500 Liter Solar Water Heater is a sunlight solar water heater system designed for multiple scenarios. It is equipped with dual-core heating technology (solar energy + electric auxiliary heating). The 500-liter large-capacity water tank can meet the all-weather hot water needs of 8-10-person families or small and medium-sized commercial places. Through the intelligent control of the solar water heater thermostat, the water temperature can still be kept stable in winter.

Product advantages and features

1. Efficient operation in winter

Solar water heater in winter mode: The vacuum tube has a spiral heat-conducting copper tube built in, and with a double-layer antifreeze insulation layer, it can still output 50℃ hot water in a -20℃ environment.

Electric auxiliary heating intelligent start and stop: When the water temperature is less than 40℃, the solar water heater with electric heater mixed mode is automatically started, and the energy consumption is 55% lower than that of traditional electric water heaters.

2. Second-level hot water response

Sun instant water heater technology: adopts a layered heating design, the separation speed of cold and hot water is increased by 50%, and hot water is output in 3 seconds after starting.

Intelligent constant temperature system: water temperature fluctuation ≤±1℃, suitable for solar shower water heater scenes, to avoid sudden changes in water temperature during bathing.

3. Corrosion resistance and long life

The water tank adopts 316L stainless steel liner and passes 5000 hours of salt spray test.

The surface of the bracket is electrostatically sprayed, and the weather resistance is increased by 70%.

Parameters	Performance indicators
Daily effective water output	500L@45℃ (standard lighting conditions)
Winter thermal efficiency	≥78% (-15℃ environment, 3 hours of sunshine)
Electric auxiliary heating power	3kW (automatic avoidance during peak hours, saving 40% of electricity)
Hail resistance level	No damage to 30mm diameter hail impact
Pipeline pressure bearing capacity	0.8MPa static pressure (2 times the national standard)

500 Liter Solar Water Heater 7

It uses a vacuum tube to absorb solar energy, then converts solar energy into heat energy, and transfers the heat to the water tank through the heat pipe inside the vacuum tube to increase the temperature of the water in the water tank, and then uses a pressure tank to apply sufficient pressure to the water. In this way, when people use hot water, they will feel the same power as cold water. The vacuum tube of the solar water heater has a natural tracking ability for solar energy, and it can work normally as long as there is solar radiation.

Applicable industries and application cases

1. Family villa project
High-end villa complex adopts sun solar water heater system. A single 500L device meets the dual needs of floor heating and domestic hot water, saving 32 degrees of electricity per day in winter.
2. B&B and hotel
B&B installs sun powered water heater, with air energy heat pump auxiliary, saving 180,000 yuan in gas costs per year.
3. Medical disinfection scenario
A township health center uses solar shower water heater to supply high-temperature disinfection water. The system stably outputs 85℃ hot water. After replacing coal-fired boilers, it reduces CO₂ emissions by 42 tons per year.
