Alpha Cb Filling Loop 3.015849

The filling loop is a part that only occurs on boilers and systems that deal with central heating. The filling loop allows the user to manually alter the amount of water within the central heating system if the pressure has dropped to low. Filling loops can be external or internal, depending on the type of appliance you have. If the loop is external, it will usually be removable as the water regulations state that the loop must be removed after use. However, if the loop is internal, there is usually a key that can be removed to interrupt the filling loop connection after use.

This part is present in 17 different boilers in the Alpha range including the Alpha CD 24 , CD 32 , CB 24 , CB 28 , CB 28X .
