What does a cover on a solar water heater do?
If by cover you are referring to a slip-on or wrap around 'blanketing' that surrounds the heater tank, its purpose is simply to reduce the amount of heat energy transferred to the air from the tank, reducing the amount of water that must be circulated through the collectors, and keeping the water hotter longer, for when there is no sunlight to warm it, (although almost all units have electric backups, the purpose of a solar heater is to not use electricity). It's basically just insulation.
If you are talking about a cover for the collectors, it could serve a number of purposes; protection, amplification, insulation, etc. There are some that direct solar light toward the collectors at the most efficient angle regardless of the position of the sun; It just has to be visible.
Solar water heaters do three basic operations before the hot water comes out of your faucet:
1. Energy Collection: Sunlight, short wave energy, is collected and converted to heat which is long wave energy 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.

What are solar water heaters?
Solar water heaters are devices that are fashioned to let watercollect the energy from the sun. You can make your own or purchasethem already made. They are typically dark in …color to absorb themost amount of energy from sunlight. They often have pumps hookedup them to circulate the water through them. One use would be toheat the water in a swimming pool. They are also used to pre-heatthe water that comes into your home/office water heater. They canalso be used to heat water directly for bathing or cooking.

Why was the solar water heater invented?
I am not really sure when solar hot water was invented. It is the sort of thing that is so easily conceived that it could have been done in the nineteenth or even eighteenth c…entury. It could have been invented by different people in different times. The earliest solar hot water that seems to be well documented is its use in southern California in the 1920's. In much of the rest of the country, hot water was often prepared as a byproduct of heating or cooking with wood or coal. Since heating was not a constant problem in southern California, and cooking was often done outdoors to keep kitchen heat out of the house, hot water was a separate issue. There was so much sunshine there that it seemed a shame to use fuel or electrical power to heat water.
What are advantages of solar water heater?
Saves alot of money on electricity. Gets very hot.
What are the disadvantages of solar water heaters?
i think that they would probably not work without the sun and in addition to this i dont think they would make us much heat as the other heaters eg convectional heaters
Why do solar heaters use water?
Solar heaters are meant to heat the water for your house or in a pool, so you need water to heat it! The water runs through a system where it is put onto the roof of your hous…e, for example, heated by the Sun and then stored or put into your pool.

Do solar water heaters work?
Solar water heaters perform three basic operations before the hot water comes out of your tap: 1. Energy Collection: Sunlight is collected and converted to heat energy. Th…e solar collector is mounted on or near your home facing south. As the sunlight passes through the collector's glazing, it strikes an absorbing material. This material converts the sunlight into heat, and the glazing prevents the heat from escaping in a similar manner to 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 150°C when there is no heat transfer fluid flowing through it. The two most common types of solar collectors used in solar water heaters are glazed flat plate and evacuated tube collectors. A glazed flat plate collector consists of a shallow rectangular box with a transparent glass "window" covering a flat black plate. The black plate is attached to a series of parallel tubes or one serpentine tube through which air, water, or other heat transfer fluids pass. An evacuated tube collector consists of several individual glass tubes, each containing a black metal pipe through which the heat transfer fluid passes. The space between the pipe and the glass tube is "evacuated," so the air is removed. Although uncommon, unglazed plastic collectors can be used as a seasonal solar water heating system. However, they are used mostly for pool heating. Each collector has its advantages, and each can perform well if matched with the proper, well-designed, storage unit. 2. Energy Transfer: Circulating fluids 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. In other types of solar water heaters, the sun heats the storage tank directly, so the fluid in the collector is heated and rises naturally to a storage tank above the collector. This type of solar water heater is often referred to as a thermosiphon system. It does not require an electric pump. Passive solar and solar photovoltaic-powered systems will continue to operate even if there is a power outage. The products that require electricity from a wall outlet will not operate during a power outage. 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.

How does solar water heater operate?
Following are the elements of a solar heating system for hot water: 1. Automatic solar controller 2. Temperature sensor on collector 3. Temperature sensor on storage tank 4. S…olar circulation pump 5. Cold water inflow 6. Hot water run-off 7. Expansion tank 8. Temperature sensor for additional heating 9. Charging circuit- solar circulation pump Solar collector is the main part in solar heating system and ismade up of a selectively layered absorber that serves to absorb theincoming solar radiation and transforms it into heat. This absorberis embedded in a thermally insulated box with a transparent coverto minimize the thermal loss. A heat conducting liquid flowsthrough the absorber and circulates between the collector and thewarm water storage tank. Thermal solar energy systems will bebrought into operation through a solar automatic controller. Assoon as the temperature on the collector exceeds the temperature inthe storage tank by a few degrees, the regulator switches on thesolar circulation pump and the heat conducting liquid transportsthe heat received from the collector to the storage tank. The conventional heater guarantees, with the charging circuit, thatenough warm water will be available even when the solar heatingsystem supplies little or no heat at all. Solar heating systems canbe integrated into buildings without a problem. There are 3 types of collectors: 1. Batch collectors 2. Flat-plate collectors 3. Evacuated tube collectors
