A Complete Installation Process of a DIY Solar Water Heater
Building a solar water heater is lengthy and requires lots of time and effort, but the good news is that it is not difficult at all. You need to follow certain instructions and the right set of tools to perform this DIY job perfectly.
You can use this warm water for multiple purposes; it will give you the luxury to fill your outdoor pull, hot tub, or any other traditional showering system at any time.
Now, let’s come to the actual instructions! You will find a variety of DIY solar water heater types in these guidelines. It’s up to you which way you will go or which type of solar heater will fulfill your requirements.
In order to perform this DIY project perfectly, you must follow the given instructions in the right sequence, and finally, you will surely get your desired results:
1. Getting Started
Initially, you must prepare for the installation process of any solar water heater or any other format for your home. Make sure all the tool kits and supplies are placed near you for easy access.
Moreover, wear all the protective gear before the start of this DIY project for your safety.
2. Cut the Wood
Now, bring the table saw to start cutting the wood. For accurate cutting, you must take all the measurements and mark them on your plywood.
Make sure you are cutting a single piece at a time according to your desired size, and straighten all the sides of your plywood with this table saw. It will help you to glue all these wooden planks smoothly.
While cutting the legs of your wooden frame, you must measure the height of a leg to build a perfect frame to fix the solar heater for your home.
3. Build the Top Frame
Start building the top wooden frame for your solar water heater tanks. This top plywood is necessary before creating the walls or sides. It is better to lay the wooden planks on any flat surface and glue all the frames on their edges to connect them.
You can align them with a speed square, and clamps help them hold their position. You should also drill holes and join these wooden sheets with screw pieces. This will fix all the plywood frames firmly with each other.
4. Build the Bottom Frame
To create bottom frame boards, you must drill pocket holes and embed them with the top frame. Again, apply both the glue and screw techniques to these pieces.
For more perfection, you should focus on positioning these frames with their holes so that they will properly be aligned with each other.
5. The Painting Session
Congratulations! You have successfully built a frame. Now, you should paint this wooden frame for a better finish. Start painting from the top of the frame, and if any material is left, paint the edges of this bottom frame, but first, complete the other three sides of this frame.
If you feel necessary, you can give a second coat to this frame after drying the previous paint on it.
6. Get Reading this Frame for Tubing
Mark the center of this wooden frame with measuring tape and drill the holes in this plywood. You have to create at least two holes for each zip tie. One will hold the input, and another will trap the output line.
For instance, if you want to add six zip ties, you must drill twelve holes at the center. It is better to thread these zip ties through the holes for firm support.
7. Installing the Tubing
Further, you need to install the tubing. To coil the tubing, make sure the tubes are not in tangle format. You can take assistance from any other person for this phase. If you require more zip tie holes, you can drill some more.
Set all the tubing coiled in your wooden frame, and if you find any extra zip ties, you can cut them off with scissors. Your tubing frame is ready now.
8. Attaching the Legs
Now, you have to search for the center of the wooden board to attach the legs. You can use the spacer to find this center spot. Now, drill the holes precisely to these spots to attach the legs.
If you need to attach the base frame for these legs to avoid any wobbling issues, then you can add smaller frames on each side for an accurate height of this wooden frame.
If any paint material is left, you should paint these four legs for a perfect finish.
9. Add the Acrylic Top
Finally, you should place the acrylic sheet on top of this frame and fix them with plastic drill bits. Make the holes in the acrylic sheet and re-drill the holes in the wood.
Now remove this sheet and clean the entire tubing area from its inside part. Place the acrylic sheet and add deck screws in all the holes. Now, start fixing them with a screwdriver securely.
You will see the protective film on this acrylic sheet, remove this film from the sheets from one side and finish it off by removing the entire protective film. You will see a shiny finish on this acrylic sheet.
To finish things off, join the hose connectors for the in-flow and out-flow of the solar panel heater. You have done it!
