Haier GT R290 8 kW Monobloc Air Source Heat Pump - Single Phase

The Haier GT R290 8 kW (ref. AW082MUGHA) is a high-performance monobloc air-to-water heat pump that combines efficiency, sustainability, and ease of installation. Thanks to its use of natural refrigerant R290 and DC Inverter Twin Rotary technology, it achieves water temperatures up to 80 °C without auxiliary resistance and provides stable thermal comfort even at outdoor temperatures as low as –25 °C. Its monobloc design simplifies installation and reduces the required space, making it ideal for homes and light commercial applications.

Sizing Guide

The selection should be based on the thermal load of the building. As a guideline, 8 kW can cover approximately:

• Well-insulated buildings (30–40 W/m²): 200–260 m²
• Medium insulation (50–60 W/m²): 130–160 m²
• Poor insulation (80–100 W/m²): 80–100 m²

Indicative values; always confirm by performing a load calculation according to climate, emitter type, and insulation level.
