The popularity enjoyed by passive solar water heaters is much bigger than you might imagine. What they truly are is a topic that not many people can talk about. You might notice one big tank inside a house and not realize that it is basically one part of one passive heating system. So what does passive solar system actually mean.?

Passive solar technologies stand out as ways in which you use sunlight to gain energy without the extra addition of mechanical systems. This appears in contrast with active solar technologies. This type of technology will basically help in converting sunlight into heat that can be used for different purposes. The interesting fact is that extra energy sources are either not needed or minimally required. One good example that we can mention is solariums built on southern sides of buildings. While we can even utilize passive cooling, this is one system that has the opposed main goal with the use of a similar principle. It can be used to reduce the cooling requirements we see during summer.

Do not make mistakes and think that passive systems are the same thing as active solar water heating systems. One highly simple fact stands around conventional energy use. If it is used to power pumps or fans then we do have one active system. Different passive system will also utilize conventional energy but only a small amount of it.

Passive water heater technologies based on solar power will include both direct and indirect solar gains for space heating purposes. Heating systems are usually based on the use of thermal mass, thermosiphon or even phase-change materials. Different wider spread technologies included in passive solar use can include solar forges and solar furnaces. These are systems that do need an external energy source in order to align receivers or concentrating mirrors. We did see them to be quite ineffective over past years. The proper way for you to implement any passive solar system is by using low grade energy needs.
