Fagor Bithermal Plate Heat Exchanger FEE 20 2 B Ref. FA000070
If you notice that the hot water comes out lukewarm or with fluctuating temperature, you may need the Fagor Bitérmico Plate Heat Exchanger FEE 20 2 B Ref. FA000070. This part is responsible for transferring heat from the primary circuit to the domestic hot water instantly. When it fails, the flow of domestic hot water decreases and can cause discomfort in daily use. This heat exchanger is compatible with several models, including the Ecocompact 20E, FEE-20, and CE-20E, among others. It is recommended to replace it when these symptoms of malfunction occur.

How to check if the reference FA000070 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 FA000070. 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 FA000070 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 does not reach the usual temperature, especially during months of high consumption.
Cause: Limescale builds up on the heat exchanger plates, reducing their capacity to heat the water.
Check if the water in the area is hard and if the boiler has a water softener before deciding to replace the part.
- 02
The flow of hot water is significantly lower than before, with the boiler pressure being normal.
Cause: The internal channels of the heat exchanger narrow due to accumulated scale, limiting the flow of water.
First, check the cold water inlet filter; a dirty filter can cause the same symptom.
- 03
It is necessary to replenish pressure in the heating system more frequently than usual, without visible leaks on the outside.
Cause: An internal crack in the heat exchanger allows water to pass between the primary circuit and the domestic hot water circuit.
Check for several days if the pressure drops with the filling valve closed to confirm the leak before replacing the part.
- 04
A boiling or bubbling noise can be heard inside the boiler when heating.
Cause: The accumulated scale in the heat exchanger creates hot spots that cause the water to boil in those areas.
Check if the noise occurs only when requesting hot water; this helps to differentiate the heat exchanger from other causes.
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.
