Combi Boiler Or Heat Pump Ready

HeatBoost radiators are compatible with existing heating systems and offer significantly more heat than traditional radiators. Installation is straightforward, typically involving just replacing the old radiator, and they require an electrical connection which can be linked from an existing circuit or plug socket.

These radiators can lead to reduced boiler usage, potentially lowering your heating bills—consult your boiler provider. Operating efficiently at just 35 degrees water temperature, HeatBoost radiators enhance system efficiency and cut running costs.

With only up to 1 litre of water internally—ten times less than steel radiators—they heat up more quickly and eliminate the need for large, bulky radiators. A single HeatBoost 550LM radiator can replace two K3 1400mm radiators, saving space and reducing installation time.

Radiator FAQ

How do dual cool radiators work?

Water warmed or chilled by your air source heat pump flows through the radiator’s coil. An integrated fan then disperses the heated or cooled air across the room, ensuring effective temperature regulation.

Are heat & cool radiators compatible with heat pumps?

Most air source heat pumps and combi boilers work seamlessly with Dual Cool Radiators. Consult our experts for compatibility confirmation. 

Do I they work with underfloor heating?

HeatBoost radiators give out extraordinary amounts of heat from flow rates as low as 35 degrees, so they are perfect to work alongside heating systems planning to use lower temperature heating.
