" 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+"

I think the rise must be important. CT

Portable Solar Water Heater DIY a Green Gold

I never thought I shall bump into this. This miniature DIY solar water heater is the Green Gold, but innovation for simplicity should never end. You must try it at home and reinvent the energy bills to protect the GREEN and mother earth.

This DIY solar water is made with very basic materials one gets everywhere. Here we have used a simple container used for carrying goods at construction site as a main heat absorbing element along with few more items like, a roll of clear level pipe, a small plastic jar/bucket of around five liter and Styrofoam ice box for insulated container.

I am sure green enthusiast shall take this DIY across the globe and help reduce deforestation and conserve the precious resource for future generations too... We do need to care NATURE a LOT MORE DO NOT YOU THINK SO.. !!! ???

20-gallon Solar Heated Hot Water Heater and Shower

20 gallon Solar Heated Hot Water Heater and Shower

Build this solar heated hot water shower for as little as $25 (if you have some spare lumber and items laying around) and save on hot water heat costs! This 20 gallon capacity shower provides enough water for a family of 4-6 to take daily showers and the design is simple. The plastic cover over the top enhances the solar heating, making this a shower that can possibly be used 6 months out of the year in even the colder northern climates. You only need the south side of a garage, house, or shed to mount the frame. The shower fills with an ordinary garden hose.

This shower works great! Tell your friends about this idea - we need to do whatever we can in these times of +4$/gallon oil and gas prices!

Check Out the NEW IMPROVED version of this solar shower!

New Improved 20-gallon Solar Shower! - Free Building Plans: 

http://www.savehouseholdenergy.com/solarshower-new.html 

This new improved solar shower features an exterior of recycled slab wood (scraps from a lumber mill that are normally discarded), a glass top on a weather stripped frame that flips open and seals in heat much better, a door that opens and closes securely, and a light that illuminates the shower after dark. So now I can take a shower in the morning and the water is still luke warm (hot summer weather). Also, now no tools are needed to replace the bags just flip open and secure the top with the rope pulley system. All-in-all these were some nice changes that I think will greatly increase the use-ability. The steps I used to build this shower are given below.

Build a simple solar water heater

 Reposted from I Will Try.org - great name!
http://www.iwilltry.org/b/projects/build-a-simple-solar-water-heater/

Introduction

I’ve seen a few different designs for solar water heaters and I wanted to share my own. It is quite an efficient design since every square inch of collector surface is in direct thermal contact with the water being heated. You can easily modify the design to any size you like. I made mine 8ft long by 22″ wide so that it can fit between the rafters in my attic. Tests showed that system output averaged about 530 Watts, heating 20 litres of water from 24 degrees C (75 degrees F) to 47 degrees C (117 degrees F) in one hour.

Aside: I’m in the middle of re-roofing my house and plan to build in a transparent section of roof in one area. Then I can experiment with different solar collector designs like this one and install and remove them easily from inside my attic instead of having to go out on my roof. It will make the plumbing easier too. The drawback is that if a collector springs a leak, it will leak into my home instead of into my gutter. See Build a solar attic for details.

Warning – Don’t drink the water

It is not my intent for this design to be used for heating drinking water. The plastics and glues used will leach into the water so it’s a bad idea to drink any water that has been inside the panel. If you want to use this design for heating drinking water you should make a heat exchanger. Run the water from the collector through a coil of copper pipe placed in a tank suitable for drinking water. This collector design is also not meant to withstand city water pressure, but if you use a heat exchanger and an appropriate tank (such as a commercial hot water tank) you can use a collector like this to heat drinking water at city water pressure.

Concept

The collector is made from Coroplast (see http://www.coroplast.com) which is a corrugated plastic sheet, commonly used for making signs. It has multiple square channels running lengthwise from end to end. When I first saw this type of sheet I immediately thought, “Wow, this would make an excellent flat panel solar collector if only there was a way to pipe water through all those little channels.” Several weeks later, a method of doing so occurred to me. If a slot of the right width is cut lengthwise in some ABS pipe (so the cross section looks like a “C”) then this pipe can be fit over the end of the corrugated plastic.

The seams can be sealed to make everything water tight. The sheet can be painted black and voila… you have a flat panel solar collector.Because the whole collector is made of plastic, it is important that the temperature doesn’t get too high or it will soften and possibly spring a leak. 80 degrees C (176 degrees F) is about the limit. Don’t think it can get that hot? Think again. In practice the maximum temperature is difficult to guarantee.

Water may stop circulating, or may drain out completely for a number of reasons and the panel will overheat. Therefore this may not be a practical design for residential installation but it is an inexpensive, easily built experimental system that produces as much or more hot water than commercially available systems. Mine cost about $60 in materials (about $4.00 per square foot) and about 6 hours of construction time.

Re: Solar Pool Heater

robert brooks to me

Sept. 22, 2011

Robert, I'm here in Guatemala and looking at how to best heat the small swimming pool at my friend Georgina's small hotel. We are on a very tight budget so I need to use inexpensive or recycled materials. Can we heat the pool with "all pipe" without a pump?

I've seen a coil of black 1/2 inch pipe on a roof that makes a hot shower. We can put pipe on the flat roof of the hotel restaurant and pipe it down to the pool, or put those plastic liter bottles since that apparently doesn't need a pump.

I know nothing about plumbing or electronics, so any help is appreciated. I have your list below. You said "just use pipe," and another architect friend who is emailing me said the same thing. ???

We are measuring the pool and thanks for the vol. sq. in. formula below. I didn't know it. I'm uploading photos of the hotel on flickr. Very slow going (slow internet connection here) but they should all be uploaded by tomorrow. Some are there already.

Dear Catherine,

All that need done is; the outlet of the pool filter gets diverted to a line of black pipe ( or green hose or any sort of hose)

The end of that line gets redirected into the bottom of the pool. Naturally, the more lengthy the journey through the pipes becomes the warmer the water becomes.

If the pool doesn't use a pump for it's filtering; any sort of pump that handles water will do. Additionally, solar covers work to retain the heat in the pool.

There are many good videos on you tube describing the process. I hope this helps.

Building a PVC pipe solar hot water heater can reduce or eliminate the need to use "grid" power to heat water for the home. By using PVC pipe encased in a heat-building box, then installing this box in a location that receives ample sunlight, the water is heated and pumped into the home using thermal energy. Installing several of these heat boxes will provide an abundance of hot water, and can be built and installed by an average backyard engineer in about three hours.
