The Flat system masonry heater kit is used by the stove builder whenever the customer does not want a specific design for the custom stove. In this case, a custom stove combustion chamber is simply combined with a matching modular storage and cladding kit. The surface of thermal concrete is always untreated by default, but can be sealed with wax. It can also be painted or plastered, giving it a very individual look. The heater can thus be built up quickly and inexpensively.
Consult your stove builder to find the right heating insert for your home.
