World Heat Cylinders manufactures a robust range of Duplex Stainless Steel Vented Hot Water Cylinders. These units offer a superior alternative to traditional copper vented cylinders, particularly recommended for installations in hard water areas where mains water can be more corrosive and prone to scale build-up. Our stainless steel vented cylinders combine durability with efficient performance, providing a reliable hot water solution for various domestic and small commercial applications.

Our Cylinders are engineered with several key advantages:

• Enhanced Durability in Hard Water Areas: Duplex stainless steel construction offers excellent resistance to corrosion and scale, significantly extending the lifespan of the cylinder compared to copper in aggressive water conditions.
• High-Performance Heating Coil: Each cylinder is equipped with a high-efficiency primary heating coil. This design ensures excellent heat transfer and rapid hot water recovery rates when connected to a conventional boiler (gas, oil, or electric).
• Superior Heat Retention: We utilise high-grade insulation to ensure that the stored hot water retains its heat energy for extended periods. This minimises standing heat losses and improves overall system efficiency.
• Insulation Options: Our stainless vented units are available with either traditional foam lagging insulation or a sleek, cased finish featuring high-density injection foam insulation for optimal thermal performance and a professional aesthetic.
• Versatile Applications: Suitable for gravity-fed hot water systems in properties with a cold water storage tank.
• Quality Manufacturing: Proudly manufactured in the UK to meet our stringent quality standards.
