries.
NunnaUuni Oy has decades of research activities and fireplace know-how of its parent company, Nunnanlahden Uuni Oy, behind its operations. The founder and chairman of the board of both companies, Juhani Lehikoinen, represents the third generation in a line of fireplace-makers. The company is based in the village of Nunnanlahti in Northern Karelia. Its main product is heat-storing fireplaces made of MammuttiStone, otherwise known as the NunnaUuni fireplaces, and building stones and slabs.

The parent company of NunnaUuni Oy, Nunnanlahden Uuni Oy, was established in 1982, when it also began the industrial production of heat-storing fireplaces. At the beginning of 2007, it signed over its production, sales, and marketing operations to its subsidiary, NunnaUuni Oy. At present, NunnaUuni Oy is the largest privately owned company in its field in Finland.

The NunnaUuni principles include constant, long-term investments in research and product development work. One of the most important results of these dedicated product development efforts is the new gasification wood-burning method patented by the company, the Golden Fire. In making use of this method, research work related to soapstone properties has been important. This research has shown that the main type of soapstone in the company's deposit, MammuttiStone, is an excellent fireplace material.

At the start of 2007, the company had 240 employees. It has an annual turnover of approximately 26 million euros, more than half of which comes from export sales.

NunnaUuni Oy has sales partners in 15 countries.

The Golden Fire


NunnaUuni fireplaces release even heat – cleanly. Thanks to NunnaUuni's unique method of burning wood, the absence of the harmful soot makes the air clear. The method of clean burning we have developed is called the Golden Fire.

This air guiding system patented by NunnaUuni burns the wood in the fireplace in an incredibly hot fire. The high and even heat – with a burning temperature of up to 1,200°C – eliminates the creation of harmful gases. No material remains unburnt, and the chimney doesn't pour out sooty smoke. Therefore, heat-insulating soot doesn't decrease the heat-storing capacity of the fireplace, either, since it doesn't accumulate on the interior walls of the fireplace.
