    Improved Flow Rates: Unvented systems typically provide better flow rates compared to vented systems, ensuring a stronger and more consistent flow of hot water from taps and showers.

    Flexible Installation: Unvented cylinders can be sited anywhere in the property as they do not rely on gravity for water distribution. This allows for greater flexibility in installation and design.

    Quiet Operation: With no cold water tank filling up, unvented systems operate quietly, providing a more peaceful environment in your home.

    Reduced Risk of Freezing Pipes: The absence of a cold water tank in the loft reduces the risk of pipes freezing in cold weather, minimizing the chances of damage and inconvenience.

    High Efficiency: Unvented cylinders are often highly efficient, as they can be easily integrated with modern heating systems and renewable energy sources, such as solar panels or heat pumps.

    How does an unvented hot water cylinder work?

    The hot water cylinder is directly fed from the incoming mains water supply, which keeps the water under constant pressure and ready to be used. To heat the water within an unvented hot water system there are two different methods.

    In a directly heated model, the cold mains water is heated by an immersion heater built into the cylinder. Conversely, in an indirectly heated model, an external source such as a gas boiler or solar panels heats the water.

    When hot water is required at a tap or appliance, the pressure from the incoming cold water pushes the hot water out of the cylinder. This hot water is then carried through an outlet pipe to its intended destination.

    These systems are equipped with pressure and temperature relief equipments. The aim of these tools is to vent the cylinder in case it overheats or in the event that the internal pressure gets too great. This safety feature is designed to minimise the chances of failing equipments or, in serious cases, the risk of explosion.

    Do unvented hot water cylinders need servicing?

    It is essential to keep your system serviced and well-maintained. Regular servicing can prolong the lifespan of your cylinder and ensure that it is working efficiently and without troubles. It can also ensure that it is safe to operate and pose no threat to your safety. Your system should be checked once a year by a qualified technician.
