Grant
The Grant Aerona3_User_Manual is a monobloc air-source heat pump range available in 6kW to 17kW outputs, utilizing R32 refrigerant and featuring integrated weather compensation.
The Grant Aerona3_User_Manual covers the range of monobloc air-source heat pumps designed for domestic heating and hot water. Available in four outputs—6kW, 10kW, 13kW, and 17kW—the series utilizes R32 refrigerant to provide efficient performance. These units feature weather compensation and automatic defrosting as standard. This guide covers the user instructions, operational controls, and maintenance requirements for the HPID6R32, HPID10R32, HPID13R32, and HPID17R32 models within the Aerona³ product family.

The Grant Aerona3_User_Manual range represents a series of monobloc air-source heat pumps engineered for the UK market. As monobloc units, the entire refrigerant circuit is contained within the outdoor housing, meaning no F-Gas qualification is required for the hydraulic connection to the heating system. The range is comprised of four distinct models: the HPID6R32 (6kW), HPID10R32 (10kW), HPID13R32 (13kW), and the high-output HPID17R32 (17kW). These ratings are calculated based on an outdoor air temperature of 7°C and a flow temperature of 35°C.
A key technical feature of the Aerona3_User_Manual is the use of R32 refrigerant. Compared to legacy R410A systems, R32 has a significantly lower Global Warming Potential (GWP), making it a more environmentally compliant choice for modern installations. The units are designed to operate efficiently across varying UK weather conditions, utilizing built-in weather compensation. This feature adjusts the flow temperature based on the external ambient temperature, ensuring the heat pump operates at its most efficient point while maintaining indoor comfort.
The control interface for the Aerona3_User_Manual often includes compatibility with the Greenbrook T205-C timer, allowing users to schedule heating cycles effectively. The system also features an automatic defrost function, which prevents ice build-up on the evaporator coils during cold periods, ensuring continuous operation even when temperatures drop.
Maintenance is a critical factor for long-term performance and warranty compliance. Grant specifies a 12-month service interval for the Aerona3_User_Manual range. During these annual checks, engineers typically inspect the hydraulic pressure, clean the filters, and verify the integrity of the evaporator fins. Because these are monobloc units, the primary focus for the heating engineer is the water-side components and the external unit's airflow.
For installers and homeowners, the Aerona3_User_Manual provides a scalable solution. The 6kW and 10kW models are frequently specified for well-insulated new builds or smaller retrofits, while the 13kW and 17kW variants provide the necessary capacity for larger detached properties with higher heat loss requirements. All models in the range are designed to work alongside compatible cylinders and controls to provide a complete low-carbon heating solution.
