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.
