The smooth operation of a Viessmann heating system is essential. This ensures optimal interaction between its components, which increases system efficiency. Depending on the type of heating system, this also means fewer resources are used. Furthermore, this can save on heating costs. However, heating system maintenance is often neglected. We’ll explain the heating system maintenance process, provide cost information, and highlight what to consider if you’re considering servicing your Viessmann heating system.
Why is it necessary to service your Viessmann heating system?
Maintaining your heating system generally consists of two components: inspection and maintenance. Both stages are performed by a qualified technician. First, they determine the current condition of the heating system. Based on these findings, the technician determines the appropriate course of action. Maintenance ensures your Viessmann heating system remains in good working order.
Replacement of individual serviced and wearable parts may be necessary. This is called corrective maintenance, which restores the system to its intended condition. After the inspection and corrective maintenance, you will also receive a maintenance report for your Viessmann heating system. It will list the work performed.

What is checked during heating system maintenance?
When servicing your heating system, other checks are performed in addition to the boiler itself. Below are the maintenance steps, using a wall-mounted gas condensing boiler as an example:
- Check all connections on the heating water and domestic hot water side for leaks.
- Measuring static pressure and supply pressure
- Checking the burner seal and burner gauze assembly
- Checking and adjusting the ignition and ionization electrode
- Cleaning the heat exchanger
- Checking the steam trap and cleaning the siphon
- Checking the neutralization system (if present)
- Checking the expansion tank and system pressure
- Checking the safety valve
- Checking the strength of electrical connections
- Combustion quality testing
- Checking the flue system for unobstructed flow and tightness.
- Domestic hot water supply, including temperature setting, tightness and general proper functioning
- The operation and proper settings of heating system pumps, such as heating circuit pumps, cylinder charging pumps and domestic hot water circulation pumps.
Individual factors may vary depending on the type and model of the heating system. For example, a heat pump or fuel cell requires completely different factors than a gas condensing boiler or a traditional oil boiler.
Reasons for Heating System Maintenance
- Avoid high heating costs due to pollution
- Ensure the safety of residents
- Extend the life of the system
- Maintain energy quality
- Maintain warranty (for new systems)
- Prevent environmentally harmful exhaust gases from untreated systems
- Prevent sudden heating outages
- Ensure that insurance covers the costs of consequential damage
It is necessary to carry out regular maintenance of the heating system.
Heating systems operate at full capacity for three to five months a year. Therefore, regular maintenance is essential. However, there are no legally required timeframes. In any case, summer is a good time to service a Viessmann heating system. If consistent warmth has already set in very early, late spring is also a good time. In any case, heating system maintenance should be performed before the start of the next heating season.
What costs can you expect when servicing your heating system?
Maintaining a heating system is costly. However, there are no set prices or fixed rates. This is because the cost depends on a number of factors, such as
- heating type
- volume of work
- local conditions
- adequate settings
- spare parts or replacement of wearing parts, if necessary
In particular, subsequent heating system maintenance services cannot be covered by a fixed fee. In some cases, the contractor may also need to replace wear parts during maintenance. All these additional services are included in the heating system maintenance cost and, accordingly, determine its price. Due to this complexity, it is impossible to specify a fixed fee for heating system maintenance; the cost can only be determined on a case-by-case basis.
Maintenance Contract: The Benefits Speak for Themselves
A heating system maintenance contract ensures regular system maintenance and typically offers more attractive terms. A long-term contract provides greater cost-effectiveness for both you and your service provider.
You won’t have to compare quotes or renew your maintenance contract every year. Another benefit of signing a maintenance contract is that you’ll never forget your maintenance due date again.
Finally, you can specify customized services in such a contract. This way, you’ll receive a service package tailored to your needs. If you’re looking for a suitable service partner, we’re happy to help. Simply use our form to request a heating system service quote .
Maintenance Contract Contents: What to Look Out For
When entering into a contract for regular maintenance of your Viessmann heating system, you should pay attention to the following points:
- services provided, including description
- terms and intervals of maintenance
- term of the contract and notice period
- a clearly articulated acceptance of responsibility
- on-call service in case of malfunction
- If desired, a response time in the event of a malfunction can also be agreed upon.
