- Does the water need to be full to work? - Are hot and cold water in the same tank? If so, is the transfer of energy in the boundary between hot and cold water not too much as to affect the effectiveness of the tank? - Is water pressure entering the system maintained throughout the water heater pipelines? Amazing video sir, thank you for giving us this.
-Water need to be almost full in tank otherwise air trapping may happen. -Hot and cold water is in the same tank to recirculate water again and again to collector to achieve required temperature. If you saperate hot and cold water recirculation problem may occur. - There is not much variation in pressure throughout system, slite variation may present to maintain flow of water.
@@SampurnaEngg thank you sir for the explanation. I have a doubt. So if water is circulating again and again to collector to raise to desired temperature so what is the condition for hot water pumping out from tank ?

Does the system need to be circulated or vented…….will pressure get too high. I’m only looking to bring up water temps from lake water ( 10C ) in order for the water heater to not be using a lot of electricity. Just warm water for laundry……but the system may sit for a few days before being used. Does it need to be moved or vented ? Thank you !
why the cold water and hot water kept in the same tank, what if we use different tanks for cold and hot water so that our hot water will be hot for more time if unused because of the no heat transfer to cold water, why we don't do that?
Yes, we can make arrangement as you have mentioned. Actually there are various types of solar water heater. I have mentioned only one type, there may be different arrangements than this.

Very good explanation of the solar hot water system. Can anyone please tell me why my hot water is cold in the morning even when the hot water is not used in the evening on a sunny day.
Good explanation thanks.. I have a issue, when entering cold water every time when reducing the hot water from tank for applications then full tank will get cold because every time it filling with cold water. Or when releasing hot water to tank only it allows to enter cold water.
The total volume of the system is constant and filled with water. Whenever hot water is removed from the tank the same amount of cold water will enter the system/tank. When water is not removed, it circulate in the system continuously and water temperature increases continuously.
When we pour hot and cold water in bucket, velocity, inertia and momentum is high and hence it get mix with each other. In the tank of solar water heater the velocity of cold and hot water is very very less actually it is at micro level ( such kind of velocity can be observed in the water when we heat water in pot by using normal gas stoves). So because of micro level movement of water it doesn't get mix with each other. Hope you got it.
When hot water is poured in bucket with cold water , then it get mixed, but after some time, if u check temperature of bottom and upside ,it is different. But as hot water prefers to be upside when we put our finger we feel hot

Ok so water is heated because of sunlight and water moves from lower to higher region due to density difference & (without any external motor ) . Also hot water has less density and moves up, whereas cold water has more density and stays down.
No, There are safety measures included in system to avoid damage. If water temperature goes above certain temperature then circulation of water to solar panel is stopped and further heating is restricted.
Hello sir, Iam having a problem in the tank where hot water is stored, water heated from panel is not going up in the tank, as cold water going inside is filling full in the tank and over flowing from the pipe where hot water should go in. This has stopped hot water to go inside. pls help sir, will be glad to have reply back from you. Thank you.
if I close the intake of cold water in summertime and keep it unsued to avoid hot water formation. is it good for solar panels efficiency? only hot water for a long time in the water tank will form steam. is this steam dangerous for tank and pipes?
It is quite dengerous for system and human being near to system, bcoz if you close intake valve of cold water, there will not be circulation of Water. Temperature of water already available in the system will increase and it will form steam. If you maintain same situation for long period the steam temperature and pressure increases to high extend and may cause blast. To avoid blasts safety valves are used.
What if cold water is directly conncted to solar collector? Due to both cold and hot water in same tank . This will reduce heat in the night. Proper insilated water tank can store heat till next morning.
When using hot water inthe night time, the cold water will come inside the storage tank and both water will mixed together and it will decrease the hot, so how we can prevent this??
I didn't understood question correctly, you mean to say cold water from solar collector? You mentioned solar panel which is not present in the system. Please elaborate your question.
Water will not be heated in night time. Water is heated throughout day, will be stored in insulated tank & can be used in the morning for bathing. It will work in winter or rainy season but temperature of output water will be slightly less.

Solar water heater system can be used for cooking purpose where first water converted into steam and then this steam can be used for cooking purpose. Such Project in implemented in Shirdi Sai Baba temple where near about 10000 peoples food is cooked by such solar system. For more information just google Shirdi solar system for cooking.
This is the best explanation I have seen on youtube! Thank YOU!!!!

💀💀💀
will there be heat transfer between cold and hot water? as there is a direct contact in the tank
Thank you sir for helpfull explanation 🙏
are the hot water and cold water are physically separated in the tank?
well done, well explained

What if thehot water and cold water upper and lower pipes be seperated by a sun facing miiror to reflect all sunrays to bottom of upper pipe?
Does the cold water and hot water inside the tank will have any separater?
Yes, In some heaters saperator may be available. Actually there are various types of solar water heater. I have mentioned only one type, there may be different arrangements than this.

Sir, why can't we use two different tanks? One for hot water and one for cold water?
Actually we will pour hot and cold water in the bucket they will be mixed right .... why here in the tank doesn’t mixing hot and cold water?
When we pour hot and cold water in bucket, velocity, inertia and momentum is high and hence it get mix with each other.

Also hot water has less density and moves up, whereas cold water has more density and stays down.
Nice explanation sir

Thank you very much.. nice video.....I always face trouble to get solar hot water .....if you could help us by showing how the regulation knobs work
If we dont use hot water for some days.the temperature inside the tank will damages to tank?
No,
There are safety measures included in system to avoid damage.
If water temperature goes above certain temperature then circulation of water to solar panel is stopped and further heating is restricted.
@@SampurnaEngg which device or which thing is used for that purpose?
Temperature and pressure controlled valves.
@@SampurnaEngg thanks
Better way of teaching

can make different tank for hot water and cold?

@@SampurnaEngg thank you for clearing doubt.
@@SampurnaEngg so solar heater doesn't have over pressure valve / expansion valve?
@@SampurnaEngg nice info
my talnk exhausts the hat water always. what is the solution?
Use a bigger tank/ system maybe.
What if cold water is directly conncted to solar collector? Due to both cold and hot water in same tank . This will reduce heat in the night. Proper insilated water tank can store heat till next morning.
If you connect cold water to the collector, you can recirculate the water and hence we may not achieve the expected high temperature of the water.
Good information
Thanks 👍
for how long water will be hot in this system?
and after how much time water become hot?
It will be depends upon the size of water heater and type of insulator used.
When using hot water inthe night time, the cold water will come inside the storage tank and both water will mixed together and it will decrease the hot, so how we can prevent this??
Nice video ☺️
Thanks 😊
Nice
Thanks🙏
How to make this animation
Nice ❤️
Thanks 🙏
If the outside temperature falls to below zero, the water in the glass tubes will expand and crack the tubes!
In collecter why both hot and cold pipes are on same level
V good💯
Thanks a lot
Natural circulation solar water heater
What if cold connection done direct to solar pipes and tank is used only for hot water storage?
What if I want cold water
My biggest doubt has been cleared now
bro 🤝
what's that doubt bro?
@@kittukrishna5147 hot water flowing system
ok. Thanks for reply
So basically there are two types of solar panels one works on heat other works on light rays displacing neurons N and P
Why the cold water don't come straight from the tap to the solar collector?
I didn't understood question correctly, you mean to say cold water from solar collector? You mentioned solar panel which is not present in the system.
Please elaborate your question.
@@SampurnaEngg Forgive for that, Meant solar collector.
So that hot and cold water keep exchanging in water tank
I am doing a project on solar air heater. Can you tell me how to make animation for my project ?
This animation is done by using PPT,
You can use Fusion 360 or other available softwares.
Perhaps a small solar operated pump would improve efficiency?
❤
What if clouds block sun light, is there any backup system.
The water tank is insulated. So, the water inside is being kept warm.
If clouds block sun, water will get light warm due to diffused sun rays.
Diffused sun rays are reflected sun rays passing through clouds.
Super video.. One doubt is will this system works in night or winter or rainy seasons
Water will not be heated in night time. Water is heated throughout day, will be stored in insulated tank & can be used in the morning for bathing.
It will work in winter or rainy season but temperature of output water will be slightly less.

Ok
THERMO-SYPHON TECHNIQE
It's water tube boiler concept
Yes
don't understand why cold water should go inside the tank. Cold water should be directly connected to the solar pipes.
Maybe to settle down the sediment
I also comply the doubt
How it works at night time
Water gets heated in day time and stored into insulated tank. This water can be used in the morning. In night water doesn't get heated.
What will be temperature of Hot water
About 60 degrees.
Night time no sun Light how to hear water?
Water will not be heated in night time. Water is heated throughout day, will be stored in insulated tank & can be used in the morning for bathing.
Solar heater provide u 48hrs of hot water
There will be transfer of heat in tank
Hiiii
Hloooo
Vinod Habale TYME
What is solar?
I need a solar water heater for kitchen only, can u guide me any setup and cost
Solar means 'by the sun'. The water is heated by during the day by the sun's heat, that's why it's called a solar water heater.
2:45 to if what is that talking english
Dont say cold water. Its normal water . You are confusing me
