Everflo Stainless Slim-Fit Direct Unvented Hot Water Storage Cylinder & Kit
The Everflo Slim-Fit Direct Unvented Cylinder is purpose-built for homes where space is limited, especially in areas with restricted width but plenty of vertical room. Its slim, tall design makes it ideal for cupboards, narrow utility spaces, or installations where standard cylinders simply won’t fit.
Designed for properties that rely on electricity rather than mains gas, the Slim-Fit Direct range uses durable Incoloy immersion heaters to heat water efficiently. These heaters can also be paired with low-tariff electricity, helping keep running costs down. Made from robust duplex stainless steel and available in 150L, 180L and 210L capacities, this range is perfectly suited to homes with multiple bathrooms or higher hot water demand.
