Product Information

Heatrae Sadia Megaflo Eco Slimline 150 Litre Indirect

The Heatrae Sadia Megaflo Eco Slimline 150 Litre Indirect Cylinder is designed to deliver dependable hot water performance while making the most of available installation space. Its slimline profile makes it particularly useful for tighter airing cupboards and installations where access can be challenging, including situations where the cylinder needs to pass through a loft hatch. The cylinder uses Heatrae Sadia's tried-and-tested internal floating baffle expansion system, removing the need for a separate expansion vessel. This helps save valuable space and can also make installation quicker and more straightforward.

Space-Saving Slimline Design

The Megaflo Eco Slimline has been designed to fit into areas where a conventional cylinder may be difficult to accommodate. Its 491mm width and 516mm depth provide a relatively compact footprint, while the 1622mm height makes use of available vertical space. In-line connections further help to keep the installation neat and space efficient, making the cylinder well suited to modern domestic hot water systems where available room is limited.

Efficient and Durable Construction

High-performance insulation helps reduce standing heat loss, with this model rated at 1.46kWh per 24 hours. This helps the cylinder retain stored hot water temperature and supports efficient operation. The cylinder is manufactured from high-grade duplex stainless steel, providing high corrosion resistance while maintaining a strong strength-to-weight ratio. This robust construction is designed to support long-term reliability, with the product carrying a 25-year guarantee.

Indirect Heating System

As an indirect unvented cylinder, the Megaflo Eco Slimline is designed to work with an external heat source, such as a compatible boiler or solar thermal system. It features a high-performance indirect coil and includes one 3kW immersion heater. The cylinder can provide a flow rate of up to 70 litres per minute at 3 bar, while its maximum operating pressure is rated at 16 bar.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
