24 kW Plate Heat Exchanger Demirdökum/Demrad/Airsol Aden HK B 224 Ref. 3003200026
The 24 kW plate heat exchanger from Demirdökum, reference 3003200026, is a key component that transfers heat from the primary circuit to the domestic hot water instantly. When it fails, such as due to limescale blockage or internal leakage, the user will notice that the tap water comes out lukewarm or with fluctuating temperatures, in addition to experiencing a reduction in the flow of domestic hot water. This heat exchanger is compatible with several models, including those from the Aden range such as the BK B 224 and HK B 224, as well as other models from the Atron, Kalisto, Neva, Nitron, and Solaris ranges. It is recommended to replace it when these symptoms are detected to ensure a proper supply of hot water.

How to check if ref. 3003200026 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 3003200026. 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 heat exchanger 3003200026 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
Each time, less hot water comes out, or it is necessary to raise the thermostat more to notice the same as before.
Cause: Limescale accumulates on the plates and reduces the heat exchange surface, so less heat is transferred with the same gas consumption.
Check the water hardness in the area and whether the boiler has undergone descaling maintenance; in hard water without a filter, this is the most common cause.
- 02
There is moisture or dripping at the bottom of the boiler body.
Cause: The joints between the plates of the heat exchanger lose tightness with prolonged use.
Dry the area and turn on the boiler for domestic hot water and heating separately, to see with which function the dripping appears before assuming it is the heat exchanger.
- 03
The boiler takes longer to heat the water or it arrives late at the tap.
Cause: With partially obstructed plates, the heat exchanger needs more time to transfer heat to the flow passing through.
Time the duration until hot water comes out and compare it with another faucet in the house; if the delay is only in hot water, point to the heat exchanger.
- 04
There is a buzzing or forced water noise when hot water is requested.
Cause: The flow is forced to pass through a narrower passage within plates with accumulated scale.
Check if the noise occurs only when opening hot water and not during heating; this way you can distinguish it from a pump issue.
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.
