Concentrated Solar Water Heater

In this video new physicist shows you how to build a high efficient solar water heater using zinc sh.

Concentrated solar water heater.

Concentrating solar collectors use shaped mirrors or lens to provide higher temperatures that flat plate collectors. The solar concentrator can use concentrated solar power to offer a hybrid solution for petrochemical oil companies for solar enhanced oil recovery and solar electricity. This paper investigates usage of thermal energy storage extracted from concentrating solar heater for water distillation. Concentrated solar water heaters are more complicated to construct and more expensive however they can be very efficient and great fun to build.

How to make a solar water heater using parabolic trough. Concentrated solar power is a technology that converts sunlight directly into heat. Paraffin wax selected as a suitable phase change material and it was used for storing thermal energy in two different insulated treasurers. Solar water heaters are typically described according to the type of collector and the circulation system.

Heliostats are tracking mirrors that reflect solar energy onto a fixed target. Concentrated solar water heating the key concept in concentrated solar water heating is the use of mirrors or other reflective surfaces to concentrate the sun s rays hitting a large area onto a tube. The process reaches temperatures of up to 400 c. A solar thermal collector collects heat by absorbing sunlight the term solar collector commonly refers to a device for solar hot water heating but may refer to large power generating installations such as solar parabolic troughs and solar towers or non water heating devices such as solar air heaters.

When a solar water heating and hot water central heating system are used together solar heat will either be concentrated in a pre heating tank that feeds into the tank heated by the central heating or the solar heat exchanger will replace the lower heating element and the upper element will remain to provide for supplemental heat. The receiver contains a heat transfer fluid which can consist of water steam or molten salt. Solar thermal collectors are either non concentrating or concentrating. A solar power tower consists of an array of dual axis tracking reflectors that concentrate sunlight on a central receiver atop a tower.

This page concentrates on providing links information and plans for build it yourself concentrating collectors and heliostats. The paraffin wax is receiving hot water from concentrating solar dish. The heat can be used for industrial applications. Optically a solar power tower is the same as a circular fresnel reflector.
