Product Information

Heatrae Sadia Megaflo Eco 300DDDD Unvented Cylinder

The Heatrae Sadia Megaflo Eco 300DDDD is a 300-litre direct unvented hot water cylinder designed to provide a generous supply of domestic hot water for properties with higher demand. As a direct cylinder, it heats the stored water electrically rather than relying on a separate boiler. With its large storage capacity and powerful 4 x 3kW heating elements, the Megaflo Eco 300DDDD is designed to provide dependable hot water performance. Its polyurethane insulation also helps retain heat within the cylinder, supporting efficient operation.

300-Litre Hot Water Capacity

With a 300-litre capacity, this cylinder provides substantial hot water storage for larger households and properties where demand for hot water is higher. The generous capacity helps ensure there is a good supply available for everyday activities such as bathing, showering and washing. The cylinder has a total electrical power rating of 12kW, provided by four 3kW heating elements, with a stated recovery time of approximately 73 minutes.

Direct Electric Heating

The Megaflo Eco 300DDDD is a direct unvented cylinder, so it does not need to be connected to a boiler to heat the stored water. Instead, the cylinder uses its integrated electrical heating elements to generate hot water directly. This makes it a practical choice for installations where an electrically heated hot water cylinder is required, while the unvented design provides a modern approach to domestic hot water storage.

Efficient Insulation

The cylinder uses polyurethane insulation to help reduce heat loss and retain the temperature of the stored water. This insulation contributes to the cylinder's overall energy performance and helps maintain hot water between heating cycles.

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.
