Unvented Cylinder Service

Why Does My Cylinder Need A Service?

Manufacturers recommend that you have your hot water cylinder serviced annually to:

• Ensure efficient performance at all times from your cylinder (and a continuous hot water supply!)
• Prevent unexpected bills, with early identification of potential concerns, reducing costly breakdown and emergency call outs
• Minimise the risk of failure  and potential property damage, keeping your home safe

Unvented cylinders have a greater service need due to the water being stored in a sealed, pressurised vessel at high temperatures. Your cylinder should be serviced annually by a qualified engineer and the benchmark log completed to maintain the guarantee on the inner vessel.
