G3 Qualifed Unvented Hot Water Cylinder Specialists

An unvented hot water cylinder is a type of cylinder that stores hot water and delivers it directly from the mains water supply, without the need for a separate cold water storage tank. Because the system is sealed, it allows for higher water pressure at taps and showers, faster heating times, and more flexibility in installation.

Unvented cylinders are typically heated either by an immersion heater (direct) or via an external heat source such as a boiler, heat pump, or solar thermal system (indirect).

In summary:

• Delivers water from mains supply

• Does not require a separate cold water tank

• Allows for stronger water pressure and quicker heating times

• Can be heated using immersion or external heat sources
