Introduction
Domestic hot water solar heater system is one of the home appliances which are reliable, adaptable, and cost effective. Since energy is renewable, it is a wise investment for every home owner to install it. They are various reasons for investing in domestic hot water system which includes; environmental friendly, reduction on utility bills and eligibility for rebates and incentives.
Return on investment depends on the site of installation, utilization pattern and fuel replaced. In state like Washington and CA, returns on investment have become increasingly attractive with rise in prices of convectional energy.
Operation of the System
The water heating using the gadget is a thermodynamic process which requires well coded heaters with better buck up system through qualified installation and coded programmes.
Domestic water heating system consists of the following parts; solar collectors, a closed-loop, insulating piping system and a storage tank. Maximising solar absorption collectors are placed on an un-shaded areas of the roof facing south at 30-60 degrees angles. Solar panels can be installed on roof tops, building terrace and open grounds. Solar water system generates hot water on sunny days, moderates hot on cloudy days and not on rainy days Stainless still are used for small tanks, whereas in enormous tank mild steel with anti-corrosion coating is used.
Flat plates collector (FPC) compost of insulated black metallic boxes which enables them to transfer the natural solar radiation into the flowing water to initiate conventional currents movements in the tanks .
.
Storage tank is directly proportion to the collector. In Washington and CA most pools are used between 6 to 8 months. Therefore the system systems are typically sized at (60%-70%) of the pool surface area.
According to research the whole system can cost $5000 to $6000. Therefore closer attention is required to maintain the appliance. Due to wear and tear of components, the qualified service technicians are necessary over a given period of time before installation of a more efficient infrastructural one.
Types of the Solar Water Systems
The main types are; Closed loops and open loops, in closed loops, Heat exchangers are installed to protect system from hard water whereas in open loops, at a single region the atmospheric is condoned to inflow. These are relatively inexpensive and are suitable for domestic .
Economic Benefits of the Domestic Solar Water System
Cost Effective
Researchers have found that it is one of the economical ways in modern life. Most economic advantage is that sunshine is free. Fuel saving research shows that a 100 litres capacity of solar water heaters can replace 1500 unit of that electricity annually. This saves around $150 to $400 per year on fuel bill, Thereby protecting an individual from unnecessary inflation of fuel prices of other convectional energy over time. This means hiking prices of gas and electricity depending on the period have zero implication to an individual .
Environmental Friendly
Solar energy is environmental friendly compared to other sources of energy, that is, fossil fuels which produce carbon IV oxide emissions. Viable sources also indicate that its life span is durable enough to about 15 to 20 years this is an indication on global warming save.
Property Value
If one is real estate developer installation of solar hot water system leads increase in resale value of property.
Tax Free
After initial installation period, energy is tax free depending on the amount of water used and this saves the utility bill.
Manufacturers of the System
The reputable institutions with are renowned in installation and project development in U.S.A includes; The Florida Solar Energy Centre, Nelson Mechanical Design and Ergard Energy solution in North Carolina.
Conclusion
The optimal configuration and centralized installation improves efficiently in supply of preheated water for entire home. Using solar water systems offset energy cost over time. Large solar systems offer great return on investment than those designed for smaller domestic areas . Solar system is conventionally less expensive than the cost of gas or electricity system, this implies improved living standards, for home installation one need to consider association rules and neighbourhood by-laws known as Codes, Covenant and Restriction (CC&Rs)and ensure that have ordinances or permits for home improvement like system installation.
