The three-phase 10 kW version (400 V) of the Chofu R290 range for a standard three-phase supply – efficient and robust for single-family homes and larger properties. With a current draw of just 8 A, it is particularly suited to installations with existing three-phase power. As a monoblock it heats and cools using the natural refrigerant propane (R290, GWP 3). With COP 4.72 (A7/W35), SCOP 4.6 and energy class A+++ (35 °C) it runs highly efficiently; flow temperatures up to 75 °C allow operation with radiators, and operation is reliable down to −25 °C.
