Solar Batch Water Heaters

solar batch collector

Solar batch water heaters are thermal solar collectors heated by the energy from the sun. Batch-type solar hot water heaters are among the most cost effective and simple to construct and use solar device. They can be used alone to provide hot water at temperatures which can fluctuate with the time of day and weather, or they can be used to preheat mains water water feeding into an existing water heater to reduce the fuel costs of bringing the cold water upto a preset temperature. Solar batch water heaters can be as simple as a series of pipes inside a glazed and insulated box to collect the solar energy, or large tanks configured for pumped circulation of anti-freeze heat transfer fluid

Solar Thermal Energy

solar thermal energy

Solar thermal energy uses the suns energy to heat water making solar thermal a viable solution for any future renewable energy heating system. As solar power is the main source of energy from the sun, different technologies exist in the form of solar heating and solar thermal power generation to reduce our dependency on more conventional fossil fuels. Solar thermal energy has a lower environmental impact, zero CO2 emissions or produce other toxic gases like the ones used to produce our current energy production. Solar domestic hot water systems use the sun’s energy collected by flat-plate solar collectors or tubes to transfer the suns heat to water or another liquid

Solar Flat Plate Collectors

solar batch collector

Solar flat plate collectors capture and use the suns thermal energy to heat water or other such working fluids. Solar thermal water heating, commonly known as solar hot water, has a long history of use around the world going back many centuries. Solar water heating systems use a system of solar flat plate collectors to capture sunlight to heat a fluid that is then transferred from the collector to a storage tank. Typicaly solar thermal collectors consist of a rectangular box with a glass or transparent top to capture the solar radiation and minimise system heat losses allowing it to operate at high temperatures and efficiencies over a range of operating conditions

Solar Pool Heating

solar pool heating

Solar pool heating system uses solar thermal collectors to collect and absorb the sun’s radiant heat energy and transfers this energy to the swimming pool water which is being pmped through the collectors. Solar pool heating systems are designed to use the free and renewable solar energy providing a cleaner energy alternative to conventional fossil fuel based pool heating sources which pollute the environment. The advantage of heating a pools water is an increase in the time throughout a year your swimming pool can be comfortably used.

Solar Dish Collector

solar dish cooker

Solar dish collectors are parabolic shaped concentrators very similar in appearance to large satellite TV or radar dish making it much smaller than the longer trough collector. The curved parabolic shaped dish makes use of the direct solar radiation for heating at its focal point and is the main solar component for this type of solar heating system. Concentrated solar power technologies using parabolic dish collectors are perfectly suited for generating high temperatures for applications where extreme heat is required as other renewable energy systems are not able to create such high temperatures.

Parabolic Trough Reflector

parabolic trough collector

Parabolic trough reflectors concentrate the suns solar radiation to increase the efficiency of a solar thermal system. Solar energy can be too diffused and not very dense resource so it is sometimes necessary to concentrate the suns rays to produce high enough temperatures which can then be used for the production of hot water or a working fluid for electrical energy generation. Parabolic trough based solar systems are a type of solar concentrator which have a parabolic curve and are placed together in a straight line to maximise their effectiveness.

Integral Collector Storage

solar batch collector

Integral collector storage systems use large diameter heat tubes inside an insulated and glazed box collector combined with a storage tank as a single thermal unit thus acting as both a collector and storage unit. Passive integral collector storage ICS systems used for solar water heating requires no pumps, controls, or electrical energy consumption for its normal operation thus can can potentially heat water at a much lower cost then conventional active solar thermal heating systems.

Evacuated Tube Collector

evacuated tube collector

Evacuated tube collectors use advances in vacuum technology to heat liquids to high temperaters within a glass tube. The thermal performance of evacuated tube collectors is more superior to other more common solar therml technologies such as flat plate collectors and solar troughs. As solar conditions vary throughout the year depending on time and location, the presence of a vacuum between the absorber plate and the outer glass tube results in a substantial improvement in the solar collectors efficiency due to reduction in heat loss through convection and conduction.

Solar Thermal Energy

solar thermal energy

Solar thermal energy uses the suns solar energy to heat water or other such liquid providing lots of hot water and space heating for the home making it a viable solution for a future renewable energy system. The solar thermal potential of the sun as a continuous heat source makes it an excellent choice for powering alternative energy systems thus reducing the consumption of fossil fuel energy sources and renewable energy fuels such as biomass. Then solar thermal energy technologies have the potential to be a major contributor to the global energy supply
