Buy unvented hot water cylinders

Unvented cylinders provide high-pressure hot water by heating it directly from the mains supply. This differs from traditional vented hot water cylinders, which branch and heat water from a tank in the loft and use gravity to provide water flow throughout the property. Because unvented hot water cylinders don't require a storage tank and don't require gravity to function, they're ideal for homes with limited space and can be installed almost anywhere. 
We stock a wide range of unvented cylinders from leading manufacturers, including Albion, Gledhill and Heatrae Sadia. Find an unvented hot water cylinder in our collection and take advantage of free UK delivery on orders over £75. If it suits you better, you can simply Click & Collect your order from your nearest branch.

What types of unvented cylinders are available?

There are two main types to choose from:
  • Direct unvented hot water cylinders: This type uses electric immersion to heat the cylinder's water from inside the tank.
  • Indirect unvented hot water cylinders: This type pumps hot water from an external boiler through the cylinder's coil to indirectly heat the cylinder's water.
However, we do offer some additional options, including pre-plumbed and heat pump models. Use the search filters on the side of the page to find the type you're looking for more quickly.
