We covered oven stoves and their long history before, but the stone heaters from the Dutch oven stoves builder Tigchelaar are worth another picture gallery. The models are based on traditional finnish stoves.
The smaller ones (Tigchel heaters) are made up of prefabricated components, made from cement and fit together without the need for adhesives or mortar (dry stacking). Not only can you assemble your own Tigchel heater, but you can also take it with you when you move. They have a floor surface of 70 x 70 centimetres and their height is 115, 150, 185 or 210 centimetres. Similar in dimensions to a fridge, but these stoves are much heavier: 600 to 1200 kilograms.
The "portable" models do not have the heating capacity of the big boys:
"Whether or not the Tigchel
heater can also be used as the main source for heating depends to a
large extent on the insulation of the home. The heater can only be used
as the main source for heating in homes that have been properly
insulated up to the standards of modern times. For that reason it is
also the ideal heater for low-energy homes. These could even be turned
into zero-energy homes when using one or two cubic metres of firewood
over the winter season. "
Heat exchangers can connect a Finoven to a central heating system or a Tigchel heater to a (solar) water heater.

Sunbathing in the living room: oven stoves and heat walls. Why are they gone and how do we get them back?
Halfway intelligent indeed, one or two cubic metres per year keeps a stable balance with the growth of wood on your property. Also, burning wood releases just as much co² as it has filtered during its life. So if every tree that is cut is replaced with a new one this indeed doesn't leave a footprint on the environment. If the tree wouldn't be cut to burn (and release co²) then it would eventually fall and rot, what on its own turn creates the exact same amount of co² gasses.
I wouldn't consider the sellers' statement a lie or commercial bla-bla.

Sorry, I'm more than half intelligent, and I understand what they meant, because I've been following green technology for about 10 years. Low energy homes are called such due to their low demand on external energy supplied by the local electrical grid or gas/oil supply. Calling it zero energy simply means that all necessary energy used by the house is generated by the house, resulting in zero external energy used. This is especially true if the wood is cut from the property where the house sits. Don't complain about market speak until you understand industry speak.

Interesting article, especially the paradoxon of turning a low energy home into one of zero energy by firing two cubic metres of wood per year. So, burning wood does not create energy, or what? Why, then, burn it? The change of definitions by manufacturers in order to sell something is a consistent nuisance to every person who's halfways intelligent.
