Can I use artificially softened water in the heating circuit with my boiler?

You can have a water softener in combination with our boiler as it will prevent the hot water circuit from scaling up and losing efficiency.  However, the central heating circuit should be filled with hard water and a chemical inhibitor.  This can be done by using the water softener bypass when filling or topping up.  Alternatively, the filling loop feed can be connected upstream of the water softener.
