Zilmet Plate Heat Exchanger for Baxi Roca FEB 24 AR and Compatible Models
If you notice that the hot water is lukewarm or has an unstable temperature and the flow of domestic hot water has decreased, you may need a new Zilmet plate heat exchanger for the FEB 24 AR boiler and compatible models. This part is responsible for transferring heat from the primary circuit to the domestic hot water instantly. It is compatible with boilers from the FEB range, as well as with the CE 24 E, CE 30 E, FE 18 E, FE 23, FE 24 E, FE 26 E, FE 27 E, and FE 30 E models, among others. It is recommended to replace the heat exchanger when it shows faults in temperature or water flow.

How to check if the part number MU0886000 is the one 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 MU0886000. 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 MU0886000 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 domestic hot water comes out intermittently, alternating between hot and cold, without you changing the faucet.
Cause: A heat exchanger with irregular heating heats the water inconsistently depending on the flow rate at any given moment.
Try opening the tap with more and less flow; if the temperature varies significantly with the flow, the heat exchanger may be partially blocked.
- 02
It costs more than usual to fill the bathtub or the shower takes time to reach temperature.
Cause: Calcified plates transfer less heat per unit of time, and the water needs more seconds to heat up.
Time how long it takes for stable hot water to come out; if that time has been increasing over the months, check the heat exchanger.
- 03
The heating works without any issues, but the domestic hot water system fails or the boiler locks up when requesting hot water.
Cause: A heavily scaled heat exchanger does not transfer enough heat, and the control unit detects a temperature anomaly in the domestic hot water circuit.
Check if the fault only occurs when opening a hot water tap and not in heating mode; that points to the heat exchanger rather than the PCB.
- 04
There is a visible limescale or sediment stain in the area where the heat exchanger is mounted upon removing the cover.
Cause: Hard water leaves limescale residue on the plates, especially on those closest to the inlet.
If you are going to open the boiler anyway, check the condition of the PCBs before ordering the part; sometimes just descaling is enough.
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.

Data read on the part and in the manufacturer's documentation
What we have not been able to verify does not appear here.
- Actual manufacturer of the component
- Zilmet (Italy)
- The current catalog lists the same reference (MU0886000) for this part and for the data sheet of the FE 24E N heat exchanger, a different boiler model; it is likely a catalog error. Do not use it to confirm compatibility.
