What it is
The Heatline By-Pass Spring is a small internal component used in the by-pass assembly of Heatline gas boilers. It fits models in the Capriz PLUS and Monza families, where it provides the spring tension that governs by-pass operation. This listing is for a pack of five springs.
Signs this part needs replacing
- Boiler fails to hold steady system differential pressure, with by-pass operation inconsistent
- Noise or vibration from the by-pass area during heating operation
- Visible deformation, corrosion or breakage of the existing spring on inspection
- By-pass valve sticking or not returning correctly under changing flow conditions
Before you order
- Confirm the boiler model matches one of the fit lines above
- Check the existing by-pass assembly to confirm the spring is the part required
- Note that this item is supplied as a pack of five, so one pack covers multiple replacements
- Have the appliance GC number to hand when verifying compatibility
