An unvented cylinder gives you mains-pressure hot water without a loft tank, which means a better shower and hot water on demand to more than one tap at once. They are a superb upgrade for a busy household, but they must be installed and serviced correctly for safety.
Our engineers are qualified to work on unvented systems (G3). We can install a new cylinder as part of a heating upgrade, replace an ageing one, or service and safety-check your existing system so it keeps running reliably.

Common questions
What is the benefit of an unvented cylinder?
You get strong, mains-pressure hot water to every outlet, no cold-water storage tank in the loft, and hot water to several taps at once. It is a noticeable improvement for most homes.
Do unvented cylinders need servicing?
Yes. An annual service keeps the safety components working correctly and protects your warranty. We can service cylinders we did not install too.
Are your engineers qualified for unvented work?
Yes. Unvented hot water work requires a specific qualification (G3), which our engineers hold.
