Types of Solar Water Heaters and Solar Water Heater Reviews

 You will find Solar Water Heater Reviews on our site that may help you to decide the right system for your residence.

Evacuated Tube Solar Collectors

An evacuated tube solar collector is engineered to utilize an evacuated tube to convert solar energy into usable heat, which is very helpful in household usage such as pool heating, hot water heating and even air conditioning. This type of solar water heater comes in various sizes depending on the needs of the whole family. The main component of this type of solar collector is the evacuated tube because it is responsible for the conversion of raw energy from the sun into usable heat. A typical evacuated tube solar collector is composed of several evacuated tubes with borosilicate glass shells that use a vacuum space to provide heat loss protection. When solar energy is captured in the tube, it needs to be preserved inside to prevent solar wastage.

The vacuum-sealed glass tube takes hold of the solar energy, speedily heating a particular non-toxic heat-transfer fluid in the copper heat pipe. Then, the heated fluid ascends to the topmost area of the pipe, wherein the fluid already heats up the water. The water is in circular motion with the help of the copper inside the insulated aluminum header. Once the heat-transfer fluid cools down, it returns to the bottom of the heat pipe to be heated again. The cycle continues as long as there is an ample amount of solar energy. For the evacuated solar collectors, Rheem can you your choice as per our solar water heater reviews.

The primary features that an evacuated tube solar collector should mostly have (but not all) are the following: The device should be easy to maintain or it must possess minimal maintenance so that you may not have a difficult time in keeping the collector in its stable position from time-to-time. It must have the necessary evacuated tubes with glass shells that are reliable and efficient to trap the solar energy.

It must have an internationally recognized seal indicating that the product is certified and tested. Otherwise, you may end up wasting your money in non-certified products, which may also impose risk in everyone’s health and inside the household. This type of collector should have copper heat pipes in order to transfer the by-product rapidly.

This collector should have a stable solar conversion or a passive tracker that can capture solar energy all-throughout the day. Evacuated tube solar collectors are perfect for domestic use due to its easy first-time plug-in installation, which is important in providing the family the ease in its usage. It is also ideal for commercial use since it has a wide range of sizes that can accommodate large business requirements.

Flat Plate Solar Collectors

A flat plate solar collector harnesses the solar energy to be converted into usable heat for commercial and domestic usage, which is takes on a great effect in reducing electricity cost. This type of collector is coated with a specialized material to intensify the absorption of solar energy.

It is usually a metal box with a plastic or a glass cover, depending on the model that you choose. The cover is placed on top of the box, and a dark-colored absorber plate is placed at the bottom. It is manufactured to look like a box so that it can be easier to mount it on the roof for easy access of solar energy.

The most important element that the flat plate solar collector is known for is the absorber plate because it is tailored to shroud the whole box in order to do three major functions: to absorb as much solar energy as it can receive, to convert the raw solar irradiance, and to deliver the converted heat to the household. An absorber plate is mostly painted with carefully, selected coatings to effectively absorb the heat, compared to painting the plate with some ordinary black paint. The absorber plates are comprised of either copper or aluminum with the best properties of being a good heat conductor. It also has insulation embedded in its technology so that heat loss can be reduced and heat is returned back to the collector. The flat panel collector system Sunchaser stands at the top on our analysis of the solar water heater reviews.

The chief aim of this type of solar technology is for the usage of residential buildings wherein the demand for hot water is greatly manifested, especially in electricity bills. This also derives that it is suitable for large families or businesses that require hot water in their daily routines or in their frequent household chores. Commercial activities like car washing, eating establishments and laundry facilities usually require hot water, and businesses alike often necessitate solar water heaters that can accommodate large capacities of hot water in minutes. A flat plate solar collector is cost productive because it effectively lessens the expenses in the bill.

Drainback Solar Water Heating System

A drainback solar water heat is a closed-loop, active, indirect system that is manufactured to have freeze protection. The heat-transfer fluid (HTF), which is usually water, is transferred in an unpressurized, closed loop, and is pumped through the collectors. The HTF is separated from water that is still being heated in the heat exchanger. When the pump is turned off, the HTF is drained from the sloped collectors and pipe, leaving them protected from freezing.

The important elements of a drainback heating system are the following: A differential controller tracks the water temperature in the collector’s thermometer and in the tank. When the thermometer surpasses the storage temperature set in the number of degrees, the differential controller then activates the heat-transfer fluid pump. Most drainback heating systems have DC pump, powered by a PV module that serves as the controller. The PV module collects sufficient sunlight to start the pump the heat is already ample in the thermal collector.

A storage tank stores the water being heated by the drainback solar water heating system. This can be an indoor pool, gallon tank, or a domestic hot water tank. A reservoir or a tank in the HTF loop plumbing contains the HTF in the collector loop. A gurgling sound is often heard in this system when the HTF is being drained into the reservoir. Air space in the unpressurized reservoir causes the gurgling sound in the system. A heat exchanger is used to circulate the heat between the drainback loop and the unheated water. It is usually found inside the drainback reservoir.

The advantages of this type of solar water heating system can be manifested in its product design and the drainback technology it possesses. The heat-transfer fluid loop is not required to be pressurized due to its requirement of air space while draining the hot water. Pressurized loop plumbing has the tendency to leak more rapidly than unpressurized loop plumbing. An unpressurized HTF loop does not require other materials that most pressurized systems have, thus easy maintenance is achieved. This system does not need electricity to turn on its freeze protection capacity, and it has no motorized valves to maintain. If it suddenly runs out of solar energy in its collectors, the pump turns off automatically and the HTF is drained from the collectors in order to return into the reservoir.

However, the expense needed for the drainback reservoir may draw back the economical savings you have with the equipment of this particular solar heating system. Still, installation process is already simplified due to minimal parts in the device. It also has a glycol antifreeze that is reliable in providing freeze protection. Although, glycol requires extra maintenance because it tends to be acidic when the device overheats often.

Active Open Loop Solar Water Heating System

An active, open loop system is one of the simplest solar water heating system ever engineered, and one of the most economical active system suitable for small households. The system functions at standardized pressure, which means that there is no present heat exchanger. It utilizes pumps to move the water through the collectors, which makes the process very efficient to think about. Heat is transferred directly to the water with no other processes involved. It is that simple.

Active, open loop system effectively lowers your utility bills because of the solar energy it uses to provide you with renewable energy. However, this particular system is not advised to be employed if your water supply is acidic or hard because there is a tendency that scale buildup and corrosion may form and disable the system’s functionalities.

Open loop solar water heating system is an appropriate choice for tropical areas where solar energy is ample. It is unsuitable for open loop systems to be installed in freezing climates in a long period. A recirculation system is a specific type of an open loop system that offers freezing protection. It utilizes system pump to motion heated water from tanks through the collectors and pipes when the temperature becomes cold. Take note that the freeze protection must only be turned on when temperature is really freezing, otherwise, continuous usage of such feature may waste the stored heat.

Open loop systems have a differential controller that monitors the temperature of the solar collector. When the controller detects warmer water than the water at the bottom of the tank by four to five degrees, the controller then activates the pump to circulate the cold water through the solar collector. Its advantage entails its highest operating performance due to its minimal parts and processes, but still capable to heat water.

Passive Solar Water Heating System

A passive system mostly depends on heating pipes or heat-driven convection to circulate water. It is actually cheaper and has very low or no maintenance at all, however, its efficiency in heating water is momentously lower compared to active solar heating system. Moreover, passive systems are susceptible to freezing and overheating.

There are two types of passive solar water heating systems: A thermosyphon system is when warm water arises as cold water sinks. The collector is installed below the storage tank to indicate that warm water still rises into the tank. This type of passive system is reliable but it is required to have special and cautious attention when installed onto the rooftop due to its bulky storage tank. It is commonly more pricy than an integral collector-storage passive system. It has an insulated storage tank that relies on the science of using heat to move water through the system.Solar water heater reviews

An integral collector-storage (ICS) passive system is best utilized in areas with very freezing temperature. It is also dependable in households with high demands of hot water. Cold water goes through normal water pressure at the bottom of the tank while hot water rises on the top of the tank. It is engineered to tolerate freezing temperature. Passive solar water heating systems are among the best-selling heating devices in the matter due to their tailored simplicity and extremely low maintenance feat with no pumps, controllers and other wirings that most heaters have.

Nevertheless, it is still your preference if you want to invest in a solar heating device with the maximum features or the minimal one, as long as the solar water heater you prefer fits your requirements at home.

Anti-scale buildup

Some solar water heaters form scale buildup while circulating water through the collectors. Consider solar heating devices with anti-scale formation because scale can minimize the lifespan of the heating process inside the solar water heater. However, investing in a more expensive solar water heater that offers longer lifespan compared to others is unnecessary. You can simply choose a device with a 12-year warranty to cover the damage that scale has produced with your solar water heater device.

Heating source

The heat source that solar water heating devices use is obviously the solar energy. It is a renewable energy and the cheapest heat source ever utilized by man. Electric bill does not need to rise up when you get your energy source from the sun. Electric and gas sources are expensive, and their prices often increase from time to time.

Warranty

Mismanagement of solar water heating devices is sometimes inevitable, that is why a warranty is constructive and relieving for you to use in case your device is not functioning properly. For most solar heating devices, the coverage typically covers three to 12 years. Sometimes, you need to pay more in order to have longer warranty periods. The best choice is to choose a device with the most practical warranty coverage. Once you have a brief idea, please navigate our solar water heater reviews to compare them.

Glass-lined storage tanks

A storage tank is used to store hot water and cold water together. Having the storage tank to be glass-lined, corrosion is reduced that is usually occurred inside the solar heating device. A coating layer is applied to the inner steel of the tank, and is heated to compose a protective, porcelain glass-like layer.

Space requirements

Solar water heaters vary in sizes depending on their capacity. Some heaters are large enough to accommodate heating water for big families, commercial buildings, and businesses, while others are small enough to be positioned on the rooftop for smaller families.

Digital displays

Most of the high-end solar water heaters have digital displays that are helpful in monitoring your preferences and in customizing heating operations. The displays often include tank and collector temperatures, pressure readings and other related data.

Brass drain valves

The valves are utilized to supply cold water to the storage tank, and they are located near the base of the heater device. Some devices have plastic drain valves, usually the cheaper ones. But a brass drain valve is more durable and more stable to use compared to plastic drain valves.

Climate change also cause extinction to some animals due to their inability to adapt forcefully. For instance, the North Pole is the natural habitat for polar bears, and since polar ice caps are melting very fast, their habitat is fading away. The situation leaves the polar bears to swim endlessly looking for icy surface, or to migrate to other places, which may be dry and hot. Of course, most animal are already in the brink of extinction due to harmful human activities that destroy their homes or kill them for food, medicines and other commercial use.

As a concerned human being inhabiting this wonderful planet, our duty includes taking care of what is left and nourishing it in order to preserve the beauty of Mother Nature. Not only does this benefit us, but also for the future generation. What do we have to endow if everything is nearly destroyed? What animals do we share to the future kids if most of the wonderful creatures are gone, vanished and extinguished? Little actions still count even in the smallest way that you can think of. Like for example, owning a solar water heater can contribute greatly to reduce electrical and gas usage, which in turn uses non-renewable, dirty sources like the fossil fuel.

Let us take care of our planet because this is where we are able to live and to survive, and this is our one and only home. Remember, there is no place like home.
