Unvented Cylinder Service in Maidstone

The practical benefits of an unvented cylinder are compelling for Maidstone homeowners:

• No loft tank — Frees up loft space for conversion, which is a popular renovation in the town's terraced housing
• Mains-pressure hot water — Powerful showers without a pump, delivered consistently to every bathroom
• Equal pressure upstairs and downstairs — No loss of performance at upper-floor outlets
• Reduced frost risk — Eliminating the loft tank removes the risk of frozen pipes in the loft during cold Maidstone winters

However, the high-pressure nature of these systems means the safety devices — temperature and pressure relief valves, expansion vessels, and high-limit thermostats — must be tested annually by a qualified engineer to ensure they will activate when needed.

Maidstone has a growing number of these installations, particularly in the ME15 postcode where bathroom renovations and loft conversions are common. Whether your cylinder was fitted last year or ten years ago, annual servicing keeps it safe, compliant, and covered by the manufacturer warranty.

• Temperature and pressure relief valve (T&P valve) test
• Expansion vessel pre-charge pressure check
• Tundish and discharge pipework inspection
• Immersion thermostat and high-limit thermostat test
• Pressure-reducing valve and check valve inspection
• Visual inspection for leaks and corrosion
• Written service report

Annual unvented cylinder servicing in Maidstone starts from around £120. This includes the full inspection of all safety devices and a written service report. Any repairs identified during the service — such as valve replacement or expansion vessel re-pressurisation — are quoted separately and clearly before any additional work begins. You are never committed to repairs without agreeing the price first.
