Our Expert's Opinion
"Definitely the brand leader, and it has built-in expansion. You may want to also consider some of the cheaper ranges."Heatrae Sadia Megaflo Eco Slimline 100i Indirect Unvented Cylinder
The Megaflo Eco Slimline 100i is a 100 litre indirect unvented hot water cylinder, heated by your boiler through an internal coil: a compact version of the Megaflo Eco for homes where a standard size cylinder will not fit. At just 491mm in diameter it is taller and slimmer than a standard cylinder, giving mains pressure hot water to every outlet.
Why choose the Slimline
The internal expansion system means there is no separate expansion vessel to find room for. A 3kW immersion heater is fitted as a backup, and a wiring centre and 22mm 2 port motorised valve are supplied for the boiler connection.
Warranty
Heatrae Sadia's Megaflo warranty covers the stainless steel inner tank against corrosion for 30 years in domestic properties and all other components for 2 years, provided the cylinder is registered with Heatrae Sadia within 60 days of installation and serviced annually.

- 22mm male connections, 491mm diameter
- Heatrae Sadia product code: 7034087
