Solar heating systems (solar thermal)
Using solar energy to heat your water is one of the more practical and cost-effective ways to harness energy from the Sun. Solar thermal systems absorb the heat of the Sun and use it for your needs of hot water of the residence of the heat. In General, the solar thermal system be easily heat water 140ºF or higher corresponding to the range of his counterpart traditional hot water tank. Effective systems can collect up to 70% of the energy of the sun which reached their and transfer to you.
Work of hot water heating systems solar how to
In General, there are two types of active water heaters: direct and indirect.
Direct solar water heating
As implied, direct systems capture the sun heat in collectors to directly heat the household water supply. The system consists of collector pipes filled with water and which is related to an isolated storage tank typically located inside a House. As the sun warms the water inside the pipes, the water flows into the storage tank. Although the direct systems are more efficient than indirect, they require more maintenance to keep pipes clear of mineral deposits. Direct solar thermal systems also work best in climates warmer where the system is less prone to freezing.
Indirect solar water heater
Indirect systems does step heat water directly rather than they use fluids with a low freezing point to absorb the radiation from the Sun. Systems closed, also called loop, indirect solar water heating system absorbs the rays of sunlight to heat pipes evacuated of air which in turn heats up to laminated thin copper pipe located at the rear of each stack. The table of the collection consists of several pipe heating which is mounted and tilted to maximize solar collection.
Often glycol (antifreeze ingredient) through adjacent pipes in the table and heats through contact with laminated copper. The temperature in the rise of pipes, heat activates a pump that circulates the glycol fluid in a heat exchange coil in the water tank. This coil, in turn, transfers heat from the water tank and voila, the hot water is produced.
Solar swimming pool and jacuzzi, heating systems
Heating systems solar pool operate on a principle similar to a solar hot water system direct. However, because water can heat too in a solar thermal system, glazing of perception is often removed. The assistance of non-glass pipes or a heating system that resembles a flat matte black prevents the water in the pool become overheated as well as reduced costs for the whole of the system.
While solar swimming pool and jacuzzi, heating often are exempted of the discounts and premiums federal and States, they often pay their own within 1 to 5 years (depending on mainly where you live).
Radiant for your home heating systems
You can also use a water heater solar (or thermal) a system for heating your home. Rather than transfer the water heated to an apparatus for heating domestic hot water, solar hot water system can connect to a radiant floor or a wall panel radiator.
You can make the system of collection and distribution as simple or complex as you like depending on your location, climate and wanted to use. Radiant heating systems more use of the collection table to heat water and store in a tank of high thermal collection so that you have enough heat to last at least through the night. A general rule is to have a collection tank that can store 1½ to 2 litres of water for every square foot of solar collector. That water, in turn, is routed via tubes plastic under floors to create an efficient heating system.
Heating radiant floor have many advantages. They are generally more effective than a forced air heating system of 40 percent and can be zoned so that each room has its own thermostat. In addition, radiant floors distribute heat under your feet where it increases naturally providing a comfortable and spread heated vividly.
Tips for installing solar hot water systems
Tips for cooler climates solar hot water heater
In climates cooler during cold periods of the year, an indirect solar heating system can help reduce your energy costs by working as a system rather than a pure and simple of preheater water heater of the water. The preheated water reduces the load on your other energy systems to heat the water.
Another trick to increase the efficiency of the system is to encapsulate your tank of water with an insulation blanket to keep enough hot water and further reduce the need to rely on traditional energy sources to heat your water. (Note that water heaters not all need a mattress insulation.) Many of the most recent models energy come with a thicker layer of insulation inside the tank which eliminates the need for extra insulation).
Where to put a solar thermal collection system
As other types of solar energy systems, solar hot water heating systems work best on the walls of the South face with the exhibition full sun. Because of the type of collector of construction tubes, exterior elements have less effect on its performance from a system photovoltaic collection; a little shade on thermal table will have a less sensitive effect.
Work with a solar Pro
As with any upgrade of solar energy, consultation with a professional solar energy can help you to assess your potential savings and to determine the type of solar system of hot water which is best for you. Solar thermal panels come from tables of the independent collection and integrated building panels. A solar pro can size your system and help you compare different options for the panels in the collection and the water tank that you need. And don't forget, solar domestic water systems are often eligible for federal, State and local tax credits and rebates!
