De Dietrich Chappée: Original Spare Parts and Accessories

To ensure the longevity of your heating system, there’s no secret: you need the right part at the right time.

On this page, ExpertByNet brings together the essential ranges of De Dietrich and Chappée. These two pillars of thermal comfort, united within the BDR Thermea group, today share many common technologies. Whether you need to service a wall-mounted gas condensing boiler, a floor-standing oil boiler, or a heat pump, you’re in the right place.

Why choose our certified parts?

Repairing a Naneo, Vivadens, or Initia boiler is not something to take lightly. Using manufacturer original parts is the only guarantee of restoring your device’s original energy performance.

Our catalog covers all maintenance needs:

• Safety and Hydraulics: Expansion vessels, safety valves, disconnectors, and circulators.

• Combustion: Ignition electrodes, gas blocks, and fans.

• Regulation: External sensors, thermostats, and electronic boards compatible with De Dietrich Chappée.

Expert advice to avoid mistakes

References may look similar, but each part is unique. To avoid any ordering errors, always refer to the nameplate of your device. It’s the identity card of your machine (often located under the cover or on the side of the casing).

Tip: Note the serial number and exact model before browsing our stock. If in doubt, our technical team can help you identify the exact match between the De Dietrich part and your Chappée model (or vice versa).

With stock available immediately and fast delivery, we help you get your heating system up and running without delay.
