Below are PHE with optimal parameters for connecting gas boilers operating in a closed system with an open system installation.
How to size a plate heat exchanger for connecting a condensing boiler to a central heating system
To properly select - for every 10kW of a gas boiler, there should be at least 0.30m² of exchanger plate surface (heat transfer area). This calculator includes healthy oversizing, i.e. it allows effective heating at low operating temperatures to keep gas consumption low (condensation). With 0.30m²/10kW, the exchanger should work efficiently also after many seasons (taking into account the partial ageing of the device over the years). It should be remembered when selecting that the nominal power of the exchanger does not correspond to the nominal power of the boiler. In the case of relatively new installations - you can safely use a smaller conversion factor, i.e. 0.25m²/10kW of a gas boiler.
Another selection factor is the size of the connections, but the exchanger should be selected based on cross-sections on the installation side, not on the boiler side. It is worth asking the installer about the size of the connections before ordering.
Below is a list of exchangers dedicated to gas furnaces - which you will find in this category:
