Air-to-Water Heat Pump Yutaki Combi S60 16kW 3ph

Description

Air-to-Water Heat Pump Hitachi Yutaki Combi S60 16 kW 3 phase

Complete and integrated system: enjoy twice the benefit with our two in one system with space heating and hot water supplied from one unit to ensure complete ease of installation and peace of mind.

High-performance heat pump technology keeps your home at a comfortable temperature even on the coldest days: down to -25c. At the same time, it reduces both domestic power use and CO2 emissions, and is compatible with solar panels.

Intuitive control from anywhere:
The built-in controller has an LCD display and is easy to programme, giving you total control over the system from your utility cupboard; it’s also compatible with wireless thermostats.

The Hi-Kumo app turns your smartphone into a programmable remote control where you can adjust and monitor your heating system from anywhere in the world.

The Yutaki S Combi can be installed in kitchens due to its small size and low noise level.
Integrating the DHW storage tank into the indoor unit frees up as much as 70% more room compared to a separate tank.

New Remote control included as standard
An intuitive interface that can handle two zones, and features an ambiance sensor to be used as a separate modular thermostat.

Easy to install and maintain
Compared to a system with separate tank, the Yutaki S Combi can be installed in less time and at a lower cost because:
- All water and refrigerant connections are aligned at the top.
- Most components are accessible from the front.
- Easy access to information from the LCD remote control without having to open the indoor unit.

Stainless steel tank with built-in element
The Yutaki S Combi range comes with an additional electrical heating element. In an emergency, you can activate the DHW BOOST function at the push of a button.
