Soapstone Fireplaces


Soapstone is a naturally occurring material with very interesting thermal properties. Compared to other masonry materials used in masonry heating technologies, it conducts heat more than twice as fast as a standard refractory and therefore it makes sense to use it as a heating material. For full comparison of materials click the chart below. Disadvantage is higher price and less resistance to thermal shock resulting in relatively lower life expectancy than standard refractory masonry stoves.

Our soapstone heaters have been developed by our partners in Netherlands and have a completely new combustion chamber which has been tested successfully according to the European standard EN 15250, resulting in very low emissions for dust and CO with efficiency as high as 86 % hence all our soapstone heaters are CE marked

Carefully selected soapstone from Finnish quarries combined with the latest technology result in high quality, long lasting and sustainable products.

 

Our soapstone stoves and fireplaces rely on the "contraflow principle", under which the hot flue gases which rise from the fire are first ducted to an upper chamber where they undergo secondary combustion and are then directed down through the side channels.

The solid soapstone structure draws all the heat energy from the flue gases into itself and stores it internally, gradually giving it out over a long period.

Thanks to soapstone's good heat conductivity the heat is directed to the outer surfaces to the stone and travels from there to the surrounding room space.

Soapstone stoves warm the interior purely by radiant heat, a process that is comparable to the way sunshine warms the environment on a still, sunny day. One of the characteristics that makes the natural soapstone so exceptionally suitable for use as a stove is its capability to store heat; this means that during a relatively short period of fierce combustion (1-3 hours) a soapstone stove will absorb a massive amount of energy, which it then transmits slowly and steadily as gentle, radiant heat over the next twenty-four hours, filling your home with a friendly warmth and creating a comfy, healthy atmosphere for the whole family, which is beneficial especially for asthma and allergy sufferers who will benefit from a soapstone stove, because radiant heat does not produce a constant airflow, as is the way with conventional convection heating systems. This eliminates the constant movement of dust particles, which can be a cause of considerable grief over winter.
