What it is

The Ideal 100270 is a water header supplied for the 150VA-400V Series 4 commercial boiler range. It forms part of the hydraulic circuit, collecting and distributing water through the appliance's pipework. The part is listed by Ideal under part type HEADERS and is used across the Concord Super Series 4 commercial models.

Signs this part needs replacing

  • Water weeping or staining around the header body or its connections
  • Corrosion or pitting on the header surface, often with a crust of scale or oxide
  • Sludge or debris collecting in the header, restricting flow through the circuit
  • Uneven heating or poor circulation across the appliance's water side
  • Repeated pressure loss that traces back to the header assembly rather than the system

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering
  • Check the existing part number on the component and cross-reference it with 100270 and 1175273
  • Inspect the seals and gaskets at the header connections and order replacements if they are disturbed during the repair
