3. Product description

The LATENTO XXL is an unpressurised stratified solar storage tank that was devel-
oped for employment in a one-/two-family house. Apartment houses (multi-family
houses) can be supplied via several LATENTO XXL Tichelmann-system connected
units.
The LATENTO XXL has the capacity of storing solar energy (=free energy). The in-
sulation of the storage tank has been designed such that accumulated energy can
be stored over several days. Depending on power demand, this renders supply
possible that covers a spell of bad weather too.
In the case of insufficient solar energy, the LATENTO XXL, using other heat sources,
can be heated up to the temperature required to guarantee supply of sufficient hot
water, and during the heating period, of sufficient heating power.
The LATENTO all-inclusive regulation allowing control of the entire heating system,
enables adaptation to your individual requirements. Thereby, the conventional
energy fed into the LATENTO XXL must be subtracted from the possible charg-
ing capacity for the solar charge (cf. the Chapter Adaptation to your individual
Requirements on page 32).
Latent Material
The LATENTO XXL is operated with latent material. The latent material melts at a
temperature of approx. 65 °C. While doing so, it absorbs heat energy without the
temperature changing in the storage tank at all. So energy can be stored without
major heat-losses – as it is the case at temperature rise, for instance. When the
storage tank cools below 65 °C, the latent material will resolidify dissipating the
stored energy to the storage water.
Moreover, the latent material prevents evaporation of the storage water. This will
minimize losses of water and energy. For that reason the LATENTO XXL has been
factory filled with a small quantity of latent material. The latent material does not
pose any health hazard.
