APPLICATION
Heating hot water storage and D.H.W. production.

MATERIAL
• BUFFER TANK: made in mild steel outside painted. There is no need
of any anti-corrosion treatment due to the fact that the buffer is in a
closed circuit without any adding air.
• DHW STORAGE: 316L stainless steel corrugated pipe, suitable
drinkable water according to D.M. n. 174 dated 06.04.04.

HEAT EXCHANGERS:
2 fixed heat exchangers.

TECHNICAL DESCRIPTION
Multi-heat Energy tanks EcoCombi 3 are used in units with a typically
discontinuous energy source for double use: heating system and
domestic hot water.
• Heating system with a biomass generator as energy source,
combining the possibility to produce domestic hot water. In such
case, storage heating volume allows the generator to regularly work,
limiting number of stops due to the inadequate energy request of
the heating system. Moreover, it limits the emission of smoke and
creation of corrosive condensate (smokes side).
• In this system, the high potentiality of the Eco Combi allows to
obtain a good DHW production, even if temperatures of the primary
system are not so high (e.g. using heating pumps as primary source
and solar source as support).
The particular shape of the corrugated pipe is avoiding any problem
relating to the DHW storage (less, stagnation, bacterium, etc.) and
ensure high heating exchange performances.

INSULATION
High thermal insulation with ecological polyurethane hard foam.
