Domestic hot water production
YUTAKI models also give the option of domestic hot water production, allowing the user to benet from the heat pump’s high
efciency and achieve domestic hot water.
This is made possible by a domestic hot water tank. In case of YUTAKI S COMBI, the domestic hot water tank is built in the indoor
unit. In YUTAKI S80, a specic DHW tank is designed for combination with the indoor unit. For YUTAKI S and YUTAKI M (R410A) /
YUTAKI M (R32), the Hitachi accessory “DHWT-(200/300)S-3.0H2E” can be used for the production of DHW.
An electric heater is incorporated inside the tank in order to allow an immediate heating of the domestic hot water in accordance with
the user’s needs.
Space cooling
YUTAKI units can also be operated in cooling operation The dedicated “Cooling kit” accessory has been designed for this purpose.
Combining the heating only models with these cooling kits, the reversible models become available. In this case, combination with
fan-coils, refreshing oor or both (2nd temperature area) can be applied.
Combination with solar panels
YUTAKI system can be combined with solar panels. The solar combination enables to heat up the DHW by means of the sun. The
solar combination is designed to transfer the heat from the solar panels (sun radiation) to the heat exchanger of DHW tank.
In case of YUTAKI S COMBI, a specic model with integrated tank for solar combination has been designed, as explained before.
Swimming pool water heating operation
For summer session period, YUTAKI system can be used to heat the water temperature of swimming pools up to a value between
24 and 33ºC.
