Grant UK Heat Pump FAQs

Grant UK is highly regarded by installers, particularly for retrofit installations. As a specialist heating company (rather than a huge conglomerate), they offer focused expertise and strong UK-based support. Their products are specifically designed for our climate.

The G1 is Grant's performance monitoring platform that tracks your heat pump's efficiency, energy consumption, and system health. Both you and your installer can access the data, making it easier to optimise performance and diagnose any issues remotely.

Grant is particularly strong for oil-to-heat-pump conversions, which is their heritage market. They understand the challenges of off-gas properties and design their systems accordingly. Many of their installations replace oil boilers.

Grant Aerona3 models achieve up to 65°C flow temperature, which is sufficient for most existing radiator systems. For optimal efficiency, we'd recommend running at 35–45°C with correctly sized radiators after a heat loss survey.
