Haier GT R290 4 kW Monobloc Air Source Heat Pump - Single Phase

The Haier GT R290 4 kW monobloc air-to-water heat pump (reference AW042MUGHA) is a next-generation all-in-one solution that combines sustainability, power, and a compact design. Equipped with natural refrigerant R290, this unit provides heating, cooling, and domestic hot water (DHW) with high energy efficiency and low environmental impact.

Key Features

• A+++ Efficiency according to ErP, with a SCOP of 5.10 at 35°C and 3.85 at 55°C.
• Wide operating range: functions normally even at outdoor temperatures as low as –25°C.
• Outlet water temperature up to 80°C without auxiliary heater when outdoor temperature is above –15°C.
• Intelligent dual-zone control for independent heating or cooling circuits.
• Automatic mode that adjusts operation according to room temperature.
• Configurable climate curves to optimize comfort and efficiency based on outdoor temperature.
• Integrated DHW and solar control for managing storage tanks and solar thermal energy.
• Smart Grid Ready for integration with smart grids and energy consumption management.

Technical Data Summary

• Model: AW042MUGHA
• Nominal thermal power: 4 kW
• System type: Air-to-water monobloc
• Refrigerant: R290 (propane)
• Power supply: Single-phase 220–240 V

Indicative Sizing

Selection should be based on the building’s thermal load. As a reference, 4 kW can cover approximately:

• Very well insulated buildings (30–40 W/m²): 100–130 m²
• Medium insulated buildings (50–60 W/m²): 65–80 m²
• Poorly insulated buildings (80–100 W/m²): 40–50 m²

Indicative values; always confirm with load calculations (climate, emitters, and supply temperature).
