As a direct cylinder, it heats the stored water electrically rather than relying on a separate boiler.\n\nWith 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.\n\n\u003ch3\u003e300-Litre Hot Water Capacity\u003c\/h3\u003e\n\nWith 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.\n\nThe cylinder has a total electrical power rating of 12kW, provided by four 3kW heating elements, with a stated recovery time of approximately 73 minutes.\n\n\u003ch3\u003eDirect Electric Heating\u003c\/h3\u003e\n\nThe 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.\n\nThis 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.\n\n\u003ch3\u003eEfficient Insulation\u003c\/h3\u003e\n\nThe 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.\n\n\u003ch3\u003eDimensions and Specifications\u003c\/h3\u003e\n\nThe Megaflo Eco 300DDDD measures 2053mm high, 579mm wide and 579mm deep, so suitable installation space should be checked before purchase.\n\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 300 litres\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2053mm\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 579mm\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 579mm\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 12,000W (4 x 3kW)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eRecovery time:\u003c\/strong\u003e approximately 73 minutes\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEnergy performance rating:\u003c\/strong\u003e C\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEmpty weight:\u003c\/strong\u003e 58kg\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFull weight:\u003c\/strong\u003e 339kg\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eHeater type:\u003c\/strong\u003e Cylinder\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e300-litre direct unvented hot water cylinder\u003c\/li\u003e \u003cli\u003eDirect electric heating – no boiler connection required for water heating\u003c\/li\u003e \u003cli\u003eFour integrated 3kW heating elements\u003c\/li\u003e \u003cli\u003eTotal electrical power of 12kW\u003c\/li\u003e \u003cli\u003ePolyurethane insulation for improved heat retention\u003c\/li\u003e \u003cli\u003eApproximately 73-minute recovery time\u003c\/li\u003e \u003cli\u003eEnergy performance rating C\u003c\/li\u003e \u003cli\u003eSuitable for properties with higher hot water requirements\u003c\/li\u003e \u003cli\u003eCompact footprint relative to its 300-litre capacity\u003c\/li\u003e \u003cli\u003e2-year warranty\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003eWhat is the capacity of the Megaflo Eco 300DDDD?\u003c\/h4\u003e\n\nThe Megaflo Eco 300DDDD has a 300-litre storage capacity, making it suitable for properties requiring a substantial supply of stored domestic hot water.\n\n\u003ch4\u003eDoes the Megaflo Eco 300DDDD need a boiler?\u003c\/h4\u003e\n\nNo. It is a direct unvented cylinder, meaning the stored water is heated electrically using its integrated heating elements rather than through a separate boiler.\n\n\u003ch4\u003eHow powerful is the Megaflo Eco 300DDDD?\u003c\/h4\u003e\n\nThe cylinder uses four 3kW heating elements, giving it a combined electrical power rating of 12kW.
