Heat Pump Radiators

Radiators for Heat Pumps — Low Temperature Optimised

Heat pumps run at lower flow temperatures (35-55°C) compared to gas boilers (70°C), which means standard radiators may not deliver enough heat. Our heat pump compatible radiators are selected for high output at low temperatures, ensuring your rooms stay warm without cranking up your heat pump's flow temperature.

Key Selection Criteria

• Delta T30 output — Heat pump radiators are rated at ΔT30 (flow 45°C / return 40°C). This is approximately 52% of the standard ΔT50 rating. Always check the ΔT30 figure, not ΔT50.
• Aluminium radiators — Our top recommendation for heat pumps. Aluminium heats up faster and responds better to the lower water temperatures that heat pumps produce.
• Oversizing — As a rule of thumb, you need roughly double the ΔT50 BTU rating to achieve adequate heating at heat pump temperatures.

Use our BTU Calculator to find your room's heat requirement, then select radiators with sufficient ΔT30 output. See our complete heat pump radiator guide for detailed sizing advice. Free UK delivery.
