Why not use a fully filled system?


The ISL system has a number of advantages:
  • There is no expansion vessel to regularly service. We simply have a small air pocket that absorbs any water expansion as the system becomes hot.
  • Very low maintenance, as the system does not need servicing or re-pressurising if there are any leaks or a release of water from the pressure relief valve.
