Our clients in Centerville, Md were building their custom, dream home. A clean burning, efficient masonry  heater was central to their desires and blueprint. The whimsical, energy efficient home was built on a scenic corner of the family’s horse farm.

The home’s interior reflects the artistic exterior. The timer frame, post and beam construction is entirely built using timbers harvested from the farm property. Structural insulated panels (SIPs) compose the walls exterior walls, providing superior insulation for the new home. To warm the new home, a Finnish contraflow masonry heater is central to the energy design and floorplan. The heater is faced with simple 4″ masonry blocks. The both the living room as well as kitchen side rough block shell is seen in the pictures below.

 

Once the block masonry shell is complete, a rough stucco facing is applied. The living room side of the heater includes a warm, heated bench detail. The double wall, insulated metal pipe chimney exits the fireplace to the top left in the photograph below.

Below the kitchen side of the heater is shown. The optional bake-oven is directly above the firebox doors. Below the firebox doors are two clean-out doors and the center ash clean-out door.

The final heater facing will be a mixture of American Clay stucco and tiles, applied by the homeowner and his family. The first coat of clay is applied to the kitchen side and pictured below.

A client’s great masonry heater testimonial

January 31, 2011 by , under Fire Works Masonry News.

Fire Works Masonry’s client in Rock Hill, NY recently posted some great praise for his masonry heater on his blog:

“Artic Air/ Nordic Heat

The weather has been pretty cold of late. Below zero for the past 4 nights. The masonry heater keeps the place around 60+ degrees with 2 good sized fires per day. This morning it was a 70 degree temperature difference between inside (60) and outside (-10)… and that was 12 hours after last night’s fire had burned out. I’m beyond impressed”.

Thanks, John! Check out his blog and custom home project, WatchTheHouseGrow.Blogspot.Com.

King Of Prussia, PA: Finnish Contraflow Masonry Heater

November 15, 2010 by , under Fire Works Masonry News.

Our clients in King Of Prussia, Pennsylvania have worked for years to retrofit their older home into a modern, zero net energy design. The ambitious plan began with a small addition, improved insulation, and active solar photo-voltaic panels. With these stages complete, it was time to install the clean burning masonry heater into the center of the home.

The homeowner opened the family room floor and built the masonry base to support the masonry heater in the crawl-space below. Once the concrete hearth pad is complete, the masonry heater core and block shell begin simultaneously. The photo below shows the finished high temperature core surrounded by the block heater facing.

The block masonry chimney sits to the left of the Finish fireplace. The masonry chimney transitions to a double wall metal pipe to exit the house.

The block shell is completed after the core. A brick arch spans the bake-oven opening. The travertine bake-oven shelf and mantle are also installed in the block shell. The photo below shows the completed shell and heated bench.

After the heater facing is complete, the two coats of stucco are applied to the heater. Once the stucco sets overnight, the heater door hardware is installed including the loading door, the bake-oven door, ash-box door, and soot clean out doors.

The masonry heater design also includes a large wood storage box to the right of the loading doors.

Tunkhannock, PA: Finnish Contraflow Masonry Heater

November 15, 2010 by , under Fire Works Masonry News.

This old farmhouse in the rolling hills of Pennsylvania has been in our client’s family for over two hundred years. Updating the home to modern standards has been a work in progress for several years. The family improved the insulation, windows, and building envelope. They also added a small addition to fit their growing family. To update the fireplace, the family decided on an efficient masonry heater in the center of their new primary living space.

The Finnish fireplace core was faced with 4″ masonry blocks. The photo below shows the completed rough shell. The blocks will be faced with a plaster coat then the client will apply natural thin stone veneer produced by  a nearby local quarry.

The loading door for the firebox is on the main living room side of the new addition. The rear bake-oven opens into the kitchen space.

Once the block shell is completed, the stucco rough coat is applied. The bluestone heater caps, mantle stones, wood-box cap, as well as the bench tops all came from stone on the farm property. The load bearing timber beam also came from the family’s old barn. The photos below show the first curing fire winding through the heater’s extensive internal heat exchange channels.

The owners of this new home in Carlisle, Pennsylvania have dreamed and planned for years about building a net zero energy home. The design includes structural insulated panels for very high “R” value walls and ceilings, passive solar home alignment and window design, an active solar system on the roof to generate electricity, geothermal heat exchangers to lower the heating/cooling load on the active system, and a clean burning masonry heater as the warm centerpiece of their home.

The passionate homeowners have a detailed blog of the home’s design and construction as well as the home’s performance: http://carlislegreenbuild.blogspot.com.

The masonry heater is located in the main living area for the new home. The heater also acts as a room divider, separating the family room and the master bedroom.

The heater construction starts with the high temperature core, pictured below. This heater is a Finnish contraflow design. The heater will have two down draft channels on either side of the core as well as a long heated bench wrapping around the front of the core. The exhaust gases will exit into a masonry chimney to the left of the core.

After the completion of the high temperature core and heated bench, the masonry facing begins. This heater’s shell consists of bricks and 4″ blocks. The block shell will provide the thermal storage for the fire’s energy and act as the structural base for a natural thin stone veneer application. The shell and chimney are nearly completed in the photo below. The brick facing for the long heated bench is just getting started.

The kitchen side is faced in brick while the living room is faced with natural, local fieldstone. The kitchen will have access to the rear white bake-oven. the living room side will have a long heated bench and a convenient large wood storage area.

 

Viewed from the balcony above the living room, the masonry heater’s design includes brick for the bench and heater cap, granite for the mantle and wood box cap, and local Pennsylvania fieldstone for the facing material. About a quarter of the stones used were from the property’s excavation. The chimney will transition to a metal pipe above the masonry, carrying the fireplace exhaust gases safely through the home.

Perkiomenville, PA Finnish Contraflow Masonry Heater: Heat Kit Core, Heated Bench, and Chimney Installation

February 21, 2010 by , under Fire Works Masonry News.

The owner of this new home in Montgomery County, PA is realizing a life long dream: designing and building a low energy home. The design includes a geothermal system, passive solar heating, high R value insulation, a trombe wall, and a clean burning masonry heater.

The owner placed the heater in the best location possible, roughly centered in the home’s floor plan. He also took advantage of the heater’s thermal mass in the passive solar design. The home and heater are positioned for maximum solar gain during the winter months. The sun’s path tracks over the living room and heater almost the entire day. The masonry heater’s completed Heat Kit core is catching the late afternoon sun in the photo below.

 

The space above the heater opens to the second floor bedrooms. A photo of the heater’s core. firebrick chimney liner, and heated benches seen from the upstairs catwalk.

The completed brick heater will have a heated bench in front and a heated wood box to the right side of the loading doors. The firebrick liner for the heated woodbox is pictured below. The Heat Kit core is wrapped in a fiberglass blanket to allow for thermal expansion.

Below is a photo of the heater’s chimney liner, built with firebricks. The chimney liner, and entire heater, will be wrapped with a brick facing.

The firebrick lining the bench and chimney will add to the thermal mass of the system and increase the heat transfer form the hot exhaust gases. The opening for the simple slide chimney damper can be seen near the top of the firebrick chimney liner in the photo below.
