PV Gap

i am thinking to buy solar water heater for my home ?

We Answered:

There are many considerations. First what you are not asking about. There are solar photovoltaic panels that produce electricity. The website that Kool referenced are photovoltaic panels. Then there are solar thermal panels that are used for solar space heating and solar hot water heating.

Then there are three general styles of solar water heating panels. There are batch heaters that have the storage as part of the panels. They are cheaper and often with few moving parts but are better used where there is no chance of freezing.

Where freezing is more likely there are pump down systems that eliminate water in the system when it might be likely to freeze and...

Then there are systems that use a heat exchanger and separate water with anti freeze in it from the hot water that it heats up and stores.

For all of these styles of systems there are solar collectors that are some variation on tubes in a box and the newer, more expensive, hi tech vacuum tube collectors. The vacuum tube collectors collect more heat on cloudy days and can get much hotter. Sometimes one vacuum tube collector is used at the end of conventional collectors or they might be used for commercial systems like a laundrymat.

You should generally be looking for a "pay back" period of between 3 to 5 years on a solar collector water heating system. How many collectors you install, what type of system you install will depend upon how much hot water you want to produce (80% of your needs is usually economical while 100% might require somewhere to dump excess heat of some days to keep collectors from overheating... like a loop in the cold earth.), what the climate is like where you live, and how much you are willing to spend initially.

How do I make a home made solar heater out of piping for my pool ?

We Answered:

Make a long run of metal pipe where the sun will hit it. Have a bunch of switchbacks and put a metal plate behind it to reflect more heat back to the pipes.

Solar Water Heater - What is the Expected Lifespan of a Home Solar Water Heater?

We Answered:

Home solar water heaters have a lifespan of 15-20 years. They also deliver more amount of water at higher temperature than regular water heaters because they can heat up to 80 gallons more water.

You can also use a solar heater along with your regular heater and increase the lifespan of both units.

ok friends i want to make a solar stove and solar water heater in home pls help me?

We Answered:

I just typed the words "build solar oven" into a search engine and got many many hits. One link is provided below.

Likewise, I typed the words "build solar water heater" into a search engine and got hits. A link is provided below.

I'm not sure that these are the best plans; they are just the first that came up that actually looked like instructions on how to build a solar system

I'd suggest that you do a bit of work yourself with a search engine until you find exactly what you are looking for.

Good luck!

I want Solar water heater for my home. we are 4 member family advice me what litre & which make is best?

We Answered:

solar hot water is generated from the heat of the sun (solar electricity is generated from light). you would need to make sure that you had an alternative way to heat the water in the less sunny times. if you have a fuel stove (gas, oil or wood for example) it is possible to have the water plumbed through the stove to use that heat to boost the water temperature when needed. I lived for a while with solar electricity and solar hot water channeled through the wood stove, but if you have to have electric boosters it can become quite expensive and usually the solar heaters are more expensive than other options. I dont know what makes and model you have available there, but make sure that the release valves are readily available because they fail every five to ten years and you will need to replace it.
