Your Common Unvented Cylinder Questions Answered
Installing an unvented hot water cylinder typically takes between one and two days, depending on the complexity of the installation and whether significant pipework modifications are required. If the existing installation is a gravity-fed system with a header tank in the loft, additional work is needed to remove the tank, cap the redundant pipework, and connect the new cylinder to the mains supply. Our G3-qualified engineers plan every installation in full detail and provide a written quote covering all aspects of the work before a start date is agreed.
The correct cylinder size depends on the number of bathrooms in your property and the typical simultaneous demand for hot water. As a general guide, a 150-litre cylinder suits a one to two-bedroom property with a single bathroom; a 200-250-litre cylinder is appropriate for three to four bedrooms with two bathrooms; and larger properties with three or more bathrooms typically require 300 litres or more. Our approved engineers size your cylinder correctly based on a full assessment of your property and usage patterns, ensuring you always have adequate hot water without oversizing unnecessarily.
An unvented hot water cylinder is a sealed, pressurised hot water storage system connected directly to the mains cold water supply. Unlike traditional vented systems, it does not require a cold water tank in the loft, delivers mains-pressure hot water to every tap and shower simultaneously, and is generally more efficient. An unvented cylinder is a great option if you want improved water pressure, have multiple bathrooms, or are replacing an old gravity-fed system. Installation must be carried out by a qualified engineer holding an Unvented Hot Water qualification.
Yes, an unvented hot water cylinder should be serviced annually by a qualified engineer holding the G3 Unvented Hot Water qualification. During the service, the engineer inspects and tests all safety devices including the temperature and pressure relief valve, the expansion vessel, and the thermostat. Failure to carry out annual servicing can invalidate the manufacturer warranty and, more importantly, allows safety-critical components to degrade over time. An untested temperature and pressure relief valve that fails to operate correctly in a fault situation is a serious safety risk.
