Saunier Duval Renova Micra 23 SE Plate Heat Exchanger Ref. S015002463
When you open the hot water tap in your home, the Saunier Duval Renova Micra 23 SE plate heat exchanger is responsible for transferring heat from the primary circuit to the domestic hot water instantly. If this component fails, you will notice that the water comes out lukewarm or has fluctuating temperatures, in addition to experiencing a decrease in the flow of hot water. It is installed in boilers from the Hermann Micra and Renova Micra ranges, such as the Micra 23 E, Micra 28 SE, and Supermicra 24 SE, among others. It is advisable to replace it when it shows blockages or heating issues.

How to check if the reference S015002463 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 S015002463. 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 S015002463 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 a temperature that fluctuates for no reason, and sometimes it cuts off.
Cause: The plates of the heat exchanger accumulate scale on the inside, and the water flow becomes irregular as it passes through them.
Check the domestic hot water flow with the tap fully open; if it has decreased compared to before, an internal blockage is more likely than an electronic fault.
- 02
Water is leaking from the quick coupling fitting that connects the heat exchanger, although the rest of the boiler is dry.
Cause: The gasket of that quick coupling connector is a wear part independent of the PCBs and may fail before them.
Before replacing the entire heat exchanger, check if you only need to replace the gasket of the fitting: tighten carefully and see if the leak stops.
- 03
There are visible leaks right in the area where the heat exchanger is mounted, with drops appearing shortly after the boiler is turned on.
Cause: The body of plates or their joints give way with the cycles of heat and cold and begin to lose tightness.
Mark the area with absorbent paper around the part and start a domestic hot water cycle to locate the exact point of the leak before disassembling anything.
- 04
There is no domestic hot water even though the boiler ignites and heats the heating system properly.
Cause: If the heat exchanger is heavily clogged with scale, it can nearly block the entire water flow of the secondary circuit.
Check if the problem occurs only in domestic hot water and not in heating; if so, the PCB can be ruled out and it points directly to the heat exchanger or the flow sensor.
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.
