What it is

The Viessmann 7837230 heating return pipe is an EPDM hose used on the heating return circuit of Vitodens 100-W appliances. It carries returning heating water back through the boiler's hydraulic assembly on both combi and system variants. The part sits within the pipe assembly group of Viessmann gas boiler spares.

Signs this part needs replacing

  • Weeping or dripping at the hose ends or crimped connections
  • Visible perishing, cracking or hardening of the EPDM material
  • Falling boiler pressure that needs regular topping up
  • Staining, scale or corrosion deposits around the hose and its connections
  • Water tracking from the hose onto adjacent boiler components

Before you order

  • Confirm the boiler model and serial number against the fit list above
  • Check the existing hose is marked with part number 7837230
  • Establish whether the appliance is the combi or system variant of the Vitodens 100-W
  • Inspect the hose routing and connection points before removal
