Plate Heat Exchanger for Hermann Micra Boiler - Ref. 015002479
The plate heat exchanger for the Hermann Micra boiler - Ref. 015002479 is a component that transfers heat from the primary circuit to the domestic hot water instantly. When it fails, the water that comes out may be lukewarm or have fluctuating temperatures, and the flow of hot water is also reduced. This model is compatible with several boilers, such as the Micra 23 E, Micra 24 SE, and Supermicra 30 SE, among others. It is recommended to replace it when these symptoms of poor performance in hot water supply are noticed.

How to check if ref. 015002479 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 015002479. 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 015002479 solves.
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 takes much longer than usual to come out hot from the tap.
Cause: Calcified plates reduce the efficiency of the heat exchanger, and more burner time is needed to notice the temperature change.
Time how long it takes from when you open the tap until really hot water comes out; if it has increased over the months, check the heat exchanger.
- 02
The flow of domestic hot water decreases the longer you keep the tap open.
Cause: The blockage caused by limescale in the heat exchanger channels limits the flow that can pass continuously.
Compare the flow rate when opening the tap with the flow rate after two minutes; a significant drop indicates blocked channels in the heat exchanger.
- 03
There is moisture or dripping under the boiler that does not match any pipe or bleed valve.
Cause: The gaskets of the heat exchanger degrade with use and allow water to escape in their mounting area.
With the boiler cold, dry the area and run it for a while to see if the humidity reappears right around the heat exchanger.
- 04
The heating circuit repeatedly loses pressure without visible leaks in the radiators or valves.
Cause: A PCB with a microcrack allows water to pass between the heating circuit and the mains circuit, and the system depressurizes or overpressurizes depending on the case.
Keep a simple record of the cold pressure over a week; a constant loss without visible leaks is an indication of an internal leak in the heat exchanger.
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.
