What it is
The 0020135133 is a six-coil domestic hot water heat exchanger fitted to Vaillant's ecoTEC Plus 630 combi boiler range. It transfers heat between the primary heating circuit and the domestic hot water passing through it, so the boiler can deliver hot water on demand.
Signs this part needs replacing
- Loss of instant hot water or a delay before hot water arrives
- Reduced or fluctuating hot water temperature at the tap
- Cross-contamination between heating and hot water circuits
- Scale build-up reducing flow through the coils
Before you order

- Match the part number printed on your existing heat exchanger
- Isolate gas, electricity and water before removal
- Have the replacement fitted by a Gas Safe registered engineer
