The Worcester Keyless Filling Link has been developed to make system filling quick and easy for both the installer and the end user. Designed for installers to make the maintenance of a home heating system easier for their customers by removing the difficulty they often experience in operating the filling link after the temporary connection has been made. In turn, this reduces the amount of enquiries installers receive from those who have removed a radiator and need to top up the system with water. The product also removes the need for the end-user to temporarily join the water mains and the heating circuit together with a key or the more traditional braided hose pipe arrangement. Additionally:

- The Keyless Filling Link is an easily operated alternative to the filling key or hosepipe which customers often lose or find difficult to use.
- It is an optional extra and is compatible with all wall mounting jigs used across the Worcester Greenstar range of gas-fired combi and system boilers.
