Thermal Insuliation for Zuzia Tunnel Boiler Stove

Thermal insulation of the insert with a water jacket makes it
possible to considerably reduce heat loss in the water heated and
directly influences an increase in the efficiency of the fireplace
insert even by 10%. It also protects the fireplace housing against
heating and prevents vapor condensation on the elements located
both inside as well as outside of the fireplace insert. Thanks to
that, the maximum amount of heat is supplied to the heating
system.
Additional application of the insulation also reduces the amount of
wood burned, and, thus, guarantees more economical burning.
This means that when you use it, you need less wood to obtain the
same temperature. Thermal insulation of the fireplace insert with
a water jacket is made of zinc coated metal sheets and insulation
wool protected with aluminum foil.
