Discounted Heating stocks a range of hot water cylinders that’s been expertly sourced from some of the leading names in plumbing.

With a selection of vented and unvented cylinders from highly respected brands including Heatrae and Vaillant, you can find the ideal model to complete any trade plumbing installation.

These cylinders store, heat, and distribute water around a home, and – often alongside expansion vessels and immersion heaters – are a key component in many domestic heating installations nationwide. Because of their importance, we choose all of our cylinders for their quality and reliability – so that a great low price doesn’t have to mean a compromise on excellence.

Unvented Cylinders are connected directly to the water mains and can therefore provide hot water at mains water pressure.

Vented Cylinders are connected to water tanks usually in the loft and form part of a complete heating system.
