Masonry heaters are also called Finnish masonry stoves, German tiled stoves, Russian stoves, Kachelofens, and Russian heaters. Wood heats the fireplace and stores heat for hours of warmth. Although less used in to North America.
Discover the warmth and efficiency of the Temp-Cast Masonry Heater Fireplace, a modern take on traditional wood heating. Designed with advanced masonry construction, this fireplace captures and stores heat from a short, clean-burning fire, then slowly releases it as gentle warmth for up to 24 hours. Unlike conventional fireplaces that waste energy and require constant tending, the Temp-Cast masonry heater delivers steady, efficient heat throughout your home while using less wood and producing minimal emissions.
Have you been through a winter where you lost your main heat source, or worse, total power? Traditional indoor fireplaces can be a hassle. You have to constantly feed the fire, clean up the ashes, and the warmth disappears as soon as the flames die out. The Temp-Cast Masonry Heater Fireplace solves all that.
What sets this unique fireplace apart from the other units you see on the market is its option to have a bake/pizza oven upgrade! This high-performance fireplace is engineered for efficiency and comfort. Its dense masonry core absorbs the fire's energy and radiates it evenly long after the flames go out—keeping your home comfortably warm day and night. That means fewer refuels, less wood consumed, and a reliable heat source even during power outages.
The main difference between a masonry heater and other wood-burning appliances is that a masonry heater can store a lot of heat. This means that you can quickly and cleanly burn a load of wood, and the heat will slowly radiate into your house for the next 8 to 24 hours. Masonry heaters are also safer and more efficient than traditional fireplaces since they don't produce creosote or harmful emissions in the chambers or flue.
Hot air from the fire flows through a series of baffles to heat up the surrounding masonry. This heat is "soaked up" in the heater walls and then slowly released into your home.

Having a renewable energy source that you can harvest locally gives you peace of mind. You can burn it cleanly to heat your home without relying on electricity. Testing showed that the Temp-Cast heater has a transfer efficiency of 65.4% and a combustion efficiency of 94.4%.
The modules are manufactured from a castable refractory material. They have a unique interlocking feature so that one piece is precisely keyed to fit the next one. This allows the kit to be quickly and accurately erected and ensures that the completed core is structurally stable and independent of the facing material.
There is no safer wood-burning fireplace than a well-made masonry heater. It can be fired for a few hours per day while you're awake and never at night when you sleep. Because they burn the fuel so completely, they produce little ash or harmful emissions which keeps your home's air cleaner.
One of the most distinctive features of a masonry heater build is the outstanding fire-viewing. When the fire is lit, it catches quickly and burns fiercely, creating a spectacular show. If a pizza oven is incorporated, you can see the burning gases accelerating through the gas slot, creating an exciting "spark shower" and adding to your enjoyment of the fire.
Masonry heaters are a household word in colder parts of Canada, Northern Europe, and Australia. Temp-Cast masonry heaters can serve as the primary heater in a well-insulated 2000 square foot home while using less wood, therefore using less storage space.
Radiant heat from a masonry heater is very similar to the radiant heat from the sun rather than the convection heat from a traditional fireplace. Just as the sun warms the earth, the masonry stove heats by warming solid objects in the home, such as walls, floors, furniture and people.
CUSTOMER FEEDBACK
"Now after three winters, I’m eager to report that our Temp-Cast 2000 has exceeded expectations. This technology is rare in Virginia; several friends, visitors and subcontractors became immediately impressed with the performance and the aesthetic impact.
"Aesthetics versus performance? I cannot say which feature is best; it’s all wrapped up in one. Having only experienced wood stoves and such, my wife was concerned about indoor air quality. She was astonished by the masonry heater’s total lack of combustion odor.
"As a professor in Wood Science, my career revolves around wood. I cannot explain the satisfaction it brings to heat our home with the most efficient, environmentally responsible, wood-burning technology available to homeowners. We love it."

Do I need to have a footer to instal this or can I just intall on my existing flooring?
Depends on where you are installing it. These units can weigh thousands of pounds when you have them all set and done and so its important to have a good foundation in place to allow for the heater to be put on top of.
