Shop Gledhill Unvented Cylinders (Mains Pressure Hot Water)

Gledhill unvented cylinders provide mains pressure hot water for strong shower performance and fast delivery to taps throughout the home. They're a popular choice for modern properties and households with higher hot water demand, especially where multiple bathrooms are in use at the same time. At TDL Online you can browse the full range of Gledhill unvented cylinders below, including stainless steel options designed for compact installs, renewable heating systems and high-performance hot water storage.

Popular Unvented Ranges

Gledhill's best-known unvented ranges include Stainless ES, Stainless Platinum, StainlessLite Plus and Stainless Pro. Choose from indirect models (boiler-fed via a coil) or direct models (immersion heated), with options such as slimline and horizontal cylinders where installation space is limited.

Choosing the Right Gledhill Unvented Cylinder

To choose the correct Gledhill unvented cylinder, start by confirming your heat source and installation space:

  • Indirect cylinders are the most common option for boiler-fed homes, using a coil to heat stored hot water
  • Direct cylinders are immersion heated and are ideal for all-electric setups or where no boiler coil is required
  • Slimline cylinders are designed for tight airing cupboards with limited diameter
  • Horizontal cylinders are suitable where vertical height is restricted, such as loft installs or low headroom areas
  • Heat pump and solar cylinders are designed to maximise efficiency when paired with renewable energy systems

If you're unsure which type you need, your installer can quickly confirm the correct specification based on your heating system and hot water demand.
