6 Types of Solar-powered Hot Water Heater
Many environmentalists definitely and strongly prefer the installation and usage of eco-friendly mechanisms and alternatives for green living. This is because they contribute less harm to the environment and helps lessen the issues of the environment. Solar water heaters are part of the modern eco-friendly amenities that greatly contributes to the conservation of resources and energy, at least on water, air and land pollution. Solar water heaters utilise and make use of the radiation of the sun to generate water in order to heat water. This makes this amenity economical and eco-friendly. The exploitation of solar-powered water heaters would be a wise choice and it could definitely give a wide range of advantages not only to the ecosystem but to your family and pockets as well.
Solar-powered water heaters come in various types and each of them has their unique features and advantages that might possibly help you choose what’s best for your home and family.
- Active water heater systems
Just like all the common solar hot water heaters, this type of hot water heater system heats water with the use of the sun’s heat. After the heating process, the hot water will be transferred to storage for subsequent use. Homeowners don’t have to worry when sunlight fails to give enough energy the system needs because a backup mechanism is intended to provide additional energy to complete the heating process.
- Direct circulation systems
During cold seasons, hot water heaters tend to less efficient and the water it contains might freeze. Direct circulation systems would generate hot water especially on sunny days, and when cold season arrives, this system would recirculate the hot water it has degenerated to avoid freezing water. This kind of water heater system is best for countries that rarely experience freezing seasons to give the system enough supply of heat to generate enough hot water for recirculation.
- Indirect circulation systems
This circulation system utilises 80 to 90 per cent efficiency heat exchanger. A close loop is usually situated between the storage tank of the hot water and the solar collector panel. The water content would be raised to a higher level and is moved through the array and the storage. The primary disadvantage of this water heater system is its high upfront cost and is usually less efficient.
- Passive water heater systems
The primary advantage of this kind of water heater system is its ability to function and heat water for domestic use regardless of the weather. These are commonly installed in countries with no freeze protection as this can work without depending on the power electricity can give because of its self-supporting attribute.
- Integral connector storage systems
Integral connector storage systems are commonly termed breadbox system because of the way it heats the water. The water will flow in a collector located on a rooftop and the collector appears like a box where he had gotten its term “breadbox”. The heating task is mostly done by the sun as the water is heated in the rooftop direct to the sun’s heat. When it is already heated, it will be transferred to the storage of hot water.
- Thermosiphon systems
This water heater system makes use of the principle that the hot water should stay on top of the cold water. During daylight where the sun is perfectly providing enough heat, the water will be reheated because they usually circulate in an unending loop. The heated water will be then transferred to an insulated hot water storage tank ready for commercial use.
