Increased tanks RWH-4.0NFWE + RAS-4WHNPE

Hitachi air-to-water heat pump YUTAKI S80 RAS-4WHNPE/RWH-4.0NFWE 11.6 kW

The Yutaki S80 heat pump can work in combination with underfloor heating and or radiators. The device also enables the preparation of hot sanitary water, as it is compatible with all models of water heaters. The heat pump can reach up to 80 ° C without the help of an auxiliary electric heater, even if the outside temperature drops below -20 ° C. High-temperature heat pump series Hitachi Yutaki S80 is the best solution for the renovation of existing heating systems. It is compatible with existing systems and provides the main types of heating and hot water (DHW).

Smart cascade technology
The Yutaki S80 heat pump uses two refrigerants, R410A and R134A. Smart cascade technology allows the unit to automatically set its operating parameters as required by heating. When the need for heating is lower, R410A refrigerant is used, and when the need for heating is higher, R134A refrigerant is activated.

Different configurations for each setting
Yutaki are available in two versions: a mounting unit in combination with a standard domestic hot water boiler or a mounting unit with an original water heater – a compact version. There are also two versions of the hot water heater (200 and 260 liters), which can be installed above or next to the indoor unit.

Always clean water
A stainless steel filter is installed in the boiler, which limits the formation of bacteria, even when water stays in the boiler for a long time, in cases of prolonged absence.

Smart management
The heat pump has a controller that centralizes all applications without the need for external components. It also includes an LCD remote control, which allows you to set the weekly schedule of heating and cooling and domestic hot water, the inclusion of energy saving mode for the water pump and many other functions. The controller is compatible with a wireless thermostat. The pump has a 3 phase power supply.
