Hot water cylinder repairs and replacement

Help with hot water cylinder faults, leaks, valves, controls and replacement planning across Surrey, Hampshire and Berkshire. We can assess the cylinder and surrounding plumbing, explain the likely cause and discuss repair or replacement options.

Common cylinder issues

Hot water problems we can investigate

A lack of hot water is not always a failed cylinder. Valves, thermostats, immersion heaters, controls, circulation and the heat source can all affect the system, so diagnosis should come first.

Cylinder leaks

Leaks from the cylinder body, fittings, valves or accessible pipe connections.

No hot water

Fault finding where the cylinder is not heating or hot water is unavailable.

Poor hot-water recovery

Hot water taking too long to recover or running out sooner than expected.

Immersion heater issues

Assessment of accessible immersion-heater related faults and the surrounding cylinder arrangement.

Valve and control faults

Problems involving accessible motorised valves, thermostats or cylinder controls.

Cylinder replacement

Planning replacement where the existing cylinder is leaking, unsuitable, obsolete or no longer economical to repair.

How we approach it

Check the whole hot-water arrangement, not just the cylinder

The cylinder stores the hot water, but the fault may sit elsewhere in the system. We look at the symptoms, heat source, controls, valves and accessible cylinder components before deciding what needs attention.

Where an unvented cylinder is involved, work is limited to the scope that can legally and safely be carried out by appropriately qualified personnel.

Useful to know

When cylinder replacement needs more planning

Replacing a hot water cylinder can involve more than swapping one vessel for another. Size, controls, discharge arrangements, access and the property’s hot-water demand all matter.

Cylinder size

The replacement should suit the property’s normal hot-water demand and available space.

Access

Cupboards, lofts and tight plant areas can affect removal and installation.

Controls and valves

Existing controls may need to be retained, altered or replaced depending on the system.

Unvented requirements

Unvented systems have specific safety and discharge requirements and should only be worked on within verified competent scope.

Questions

Hot water cylinder FAQs

Does no hot water mean the cylinder needs replacing?

No. Controls, valves, the boiler or immersion heater can all cause similar symptoms. The fault should be diagnosed before replacing the cylinder.

Can a leaking cylinder be repaired?

A leaking fitting or valve may be repairable. If the cylinder vessel itself has failed, replacement is normally required.

Do you work on unvented cylinders?

Work is only carried out where it falls within the verified competent scope required for the specific unvented system and task.

Can you help choose the right replacement cylinder size?

Yes. The property’s hot-water demand, available space, heat source and existing system all need to be considered.
