What it is

The Baxi 720126401 is an overheat thermostat kit for the Baxi Bermuda BBU 15 HE. It monitors appliance temperature and interrupts the burner sequence when an overheat condition is detected, protecting the heat exchanger and surrounding components from damage. The thermostat is supplied as a kit.

Signs this part needs replacing

  • The appliance repeatedly locks out on overheat and requires resetting
  • The boiler shuts down before reaching normal operating temperature
  • No heating or hot water because the overheat thermostat has tripped and will not reset
  • A lockout or fault indication consistent with an overheat condition
  • The thermostat fails continuity or resistance checks when tested

Before you order

  • Confirm the appliance model is the Baxi Bermuda BBU 15 HE
  • Check the part number on the existing thermostat against 720126401
  • Confirm the fault lies with the overheat thermostat rather than the control board or temperature sensor circuit
  • Check the manufacturer's parts list for your appliance variant before ordering
