Actually the word kaakeliuuni is a Finnish adaptation of the Swedish “kakelugn” and the German “kachelofen”, both meaning “tile oven” or “tile stove”.

Kachel and Kakel mean tile, and uuni, ugn, and ofen mean oven or stove.

English: Cockle Oven?

Wiktionary defines Cockle as, 1) any of various edible bivalve mollusks having heart-shaped shells 2) one’s innermost feelings in the expression “the cockles of one’s heart”.

The conspiracy seems to be two-fold: 1) the shell-tile connection. coincidence?  2) the heart shape of the shell, the reference to innermost feelings, and the masonry heater as the “heart of the home”.

Cheers to the Cockle Oven!  Shown here with Red Cockles and cast iron hardware from Pisla Oy.

These Hens had no idea that the sand was for the stove we were installing right there in the shop, which would have a bake oven, and just the right size too!  And they didn’t know that the bake oven temperatures would exceed 700 degrees during firing, and that it is a “white” oven because the fire and smoke don’t pass through the baking chamber, which allows baking during firing, and eliminates particulate buildup in the oven!

after three years operation. This is a custom hand-built contra-flow style Finnish Fireplace, with a white bake oven. It is a “corner” configuration meaning that the firebox and oven are at a 45 degree angle and the side channels are triangular in shape. More on configurations to come.   A “white” oven differs from a “black” oven because no smoke passes through the baking chamber.  Hardware was custom made by the owner, who is still working on the cleanout door.

Masonry Stoves heat your bones.

The woman is staring out the window, or posing for the shot, or she might be enjoying the heat from the previous day’s fire. She doesn’t seem to be in a great rush to load the stove, and there may be a connection between radiant heat and contemplative states.  There is a small amount of birch that could be burned.

There is now an english version of this page.  Mr. Mayer has built a masonry heater with submarine loading doors, wood stoves from cement mixers, his “pyrariums” are awesome, if a little scary, and he wins the barrel stove design competition hands down.

In this excerpt from a Vermont Commons Interview, Ben Falk talks about Vermonters’ dependence on Hydro Quebec and the Oil Men.

Imagine your home in the following scenario:

The electrical grid is down and it’s not coming back up because Vermont
Yankee had a major malfunction and Hydro Quebec pulled the plug after
deciding that Canada or states downstream needed more electrical power
(and could pay more for it) than Vermont. You’re out of heating
oil and the delivery truck won’t come – even if you could afford the
$5,000 fill-up. It’s January and an “Arctic clipper” is pushing
minus-20-degree air into Vermont. The fridge is empty but you
can’t afford the $10/gallon gas to get to the store. The septic system
is full and the truck won’t come.

Q. So let’s talk about moving forward. How do we think outside the box here?

BF: It’s silly that we’ve put ourselves in such a precarious position,
because there are a few simple and affordable systems that could, at
the home scale, fundamentally change this situation for the
better. One’s called a composting toilet. Another is a big
home vegetable garden, and gravity fed drinking water. Another is
20 fruit trees and a half acre of nut trees. Another is a root
cellar. Another, better insulation and a masonry heater, or at
least a wood stove. For the minority of us who can afford it,
there are solar hot water and electric panels.
