What it is

The Ideal 176135 is a flow regulator manufactured for Ideal domestic and commercial boiler spares. It sits in the water circuit of the appliance and controls the rate at which water passes through, helping the boiler hold a steady flow and a consistent delivered temperature. It is listed against the Logic Code Combi family and carries the manufacturer reference D0415-5.

  • Delivered hot water temperature swings between hot and lukewarm during a draw-off
  • The boiler cycles or cuts out while a hot water tap is running
  • The regulator body is found to be restricted by scale or system debris on inspection
  • Flow rate readings taken at the appliance fall outside the expected figure for the model
