Viessmann spare parts
Viessmann spare parts help you find suitable components for Viessmann heating technology, heat generators, heat pumps, storage technology, control technology, and hydraulic system components. It is important to reliably identify them by manufacturer, model, model series, type plate, MPN, OEM number, or spare part type.
Before ordering, always check the product information and compatibility with your system. Original or compatible spare parts must be clearly matched using the respective item data, technical documentation, or exploded view diagrams.

Notes
Use the filters to narrow down the selection by relevant characteristics such as manufacturer, product type, area of application, technical features, or availability. The information is provided for orientation purposes and does not replace a check of the technical suitability, compatibility, or proper use of the product.
Viessmann spare parts for heating technology, heat pumps and system components
Viessmann spare parts are needed when heating appliances, heat generators, heat pumps, storage technology, controls or hydraulic system components need to be serviced, repaired or technically inspected. In this category you will find manufacturer-related spare parts and matching components that can be used for the repair, maintenance or technical preservation of Viessmann systems and system technology.
Especially with modern heating technology, clear identification is particularly important. Many spare parts look similar but differ depending on the model, model series, appliance generation, connection, electrical specification, function or installation position. Therefore, always check the information on the rating plate, the existing article number, MPN, OEM number, technical documentation or exploded view diagram before ordering.
Typical spare parts for Viessmann systems
- Seals, O-rings, connection components and small technical connecting parts
- Sensors, probes, temperature controllers and monitoring components
- Valves, pump components, hydraulic parts and system components
- Controls, circuit boards, ignition components and electrical spare parts
- Components for maintenance, replacement and technical inspection of suitable heating and system technology
What you should consider when selecting
The selection of a spare part should not be based solely on visual similarity. What matters is the manufacturer, model, model series, device version, connection, function, and the exact spare part type. Original or compatible spare parts must be checked against the product specifications. A blanket compatibility guarantee is not possible without comparing with the specific system.
For gas-carrying, electrical, water-carrying, pressurized, or safety-relevant components, proper inspection and installation are especially important. Work on heating appliances, heat pumps, controls, safety components, valves, or hydraulic connections should only be carried out with sufficient technical expertise or by qualified specialist personnel.

Questions and answers about Viessmann spare parts
How do I find the right Viessmann spare part?
First check the information on the nameplate of your system or component. The manufacturer, model, model series, device version, MPN, OEM number or the exact spare part designation are important. If an exploded view diagram, spare parts list or technical documentation is available, the assignment should also be checked against it.
Are all Viessmann spare parts automatically original parts?
No. Depending on the item, a spare parts category may contain original or compatible spare parts. Whether it is an original part or a compatible spare part must be checked based on the respective product information.
Can I use a similar-looking spare part?
Optical similarity is not sufficient for heating technology. Despite similar designs, spare parts can differ in connection, material, electrical values, function, installation position or safety-relevant properties. Compatibility must always be checked based on the technical specifications.
Which Viessmann spare parts are frequently needed?
Frequently requested are seals, sensors, probes, valves, pump components, control boards, ignition components, connection components, control components and other technical parts for heating appliances, heat pumps, storage technology and system technology.
May I install Viessmann spare parts myself?
This depends on the component and the system. For gas-carrying, electrical, water-carrying, pressurized, or safety-relevant components, inspection and installation should be carried out by a qualified professional. Work on heating appliances, heat pumps, controls, and safety devices should only be performed with the appropriate expertise or by qualified specialist personnel.
