One of the smallest plate heat exchangers for heating systems in the Nordic Tec manufacturer's catalog, with 20 plates, with a nominal power of up to 45 kW (calculated for so-called high feed temperatures). A heat exchanger of this size is used for connecting additional circuits to existing heating or cooling installations. Alternatively, it can handle entire central heating systems, but provided they are not too large - typically suitable for apartments rather than entire buildings. Recommended for small heat exchange systems.
The heat exchanger has a heat exchange surface of 0.24m² and 3/4" connections. Optionally, this model can be purchased with insulation and a mounting kit. It remains one of the smallest heat exchangers available on the European market.

Technical details - Plate Heat Exchanger for small systems | Ba-12-20:
The Ba-12-20 heat exchanger, due to its small heating exchange surface area, is rarely suitable for servicing heating devices in their entirety; rather, it's intended for connecting additional circuits. It is not designed to handle the entire central heating system in a single-family house or apartment unless the space is very small.

___________________________________
It is recommended to clean plate heat exchangers at least once a year. During installation, it is best to separate the exchanger from the installation using shut-off valves. This way, we can disconnect it from the installation without draining the water from the heating system, and removing the exchanger for cleaning - or replacing it with a new one sooner or later will be necessary. If we don't think about it during installation, we need to drain the water from the installation and remove the exchanger.
After removing the exchanger from the installation, it should be filled with a descaling agent and left overnight. If this method is used at least once a year - and the exchanger is properly sized - the device should last for at least several years. After this period, it will need to be replaced with a new one.
