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.
