What it is

The Ideal 175418 is a plate heat exchanger kit rated at 30kW, produced by Ideal for its domestic gas boiler range. It is listed for the Isar HE, Evo C and Independent appliance families. Inside a combi boiler the plate heat exchanger sits between the primary heating circuit and the domestic hot water circuit, transferring heat from the boiler water into the mains-fed hot water supply without the two ever mixing.

Signs this part needs replacing

  • Domestic hot water temperature fluctuates or alternates between hot and cold
  • Hot water flow rate drops noticeably at the tap
  • Water leaves the boiler below the temperature set on the control
  • Scale or system debris has blocked the plate passages, reducing heat transfer
  • Weeping or dripping from the plate stack or its seals

Before you order

  • Confirm the boiler model and GC number before ordering, as the same part number can appear across several appliance families
  • Check the part number stamped or printed on the existing component against 175418
  • Inspect the seals and gaskets on the existing plate before refitting and replace them if they are compressed or damaged
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
