How to check if ref. 122030670 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.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference 122030670. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the bivalent heat exchanger 122030670 solves.

The bivalent heat exchanger transfers heat to heating and domestic hot water. These are the typical symptoms and what to do:

Common symptoms and faults

• 01

  The domestic hot water comes out at a low temperature or takes a long time to heat up, even though the boiler works well in heating mode.

  Cause: Limescale deposits in the narrow passage of the domestic hot water system and reduces heat transfer to the water supply.

  Check the water hardness in the area and whether the boiler has a water softener or anti-scaling filter installed.

• 02

  The boiler gradually loses pressure in heating, without any visible external leak.

  Cause: An internal perforation in the plates of the bithermal heat exchanger mixes the heating circuit with the domestic hot water circuit, and the water escapes through the tap.

  Close the cold water inlet valve and observe if the heating pressure gauge continues to rise or fall on its own; if it varies, there is a crossover between circuits.

• 03

  You hear banging or a whistling noise in the boiler when it demands heating or domestic hot water.

  Cause: Limescale deposits narrow the internal pipes, causing the water to flow faster and generate noise.

  Check the water hardness and if it's been a while since a chemical cleaning or descaling of the heat exchanger has been done.

• 04

  When opening a hot water tap, it first comes out cold and then suddenly hot, or it cools down for no reason in the middle of a shower.

  Cause: A bithermal heat exchanger with partially adhered scale does not react quickly enough to changes in flow rate.

  Turn the hot water tap fully on and check the flow; if it comes out with low pressure, you should first rule out a blockage in the pipe or the tap.

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.
