Megaflo Boilers and Boiler Repairs R Us


Over 20+ years experience with Megaflo Boilers

The Megaflo boiler is renowned for its high performance and reliability, largely due to its advanced hot water cylinder design. Specifically, the Megaflo hot water cylinder features an internal air cushion that accommodates hot water expansion, ensuring consistent high water pressure. The expansion vessel is a crucial component that helps manage the pressure within the system, ensuring safe and efficient operation. This makes it a preferred choice for both residential and commercial properties, providing efficient and reliable hot water solutions.


London Specialists


Megaflo systems are a sophisticated type of unvented hot water system designed to deliver high-pressure hot water directly from the mains cold water supply. Unlike traditional systems that rely on a cold water storage tank, Megaflo systems eliminate the need for such a tank, ensuring a consistent and powerful water supply.

At the heart of these systems is the Megaflo hot water cylinder, which stores and supplies hot water efficiently. The system also includes an immersion heater, which heats the water, and a pressure reducing valve, which ensures the water pressure remains at a safe and consistent level. Together, these components work harmoniously to provide a reliable and efficient hot water supply, making Megaflo systems an ideal choice for modern homes and businesses.

  • Check the Air Gap: Regularly inspect the air gap to ensure it is clear and free from debris. This helps maintain the system’s efficiency and prevents potential blockages.
  • Inspect the Immersion Heater: Look for signs of wear and tear on the immersion heater and replace it if necessary. A well-functioning immersion heater is vital for consistent hot water supply.
  • Check the Pressure Reducing Valve: Ensure the pressure reducing valve is functioning correctly to maintain safe and consistent water pressure.
  • Inspect the Hot Water Cylinder: Regularly check the hot water cylinder for signs of leaks or corrosion. If any issues are found, replace the cylinder to prevent further damage.
  • Install a Water Filter: Consider installing a water filter to protect your system from limescale and debris, which can cause blockages and reduce efficiency.

By following these preventative maintenance tips, you can help prevent common issues with your Megaflo system and ensure it continues to provide a reliable hot water supply. Regular maintenance not only enhances the performance of your system but also extends its lifespan, ensuring you get the most out of your investment.

To ensure the safe and effective maintenance of your Megaflo hot water cylinder, it is crucial to turn off the mains cold water supply. This step is essential when servicing the cylinder, as it allows you to safely recharge the air bubble inside. By turning off the cold water supply, you can prevent any potential water damage and ensure that the maintenance process is carried out smoothly. Ensure the expansion vessel is functioning correctly to manage system pressure and prevent potential issues. Always remember to follow this important step to maintain the efficiency and longevity of your Megaflo hot water cylinder.
