Unvented Hot Water Cylinders in Epsom
Repairs, servicing and replacement of unvented hot water cylinders in Epsom and nearby areas. Clear advice, proper checks and professional work from an experienced local plumbing and heating engineer.
Unvented cylinder repairs and replacement
Unvented hot water cylinders are common in modern homes because they provide strong mains-pressure hot water without needing a cold water storage tank in the loft.
When they are working properly, they give excellent hot water performance for showers, baths and busy family homes. When they go wrong, they need to be checked properly because they are pressurised hot water systems with important safety controls.

Why use a G3 qualified engineer?
Unvented cylinders store hot water under pressure, so they are not the same as a basic cold water tank or open vented cylinder. They have specific safety controls that need to be understood and checked correctly.
A G3 qualified installer understands how these systems should be installed, serviced and repaired, including pressure controls, expansion arrangements, temperature controls and discharge pipework.
If something is wrong, I will explain the fault clearly and let you know whether repair or replacement is the better option.

Unvented cylinder FAQs
Do unvented cylinders need servicing?
Yes. Unvented cylinders should be checked regularly because they include safety controls, pressure controls and discharge pipework. A service can help spot faults before they become more serious.
Why is water coming out of the discharge pipe?
Water discharging from an unvented cylinder can be a sign of a fault with the expansion vessel, pressure reducing valve, temperature and pressure relief valve, or another safety component. It should be checked rather than ignored.
Can you replace an immersion heater on an unvented cylinder?
Yes, in many cases an immersion heater can be replaced if it has failed. Access, cylinder condition and the type of immersion fitted all need to be checked first.
Can you replace my old unvented cylinder?
Yes. If the cylinder is old, leaking, badly scaled or not worth repairing, I can quote for a suitable replacement and explain the options clearly.
Do you cover areas outside Epsom?
