Frequently Asked Questions
What is a Megaflo system?
An Unvented Cylinder Megaflo is a hot water storage system that utilises mains water pressure to deliver hot water with good flow rates and pressure throughout a property. It can be heated directly by immersion heaters or indirectly by a heat source such as a boiler.
Do I need a Megaflo?
The choice is entirely up to you. Megaflo systems fill baths faster, give more powerful showers and provide a higher level of hot water than traditional boilers.
Megaflow systems offer great flexibility and can be installed almost anywhere within a property – and even come without the need for a water storage tank! They provide mains pressure hot water for better flow rates and pressure.
How do I know my Megaflo is broken?
• Problem with the expansion valve, pressure reduction valve or pressure and temperature relief valve
• Low water flow
• Problem with the high-level cutout or thermostat
• A leaking cylinder
• The RCD or electric breaker keeps tripping
• The tundish is filled with cold water
How long does it take to install an Unvented Hot Water Cylinder Megaflo?
