De Dietrich Chappée: Original Spare Parts and Accessories

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.

Expert advice to avoid mistakes
