- Ensure proper grounding and use appropriate wire gauge to handle the current load safely.
7. Water Quality Considerations
Water Hardness
- Hard water can lead to scale buildup inside the heat exchanger, reducing efficiency and lifespan. Consider installing a water softener or a descaling system if your water is hard.
- Regular maintenance, such as flushing the unit to remove mineral deposits, is essential for optimal performance.
Filtration
- Install a pre-filter if your water supply has high sediment levels to prevent clogging and damage to the unit.
8. Regular Maintenance
Scheduled Maintenance
