Cointra Excellent D Micro LN 24 E Plate Heat Exchanger Ref. 39820430
The Cointra Excellent D Micro LN 24 E plate heat exchanger transfers heat from the primary circuit to the domestic hot water instantly. If it malfunctions, the water may come out lukewarm or experience fluctuating temperatures, and the flow of DHW may also be reduced. This part is compatible with boilers from the Cointra Excellent Micro LN, Cointra Superlative ranges, and several Ferroli models such as Divatop and Divatech, among others. It is recommended to replace the heat exchanger when these symptoms of ineffective operation are noticed.

How to check if the ref. 39820430 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 39820430. 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 heat exchanger 39820430 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 hot water comes out with the temperature constantly changing, or the boiler loses pressure for no apparent reason.
Cause: The heat exchanger distributes heat between the two circuits of the boiler, and if the plates are encrusted or damaged, that distribution becomes irregular.
First, measure the pressure of the circuit with the boiler cold and check for scale in the water inlet filter before replacing the part.
- 02
There are water leaks around the area of the heat exchanger.
Cause: Over the years, the gaskets or the control boards themselves deteriorate and allow water to pass through.
Locate the exact point of the leak with the boiler running to rule out that it comes from a neighboring fitting.
- 03
The boiler takes longer to heat the water or does not reach the temperature it should.
Cause: The accumulated scale between the plates reduces the heat exchange surface, and heat transfers less effectively from one circuit to another.
Check the water hardness of the installation and if the circuit has a scale inhibitor filter before declaring the part as exhausted.
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.
