Many of us look at the field of alternative energy and the idea of going eco-friendly as a trend, and one which may be not any longer popular. Although that could be the situation for some individuals, the demand for not only us in the United States to be much more energy aware, but as a global society, continues to be a requirement. This post is not intended to be a complaint of a lot of people not becoming energy mindful enough, rather a chance to evaluate the solar energy alternatives for water heating.
Solar water heating is a realistic option for lots of individuals, and has grown into considerably more of a method regardless of the area of the United States one resides in as technology continues to grow. A very good case in point of this position is to think about Germany. With regard to climate and the accessibility of solar energy, Germany is comparable to Alaska. However, Germany is an innovator in solar energy research, advancement and use. As a country, Germany made the choice to do this, and it is performing nicely for them. Understanding that, the capability for property owners in any portion of the U.S. to take advantage of implementing solar energy, and not only for water heating, is a possibility.
While technologies grows and much more readily obtainable in the U.S., the equipment expenses for employing solar water heating will proceed to decrease, which in turn can certainly make it a less costly option for the regular home owner. Considering the April, 2015 brand new water heater specifications in the United States, the price of the majority of new water heaters has grown. Nevertheless, the brand new water heaters made are going to be even more energy efficient, and that is a positive.
According to SEIA, more than 9 million U.S. household water heaters are changed on a yearly basis. That is exceptional information to producing a more sustainable world. Many home solar water heating systems may be set up in a day.
The 2 forms of solar water heating systems are active systems and passive systems. Active systems take advantage of an electric pump to circulate the water. These are the most typical in the U.S. for both residential and commercial use. Passive systems utilize thermodynamics to move the water. One can find several versions of the 2 main types of systems that we will not examine in this article, although the U.S. Department of Energy has fantastic info about them here.
Solar water heaters are made up of 3 primary components: the solar collector, insulated piping, and a hot water storage tank. Electronic controls could also be included, along with a freeze protection system for cooler areas. Solar radiation arrives at the solar collector, the solar collector absorbs the heat and transfers it to potable water in the system. Flowing out of the collector into a hot water tank, the heated water is accessible and utilized on demand. Either system will offer up to 80 percent of the required hot water requirement of a house or building. A usual household may minimize its CO2 impact by an average of 28 percent then as well.
Sizing a Columbia Solar Water Heater System
Residential solar water heater systems are usually sized comparable to that of a standard water heater, by the quantity of hot water generally utilized. A residence that might utilize 50 gallons of hot water on a daily basis can take advantage of a 2 solar panel system. Water heater installment businesses just like Water Heater Repair Columbia SC have unique methods we utilize to help establish the solar panel sizing for the quantity of hot water necessary on a daily basis, per location.
Parts of a Solar Water Heating System
Solar water heating systems comprise a solar collector, insulated piping, heat transfer fluid, a hot water storage tank, and a system controller. Solar water heating systems operate as follows:
The solar collectors absorb sunlight, causing the fluid inside to heat up.
A controller senses that the collector fluid is hotter than the storage tank and signals a pump to turn on.
The pump circulates heat transfer fluid which carries heat from the collector to the storage tank.
The storage tank holds the heated water which is used as necessary. Auxiliary heating remains connected to the storage tank for back-up heating when needed.
According to the Union of Concerned Scientists, solar water heating systems cost $2,000 – $5,000 to be set up. One can find quite a few state governments and local utilities incentives obtainable also. They have links on their website here with information about incentives. With normal maintenance and inspection, a solar water heater system may last 20 to 30 years with nominal maintenance and costs.
