So collectors without corrosion and circulation fluid leaking; 5.The solid built-in absorber plate can absorb all solar radiation improve working efficiency and integrated well with buildings.
It is a kind of tankless, lager-caliber tube and low-pressure solar water heater system with the following features The system contains 4-8 pieces of vacuum tubes as one unit, with each tube capacity of 16 liters of water. this one is 5 pieces of vacuum tubes as one unit. Inside each tube, there is a high-temperature-resistant and corrosion-resistant stainless-steel cylinder made of food-grade 304/316 material, so the solar heater does not require a water tank like other products in the market, thus saving space. the heater is pressurized. It is connected to the tap-water supply system and on the other side it is connected to the shower head in the bathroom, so the pipeline is relatively simple, and the installation and maintenance are also simple and convenient. Because this water heater is connected to tap-water supply system(pressurized), it can be installed anywhere for buildings, such as on the ground, the roof, the balcony, the terrace etc., whether high-rise building, multi-story building, bungalow or villa. Each tube is equivalent to a thermos bottle, which has good insulation performance, and there is air between the steel cylinder and the glass tubes, which also provides the added thermal insulation. and the tube openings are also insulated by good materials, ensuring optimal heat retention. Based on our experiments conducted on the rooftop of an eight-story building, with daytime temperatures reaching 7C and nighttime temperatures dropping to -3C or -5C, it is observed that when 15C water was injected at 9 AM, the water temperature ranged from 51C to 64C at 17:00 PM. The following morning at 8 AM, the water temperature ranged from 42C to 47C, and by 17:00 PM, the temperature of the hot water reached 85C.
Product Description It is a kind of tankless, lager-caliber tube and low-pressure solar water heater system with the following features: Capacity: The system contains 4-8 pieces of vacuum tubes as one unit, with each tube capacity of 16 liters of water. this one is 4 pieces of vacuum tubes as one unit. Tankless: Inside each tube, there is a high-temperature-resistant and corrosion-resistant stainless-steel cylinder made of food-grade 304/316 material, so the solar heater does not require a water tank like other products in the market, thus saving space. Pressurized mode: the heater is pressurized. It is connected to the tap-water supply system and on the other side it is connected to the shower head in the bathroom, so the pipeline is relatively simple, and the installation and maintenance are also simple and convenient. Flexible installation position Because this water heater is connected to tap-water supply system(pressurized), it can be installed anywhere for buildings, such as on the ground, the roof, the balcony, the terrace etc., whether high-rise building, multi-story building, bungalow or villa. Installation method: vertical, horizontal, inclined etc. installation Limescale prevention: Pre-filter as a standard feature gives an effective limescale prevention solution to avoid any potential worry. Excellent insulation: Each tube is equivalent to a thermos bottle, which has good insulation performance, and there is air between the steel cylinder and the glass tubes, which also provides the added thermal insulation. and the tube openings are also insulated by good materials, ensuring optimal heat retention.

The following morning at 8 AM, the water temperature ranged from 42C to 47C, and by 17:00 PM, the temperature of the hot water reached 85C. The highest energy efficiency: due to its large area of absorption of sunlight, it is with good energy efficient whose hot water outlet is the highest. Automatic anti-freeze function: when the temperature falls below 5 C, the system will automatically activate the anti-freeze electric heating feature. optional devices: electric auxiliary heating pump station, gas water heater, electric water heater can be added to our heater system as auxiliary components to be used if weak or lack of sunlight. Customers can choose one out of above-mentioned three.
