Description
The Megaflo Eco Slimline Direct 200L Unvented Cylinder (7034086) is a compact mains-pressure hot water storage solution designed for homes where a standard-width cylinder may not fit. With a slimline 491mm diameter and 200-litre nominal capacity, it provides substantial hot water storage while maintaining a narrow footprint.
Designed for direct electric heating, the cylinder features 2 × 3kW titanium immersion elements rated at 240V, providing a total installed immersion capacity of 6kW. Its 50mm CFC-free polyurethane foam insulation helps reduce standing heat loss, while the internal floating baffle eliminates the need for a separate external expansion vessel. The cylinder is factory-fitted with a T&P valve, 3 bar PRV, tundish and unvented kit.
