What are Passive Solar Water Heaters?
Passive solar water heaters are a lot more popular than you might believe. The problem is that a lot of people do not actually know what they are. You might see a big tank somewhere around the house and not even be aware of the fact that it is a part of a passive heating system. So what does passive solar system actually mean.?
Passive solar technologies are basically ways to achieve energy through the use of sunlight and no extra mechanical system addition. This appears in contrast with active solar technologies. This is one type of technology that is really useful in converting sun energy into heat in order to be used for heating 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. Alternatively passive cooling can also be utilized and all is based on the same principles but with opposed goals. 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. One really simple fact revolves around the use of convetional energy. If it is utilized in order to power fans or pumps then we are in front of an active system. 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. There are heating system that are based on using a thermosiphon, thermal mass or phase-change materials. In wider spreads technology that is used in passive solar systems also include solar furnaces or solar forges. These are systems that do need an external energy source in order to align receivers or concentrating mirrors. In wide spread use they are actually pretty ineffective. The proper way for you to implement any passive solar system is by using low grade energy needs.
