TECHNICAL FEATURES
From Palazzetti's constant technological research work, a new heat
generator has been created, an updated version of the proven
Termopalex Monoblocco. A true heating machine, model BI 300 with the
production of sanitary water and model BS 300 without boiler, that is
able to heat the radiators all through the home and, thanks to the storage
tank boiler (a standard feature only on the BI 300 model), supply hot
sanitary water for all the family. It can work as the only heating source
or it can be combined with an existing system.
