"I really love my masonry heater. It's the perfect place to stand next to when coming in from working outside in the fall and winter months, it really warms me up fast. A 62 degree air temperature with the heater feels like 74 with the old forced air furnace."
-Charles Knerr, Scottsville, NY
A masonry heater is a partial or whole house heater which operates by capturing the heat generated by a quick, hot wood fire lasting just a few hours, then releasing the stored heat over the course of a day. It differs from a traditional wood stove in that it has a large thermal mass, which stores and releases heat long after the fire has gone out. This feature, coupled with the construction to take a quick, intense fire, allows the masonry heater to provide the same amount of heat as a traditional wood stove, while burning for 10% of the time and using only one third to of the wood of a traditional wood stove.
Masonry heaters have their roots in many different countries in Europe and Asia, where limited wood supply necessitated a very efficient appliance which could radiate heat for hours with just a small amount of fuel used. As with other things, each culture developed it's own type of masonry heater, giving them unique names based on their history or construction: contraflow, kachelofen (tile stove), putzofen, grundofen, kakelugnar, kakelugn, radiant fireplace, radiant stove, Russian fireplace, and others. At Empire Masonry Heaters, instead of focusing on one of these technologies as other companies do, we like to take the best ideas from all of these technologies and incorporate them into our masonry heaters.
At Empire Masonry Heaters, we strive to produce the best product we can through third party testing. Two different models of our masonry heater core kits have been tested at a third party, accredited EPA lab, and both units tested well under the Colorado and Washington State regulatory limit on emissions. Additionally, our Envirotech Classic core is on the approved list for Washington State, satisfies the requirements of Colorado Air Pollution Control Regulation Number 4, Section IV, and also qualifies for a $300 tax credit in the state of Oregon. You can read more about the testing at our Lab Tests & Regulations page.
At the center of every Empire Masonry Heater is the Envirotech™ Radiant Fireplace technology. Our heaters are the only American-made, third-party tested, modular heater kit on the market. After numerous years of research and training with several European master stove builders and their experience building hundreds of masonry heaters in North America, the creators of the Envirotech™ Radiant Fireplace designed this easy-to-build kit-type masonry heater using innovative, precision cast components which lock together for ease of construction. Empire Masonry Heaters now exclusively manufactures the Envirotech™ for customers on the East Coast.
We've dug out some old videos to so you can get an idea of how our cores go together. The video is in 4 parts and is approximately 35 minutes in length. By watching it, you can get a good idea of how our quickly and easily our heater cores go up.
