Unvented hot water cylinders

Unvented cylinders give mains-pressure hot water, but they must be fitted and maintained by a qualified engineer.

G3 qualified

Unvented hot water systems store water at mains pressure and need the G3 qualification to install and service safely. Omar Heating Group holds it.

What we do

Install and replace unvented cylinders, service them, test the safety valves and expansion vessel, and repair faults such as loss of pressure, discharge from the tundish and no hot water.

Why servicing matters

The safety devices on an unvented cylinder need checking every year. It's also usually a condition of the manufacturer's warranty.

Common questions

Is my cylinder unvented?

If you have no cold water tank in the loft and strong hot water pressure, it may be. Send us a photo of the cylinder and we'll confirm.

Water keeps dripping from a pipe outside.

That can be the safety discharge working. Don't block it. Contact us and we'll look at it.

Do you service all makes?

We service most common makes. Send the make and model when you get in touch.
