Soapstone (steatite) is a magnesium silicate that was formed under great pressure and intense heat millions of years ago. There is nothing quite like soapstone as it possesses extraordinary heat retention and transfer properties. Unlike other natural stones such as granite and marble, which can also store and radiate heat, soapstone has such an unusually stable composition that it can withstand direct flames indefinitely and be subjected to great fluctuation in temperature with little expansion or contraction. Simply put, it stores and transfers heat better.Although soapstone is a soft rock, it is not porous and has a solid structure that has amazing heat-retention properties. The practice of heating stone for its warmth retention qualities has been known for thousands of years. Stretching back to ancient times, man used heated stones to keep warm and to cook food. Now, Greenstoneheat combines this long-known practice with state of the art engineering, technology and design to bring you the finest heating source in the world… a soapstone masonry heater.
Many of our customers ask what makes a Greenstoneheat soapstone masonry heater so special and so different from traditional wood stoves, even those wood stoves wrapped in soapstone. The answer is in the soapstone masonry heater’s mass, or weight. Soapstone holds twice as much heat per pound as iron or steel. An iron wood stove weighs a couple hundred pounds, more or less. A soap stone masonry heater weighs thousands of pounds, generally more than less. In it, a brisk, hot fire is burned once or twice a day. The heat from the fire is transferred to soapstone itself where it is gradually released into the surrounding area, a steady radiant heat. Instead of heating the air directly, the radiation warms the solid surfaces in the room and will even pass through walls and warm adjacent rooms. Long after your fire has died down the soapstone masonry heater keeps on radiating heat. Following is a chart that compares the properties of different materials which can be incorporated into masonry heater installations.
What is a Masonry Heater?
Efficient :: Clean :: Warmth
A soapstone masonry heater is the best wood heating device the world has ever seen. It is comprised of a scientifically designed firebox, surrounded by heat exchange chambers that ensure the efficient warming of the adjacent thermal mass. Wood fires are burned very fast and the energy is retained in the thermal mass of stone. The heater releases comfortable radiant warmth for 12 to 24 hours, heating your home and contents, not just the air inside.
How It Works Capture :: Store :: Release
Masonry heaters are designed with a relatively small firebox, designed to maximize Combustion Efficiency or how quickly and completely the wood and gases are burned. Our heaters contain scientifically designed heat exchange chambers and a huge thermal mass of soapstone, designed to maximize Heat Transfer Efficiency or how well the heater transfers heat into house versus up the chimney. Simply put, our heaters utilize a renewable fuel source to heat your home in the cleanest, safest, most comfortable way known to man.
Benefits Health :: Safety :: Comfort
We believe that nothing is more important than the health of our friends and families. Forced-air furnaces, stoves and fireplaces dry out the air, increase airborne dust and allergens, dehydrating the body and increasing allergies. The slow release radiant comfort of a masonry heater is safe for your children to touch and eliminates the cycle of hot and cold common in other wood heat. Discover the benefits of health and vitality only available in a soapstone masonry heater.
A masonry heater is a vented heating system of largely masonry materials (soapstone and fire brick are common) weighing at least 1760 pounds excluding the chimney and masonry heater base. A masonry heater is designed to capture and store a substantial portion of the heat produced by a fire, which burns rapidly and rather completely at high temperatures in order to reduce unburned emissions. It is constructed of sufficient mass (i.e. weight) and surface area that under normal operating conditions, the external surface temperature of the masonry heater does not exceed 110 degrees except in the immediate area surrounding the fuel loading door(s).
A masonry heater allows you to heat your home with wood in a unique way. Its main distinction is the ability to store a large amount of heat. This means that you can rapidly burn a large amount of wood without overheating your house. The heat is stored in the masonry thermal mass (the weight of the stone), and then slowly radiates into your house for the next 12 to 18 hours.

A Greenstone Heat soapstone masonry heater may enhance the environment, safety and comfort of your home, as well as your health. They are safe, efficient and comfortable to live with. Also, the warm grain and color of soapstone masonry heaters make them beautiful “pieces of furniture” you can build a room around. Or in the present-day vernacular, they add architectural detail. Masonry heaters are gaining popularity among people who prefer using renewable resources. Wood fuel is also cost effective from an economic stand point. A recent price comparison using energy prices in the Northeast shows that wood is half the cost of fuel oil and natural gas, one-third the price of propane, and one-quarter the cost of electric heat. And because they use up to one-third less wood than conventional wood stoves, the case for masonry heaters is convincing. The following graph compares the costs of different types of energy:
