The 200L indirect anti-freeze solar water heater system is an environmentally friendly solution that uses solar energy to heat water, and is especially suitable for use in cold areas. Its core features are as follows:
System composition 200L water storage tank with a coil heat exchanger: Stores heated hot water to meet daily needs.
Antifreeze circulating fluid: transfers heat to water through the heat exchanger to avoid freezing at low temperatures.
Working principle Indirect heating:
Applicable scenarios Cold climate:
The anti-freeze solar water heater allows it to still work efficiently in low-temperature environments.
Household hot water: Suitable for home hot water needs such as bathing and kitchen.
Why Choose this anti freeze solar water heater system for Your Home or Business?
For homeowners and businesses seeking a sustainable and cost-effective hot water solution, this system offers unmatched advantages:
Energy Independence: Reduces dependence on grid electricity or gas, providing energy security.
Economic Viability: Lower operational costs over time make it a smart financial investment.
Environmental Impact: Supports eco-friendly practices by utilizing clean energy.
Whether you're in a cold region or simply want to embrace renewable energy, the 200L indirect anti-freeze solar water heater system is a reliable choice for efficient and sustainable hot water heating.

· Dual-Coil Heat Exchanger: Copper primary coil extracts solar heat, while the secondary coil interfaces with domestic water, achieving 85% thermal transfer efficiency.
· Multi-Layer Insulation: Features 50mm polyurethane foam with aluminum cladding, reducing nightly heat loss to under 15%.
· Adaptive Pump Control: The SC-1000 controller automatically adjusts flow rates based on temperature differentials (ΔT ≥ 8°C activation).
· Cross-Climate Valving: Includes pressure-relief valves and automatic air vents for system protection during thermal expansion.
· Solar-Ready Ports: Pre-installed connections for photovoltaic panels to power the circulation pump sustainably.
1. Pump will start circulation when temperature difference between solar collector and water tank reaches the set value.
2. Pump will stop circulation once the temperature difference lower than set value.
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to the water tank by a coil heat exchanger.
5. The solar thermal panel will collect energy from sunlight to heat water; there is electric heating element inside water tank, for backup in cloudy or rainy days.

The 200L indirect anti-freeze solar water heater system stands out as a robust solution for sustainable hot water needs. Its energy efficiency, environmental benefits, and cold-weather reliability make it an excellent investment for households and businesses alike. By following proper installation and maintenance practices, you can enjoy years of uninterrupted hot water while contributing to a greener planet.
