What it is
The heat exchanger support is a Vaillant mounting component, part number 0020142174, used on ecoTEC PLUS condensing boilers. It holds and locates the heat exchanger assembly within the appliance, keeping the unit seated correctly against the casing and pipework connections. It is a serviceable part that may need renewing if the original support becomes damaged, distorted or corroded.
Signs this part needs replacing
- The heat exchanger sits loose or moves when the appliance is handled during service
- Visible cracking, distortion or corrosion on the support
- Vibration or rattling from the heat exchanger area in operation
- Difficulty refitting the heat exchanger squarely after removal
- Weeping or staining around the heat exchanger mounting points
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the part number on the existing support or the manufacturer's parts list
- Inspect the heat exchanger mounting points for damage before refitting
- Confirm whether any seals or fixings disturbed during the job also need replacing
