Megaflo by Heatrae Sadia

The name 'Megaflo' is synonymous with innovation, quality and performance. These values lie at the heart of a product that we have developed by listening to the needs and expectations of our customers.

Megaflo has been part of Heatrae Sadia since 1993 and is the market leader in the unvented hot water cylinder sector, despite increasing competition; so much so that Megaflo is seen as the generic term for unvented water heating.
