This is great to see. I'm sure in some countries it gets hot enough that this system works well. I wouldn't use this system for our water in the house as we are not hot enough. The coils I would try to support the exsisting system. Thank you!

Wow 70 BUCKS i,m definatly going to try that ,, thanks

Thank you v much very nice presentation I like it , AZIZ From Bahrain

I shall take a day or two get back to U...this

time...  of year is DASHAIN...a week long festival in this part of the world.

vijaya...it is question of insulation...good insulated barrel would create no loss in heat for more than 24 hours.

Why does the black pipe need to be elevated? I have seen pipe put directly on metal laminate roofs. Would that work just as well, and do away with the need for insulation on the bottom?

Where are the diagrams on your blog? I can't find them and need them. I will have them translated into Spanish to use here in Guatemala. Thank you for posting this wonderful information! CatherineTodd2 at gmail dot com

Very good idea at very low cost, thank you for posting . Please mention How long hot water remain in the tank ? Also mention the temp of water in the morning after sunny day .

[debeshbhattarai]

This is in-fact spelling mistake, its should have been 70 USD ( Dollar), The cost of the entire installation in local currency converted into dollar while it was assembled in Kathmandu, Nepal. One USD that time was around 70 Nrs.

What are "dollors"

[callmeshane303]

I would have just laid the coils flat.

[descargaelbano]

@callmeshane303 The coils have to be in a cone shape for this system to work properly. The cold water enters the bottom center of the coils and rises through the spiral as it warms up acting like a "free" pump. The water continually circulates in the sun due to the rising hot water in the spiral of the coils.

[callmeshane303]

@descargaelbano

I call bullshit.

Study up on convection and density.

[descargaelbano]

@callmeshane303 Apparently you don't know what you are talking about. The hot water wants to rise in the pipe just like hot air goes up a chimney or fills a hot air balloon. "Flat pipes = no flow", "rising pipes = free water flow". The base of the coil needs to be lower than the bottom of the tank for this to work, just like in the diagram. Why don't you ask debeshbhattarai and see what he says too about your "pumpless" flat coils?

[debeshbhattarai]

@descargaelbano

There U are right, the spiral coils with mild elevation as in our illustrative diagram helps the buoyant hot water to rise to the hot water inlet of the storage tank. We have been using this innovative solar for several years here in Kathmandu. The normal solar gain is in winter is not less than 35c can shoot up to 45C.

One can always build one on his own to check the beauty of this simplest DIY innovation with the help of our numerous illustrative posting in YouTube.

@debeshbhattarai

You are also a dumb fuck - there are bacteria that grow in warm water, that go up inside the nose and infect the brain - causing mennangitis and death.

You must heat all of your water to above 60 - 65*C, to make it safe to use.

Fucking idiot.

@descargaelbano

I said - a flat panel is a lot easier to make, I did not say it has to be laid flat, nor for the plumbing to and from it, are to be set at the same height - thus stopping the principle of thermonic siphoning - you dumb fuck.

I also said a flat panel was a lot better from the principles of ease of manufacture and efficiency and mounting - compared to that piece of shit you have made - you dumb fuck.

[descargaelbano]

@callmeshane303 That's NOT what you said. You said "I would have just laid the coils flat". That was your only comment before mine. If the coils were laid flat then you would in theory ONLY have approximately 2.5M of rise in the diagram at 5:15, if the coils are cone shaped as in the diagram you will have rise(and water flow) in the entire length of the pipe(33M?) plus the 2.5M of rise which will steadily flow water by itself on a sunny day if you could see into the tank. It's a great design A+

@descargaelbano I really enjoy learning new techniques but find it so childish when I read people abusing other people. Rather than swearing at people (childish) how about posting your own youtube video with advice. People coming here are here to learn and are intelligent enough to research what works and doesn't work for themselves and their countries.

[Nene1192]

@Nene1192 Sorry this comment was meant to go under the two posts below!

[descargaelbano]

@Nene1192 I wasn't the person who posted the swearing posts. It was "callmeshane303". Please re-read the posts starting from the BEGINNING and you will see that I only replied with a comment on why debeshbhattarai has the black coils in a cone shape rather than flat. "callmeshane303" was the person who said I was a "dumbfuck" and debeshbhattarai was a "fucking idiot".

Excellent! Love the backround music as well! This video is so cool! Good job and thanx for spreading the info! Keep it up! Now I try!

[centervilletn]

thanks for posting this video..im working on my own solar water heater...maybe ill post a response i think i have some low cost improvements.
