What it is
The Pipe CH Return H120 is a Worcester Bosch pipe component for the central heating return circuit. It is manufactured by Worcester Bosch for use in Greenstar 4000 System appliances. Its role is to carry returning heating water through the boiler's internal pipework as part of the sealed heating circuit.
