What must I do when the water pressure of central heating system drops?

It is recommended to maintain the water pressure of central heating system between 1.5-2 bars. Central heating boilers do not activate in order to prevent damage to your device when there is insufficient water in central heating system. In such cases, you can fill water in your central heating system by using the filling cock located at the bottom part of your device. You must have your system examined if your system pressure is constantly dropping.
