In the past hundred years dirty coal, then oil replaced the masonry heater. In northern Europe, 500-600 years ago, a long-lived cold spell caused local wood to become scarce and masonry heaters became common due to their efficiency.
The masonry stove has been around in many different forms in almost all ancient northern cultures, from the 7200 year old Kang bed stove in China to the Hypocaust in ancient Rome. And like a wood stove, a masonry heater can exhaust through a metal flue pipe. A well-designed masonry heater can easily outperform most all EPA rated metal wood stoves.
In a well insulated home, a masonry heater will use 1/3rd (or much) less wood, then a home heated with an old fashioned metal wood stove. A masonry heater always burns wood at the highest heat, if you desire less heat, you simply use less wood. If you tamp down the flue on a metal wood stove you increase the emissions of pollutants as the combustion of the wood is incomplete.
Metal wood stoves must be tended to continually and fluctuate from peak high temperatures, to no heat, when the fire is out. In really cold conditions, you might need to light two fires a day. Because the stored heat radiates slowly from the masonry, it is only necessary to light a fire once a day in most circumstances.

A metal stove gives out its heat rapidly, thus never allowing the inside combustion temperatures to achieve the 1100 degree F plus needed to ignite all the gases. Add a storage battery (the masonry) and you have a very efficient, non-polluting heating system. A slow burning, low temperature, low oxygen fire produces tar and hydrocarbons, a fast, hot, air-fed fire burns the pollutants up. Igniting and then drawing the heat out of the combustion gases turns almost every ounce of wood into energy. If the volatile gases are not fully combusted, they escape as wasted heat and polluting particulate emissions. When burning wood, about 30% of the generated heat is supplied by the wood solids and 70% of its heat is contained in released gases. At these high internal temperatures, the hydrocarbon gases ignite, leaving very minimal pollution. The temperature can reach 2000 degrees inside some masonry heaters (vs 700 inside a metal stove), yet they stay comfortable to the touch on the surface. Inside, masonry stoves burn hotter than metal wood stoves and their winding maze of flue (baffles) warms the surrounding masonry, which then emits heat for 18 to 24 hours. Note: the example materials list includes common brick as the heater veneer, however there are many other veneer options you could go with.Masonry Heaters Also known as masonry stoves, kachelofens, Russian fireplaces, Finnish fireplaces, Swedish stoves, tile stoves, contra-flow fireplaces, radiant fireplaces and mass-storage fireplaces. The items in red on the list are the standard materials that are included on our Heater Proforma invoices and the items in black are the additional materials you’ll need to source (locally, most likely) to complete your heater.

View the AlbieCore™ Materials list for a full list of what will be needed for a heater, including the Albiecore elements themselves. Some of these are available through us and there are others that should be sourced local to the heater (for example, the yellow items in the graphic above are firebrick that do not come with the core because you can typically source them locally). To fully complete a heater, you’ll need a list of other items. The AlbieCore™ package that you purchase comes with these elements as well as some firebox components. The gray-colored items shown on the right side in the drawing above are the actual AlbieCore™ cast refractory core elements.
