What it is

The heat exchanger front plate is the plate section that closes the primary heat exchanger on Baxi and Remeha Avanta 39C combination boilers. It forms part of the combustion-side assembly, where heat from the burner is transferred into the domestic heating water circuit. This is a 39kW rated component manufactured by Baxi under part number 720544901.

Signs this part needs replacing

  • Water weeping or staining around the heat exchanger body or plate joint
  • Repeated pressure loss on the boiler gauge with no visible external leak
  • Overheating, kettling or noisy boiling from the heat exchanger
  • Localised corrosion, pitting or scale build-up on the plate face
  • Boiler locking out or cutting out on the overheat thermostat during demand

Before you order

  • Confirm the appliance GC number and model against the compatibility list, as the 39C variants share this assembly.
  • Check the existing part number on the boiler against 720544901 and the previous number S62780 before ordering.
  • Inspect the plate joint and any sealing components during strip-down, as these are disturbed when the front plate is removed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
