A real alternative to traditional boilers

01. HOME HEATING AND HOT WATER

The system heats water up to 80°C, even with outdoor temperatures as low as -20°C. It provides heating via underfloor piping, radiators and fan coils, and is compatible with all models of water tank.

02. ENERGY-SAVING COMFORT

When you need less heating, the Yutaki S80’s intelligent cascade cycle automatically adjusts to ensure maximum comfort with minimal energy use.

03. ECO-FRIENDLY EFFICIENCY

The heat pump converts every kilowatt of electricity into 5kW of heating energy. Compared to traditional boilers, it reduces electricity bills by up to 60% and CO2 emissions by 50%.

04. USER-FRIENDLY CONTROLS

The controller with LCD display and thermostat is easy to programme, giving you total control over the system. For even more control, it’s also compatible with wireless thermostats.
