Zilmet Plate Heat Exchanger Code 17B1901200 For Cointra Excellent Micro Low NOx 24E And Other Models

Stock · 1 unit

If you notice that the hot water comes out lukewarm or with fluctuating temperature, you may need a new Zilmet plate heat exchanger Cod. 17B1901200. This part is responsible for transferring heat from the primary circuit to the domestic hot water instantly. It is installed in Cointra boilers, such as the Excellent Micro Low NOx 24E model, among others. Replacement is necessary when the heat exchanger has blockages or heat issues, which affects the flow of DHW.

Guide

How to check if ref. I39820430 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.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference I39820430. If it is not visible, do not identify the part from its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms and faults that the plate heat exchanger I39820430 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 fine at first and then loses pressure or cools down.

    Cause: The heat exchange surface gets clogged with limescale and transmits less heat over time.

    Check if the domestic hot water flow rate also decreases at other points in the system before replacing the part.

  • 02

    There is a visible water leak in the area where the heat exchanger is mounted.

    Cause: A gasket or the welded body of the heat exchanger has lost its seal.

    Tighten and check the inlet and outlet fittings before assuming the leak is coming from inside the part.

  • 03

    The heating circuit needs to be refilled frequently even though no external leaks are visible.

    Cause: A heat exchanger with an internal leak allows water to pass from one circuit to the other without being noticeable from the outside.

    Check if the pressure in the circuit rises when requesting domestic hot water; this is the typical sign of mixing between circuits.

  • 04

    A strange noise, like boiling, is noticeable when the boiler is heating water.

    Cause: The accumulated limescale on the plates causes hot spots that make the water boil locally.

    Check the water hardness and the overall lime scale condition in the boiler before replacing the part.

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.
