Micra Condensing 26 Boiler Plate Heat Exchanger Ref. 020004861
If you notice that the hot water comes out lukewarm or with fluctuating temperature, you may need the heat exchanger for the Micra Condensing 26 boiler, Ref. 020004861. This part, manufactured by Hermann, is responsible for transferring heat from the primary circuit to the domestic hot water instantly. It is installed in boilers such as the Micra Condensing 26, among others like the TOP 26 CONDENSING, COND 26, and CONDENS 26. It is recommended to replace it when there are issues with temperature or flow in the hot water.

How to check if the reference 020004861 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 020004861. 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 020004861 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 lukewarm or the temperature fluctuates on its own while you shower.
Cause: The heat exchanger plates are clogged with scale, and the flow does not always receive the same heat.
Open the tap to a lower flow; if the temperature stabilizes with less water, the problem is in the heat exchanger.
- 02
The boiler suddenly loses temperature as soon as another tap is opened at the same time.
Cause: A heat exchanger that performs less due to scale does not have enough power when the flow is distributed between two points.
Check if the problem occurs only with two simultaneous demands or also with just one; if it only happens with multiple at the same time, it does not point solely to the heat exchanger.
- 03
Water is leaking from the bottom of the boiler, near the body of the heat exchanger.
Cause: The joints or the welding between plates give way with the cycles of pressure and temperature.
Dry the area, turn on the boiler, and check if the dripping occurs when requesting domestic hot water; this way you can differentiate it from a nearby fitting.
- 04
The pressure in the circuit drops without any visible leaks outside.
Cause: An internal micro-leak in the heat exchanger can allow water to filter from one circuit to another without leaking to the outside.
Fill up to the correct pressure, close the drain valves, and monitor the manometer for a couple of days without using the boiler.
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.
