Overview average costs

Factors that influence the costs

The amounts mentioned are indicative prices. In practice, the costs may differ due to, among other things:

• Provider: Each company uses its own rates and methods.
• Region: Labor and call-out charges may vary by region.
• Type and age of the boiler: Older or less common types of boilers often require more maintenance or more expensive parts.
• Contract type: The more extensive the service package, the higher the annual costs.
• Call-out charges: Not every provider charges these separately; sometimes they are included in the contract.
• Parts: Costs for replacement parts are not always included in the contract price.

Why regular maintenance of the boiler is important

Regular maintenance of a boiler is essential for safe and trouble-free operation. It not only ensures more efficient energy use but also contributes to a longer lifespan of the system. The main reasons are:

• Safety
  A well-maintained boiler reduces the risk of dangerous situations, such as carbon monoxide leaks. Technical components are checked and adjusted, ensuring the system continues to operate safely.
• Energy efficiency
  A clean and correctly adjusted boiler works more efficiently and consumes less gas. This results in lower energy costs and a reduction in unnecessary energy loss.
• Extended lifespan
  Regular maintenance helps limit wear and tear and ensures parts are cleaned or replaced in a timely manner. This typically extends the boiler's lifespan.
• Preventing malfunctions
  Timely maintenance allows incipient technical problems to be detected and resolved early. This prevents unexpected malfunctions and high repair costs.
• Maintaining warranty
  Many boiler manufacturers require periodic maintenance to continue to be eligible for the manufacturer's warranty. Without maintenance, the warranty may expire.
