Is it the Right Choice for You? We Think so!
Hot water cylinders are continually increasing in popularity and can now be found in most homes across the UK. They are commonly used to ensure that a copious amount of stored hot water is available on demand for a multitude of domestic uses. Unvented cylinders are connected directly to the mains water system so there is no cold water tank, which means they offer high water flow rates to provide higher water pressure for showers and baths.
An unvented cylinder is heated by either immersion heaters (a direct model) or by a heat source located outside the vessel such as a boiler or wet solar system (an indirect model).
Unlike vented cylinders, there isn’t a vent pipe or tank to cope with excess water as it heats and expands. To remedy this unvented cylinders have inbuilt safety features like an expansion unit at the top or an air bubble that is inserted at installation.
The installation of an unvented cylinder is considerably less hassle as it can be placed anywhere in your home and, with no water tank needed, doesn’t take up as much physical space.
No need for a water tank so the system takes up less space, giving you flexibility with where to install it.
Tend to provide stronger water pressure (depending on the strength of the mains).
No need for a tank of water that could freeze in winter or be contaminated.
