High-efficiency electric heating element meant to complement solar water heating systems guarantees consistent hot water supply even under low sunlight or overcast conditions. Smart temperature control and corrosion-resistant components help this heater to fit well with solar thermal systems, therefore boosting user comfort and energy efficiency.
Dual functionality allows for backup heating when solar energy is insufficient by operation with solar collectors.
Stainless steel 304/316L housing and titanium-doped coatings resist damage from extended sun exposure.
Energy-saving mode only kicks in automatically when solar heating drops below the desired temperature.
Operating at 800°C–1000°C, high resistivity nickel-chromium (NiCr) heating wire is made of
Thermal efficiency: ≥95% energy conversion rate, 30% electricity use reduction vs. traditional heaters.
Rapid heating (3kW model for 50L water) gets 60℃ in 5 to 8 minutes.
Overheat Protection: Shuts off automatically at 120℃ (adjustable via thermostat).
Dry-Burn Prevention: Built-in water-level sensor cuts power if water is absent.
IP68 Waterproof: Submersible design for direct integration into solar tank systems.
Power Range: 1.5kW–15kW (single/dual-stage configurations).
Voltage Compatibility: AC 110V–240V/DC 12V–48V for global use.
Mounting Types: Flange, threaded, or side-entry designs for easy solar tank integration.
Hybrid Heating: Combines solar energy with electric backup for year-round hot water (e.g., 5kW model for 200L tanks).
Off-Grid Solutions: Powers remote cabins or areas with unreliable sunlight.
Hotels/Schools: Ensures consistent hot water supply for large volumes (10kW–15kW units).
Industrial Solar Loops: Preheats water for steam generation or processing in solar thermal plants.
Cold Regions: Operates efficiently at -20℃ ambient temperatures with frost-resistant coatings.
Solar Synergy: Reduces grid dependency by leveraging solar energy first.
Corrosion Resistance: 316L stainless steel withstands chlorinated water and harsh environments.
Cost Efficiency: Lower operating costs via solar energy prioritization (saves up to 60% on electricity bills).
