Cooling coil WZS-1 is designed to protect the central heating boiler from overheating (water boiling). Boiling water in the boiler or the central heating installation can lead to boiler or installation damage.
Boiler cooling coil should be used in a closed central heating water system. The central heating working in an open system can also be secured with a safety heat exchanger for the boiler because it does not affect directly the normal boiler operation.
Protection in the form of a WZS-1 cooling coil in enough for boilers from 10 to 35 kW.
To properly connected a cooling coil, remember to mount a pressure reducing valve, because reducing the working pressure to 2 bars gives a better performance.
