The classic wood insert with boiler jacket. One third of the usable heat is fed into the heating system. The remaining energy of the still high heating gas temperatures goes into typical tiled stove reheating surfaces. These can be metal reheating surfaces for warm air generation or ceramic flues for long-lasting radiant heat. Due to the dimensions of the boiler body and cast iron or steel front plate, the B7 and B8 are ideally suited for replacing appliances in existing tiled stoves. In this way, an existing waste heat stove can be quickly and inexpensively expanded to include water heating.
Consult your stove builder to find the right heating insert for your home.
