BUILDING A HEATER
Fax (425) 742-3361
Designed for people who want a larger fire viewing (door 27" x 36"),
longer burn time (4 to 6 hours every 24 hours) and be able to use standard cordwood for
fuel (5 to 6" in diameter). The Frisch-Rosin can have an oven, front centered
preferred, rear oven possible. The design is based on the Swedish Kakelugn style.
It has a top exit and can have a heated bench. Can be faced with any masonry
FINNISH CONTRAFLOW HEAT KIT
So named because flue gasses on the inner channels flow downward and warm air
flows on the outer side rising(thus contraflow). Sixty five percent of the heat
produced is radiant. The flue exits on a contraflow at floor level, where a heated bench
is possible and the chimney does exit on either side or the rear and can be removed from
the heater up to eight feet away via a heated bench. Ovens are possible, centered
front or rear. The firebox door is centered on the unit and a see thru style is
possible. Facing material: brick, stone, stucco, granite or marble.
Referred to as the Kakelugn. It is a modular core system, rectangular or
round. The rectangular unit is 30" x 40" below mantel shelf and 25" x
36" above the mantel shelf. Round models are 32" in diameter below mantel
shelf and 27" in diameter above the mantel shelf. The door is center front.
No oven is possible and no heated bench. Top exit or rear top exit are
normal. Only minor modifications can be made. Has a heat output of 800 sq. ft.
to 1200 sq. ft. Typically comes with tile or stucco facing, but can be faced with
brick or stone.
TULIKIVI SOAPSTONE FINNISH HEATERS
These are of the Finnish Contraflow type with over thirty models to choose from,

cook top models and combination heater and bakeoven models. The core and the facing
material are made completely of soapstone. The chimney exit is typically at the
base, however some models have a top vent. Sizes vary - can heat 350 sq.ft. to 2000
sq. ft. or more.
An Austrian Kachelofen Heater. Designed by Austrian craftsmen by computer
to heat exactly the area requiring heat. Designs vary from small to large. The

located anywhere on the four sides, center or off centered. Two metal door sizes and
one glass door size are available. Bakeovens and warming ovens are available.
Custom heated benches are possible. The flue normally exits near the top,
horizontally out the side of the heater into a metal or masonry chimney or vertically off

HEATER or STOVE:
For comparison, a standard brick sight built heater is
referred to as a Russian Heater or Stove. Typically they have three to five flue
passages vertical or horizontal. Usually vertical because they are structurally
stronger. Horizontal channels are recommended where gas is the fuel of choice.
The fire viewing door can be either side or either end. The chimney exits at the
top. A see thru firebox is possible, ovens are possible on any of the four
sides. The footprint is unlimited, rectangular or square, three sided or round and
can be built one or two stories high. Facing material can be: brick, stone,
stucco, granite or marble.
All masonry heaters made of brick are Grundofens
All masonry heaters faced with Kachel Tiles are Kachel Grundofens
All stoves of brick or with tile with a convection loop between a metal firebox and the
brick or tile are called Heizeinsatz.
All masonry heaters require a masonry foundation except the smallest Biofire and the
All masonry heaters can be vented into a metal or masonry chimney.
