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.
- Heat Exchange Surface - 0.240 m²

(D) - 40 mm
How it works? How does a Plate Heat Exchanger or PHE - Ba-12-20 works in heating system?
Plate heat exchangers by Nordic Tec optimise temperature transfer between 2 fluids. The steel plates have only 0.3 mm of thickness to make this process easier. Additionally the plates of exchangers are corrugated. In the serie of PHE Ba-12 by Nordic Tec the heat exchange surface per one single plate is 0.012m². The unit Ba-12-20 consists of 20 plates, which make together the surface 0.24m². The heat transfer surface is the key for the correct sizing of the device and the sizing itself should be done by the professional.
This heat exchanger is in most cases, because of its rather small dimensions, not destinated for heating houses in a whole - but it is a good choice for connecting additional circles to the existing central heating systems.If you got any technical questions about PHE - feel free to contact us

How to clean the heat exchanger in central heating installations and how often?
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.
