Heatrae Sadia Megaflo Eco Cylinders

Megaflo Eco is Heatrae Sadia's best-selling range of unvented hot water cylinders, from 70 to 300 litres. Most models use Megaflo's internal expansion system, so there is no separate expansion vessel to fit, and 60mm of insulation to keep the heat in. Every Megaflo Eco comes with a 30-year warranty on its stainless steel inner tank. Choose direct for electric heating or indirect to run from your boiler.

Direct or indirect?

  • Direct models (D, DD, DDD and DDDD) are heated by electric immersion heaters, so they suit homes without mains gas. Each D in the name is one heating element, and more elements mean faster recovery.
  • Indirect models (i) are heated through a coil by your system or heat-only boiler, with an immersion heater as back-up.

Other Megaflo Eco versions

  • Slimline: narrower cylinders for tight airing cupboards.
  • Solar: built to take heat from solar thermal panels, with your boiler or immersion heaters as back-up.
  • Solar PV Ready: direct and indirect cylinders designed to use surplus electricity from solar PV panels to heat your water.
