A solar water heater literally harness energy from the sun. The sun’s core holds enormous energy in the form of radiation, the energy that reaches the earth is considered solar energy. Our ability to convert solar energy into useful , into energy such as heat and electricity. For now, solar energy continues to be the most experimental to manufacturers of household appliances such as water heaters.
There are two basic types of solar hot water heating – active and passive. The difference between the two systems is simple. Active systems use a circulating pump to circulate the water between the hot water storage tank and the solar collector where it is heated. Passive systems generally have no moving parts, good water supply using ordinary household water pressure, or by a process called thermo – siphon.
Active solar water heater system a little more complicated because of the use of circulating pump to move the water around. Active system works, basically the same as the thermo – siphon passive hot water heater, but because the pump is used to move water around the storage tank system can be anywhere it would be easier to place. There are both open and closed systems. In an open system, water is pumped directly through the solar collector. In a closed loop system antifreeze solution is pumped through the solar collector where it is heated, and then through a water storage tank, heating the water. Active closed loop solar heating system is more expensive to install, but can be used in cold climates.
A very simple passive water heater can be constructed from a plastic milk jug. Only the black paint , or enclose it in a black plastic garbage bag and fill it with water. The black color will absorb sunlight , transfer to the water using a process called thermal conduction.
Passive solar hot water heating systems are typically used to preheat the water before it goes into the hot water standard . This can cut water heating operating costs dramatically, because the heated water is entering the hot water and not much energy is needed to heat the water.
Another type of passive solar hot water heater is thermo – siphon . In this case , the solar collector sits at a lower level than the storage tank . The sun heats the water in the collector and rise, flowing through a pipe to a storage tank . Water continuously circulates in the system. A variant is using antifreeze in the solar collector, which is circulated back through the tank in a closed loop. Antifreeze solution heat water in the tank and back to the collector to be heated again.
Passive solar water heater system has shortcomings because it can not be used in cold climates because the water is exposed to the outdoors. Only the system thermo – siphon covered can be used in cold weather , because only antifreeze solution in the collector exposed to the weather.
There is sure to be a solar water heater according to your requirements. Using solar energy to supply part of the energy needs of the home in addition to the environmental impact is very big and friendly and cost-efficiency – is a promising future. A solar water heater can mean a one-day future.
The water heater at home – If your home needs supply of hot water, you might be shopping for a new hot water heater before you know if it necessary. You not only need to consider the option of your water heater, you should think about your septic system and how the two work together to make your home a comfortable place when showering. There are a few things you need to consider, careful research you will pay for electricity. You can make the choice that is cost effective, convenient to your home, and just right for your family’s water needs.
The first thing you need to determine is how big the tank is required. This will depend on the size of the house and how many people will use it. While the small size of the tank is usually suitable for home one bathroom, it would be greater if there were six or eight people who live at home and have to share the bathroom. Take into account how often you host visitors in your home, too. If the tank is suitable for two or three family members, but you often have guests on that until the number of users for five or eight people, the size of a large tank may be better.
Further, a comparison of brands water heater available. There are many good choices, so look at the cost and brand reputation respectively. Remember that the cheapest and the most expensive is not always the best choice. Just because something is big does not mean it will suit your needs. The same goes for the most expensive option. Narrow your choices to a reliable brand and look at the features of each series. Once you have made your choice, you have a new water heater, ask the installation. Even if there is an extra charge. This guarantee will be working to full capacity and save energy as much as possible.
When evaluating your options, consider how to make a model, or a different size will affect your electric and water bills. There’s nothing worse than thinking you’ve got a lot of features on reliable equipment, only to find a utility bill doubled from time to time. If you can save money in the long run, the initial investment is worth it.
Finally, consider a tankless option. It allows you to heat only the water needed for a particular location. Instead of warming forty of fifty cubic feet of water, you are dealing with only a few gallons needed per use. This will save you water and electricity bills at the same time. They are more expensive, but often worth the investment if you can save big from time to time.
