Passive water heaters using solar power are really popular nowadays. 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 how can we define a passive solar heating system?
Passive solar technologies stand out as ways in which you use sunlight to gain energy without the extra addition of mechanical systems. This is definitely appearing in contrast if we look at solar technologies that are active. This technology type will help a lot in converting sunlight to heat so that you can use it with different purposes. The fact that is interesting is that energy sources that are extra will only be minimally required or not at all required.
We can give an example that is quite common in solariums built on South 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.
Keep in mind that a common mistake is thinking that one passive solar heater system is an active solar water heating system. A basic rule of thumb revolves around using conventional energy. If pumps or fans are powered with its use then the system is an active one. Different passive system will also utilize conventional energy but only a small amount of it.
Passive solar water heating technologies will also include different indirect and direct space heating aimed solar gains. Different heating systems exist. Some are based on thermann mass while others on phase-change materials or thermosiphons. In wider spreads technology that is used in passive solar systems also include solar furnaces or solar forges. These systems are to need extra energy sources so that receiver alignment and mirror concentration can be achieved. In wide spread use they are actually pretty ineffective. The best way to implement passive solar systems is through the use of low grade energy needs.
