1.1.2 Introduction
HITACHI proudly announces the newest complete range of air-to-water heat pumps in its award-winning YUTAKI range.
YUTAKI units produce heating and domestic hot water like any oil or gas boiler, but transforming renewable energy from the outside
air into heat. Air to water heat pumps extract the free energy present in the air, which is enough to heat a home up to a comfortable
temperature, even on the coldest winter day. Every kW of electricity used to power the heat pump can yield up to more than 5 kW of
energy for heating; this provides savings of up to 80% on heating expenses compared to a traditional fossil fuel boiler.
The new YUTAKI series, based on state-of-the-art technology, does not only achieve an outstanding performance in space heating
but also provides domestic hot water with high efciency. Additionally, cooling operation for summer can also be provided installing
the dedicated “Cooling kit” accessory of HITACHI.
The system is simple to control; its new user controller (PC-ARFHE) improves the acclaimed and successful design used with the
existing LCD controller and provides a great deal of new functions like: wizard start-up conguration, auto cool/heat, improved timer,
etc.
1.1.2.1 Overview of YUTAKI system
The wide range of YUTAKI products is basically divided in two types of system:
• Split system
• Monobloc system
Split system - YUTAKI S, YUTAKI S COMBI, YUTAKI S80
It consists of one outdoor unit and one indoor unit. The outdoor unit extracts the heat present in the air, increases its refrigerant
temperature and transmits it to the water circuit using the plate heat exchanger of the indoor unit where the heat is taken to radiators
(fan-coils), underoor heating components or both (2nd temperature area).
Three types of indoor unit can be used in heating split systems:
YUTAKI S
The indoor unit of YUTAKI S is designed for space heating, in wall-mounted installation. It is convenient for new installations with low
capacity requirements (Well isolated installations, high efciency radiators...).
YUTAKI S COMBI
The indoor unit of YUTAKI S COMBI is conceived as a oor standing unit. It is prepared for heating operation as well as for domestic
hot water production. For this purpose, it has a built-in domestic hot water tank available in two sizes (200 or 260 L). In line with
YUTAKI S units, it meets the needs of installations with low capacity requirements.
Furthermore, special YUTAKI S COMBI models have been designed with a specic solar tank for the use of solar panels.

GENERAL INFORMATION
YUTAKI S80
The YUTAKI S80 is a standalone indoor unit that generates hot water up to 80ºC; the hottest water temperature in the domestic
heating market using renewable energy.
The extra innovation in the YUTAKI S80 lies in that it has two compressors, working in a smart cascade system, with two refrigerant
cycles (R-410A and R-134a). To maximize seasonal efciency, the second refrigerant cycle is only operated as a booster, when very
high water temperature is required - the rest of the time, only one cycle is used.
The YUTAKI S80 is ideal for existing properties, in particular older installations where high water supply temperatures may be
required to keep the house warm – as well as for new buildings. It is designed for the replacement of boilers, offering heating and
sanitary hot water all year round, without boiler back-up.
Two different models have been designed for different purposes: one model for space heating only and the other one for space
heating as well as for DHW operation. For DHW operation (optional), HITACHI offers two specic YUTAKI S80 DHW tanks
(DHWS200S-2.7H2E and DHWS260S-2.7H2E) which may be placed on top of the indoor unit or besides it, as an integrated unit to
provide high-temperature domestic hot water enjoying the benets of the high efciency of the heat pump.
Monobloc system - YUTAKI M
YUTAKI M is a monobloc air to water heat pump system, composed by only an special outdoor unit, which carries out the function of
an air-to-water heat pump. This results in an excellent solution when installation space available is limited.
YUTAKI M is designed to be installed outdoors, in any kind of dwelling (house, apartment, villa,…), whether in a new construction or
in an existing building. Installation work is greatly simplied thanks to the lack of refrigerant piping connections.
1.1.2.2 Summary of operations
Space heating
YUTAKI units are factory-supplied ready for space heating operation. Different heating installation congurations can be selected
providing a comfortable atmosphere all year long even in the coldest climates:
• Mono-valent system
The air to water heat pump is sized to provide 100% of the heating requirements on the coldest day the year.
• Mono-energy system
This is the most popular conguration. The air to water heat pump is sized to provide 80% of the heating requirements on the
coldest days of the year. An auxiliary electric heater is used to provide the additional heating required on cold days. This option
usually results in an ideal balance between installation costs and future energy consumption, as proven by its popularity in colder
climates than ours, such as Sweden and Norway.
• Alternating Bi-valent system
For installations with an existing heating system by boiler, and when is needed to heat the supplied water temperature to the
circuit up to high temperatures (80ºC), the boiler can be congured to alternate with the air to water heat pump.
Selecting the different conguration types it is possible to adapt the system to all customer requirements, providing a wide
application range from the simplest conguration to complete conguration: Radiator, heating oor or both (2nd temperature area).
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, 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.

GENERAL INFORMATION
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.
