What it is

The Ideal 175590 is a flow sensor designed for use in Ideal Heating appliances. It monitors the movement of water through the heating or hot water circuit and provides a signal to the appliance's control system. This signal is used to confirm that water is flowing, allowing the boiler to fire and modulate its output accordingly. The sensor uses Hall effect technology, which detects flow via a magnetic field and generates a pulse output. This type of sensor has no mechanical parts that wear against the water flow, making it reliable over time. The part is supplied in used condition.

Signs this part needs replacing

  • The boiler fails to fire when a hot water tap is opened.
  • Hot water runs intermittently or at inconsistent temperatures.
  • The appliance displays an error code related to water flow or demand.
  • The heating system does not respond to a call for heat.
  • The appliance does not modulate its output in response to flow changes.

  • This part is supplied in used condition.
  • No GC number is recorded for this part.
