Critical components for troubleshooting your Saunier Duval boiler

A breakdown of a Saunier Duval appliance requires quick intervention and the installation of a quality component to ensure functionality is restored. Our experts have selected the most requested parts for effective repairs.

Essential parts categories:

• Plate heat exchanger: Crucial for the instantaneous production of domestic hot water (DHW) on Thema models. A faulty exchanger (either scaled or leaking) directly affects your comfort.

• Fans and Valves: Fans (flue extractors) and three-way valves (that manage the heating/DHW switch) are common wear parts, vital for condensing boilers.

• Electronic Boards: The brain of the boiler, the board ensures regulation. We provide original electronic boards to maintain the device's communication and safety protocols.

Ensure perfect compatibility: The reference is crucial

Even if your boiler is a "Themaplus" model, Saunier Duval has produced numerous variants. A visually similar part may not be compatible, especially for electronics and hydraulic valves.

• Before ordering one of our Saunier Duval spare parts, always find the serial number and complete manufacturing reference of your device (often on the nameplate sticker inside the cover or under the unit).

• The error code displayed by the boiler (e.g., F28) is also a valuable indication for determining the cause of the breakdown and the part to be replaced.

ExpertByNet's advice: Installing original parts on a Saunier Duval appliance helps maintain the energy efficiency for which it was certified, thus ensuring optimal gas consumption.
