Unvented cylinders are safety-critical installations. Here's why Manchester homeowners trust us with their hot water systems.

Not sure which system is right for your home, or have a question about your existing cylinder? We've answered the most common questions below.
A vented cylinder relies on a cold water storage tank (usually in the loft) to supply it with water, whilst an unvented cylinder is fed directly from the mains. Unvented systems deliver mains-pressure hot water to every outlet and don't require a loft tank, making them ideal for modern homes and loft conversions.
Yes. Under Building Regulations Part G, unvented hot water cylinders of over 15 litres must be installed and commissioned by a G3 qualified engineer. Failure to use a qualified installer can invalidate your home insurance and create serious safety risks.
A well-maintained unvented cylinder typically lasts 15–25 years. Annual servicing — particularly of the pressure relief valve and expansion vessel — is essential to achieve maximum lifespan and ensure safety.
Common causes include a faulty thermostat, a failing immersion heater, a heat exchanger issue (on indirect cylinders), or an undersized cylinder for your property's demand. We'll diagnose the exact fault and provide a fixed-price repair quote.
In most cases, yes. Switching to an unvented system improves your hot water pressure significantly. We'll assess your mains water pressure and flow rate to confirm suitability and provide a full installation quotation.
