High Zone Heat Pump System
Observed benefits other than energy saving:
- Smoother operation, Central monitoring and operation by master control panel.
- Reduced maintenance cost due to less equipment used.
- No CO2 exhaust to environment on site.
- Stable and continuous hot water output.
- Better water balancing supply.
General observations of the retrofitting project:
