The best place for a SpiroCombi in your system
The position of the SpiroCombi is important for optimal operation:
- In heating systems: Placement in the supply line is preferred, as the water is warmest here, which allows air bubbles to escape more easily.
- Alternative in case of lack of space: If placement in the supply line is not possible, the SpiroCombi also works effectively in the return line.
- In cooling systems: Here, placement in the return line, just before the water enters the cooling unit, is preferred to efficiently capture dirt.
