Chaffoteaux Pigma Green 25 Domestic Plate Heat Exchanger Ref. 65104333
When you open the hot water tap, the Chaffoteaux Pigma Green 25 Plate Heat Exchanger is responsible for transferring heat from the primary circuit to the water, providing instant heat. If this part fails, you will notice that the water comes out lukewarm or has fluctuating temperatures, and the flow of domestic hot water may decrease. This heat exchanger is compatible with several boilers in the Pigma range, such as the Pigma 25 FF and the Pigma Green 25, among others. It is advisable to replace it if you experience these symptoms to restore the proper supply of hot water.

How to check if ref. 65104333 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 65104333. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the plate heat exchanger 65104333 resolves.
The plate heat exchanger transfers heat to the domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The water comes out hot at first and then suddenly cools down for no apparent reason.
Cause: A partially obstructed PCB distributes the flow poorly, and the heat exchange becomes unstable.
Open and close the tap a couple of times: if the fault is intermittent and not constant, it points more towards obstruction than breakage.
- 02
The hot water tap has very low pressure compared to the cold water tap.
Cause: The narrow channels of the heat exchanger are the first to become clogged with scale and limit the flow that can pass through it.
First, rule out the faucet aerator and the boiler inlet filter, which are much quicker and cheaper to check.
- 03
There is a water leak that only appears when the boiler is providing domestic hot water, not during heating.
Cause: If the leak occurs only when the heat exchanger is under load, it indicates a crack in its plates or joints.
Note if the dripping always coincides with the use of domestic hot water before replacing the part.
- 04
The performance of the domestic hot water has been gradually worsening over the months.
Cause: Limescale accumulates progressively, so the symptom does not appear suddenly but worsens over time.
Has maintenance or descaling been performed in the last few years? It significantly changes the initial diagnosis.
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
