Why Servicing Matters

Why cylinder and thermal store servicing is important

A well-maintained cylinder or thermal store is safer, more efficient and less likely to fail unexpectedly. Regular servicing helps protect the system and the property around it.

Safety

Unvented cylinders are pressurised systems, so routine servicing is essential to help identify pressure-related or component-related risks before they become serious.

  • Pressure-related safety checks
  • Inspection of key safety components
  • Early identification of potential issues
  • Reduced risk of leaks or failures

Longevity

Servicing helps catch smaller issues early, which can reduce wear on the system and help avoid premature cylinder or thermal store replacement.

  • Early fault detection
  • Reduced breakdown risk
  • Helps extend system life
  • Supports planned maintenance
