Flat Plate Split Solar Water Heater
Product Advantages:
1. Higher Efficiency: Collectors work well in diffuse light; indoor tank minimizes heat loss.
2. Freeze & Overheat Protection: Glycol loop prevents freezing; heat exchanger avoids tank overheating.
3. Pressurized Hot Water: Integrates with household plumbing for strong tap flow.
4. Flexible Installation: Collectors on roof/tank indoors (space-saving, protected).
5. Easy Maintenance: Key components (pump, tank) accessible indoors.
6. Reliability & Durability: Robust design; indoor tank extends lifespan.
7. Significant Energy Savings: Cuts 50–80% of conventional water heating costs.
Product Introduction:
Flat Plate Split Solar Water Heater uses roof-mounted flat plate collectors to absorb solar energy and an indoor storage tank to hold heated water. The two components are connected via pipes circulating a heat transfer fluid (glycol-water mix). Ideal for residential/commercial use, Flat Plate Split Solar Water Heater delivers pressurized hot water while maximizing efficiency and durability.
Technical Parameters:
Flat-plate split solar water heaters can be designed according to customer requirements, with a water tank capacity of 100L-2000L.

Key Technical Features:
1. Split Design: Collectors on roof (sun exposure); Tank indoors (reduces heat loss, protects from weather).
2. Closed-Loop Glycol System: Freeze protection (operates below 0°C); Prevents scaling/corrosion in pipes.
3. Pressurized Storage Tank: Direct integration with household plumbing → strong water pressure.
4. High-Efficiency Flat Plate Collectors: Absorb direct/diffuse sunlight; Copper absorber plates + tempered glass cover.
5. Intelligent Control System: Automated pump operation based on temperature differential.
6. Overheat Protection: Heat dissipation via heat exchanger.
Application examples:
1. Residential: Single-family homes (tank in basement/utility room); Apartment buildings (centralized system with large tank).
2. Commercial: Hotels (laundry, showers); Gyms/swimming pools (shower heating); Restaurants (kitchen pre-heat).
3. Households with High Hot Water Demand: Scalable tank size (300L+).
4. Roof Space/Weight Constraints: Lightweight collectors; heavy tank installed indoors.
5. Aesthetic Requirements: Minimal rooftop footprint (only collectors visible).
