Reuse and recycling should be a objective to consider in our daily lives where We can also build utensils that really provide a added value on a day-to-day basis.
With imagination and a bit of crafts, all in our houses we can build a solar water heater or hot water tank and shower with hot water thanks to the solar thermal energy that the sun provides us, a great renewable energy that has no cost and that undoubtedly from our pocket to the environment will sincerely thank us.
First I would like to highlight what a solar water heater is and how it works:
The main parts of the solar water heaters that we will need for the construction of the water heater are:
You have to remember that, the panel where the water will be heated by the Sun, it can be built in different ways shapes. Normally colored tubes are used black – traps heat better and is easier to assemble – , plastic bottles (PET), soda cans, mattresses, tetrapack, vegetable boxes, pallets, among others.. But let's see everything more precisely…

The step-by-step construction of a water heater household first requires knowing some aspects basics, tools, etc. So we start with:
We leave the data of the material to be used and tools. Remember before buying anything, check if you have it for home.
The tools we probably need are the following: common in DIY Broadly speaking, we will need:
There are some considerations to be taken when locating the homemade water heater. We should consider on location:
With reference to orientation should be perpendicular to the Sun, for South America in North orientation, for Europe, in South. If ya want a tilt collector for the whole year, it is normally the angle of latitude of the place + 10.
For the assembly and assembly of a water heater installation, we should follow some guidelines:
As we can't put all the instructions so detailed in an article. First, we have compiled two excellent documents that guide us step by step, and a perfect video:
The following video is from INTA and they explain it very well…
Best of all, sustainable water heaters are built by reusing materials from material recycled as; Plastic bottles (PET), cans soda, mattresses, tetrapack, vegetable crates, pallets, among others.
Here, imagination plays an important role in the use of the materials with the main objective that we need some translucent containers to contain the water and other more resistant materials for the support of the packaging.
Here we can see an example of how it is heated the water so that you can bathe afterwards.
It is built in a few days and it is estimated that a family of 4 members, uses 80 liters of hot water per day in the kitchen and bathroom.
Usually the roof of the house is used as a support because once built, it is placed in the direction of the sun on the roof of the house and is charged approximately with about 100L of water (Obviously it depends on the size, but 100L is considered to be enough for a family with normal habits), the weight must be supported by the structure from the ceiling.
Companies collaborate with them and donate the materials they if it were not for this great project they would be thrown away (De interest see the circular economy article to understand how preserve raw materials).
In addition, they teach training courses and are encouraged in this way way renewable energy carrying out a social action where joint work and social mobility is palpable.
Here is another step by step guide on how to build a ecological solar water heater.
Fantastic! Right?
It can also be built by schools, in the clubs or neighborhood centers as a community task, or simply in the houses, as work and pastime of the whole family.
Not only will you save energy, but you will be helping to curbing climate change by reducing greenhouse gas emissions CO2 into the environment and raising awareness about recycling.
