Why Choose the Boiler-M8 RS25/6EAY-130?
The Boiler-M8 RS25/6EAY-130 is designed for efficient, reliable circulation in modern heating systems. Its A-rated efficiency and iPWM control help reduce unnecessary energy use, while the 6m head performance makes it suitable for larger domestic circuits and heavier heating loads.
With 130mm spacing and 1½" BSP connections, this pump is a practical retrofit option for many existing heating pump installations. The cast iron body supports long-term durability, while the included cable, connector and documentation help simplify installation and commissioning.
Please note: always check existing pump spacing, connection size, wiring requirements, control compatibility and system design before ordering. Circulation pumps should be installed by a suitably qualified heating engineer or competent electrical professional. The system should be flushed, vented and commissioned correctly after installation.
