Why are NunnaUuni soapstone ovens special?

For over a century, NunnaUuni soapstone stoves have been crafted in Finland and are valued for their heat retention properties and durability. They not only add coziness to your home, but also allow you to enjoy gentle, long-lasting warmth. In this article, we explain what makes NunnaUuni special.

1. Traditions and craftsmanship from Finland

The story of NunnaUuni begins in the early 19th century in the village of Nunnanlahti in Finland. There lived fireplace builders who discovered a unique soapstone suitable for stoves and fireplaces.

The craftsmen knew that the direction of heat transfer depends on the cutting direction: for the inner walls, the stone is cut perpendicular to the layers, for the outer walls, it is cut lengthwise.

Such precise work ensured that the fireplaces would retain heat for a long time and be durable.

This experience has been passed down through three generations of craftsmen, so NunnaUuni products remain authentic.

2. Mammutti soapstone – an exceptional material
NunnaUuni uses only Mammutti-type soapstone, which is distinguished by its exceptional thermal conductivity and resistance to high temperatures.

The stone absorbs heat extremely quickly and releases it slowly, even up to 48 hours after firing.

A hard layer of periclase forms on the surface of the combustion chamber – a natural “protection” that allows the chamber to last for decades without protective plates or a metal frame.

3. Golden Fire Clean Burning Method

NunnaUuni's patented Golden Fire combustion method (pat. no. EP1008808) allows you to reach very high temperatures at which firewood burns cleanly and efficiently.

This means less smoke and virtually no particulate matter in the exhaust.

Such fireplaces meet EU EcoDesign standards and are suitable for use even in urban areas.

4. The warmth that "hugs"

Thanks to the excellent thermal conductivity of Mammutti stone, NunnaUuni stoves heat up quickly, and their surface gently radiates heat long after the fire has gone out.

Even a short burning time (2-3 hours) ensures pleasant heating throughout the day.

This heat does not "overheat the air", but creates a cozy atmosphere in the home.

5. More than just heating

• NunnaUuni stoves are not just heating devices.
• Some models have ovens that can bake bread, casseroles, or pizza.
• You can choose the Aqua+ system - it allows you to heat water or connect to hybrid heating systems (e.g. solar energy).

6. Customizable to your style

All NunnaUuni models are made individually – you can choose not only the size, but also the finish: natural soapstone or ceramic tiles in different colors.

NunnaUuni soapstone stoves are a natural heat source that lasts for decades. They provide long-lasting warmth, exquisite design, and a unique experience.
