Solar Roof Water Heater: Solar roof water heater is an innovative technology which utilizes an alternative source of energy to heat the water.


Solar Roof Water Heater: Good to know!


This can only not save our electricity bill but it can be used for a long period of time. In the modern lifestyle, the hot water has been used for various purposes.

  • Solar energy is always the best option to heat the water in a natural way.

Solar roof water heater becomes a life time equipment to obtain hot water. Government is ready to offer the loans to bear the cost of the equipment. This is the best option of water heating even in the cold countries.

The barriers in the solar roof water heater are lack of proper information about the technologies, the size of the equipment, cost involved in it and about the maintenance.

  • An Innovative Technology Which Saves Electivity Bill

Solar roof water heater is very simple. Solar collector panels looks like a skylight. There is a solar storage tank where the cold water will be collected.

  • The water which is to be heated is circulated to the solar collectors and the storage tank.

The heated water is collected from the storage tank. When we use the proper solar roof water heater, then it itself can supply most of the energy needed to heat the water. To get the maximum benefits from the solar roof water heater, the solar collector should be provided with a large area so that the solar energy gets properly concentrated to that area.


Solar Roof Water Heater: Things to consider!


The collectors are installed on the flat roof so that the sun light falls directly on the collector. The size of the collector depends on the amount of usage of the hot water.

Active solar systems can be installed on any roof because it weighs less than the normal roof load capacity. This type of solar roof water heater does not require a tank on the roof.

  • But the passive type of solar roof water heater requires a tank on the roof.

Moreover it uses the thermosiphon system. Using this system the warm water is raised and circulated to the collectors and the tank. As the water heats up in the collector, it will become light and is directed to the tank.

  • In the same time the cold water flows to the bottom and circulates through out the system.

This process continues until the entire tank gets heats up. This heated water gets stored in the insulated water tank which can be used on the next day. This solar roof water heater has great absorption area along with the great absorption time.

  • This solar roof water heater has a minimum heat loss.

It is very effective even during the cloudy and winter days. It is very easy to clean. Moreover it does not require any special kind of maintenance.

This solar roof water heater has a very compact size and hence it occupies only a less space. They are made up of high quality stainless steel which provides a high resistance to corrosion and hence provides the durability. But it requires a shadow free area for the installation.


Solar Roof Water Heater: Environment Friendly Technology To Heat Water


Solar water heater is cost effective when compared with the total energy cost. Though it requires a higher investment initially, it definitely helps us to regain our initial investment within few years.

  • They are very important because of their eco-friendly nature.

In order to take the full advantage of this solar water heater, it is better to place them in the south direction. They can operate in any kind of climatic conditions. Performance depends on the amount of available solar energy and the cold water which flows in to the system.

  • A Long Term Investment With The Advanced Technology

Solar Roof Water HeaterDuring the installation itself the user will be provided with the instructions that should be followed for its operation and maintenance. Their operations are fully automatic. The indicator is provided to make the user to identify the malfunction.

Government is encouraging the people to use these kinds of appliances which use the solar energy. They are ready to offer loan incentives for these systems.

It is always a better financial investment on the solar water heater because though it is expensive to install initially, it proves to be a long term investment which can bring back a large potential savings in the future.

Solar Roof Pool Heater: Solar energy is the primary renewable energy source available today for electricity generation. It is the radiant energy that is available to the earth directly from the Sun.


Solar Roof Pool Heater: Watch out!


It seems to be costlier than the fossil fuels. But the cost of solar power installation continues to decline with the growth of the market. The cost of the solar energy can reach the point of affordability when we started to realize the benefits of the solar energy and use it in our home.

Solar water heating systems have been used in many countries like China, Australia, Japan, Turkey, Israel, Austria and Greece. Solar water heating systems have been constructed with the help of renewable energy technologies.

  • Solar roof pool heater is designed to distribute hot water for years.

In a pump circulated system, the storage tank is mounted on the floor below the solar collectors’ level. A circulating pump is used to move water and heat transfer liquid between the collectors and the tank.

We are going to discuss about the close-coupled solar water heating system in which storage tanks are directly mounted above the solar collectors built on the roof.

This system does not require pumps to circulate water since the hot water rises naturally into the tank which is called as thermosiphon flow.

We can also get tax incentives for installing solar roof pool heaters. Solar roof pool heater is the cost-effective application of solar energy in any climate.


Solar Roof Pool Heater: How does it work?


Solar roof pool heater is simple and very good application of solar energy and relatively inexpensive. Solar roof pool heater helps us save lots of money in heating our swimming pool and helps the environment by reducing the emission of greenhouse gases.

The solar roof pool heater includes a solar collector which circulates the water to be heated, a filter which removes debris from water before it is pumped to reach the collector, a pump which circulates water through the collector and filter and back to swimming pool and a flow control valve which diverts the water flow through the solar collector. 

  • The solar roof pool systems use low cost plastic collectors that are unglazed.

The pool acts as a thermal storage for the whole roof pool system. The pump circulates water through the plastic solar collectors. Let us see how the solar roof pool heater works in heating the pool water.

First, the pool water is pumped into the filter where the pool water is cleaned and then pumped through the unglazed plastic solar collectors in which the water is heated.

Finally, the hot water is returned to the pool. The solar collectors can be used to cool the swimming pool water just by circulating the pool water at night during summer.


Solar Roof Pool Heater: Purpose Of Solar Collectors


Some solar roof pool heater includes sensors and a valve which may be manual or automatic. When the temperature of the solar collector is higher than the pool temperature, the valve diverts the pool water through the collector.

When the temperatures of the pool and the collector remain the same, the filtered pool water bypasses the collector and then returned to the pool. The materials used to make solar water collectors are numerous.

The type of the material you will need depends upon for which purpose you need the collector and the climate. If you need the pool water to be heated only when the pool temperature is above freezing, then you can use an unglazed solar collector.

The unglazed solar collectors do not have a glass covering and made of heavy-duty plastic or rubber. The materials are treated with UV light inhibitor in order to make the collectors more durable. 

These collectors are less expensive than the solar collectors that are glazed and they can also work for indoor swimming pools. Glazed solar collectors are constructed using copper tubing mounted on an aluminum plate included with iron-tempered glass covering.

It is expensive than unglazed collector yet works more efficiently in colder weather than unglazed collectors. It can also be used to heat water that is used for domestic purposes. Both types of solar collectors of solar roof pool heater require freeze protection to work in colder conditions.


Solar Roof Pool Heater: Installation Of Solar Roof Pool Heating System


Solar Roof Pool HeaterThe installation of solar roof pool heater depends on several factors which include climate, building code requirements, solar resource and safety issues.

So you need to get the assistance of qualified solar power company contractors to install your system. They must be capable of providing you services in maintaining the system.

The Green-DIY-Energy offers you the best service in installing and maintaining your solar roof pool heater.

Solar Roof Heater: Solar energy is the present, and is very much the future of renewable energy resources, when it comes to utilizing the energy to make the appliances work and conserve the energy resources which are currently being used and are in danger of getting used up.


Solar Roof Heater: This is important!


It is exactly due to this reason that, human beings went in search of energy resources which have the capacity to be replenished and have the tendency to be never ending.

After a widespread search, the researchers arrived at the conclusion that, harnessing the solar energy is the only way to conserve the energy resources and reduce the need for paying the extra amount in order to activate the appliances in your housing.

Solar Roofs is the general methodology that most house owners resort to, in a bid to save energy and also to reduce the electricity bill. The Solar Roof Heater is one such appliance that has made a mark in conserving electricity and also, deliver the best efficiency when it comes to the process of heating.

  • General Mechanism By Which Solar Roof Heaters Can Be Operated.

Generally, the Solar Roof Heater consists of the solar roof which harnesses the solar energy and supplies it to the tank where the water gets heated up due to the heat supplied.

  • The Solar Roof Heaters used to supply heat to the water, does an extremely good job during all seasons.

Though, most people had reservations about the winter due to the absence of sun, the Solar Roof Heater is absolutely at ease in switching to the mode where, a gas or electric booster is supplied to carry out the process.

Thus any type of Solar Roof Heaters comes along with an auxillary energy source. This source shall be connected to a gas or a central heating system which is activated automatically when the water in the tank falls below a minimum temperature which has been preset.


Solar Roof Heater: Make sure!


To ensure that the auxiliary energy source gets activated in a manner of simplicity and ease, the source for this energy sources shall range from the heat produced from a wood stove chimney to the usage of fossil fuels or electricity.

  • Types Of Solar Roof Heaters And It’s Working.

As most good appliances, the Solar Roof Heaters also consist of varied types. Depending upon the sort of circuit, which is involved in heating up the water, the Solar Heaters are divided into direct or open loop and indirect or closed loop solar roof heaters.

The direct type of heaters are very efficient to produce potable water to the collector but their disadvantages extends from the fact that, they are unable to provide overheat and antifreeze protection which is coupled with the fact that it easily allows accumulation of scale in hard water areas.

  • Hence they are mostly confined to cold climates.

The indirect type of heaters generally makes use of a heat exchanger that generally differentiates between the potable water and the heat transfer fluid.

On the whole, both direct and indirect solar roof heaters can be subdivided into two types such as active and passive solar heaters.  The passive mechanism rely on heat convection for the transfer of heat transfer fluid or potable water and it’s construction and maintenance costs less while, the active mechanism uses taps for the transfer of fluids and it’s maintenance is far higher.


Solar Roof Heater: Design And Safety Precautions With Regards To Solar Roof Heaters.


The Solar Roof Heaters are designed based on a few general characteristics such as, the general temperature of the locality and the amount of water required as output from the system, changes in temperature due to a switch over in seasons or due to the recurrent day-night cycle and also, due to the possibility of over heating or freezing.

The minimum requirements of the Solar Roof Heaters are judged during the winter, when the amount of temperature required to heat up the water is maximum and the output of the system is at it’s lowest.

The maximum output is measured by figuring out ways to avoid over heating or prevent wastage of money on components which are not an absolute necessity.

  • Overheating can be avoided by using the drainback system.

This is extremely efficient for, the pumps gets shut off when the system reaches a preset temperature. Appropriate freeze control mechanisms have to be undertaken to prevent damage to the system.

Solar Roof HeaterDrainback systems drain out the freezing transfer fluid when the pump stops it’s process and indirect systems use an antifreeze such as propylene glycol in the heat transfer fluid.

Most direct Solar Roof Heaters use a manual draining system while a few others use freeze tolerant collectors made of flexible polymers such as silicone rubber.

Thus, with so much advancements being made in the field of harnessing solar energy, it’s high time that people start to buck up and begin using it  to get better results when it comes to conserving energy.
