What it is
The Glow-worm 0020070706 is a flow limiter rated at 16 litres per minute, fitted within the domestic hot water circuit of the appliance. It restricts the volume of water passing through the DHW side of the boiler so the draw-off rate stays within the design figure for the unit. It is used on the Glow-worm Ultracom CXi range of gas boilers.
Signs this part needs replacing
- Domestic hot water draw-off rate has risen noticeably above the appliance's rated figure.
- Hot water flow is erratic or surges at the tap despite stable mains pressure.
- The limiter is blocked or scaled, restricting hot water flow below the expected rate.
- Visible damage, deformation or debris build-up on the limiter body when inspected.
- Hot water temperature control becomes difficult because the flow rate through the boiler is inconsistent.
Before you order
- Confirm the appliance model is an Ultracom 24CXI, 30CXI or 38CXI.
- Check the existing limiter against the part number 0020070706 before ordering.
- Confirm the rated flow figure marked on the existing component matches 16 litres per minute.
- Verify the limiter is accessible and can be isolated before starting work.
