Saunier Duval Isofast Condens F 35 E Plate Heat Exchanger - Ref. S1024800
The plate heat exchangers from Saunier Duval's Isofast range, such as the Isofast Condens F 35 E, are essential for transferring heat from the primary circuit to the domestic hot water instantly. When this part fails, the user will notice that the water comes out lukewarm or with fluctuating temperatures, as well as experiencing a decrease in the flow of hot water. This heat exchanger is compatible with several models from the Isofast range, as well as some from the Isomax and Isotwin ranges. A technician must confirm through diagnosis whether it needs to be replaced when these symptoms of malfunction occur.

How to check if ref. S1024800 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference S1024800. 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 that require diagnosis in the plate heat exchanger S1024800
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 heating works well, but the tap water comes out cold or lukewarm.
Cause: The plates are clogged with limescale and do not transfer enough heat to the domestic hot water.
Bleed the air from the boiler and check the cold water inlet filter before replacing the part.
- 02
The hot water comes out in bursts of temperature, without being constant.
Cause: The plates are partially obstructed, causing irregular water flow and temperature variations.
Reduce the flow at the tap and check if the fluctuation improves, which would indicate a partial blockage in the plates.
- 03
The pressure in the circuit rises on its own without having refilled the system.
Cause: An internal micro-leak in the heat exchanger can allow water from one circuit to pass to another and increase the pressure.
Monitor the manometer for a couple of days without touching the filling, observing if the pressure rises just when using the domestic hot water.
- 04
The boiler activates to heat the water, but it does not heat.
Cause: A heat exchanger almost completely blocked by scale does not allow water to flow between the two circuits.
Before changing it, make sure there is no filter or aerator blocked just before 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.
