The Megaflo cylinder ranges
Megaflo Eco
The most popular section of the range. The Eco cylinders have an internal expansion system, which cuts the external pipework and means you do not need a separate expansion vessel at installation. Available from 70 to 300 litres, direct (with up to 4 heating elements) or indirect.
Megaflo Essential
The value range. Direct and indirect models from 170 to 300 litres keep Megaflo's internal expansion, so there is still no separate vessel to fit. The direct has two 3kW immersion heaters for homes off the gas grid; the indirect has a coil-in-coil heat exchanger and a 3kW back-up immersion. There is also an air source heat pump model from 210 to 300 litres, with a large surface area coil, a secondary return and a supplied expansion vessel.
Megaflo Eco Plus
Built for higher demand, with faster recovery than the Eco. 250 to 570 litres, direct or indirect, with a separate expansion vessel supplied, so it suits semi-commercial sites and larger households or estates.
Megaflo Eco SystemFit
All plumbing connections arrive pre-connected, colour coded and reachable from the front of the cylinder, which saves time on the fit. All SystemFit models are indirect, 125 to 300 litres.
Megaflo Eco SystemReady
The same capacity range as the SystemFit but built to run with a system boiler. High-grade duplex stainless steel with 60mm polyurethane insulation for heat retention.
Megaflo Eco Commercial
400 litres up to 2500, in direct, indirect and solar. High-performance coils and a choice of elements give up to 162kW of heat, so every model recovers in under an hour. The commercial models carry a 30 year warranty.
Megaflo Unvented Accessories
Kits, immersion heaters and gauges to suit the Megaflo range.
Megaflo Essential or Megaflo Eco?
Both are mains pressure stainless steel cylinders, and both use Megaflo's internal expansion on their direct and indirect models. The differences that matter:
- Warranty: 30 years on the Eco's inner tank, 20 years on the Essential's.
- Insulation: 60mm on the Eco, 50mm on the Essential.
- Sizes: the Eco starts at 70 litres; the Essential runs from 170 to 300 litres.
- Price: the Essential costs less, size for size.
Choose the Essential where budget matters most, and the Eco for a smaller cylinder or the longest tank warranty. Fitting a heat pump? Compare the Essential ASHP with our other heat pump cylinders.
