Haier GT R290 12 kW Monobloc Air Source Heat Pump - Three Phase

The Haier GT R290 12 kW Three-Phase (ref. AW12NMXGHA) is a high-performance monobloc air-to-water heat pump designed to provide heating, cooling, and domestic hot water (DHW) with maximum reliability. Its DC Inverter Twin Rotary technology and use of natural refrigerant R290 ensure A+++ efficiency and supply temperatures up to 80 °C without auxiliary heating, even at outdoor temperatures as low as –25 °C. The three-phase 380–415 V configuration provides stable power for installations with high thermal demand.

Key Features

• Energy class A+++ with SCOP 4.82 (35 °C) and 3.85 (55 °C).
• Water temperature up to 80 °C without electric backup (> –15 °C outdoor).
• Wide operating range: heating –25 °C ~ 35 °C / cooling up to 48 °C.
• 2-zone control with independent temperature regulation.

Indicative Sizing

The power should be selected according to the building’s thermal load. As a reference, 12 kW three-phase can cover approximately:

• Well-insulated buildings (30–40 W/m²): 300–400 m²
• Medium insulation (50–60 W/m²): 200–240 m²
• Poor insulation (80–100 W/m²): 120–150 m²

Indicative values; always confirm by calculating thermal loads according to climate, emitter type, and insulation level.
