The bigger the difference in temperature between the items, the heat movement will be faster. Heat Movement Assessment It is important that people know more about the movement of heat to full appreciate solar thermal energy. Passive solar energy applications use a lot of heat movement. The 3 common physical ways that heat moves include convection, conduction and radiation. Also, the Greek s use of solar energy were not limited to religious purposes, as they even used the solar energy system to incorporate passive solar design in the construction of their houses. The Romans simply improved the Greek s design and also incorporated windows into their structures, allowing them to be able to trap more solar heat. Direct systems heat the current household water in solar collectors. Water is pumped to a tank after heating. Indirect systems use heat transfer fluid. The fluid is heated in solar collectors, then pumped to a storage tank. This is also known as a closed-loop system. The Third Type Active solar pool heating involves the use of pumps to properly circulate the water in the pool via solar collectors to heat and then return to the pool. And with the introduction of different photovoltaic integrated products, and incorporating them into the construction of your home, or your work place, you can actually save a lot just from the initial cost of construction as compared to building a conventional custom house. Solar Pool Heater If your home, or work place, has a pool, then a solar pool heater is needed to keep that pool heated at a certain temperature. The trend can continue to provide benefits for decades to come if well-maintained. Here are some more tips and tricks. About Location First, you have to consider your current location. Are there a lot of clouds or does it rain or snow frequently? How much sunlight do you get per day? Some locations are very ideal for installing solar cell panels, while other people may do better with an electrical or battery source. Solar Energy in the House Solar energy is described as power coming from sunlight. It is a very economical way of getting energy needed for different household tools and devices such as lighting, power tools, appliances and other gadgets. You can save more in the next few decades by investing in solar power.
