    Tesi H2O

    It takes up little space and easily fits in your interior, where it heats the radiator’s water and also spreads out over 1.500 Kcal/h through the glass door. Cleaning is very quickly done, with no need to disassemble anything: the exchangers are perfectly clean within a few minutes thanks to a practical system of brushes. Just like the Venexia and Murano models, it is fitted with all the hydraulic safeties and also: 8 lt. expansion vase, 3-way diverter valve and electronic circulator. A 26 kg pellet hopper allows a great operation autonomy.

    On the return circuit, a chemical-physical water treatment system must be installed, for instance a magnetic dislimer.

    Anti-condensation valve to be installed.
