Technical spare parts for service and replacement

Spare parts for heating systems are used for maintenance, repair, fault diagnosis and replacement of technical components. In this category you will find parts for heat pumps, pellet boilers, electric boilers and related heating installations.

For installers and service companies, it is important that a component is not only physically compatible, but also technically correct for the system. Key factors include voltage, output, control logic, connections, sensor signals, pressure range and software compatibility.

Spare parts for heat pumps

For heat pumps, components such as PCBs, sensors, compressors, fan motors, expansion valves, pressure switches and control panels are essential for reliable operation. These parts are commonly used during diagnostics, repair or preventive maintenance.

For brand-specific selection, view the ALPS EXCLUSIVE spare parts and SPRSUN spare parts.

Spare parts for pellet boilers

Pellet boilers contain several service and wear components, including igniters, burner trays, auger motors, flue gas fans, sensors, springs, turbulators and control components. The correct version is important for combustion, pellet feed and system safety.

For brand-based selection, you can also view Kepo spare parts and ABC spare parts.

Electric boiler parts and control components

In electric heating boilers, PCBs, relays, transformers, sensors, circulation pumps and control panels play an important role in system control and safety. Always check the appliance type, series and technical specifications before replacement.

For electric boilers and project-based applications, relevant components can be found under Mikoterm spare parts.

Compatibility prevents incorrect installation

A spare part may look very similar to the original component, but differ technically in voltage, rotation direction, resistance, connection type, pressure range or communication protocol. Always compare the article number and type designation.

When in doubt, note the brand, model, serial number and part number of the appliance, so compatibility can be checked more accurately.

Important when ordering spare parts

  • Always check the brand, model, series and year of manufacture of the appliance.
  • Compare the article number, rating plate and technical version of the original component.
  • For electrical components, check voltage, output, connection type and control technology.
  • For sensors and pressure switches, verify measuring range, signal type and connection format.
  • Only use spare parts for appliances for which they are technically suitable.
  • When in doubt, have installation checked or carried out by an installer or service technician.

Frequently asked questions about spare parts

How do I know which spare part is suitable for my appliance?

Check the brand, model, serial number, article number and version of the original component. For technical parts such as PCBs, sensors, fans and pressure switches, the product name alone is often not enough.

Can I replace spare parts myself?

Some components are easy to replace, but electrical, refrigeration-related, flue gas-related and safety-critical parts require technical knowledge. When in doubt, have the work carried out by an installer or service technician.

Why are some spare parts only available on request?

Many technical spare parts are brand-, series- or appliance-specific. To prevent incorrect delivery, access, price or availability may depend on a compatibility and application check.

Which details are needed for spare part advice?

Preferably provide the brand, appliance type, serial number, year of manufacture, part article number and clear photos of the original component. This reduces the risk of ordering the wrong spare part.
