Unvented Hot Water System FAQs
What is an unvented hot water system?
An unvented hot water system stores hot water in a sealed cylinder connected directly to the mains water supply. This can provide stronger water pressure at taps and showers without the need for a cold-water storage tank in the loft.
Do unvented hot water systems need specialist engineers?
Yes. Unvented cylinders include important pressure and temperature safety controls, so installation, servicing and repairs must be completed by an appropriately qualified engineer who understands the relevant Building Regulations.
Do unvented systems require regular servicing?
Yes. Annual servicing is generally recommended to check safety devices, valves, controls and system pressure. Regular maintenance can also identify developing faults and help the system continue operating safely and efficiently.
Can you repair existing unvented hot water systems?
Yes. We diagnose and repair many common unvented cylinder faults, including pressure problems, leaking valves, faulty thermostats, immersion heater issues and expansion vessel faults. We will inspect the system before recommending the appropriate repair.
Are unvented hot water systems safe?
Yes, when they are correctly installed and maintained. Modern unvented systems include several built-in safety devices designed to control pressure and temperature. These components should be checked during routine servicing.
Can an unvented system be installed in an older property?
Often, yes. Suitability depends on factors such as incoming mains water pressure, flow rate, available space and the condition of the existing plumbing. We can assess the property and recommend whether an unvented cylinder is appropriate.
What are the benefits of an unvented hot water cylinder?
An unvented cylinder can provide strong mains-pressure hot water, improved shower performance, more installation flexibility and no requirement for a cold-water storage tank in the loft. It can be particularly suitable for homes with several bathrooms or higher hot water demand.
