Energy Efficiency
This value greatly depends on the storage
temperature and installation diagram.
Diagram B is the scheme with maximum
energy savings. In this case, if the heat ex-
changer is placed at some distance from
the drain point, a certain loss of heat from
the pipes during the transitory phase
must be taken into consideration (mostly
in case of very short or discontinuous use

As for diagram A, the recovery efficiency
mainly depends on the hot storage tem-
perature (boiler). Localized interventions
on single use are the simplest to perform
and are usually tied to Diagram A, there-
fore, they have higher energy efficiency in
the case of medium – high storage tem-
perature. Diagram A, if built into the ap-
pliance (for example a shower), presents
the advantage of a very short connection
