Product Overview
The 1000L Centralized Split Pressurized Solar Water Heating System is designed for continuous commercial hot water applications such as hotels, hospitals, dormitories, and industrial buildings.
It is a centralized solar thermal solution that reduces reliance on conventional energy while ensuring stable multi-point hot water supply.
The system is engineered based on project-specific thermal load calculation, rather than a fixed product configuration.
Typical system includes:
- Solar collector array (flat plate / evacuated tube)
- 1000L pressurized insulated storage tank
- Closed-loop circulation system
- Differential temperature controller
- Optional auxiliary heating system (electric / gas / heat pump)
Final system design depends on:
- Daily hot water consumption (L/day)
- Local solar radiation (kWh/m²/day)
- Building usage pattern (peak demand profile)
Engineering Design Basis
Collector Sizing Reference
- 1.5–2.5 m² collector area per 100L storage capacity
- Adjusted according to:
- Climate zone
- Solar irradiation level
- Required hot water temperature (45–60°C)
Control Logic
- Pump ON when ΔT ≥ 8–15°C
- Pump OFF when ΔT ≤ 3–5°C
System Function
The 1000L tank provides:
- Thermal energy buffering
- Peak load stabilization
- Backup heat storage during low solar periods
