  • Central Heating Pump Speed Setting

    In theory, the most efficient way to set up a central heating system is so that there's an 11 or 12 degree difference in the temperature of the water leaving the boiler, and the water returning to the boiler from the radiators. It may not always be possible to achieve this in practice.Learn More

  • Troubleshooting a Circulator Pump | DoItYourself.com

    Aug 23, 2018 · A boiler's circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.Learn More
