Build A Solar Heat Exchanger At Home.
A heat exchanger is a device that transfers heat from one medium to another. There are a variety of types of heat exchangers that are possible such as air-to-air,liquid-to-air, liquid-to-liquid . A liguid-to-liquid heat exchanger is used to transfer heat from one liguid system ( often this is water ) to another system.
An example of an application for a air-to-liquid heat exchanger would be transfering the heat from a wood stove ( hot air ) to your homes hotwater tank system. An example of a liquid-to-liquid heat exchanger would be for transfering heat from a solar thermal collector’s heated water loop to a 2nd water loop in your home.
Here is a very instructional video on how to make a liquid-to-liquid heat exchanger yourself at home. There is no sound to the video, but text instructions walk you through the material and tools that you will need to complete the project.
As part of any well rounded education in solar energy, a thorough knowlege of heat exchangers is very important. This is a great way to learn for Free!
There is so much quality information and training available for free, if you know what to look for and where to find it. Luckily we do… If you like this type of diy video such as how to make a solar heat exchanger, let us know. We love to hear from our readers.
