An unvented cylinder is a water heating system that stores hot water at high pressure and supplies it directly to your taps, showers, and other outlets without the need for a cold water storage tank. This results in better water pressure and a more efficient system overall.

An unvented cylinder works by taking cold water directly from the mains supply, heating it either via an immersion heater or through your central heating system, and storing the hot water under pressure. When a tap or shower is opened, hot water is supplied at mains pressure, offering powerful showers and fast filling baths.

• Better water pressure: You get improved flow rates at all outlets.
• No need for a cold water tank: Ideal for homes with limited loft space.
• Reliable hot water supply: Hot water can be used simultaneously at multiple outlets without loss of pressure.
• Space-saving: Frees up attic space compared to traditional vented systems.

No, planning permission is generally not required for installing an unvented cylinder. However, building regulations apply, and the installation must be carried out by a qualified engineer (such as us!) with the necessary certification.

Yes, unvented cylinders are flexible in terms of location, as they don’t require a cold water storage tank. They can be installed in basements, cupboards, or utility rooms, as long as there’s adequate space and ventilation.

Unvented cylinders should be serviced annually to ensure they are operating safely and efficiently. Regular servicing includes checking the pressure, safety valves, and ensuring all components are in good working order. Contact us for a service today.
