Solar thermal systems

Solar thermal systems are useful in many homes for several different options. There are many ways to get solar thermal systems to work in your home and it is important to look into available options that will help to lower the costs of energy consumption needed to heat water or a space. There are two main types of thermal systems that use solar power and those are the passive and active systems. Passive systems allow the heat to be absorbed and are naturally distributed amongst the system while active system will use different means to power the collected heat through the system by using pumps or other devices (which can also be powered by solar energy).
Many of the passive solar thermal systems will be used for water heating and will make it possible to heat a large amount of water then naturally disperse it to other locations. One of the most used options is through solar vacuum tubes which will produce movement of the water as it heats and will make it possible to heat the water in a pool or to save in a reservoir which can contain up to 50-80 gallons of water in reserve until needed at a nice temperature. You may have already seen this type of thermal system in a normal water hose which can hold water in it even when shut off. The heat of the sun will heat up the water and that water will be significantly hotter than the water that will be displacing it for a few seconds to a few minutes.
Several active solar thermal systems also exist and will force the water into the solar heated elements. This makes it possible to get hot water when needed providing that there is enough solar energy transferred into the system to keep the water warmed up. These are often closed systems because they will not interact with the water used by the household but the water is heated through the system to provide nice warm and hot water options to the household. These systems are often filled with an antifreeze agent to prevent freezing during cold winter months. This helps to prevent the system from causing freezing which could stop water flow.
Open systems are also available but make it impossible to control the water flow if the system freezes. Usually the open systems are more suited for locations that have moderate temperatures all year. The most likely places to use an open system would be as close to the equator as possible. This allows for warmer temperatures year round and will prevent freezing over time. Of course there are ways to use open systems in locations where freezing could occur through the use of external heating sources or simply switching to another water heating source during the fall and winter months.
Regardless of why you are using a solar thermal system, it will help to lower your water heating costs and save you a large amount of money every year. The systems will usually be able to pay for themselves relatively quickly and can be installed very easily. Professional installers of solar thermal systems can make the process all the easier with precision installation and making it possible to use the systems almost anywhere. It is possible to use a solar thermal system in conjunction with other solar power devices to help reduce your carbon footprint on the earth and make use of renewable energy sources that are both healthy for the environment and cost effective for what they are meant to do.
