Secondary Plate Heat Exchanger Hermann Renova Micra 2 24E Ref. 015002479
If you notice that the hot water comes out lukewarm or with unstable temperature, you may need the secondary plate heat exchanger Hermann Renova Micra 2 24E. This part is responsible for transferring heat from the primary circuit to the domestic hot water instantly. When it fails, the flow of DHW decreases and the temperature becomes erratic. It is compatible with several models, such as the Micra 2 24 E, Micra 2 24-30 SE, and Micra 2 30 SE, among other boilers in the Micra and Renova range. It is recommended to replace it when you experience these symptoms to restore the proper temperature of the hot water.

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
There is no hot water or the temperature varies for no apparent reason.
Cause: The heat exchanger of the secondary circuit heats the domestic hot water using heat from the primary circuit through the coil.
Check that the cold water inlet flow is normal and that there is no air in the circuit before replacing the part.
- 02
There is moisture or dripping at the bottom of the boiler, near the secondary heat exchanger.
Cause: The finned tube of the coil deteriorates over time and due to limescale, which causes water leaks.
Dry the area and check if the dripping only occurs when requesting domestic hot water, not when using the heating.
- 03
The hot water takes longer than usual to come out or loses pressure during the shower.
Cause: The accumulation of scale in the secondary coil obstructs the flow of water and reduces the heat exchange with the primary circuit.
Check if you have a water softener installed and when the circuit was last cleaned; if there is no maintenance, limescale is the first thing you should check.
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.
