How do solar water heaters work?

1. Energy Collection: Sunlight, short wave energy, is collected and converted to heat which is long wave energy.

The solar collector is mounted on or near your home facing south. As the sunlight passes through the collector's plastic or glass "glazing," it strikes a metal or rubber absorbing material. This material converts the sunlight into long wave heat, and the glazing prevents the heat from escaping like a greenhouse. It is like leaving a car parked in the sun with its windows rolled up. The temperature inside a glazed solar collector on your roof can easily reach 300°F when there is no heat transfer fluid flowing through it.

The most common types of solar collectors used in solar water heaters are glazed flat plate collectors. A glazed flat plate collector consists of a shallow rectangular box with a transparent plastic or glass "window" covering a flat black plate or selective "Chrome" coating. The black plate is attached to a series of parallel tubes or one serpentine tube through which water, or other heat transfer fluids pass.

2. Energy Transfer: Circulating fluids like water in an "Open Loop" or Propylene Glycol in a Closed Loop" transfer the collected energy in the form of heat to a storage tank.

Heat energy is transferred from the collector to the water storage tank. In some water heaters, hot fluid is pumped from the collector to the storage tank. The pump is powered by electricity that either comes from an electrical wall outlet or a small photovoltaic module located beside the collector.

3. Energy Storage

Solar-heated water is stored in an insulated tank until you need it. Hot water is drawn off the tank when tap water is used, and cold make-up water enters at the bottom of the tank.

Solar water heaters tend to have a slightly larger hot water storage capacity than conventional water heaters. This is because solar heat is available only during the day and sufficient hot water must be collected to meet evening and morning requirements.

EXTERNAL DIMENSIONS-SOLAR COLLECTOR

Product Features

• The technically advanced Tianke Energy Saving solar water heaters are closed circuit systems of natural circulation. The special thermal fluid propylene glycol, used in the closed circuit, enhances the performance of the unit, protects it from frost and prevents salt scale deposition inside the tubes of the collector. The closed circuit (jacket) where the thermal fluid is circulating is independent and does not communicate with the water storage tank.
• Simple assembly: Collector and the storage water tank can be installed together
  or separately at your request. It beautifies the building and integrates the solar water heater system to the building.
• Convenient Usage: The storage water tank withstands water pressure,utilises automatic water supply, an automatic controller and the supply of hot water at all times.Sunlight, electricity and gas can work together or there is the option to switch between power sources. The temperature control and automatic operation ensure the supply of hot water throughout the whole day, thus utilising a perfect combination of the solar water heater, the electric heater and the gas heater.
• Double circulation and double withstanding pressure: The medium circulation is separate. Multi-valve protection provides higher reliability, more stability and longer service life.
• Higher efficiency: Heat transmission via advanced medium. With anti-corrosion, anti-freeze, anti-precipitate and high boiling point features, etc.

Ultrasonic Welding Fins and copper pipe are welded adopting ultrasonic welding technique, this ensures good heat conduction, nice outlook and wide usage. The strong welding line can endure different climate. The selective electroplate coating: has high heat conduction and long service time. Application Range: used in manufacture whole copper collector core, flat panel, solar heat-pipe, U-shaped tube and all kind of efficiency radiator etc.

All Copper core Adopting ultrasonic welding, heater pipe and secondary pipe are welded directly without any joints with a beautiful shape. It can withstand cold/hot impact and endure pressure more than 1.4 Mpa. The high-quality selective coating or electroplate black chrome has high absorbance, low emittance, fast heating, anti-corrossion, and long service life features. Application Range: widely used in all dimension solar collector module.

All copper pressurized conjunction:
Used the high-technique hard connection insted of the traditional soft-connection.
The metal sealing loop avoids the leaking problem due to rubber aging.
It makes installation and usage more convenient and reliable.

Ti-Nano titanium nano-coating technology

The most usual problem that might occur in a solar water heater is the appearance of rust inside the water tank and also the formation of scale that can destroy the electrical backup heating element. One of the most used techniques used to overcome this problem was the application of a glass coating on the inside of the water tank that would prevent rust formation.

This technique however has one major problem. Glass and steel have different expansion properties. Therefore the steel tank would expand with a different rate than the glass coating causing cracks in the glass surface. Even the smallest crack can create a rust spot that will contaminate the water.

Tianke Energy Saving seems to have overcome this problem with the application of a different type of interior coating which they call Ti-Nano coating. This titanium based 200µm nanocoating has been used in boat water tanks and also in the army's water supply tanks. This material is also used in industrial chemical tanks and transfer pipes and provides rust and corrosion resistance for more than 60 years even if used to store acid or alcaline materials. It also prevents the formation of scale or any other deposits on the surface of the coating and is suitable for the storage of food and water. Also since it is a nanocoating technology it invades the pores of the steel tank and is impossible to crack or wash off the steel surface of the tank's interior.
