Most water supply systems are built on the principle of gravity. In such a setup, the pressure at the tap in your bathroom or kitchen is dependent on the height difference of the cold water tank and the highest outlet of your property, which is usually the shower on the top floor. With systems built on the gravity principle, you’ll notice an increase in the flow of water when the showerhead is held close low to the hot and cold supply pipes. The use of how water cylinder allows ignoring the gravity requirements ensuring even flow pressure at all points of the distribution system.

As the plumbing components built for use in gravity systems are not suitable for pressure systems, you need to have relevant education when carrying out hot water cylinder fitting. For example, unvented hot water cylinder installation will entail the need for changing the shower cartridge and valves on the water distribution pipes network in order to enable them to cope with the overall increased pressure in the system. Improperly selected cylinder components will put your property at the risk of damage due to the failure of the water heating unit. By turning to the services of experienced engineers for the cylinder fitting and maintenance, you invest in personal peace of mind and ensure the safety of your family.



  • Vented mains pressure.

The system uses a vent pipe that makes the cylinder react to the atmospheric pressure outside. The water is fed and kept in a storage tank until needed by the appliances in your property.

  • Unvented mains pressure.

The unvented cylinder system takes water directly from the mains, which ensures better flow. Special safety measures should be observed when installing such a hot water cylinder because the system is considered closed and the water can get overheated under pressure leading to an emergency.

Vented Mains Pressure Benefits

The vented hot water cylinder system is less complex when it comes to the installation procedure and cheaper in terms of maintenance. Such an option is more economical and reliable if the installation is entrusted to qualified engineers. You can rely on our expertise for installing, repairing and servicing vented hot water cylinders, fed from cold water storage tanks. We guarantee high-quality work performance and can provide new cylinders at reduced prices.


Unvented Mains Pressure Benefits

With unvented cylinders, the flow tends to be more consistent as the hot water is supplied at mains pressure. Such a system will allow you to enjoy your showers more, in addition to saving space in your premises because there is no need for a cold water storage tank. Unvented cylinders can be placed virtually anywhere, and they will still function effectively regardless of gravity. Such an option is more expensive compared to a vented cylinder, but many people are willing to spend money for the extra level of comfort.
