What it is
The Ideal Flow Sensor Kit is a replacement sensor assembly for Ideal gas boilers, listed under part number 175979. It sits within the appliance's water circuit and provides the control board with a flow signal, allowing the boiler to regulate heating and hot water demand accurately. The kit is supplied under the Ideal Spares brand and is classed within the thermostats, thermistors and sensors group of spare parts.
Signs this part needs replacing
- The boiler does not fire on a hot water demand while the heating circuit still runs normally
- Hot water temperature is intermittent or fluctuates noticeably at the tap
- The appliance locks out or displays a fault code linked to flow or temperature sensing
- The boiler cycles or shuts down shortly after ignition
- No response from the boiler when a hot water outlet is opened
Before you order
- Check the GC number on the appliance data badge against the compatibility list below before ordering, as several Logic and Logic+ variants use different sensor arrangements.
- Cross-reference the alternative part number 1781648 if you are working from older service documentation or an existing part label.
