The Challenge: Severe Scaling from Well Water
The nursing home's water source is underground well water, which created a cascade of operational problems:
- Heat Pump Scaling: The heat pump heat exchanger required frequent acid cleaning due to serious scale buildup.
- Hot Water System: The entire hot water system, including the circulating pump and water tank, was seriously scaled.
- Pump Failures: The water pump was clogged and burned due to scaling, affecting normal operation.
- Rising Costs: Frequent maintenance, acid cleaning, and pump replacements were driving up operational expenses.
