What did stoves burn in the 19th century?
In the castle and then in the neighboring villages, the researchers paid attention to the stoves. The slits on them were represented in the form of a radiation sign. Such furnaces have a somewhat unusual structure.
It doesn't make sense to heat them with coal, the fuel consumption is too high. Many models do not have pipes at all, as if they do not require smoke removal. Such stoves also have Radium markings.
Radium stoves can heat huge rooms, unlike any fireplace or wood stove.

Why are heating elements called RADIATORS in the Czech Republic??? 🤔
