Solar Water To Air Heater (Idea) - Thermal Siphon Method

Solar Water To Air Heater (Idea) - Thermal Siphon Method Tube. Duration : 1.08 Mins.

solar energy solar hot water to air heater idea using thermal siphon With a thermal siphon, no pump is needed. Hot water rises in the collector water tank and that rises because it is now lighter in weight per unit volume because it has expanded from the heat of the sun. The hot water will overflow into the radiator located inside the dwelling. Once it's heat energy is used up, the water becomes heavier and will be cooler which will then sink to the level in the collector to be "recycled" again. Thermosiphon article: en.wikipedia.org Nonetheless, with or without a thermosiphon, a small solar powered pump can also deliver the warm/hot water to the radiator or storage tank, even if its some distance away. I'm still trying to figure out the benefits of this as comparred to a regular solar air heater (ie with the cans as pipes, etc). One thing is that the surface is flat which is perhaps easier to build, though adding fluids into the mix makes things a little more difficult than using just air flow. With the hot water method though, the fluid tube can be sent directly to the "floor area / level" where the air heat (from the radiator) can "rise up more" ; to do this with the standard types of solar air heaters, some type of fan in the design would be needed...a celing fan can be used for circulating warm air in a room. For best performance, the collectors surface should be tilted towards the Sun. You might even want one on the roof and might prefer some kind of water heater ...
