automated solar hot water power shower using black plastic pipes
The black ABS 50mm pipe filled with water is arranged in the blue fish bone pattern on the roof to get heat from the sun for a warm shower.
The features of this design are as follows: the pipes are installed on the roof facing the southwest, at an altitude of about 30 degrees, and provide an electric pump of 350 watts for the appropriate \"power\" shower.
Heating water is a great way to use solar energy, water needs a lot of energy to make it hotter, we all need a shower over and over again, right?
If this system takes 2 hours of warm-up time from 15 °C to 35 °C, then the power is 350 Watts because it contains 30 liters of water.
The main secret behind this design is the use of waste water pipes and fittings to allow the pipes to extend down to the central spine at 2 degrees.
The whole system needs self-draining so that every drop of water enters the pump at a good flow rate, thus fully supplying the pump.
It may be tempting to absorb more heat from the sun with a smaller diameter tube, but this may cause the pump inlet to be restricted and the pump output pressure to be significantly reduced, it will not be a proper \"power\" shower.
Also, unless a long length is used, a smaller diameter pipe will mean less water, which will make self-draining very tricky.
Self-draining is crucial because we don\'t want to introduce cold water into the system before people take a shower
Nothing is worse than a warm shower that suddenly gets cold!
Also, the shower must be completely free of water in the winter, otherwise the frost will damage the pipe.
The black plastic pipe is \"open\" and there are three 2 \"vents on top of the pipe that are equally spaced and covered with fine mesh to prevent the leaves from entering.
This means that unless the temperature reaches the boiling point of the water, no pressure will ever accumulate in the pipe.
Although the place I live is good, if the system is installed in a hot country, it needs an exhaust valve to pour water, for example, 80 degrees Celsius, if the temperature rises.
The system is fully automated, which means that the pipes are automatically filled with fresh water after the \"dirty\" shower.
When the automatic solenoid valve is turned on, fresh water comes in, it goes up into the 38mm black pipe from very close to the pump inlet, and up into the central ridge bottom array of the 50mm pipe.
It then spreads freely to the left and right, and it fills all the pipes at the same time due to the large, not restrictive, internal cross-sectional area of the pipe.
Eventually, the float switch at the top detects that the water has reached the top of the pipeline array and the solenoid valve is off.
When the pump is turned on, it draws the warm water back in the exact opposite way, and the water freely goes down through all the pipes into the bottom of the central spine.
There is no limit to flow in either direction, except for a small amount of pressure due to gravity, there is no negative pressure or positive pressure build-up.

Most of the accessories are obtained from a company called BES in the UK.
Cut 50mm tubes into the following :. .
And lay on the box section on the ground and assemble without cement to check if all the parts are assembled together.
Note that most accessories are 92 degrees instead of 90 degrees as they are designed to produce 2 degrees to a level of wastewater discharge, which is very in line with our requirements.
In addition, the box profile sheet is used upside down as this provides more planes to attach plastic clips to clamp the structure.
All \"horizontal\" pipes are inserted slightly down into the central spine at 2 degrees.
Remove all the pipes and reassemble the central spine, be careful to keep all the other pipes as close to their original position as possible to prevent them from being confused with each other.
Some of the accessories I use are a bit loose and need extra cement to stick them together.
Before bonding, the surface needs to be cleaned and polished in order to obtain a rough finish before being generously coated with cement, pressed together and producing a 90 degree twist.
The tin says 10 minutes to heal but I find this is not true and it takes at least an hour for the joints to solidify at 15 degrees C before doing the next batch of pipes.
While these four parts are not really horizontal, at a later stage they will install inspection caps to place the level sensor.
I place the caps vertically because it makes it easier for them to arrive in the future.
It is important to assemble in the right order so that the final part can be slotted and glued together without too much difficulty.
A small part of the pipe in the photo will be the last piece of glue.
After a few hours, there is rest between each major stage, and the whole structure can be arranged on upside down steel plates.
Its position is very careful so that all \"horizontal\" pipes are 2 degrees in the horizontal direction and all vertical pipes die in the vertical direction.
The last series of pipes formed a very clever and neat blue fish bone pattern, with most of the drainage flowing to the central spine and bottom, just in the best position to deliver the pump for the power shower.
It\'s time to test the shower and check the leeks.
Make a temporary attachment on the pump, fill the whole structure with water, and look for drops and drops.
If the sun is shining, the water will warm after about 2 hours.
Some pipe cement and hemp rope can fix the leakage.
With the correct position of the pipeline array on the paper, self-tapping screws can be used to screw into the fixture.
Several cordless electric drills are very convenient for this work, one for drilling and the other for screwing in.
Now all the clips are unscrewed again, everything is removed and the sheets are brushed off.
It is then coated with aluminum reflective paint to get a little extra sunlight by reflecting on the black pipe.
It is important to constantly stir paint cans during painting.
First, screw the steel roof plate on the roof with self-drill and self-sealing screws specially designed for this purpose.
In order to get the best drainage to enter the central spine, the sheets must be fully horizontal.
Then twist the pipe back to the sheet.
The main outlet of the pipeline array has a reducer installed at 32mm and then forms the starting point of the feeding line of the pump.
The first accessorythe white one -
It is a standard 90 ° compression bending.
Note how it operates on the drain clip, leaving enough space for the drain that is not yet in place.
The third photo shows how the 30 ° roof slope breaks down into true vertical.
Use a special fitting, as shown in the last photo above, called \"universal joint bending\", a compression fitting that can be positioned at any angle of 90 to 180 °very useful!
The trunk water enters from the blue pipe, bends through 90 °, passes through the 1/2 BSP solenoid valve, and enters the reducer from 1 to 1/2 through the 1/2 isolation valve, forming a \"male and female bend, into 1 \"\" T \"to install and enter the inlet of the pump through the 1\" barrel nipple.
Black fittings through the walls lead to an array of pipes on the roof for warm water.
The outlet of the pump is vertical up, there is a reducer of 1 \"to 3/4\" and enters the garden hose through a 3/4 \"barrel nipple.
The garden hose is equipped with a manual spray gun for the actual shower head.
Part: Please note that this special system uses AC 240v power supply and it can kill due to electric shock.
All connections must be fixed with strain-free eye-catching, and the case must be labeled \"impact hazard\" and prevent tampering with the appropriate lock.
All cables must be armored or with proper sheaths.
In order to comply with the law in many countries, this installation requires the signature of a qualified electrician.
A safer way to do this is to use the valve pump and solenoid valve.
How it works: there are two sensors in the system, one telling us if the pipe is full and the other telling us if the water in the pipe is hot enough.
Temperature is not part of automation, but it is very useful to know how warm the water will be.
As shown in the figure, the level switch is screwed into the top-level inspection cap and connected to the control panel through the junction box, which activates the solenoid valve or pump, depending on the state of the entire system.
The mesh on the breathing tube is to prevent the leaves from entering the water.
The Nano is programmed with six sets of main logic that handle all possible combinations of liquid level switches, panel switches, pumps and solenoid valves.
In some cases, we need to prevent the solenoid valve from opening even if the level switch indicates water shortage.
Also, we need to be able to turn the pump off and turn the pump on using the main panel switch.
As a safety function, the pump cannot be opened if the pipe temperature is too high, thus preventing scolding.
The Nano uses quite a few digital pins to run the LCD: in addition to that, the code is basically divided into six logical statements to handle the following: we don\'t just take a shower outside in swimming shorts, instead, a \"pop-up\" shower tent was set up.
The system worked really well on a sunny day and we took a hot shower for about 5 minutes until the water ran out.
In order to operate the shower, the red button on the control panel is pressed and held for a second.
There is enough time to get into the shower tent and the system will automatically detect when the dirty people will start taking a shower and provide them with some extra time to finish.
To stop the shower, press the red button again or we can wait for the countdown to finish.
The solar shower works fine where I live, but in a cold climate, some insulated boxes with transparent sheets on top improve performance.
In the hot climate, there are some shadows with nets.
May need.
If the temperature drops to near freezing point or rises to near boiling, the dump valve will be a very good addition.
This will be easy to add to the system as it is just a second solenoid valve that allows water to be released from the pipe.
If I am missing something in the comments section, please let me know and the instructions will be updated accordingly.
Value your comments!

Most of the accessories are obtained from a company called BES in the UK.
Cut 50mm tubes into the following :. .
And lay on the box section on the ground and assemble without cement to check if all the parts are assembled together.
Note that most accessories are 92 degrees instead of 90 degrees as they are designed to produce 2 degrees to a level of wastewater discharge, which is very in line with our requirements.
In addition, the box profile sheet is used upside down as this provides more planes to attach plastic clips to clamp the structure.
All \"horizontal\" pipes are inserted slightly down into the central spine at 2 degrees.
Remove all the pipes and reassemble the central spine, be careful to keep all the other pipes as close to their original position as possible to prevent them from being confused with each other.
Some of the accessories I use are a bit loose and need extra cement to stick them together.
Before bonding, the surface needs to be cleaned and polished in order to obtain a rough finish before being generously coated with cement, pressed together and producing a 90 degree twist.
The tin says 10 minutes to heal but I find this is not true and it takes at least an hour for the joints to solidify at 15 degrees C before doing the next batch of pipes.
While these four parts are not really horizontal, at a later stage they will install inspection caps to place the level sensor.
I place the caps vertically because it makes it easier for them to arrive in the future.
It is important to assemble in the right order so that the final part can be slotted and glued together without too much difficulty.
A small part of the pipe in the photo will be the last piece of glue.
After a few hours, there is rest between each major stage, and the whole structure can be arranged on upside down steel plates.
Its position is very careful so that all \"horizontal\" pipes are 2 degrees in the horizontal direction and all vertical pipes die in the vertical direction.
The last series of pipes formed a very clever and neat blue fish bone pattern, with most of the drainage flowing to the central spine and bottom, just in the best position to deliver the pump for the power shower.
It\'s time to test the shower and check the leeks.
Make a temporary attachment on the pump, fill the whole structure with water, and look for drops and drops.
If the sun is shining, the water will warm after about 2 hours.
Some pipe cement and hemp rope can fix the leakage.
With the correct position of the pipeline array on the paper, self-tapping screws can be used to screw into the fixture.
Several cordless electric drills are very convenient for this work, one for drilling and the other for screwing in.
Now all the clips are unscrewed again, everything is removed and the sheets are brushed off.
It is then coated with aluminum reflective paint to get a little extra sunlight by reflecting on the black pipe.
It is important to constantly stir paint cans during painting.
First, screw the steel roof plate on the roof with self-drill and self-sealing screws specially designed for this purpose.
In order to get the best drainage to enter the central spine, the sheets must be fully horizontal.
Then twist the pipe back to the sheet.
The main outlet of the pipeline array has a reducer installed at 32mm and then forms the starting point of the feeding line of the pump.
The first accessorythe white one -
It is a standard 90 ° compression bending.
Note how it operates on the drain clip, leaving enough space for the drain that is not yet in place.
The third photo shows how the 30 ° roof slope breaks down into true vertical.
Use a special fitting, as shown in the last photo above, called \"universal joint bending\", a compression fitting that can be positioned at any angle of 90 to 180 °very useful!
The trunk water enters from the blue pipe, bends through 90 °, passes through the 1/2 BSP solenoid valve, and enters the reducer from 1 to 1/2 through the 1/2 isolation valve, forming a \"male and female bend, into 1 \"\" T \"to install and enter the inlet of the pump through the 1\" barrel nipple.
Black fittings through the walls lead to an array of pipes on the roof for warm water.
The outlet of the pump is vertical up, there is a reducer of 1 \"to 3/4\" and enters the garden hose through a 3/4 \"barrel nipple.
The garden hose is equipped with a manual spray gun for the actual shower head.
Part: Please note that this special system uses AC 240v power supply and it can kill due to electric shock.
All connections must be fixed with strain-free eye-catching, and the case must be labeled \"impact hazard\" and prevent tampering with the appropriate lock.
All cables must be armored or with proper sheaths.
In order to comply with the law in many countries, this installation requires the signature of a qualified electrician.
A safer way to do this is to use the valve pump and solenoid valve.
How it works: there are two sensors in the system, one telling us if the pipe is full and the other telling us if the water in the pipe is hot enough.
Temperature is not part of automation, but it is very useful to know how warm the water will be.
As shown in the figure, the level switch is screwed into the top-level inspection cap and connected to the control panel through the junction box, which activates the solenoid valve or pump, depending on the state of the entire system.
The mesh on the breathing tube is to prevent the leaves from entering the water.
The Nano is programmed with six sets of main logic that handle all possible combinations of liquid level switches, panel switches, pumps and solenoid valves.
In some cases, we need to prevent the solenoid valve from opening even if the level switch indicates water shortage.
Also, we need to be able to turn the pump off and turn the pump on using the main panel switch.
As a safety function, the pump cannot be opened if the pipe temperature is too high, thus preventing scolding.
The Nano uses quite a few digital pins to run the LCD: in addition to that, the code is basically divided into six logical statements to handle the following: we don\'t just take a shower outside in swimming shorts, instead, a \"pop-up\" shower tent was set up.
The system worked really well on a sunny day and we took a hot shower for about 5 minutes until the water ran out.
In order to operate the shower, the red button on the control panel is pressed and held for a second.
There is enough time to get into the shower tent and the system will automatically detect when the dirty people will start taking a shower and provide them with some extra time to finish.
To stop the shower, press the red button again or we can wait for the countdown to finish.
The solar shower works fine where I live, but in a cold climate, some insulated boxes with transparent sheets on top improve performance.
In the hot climate, there are some shadows with nets.
May need.
If the temperature drops to near freezing point or rises to near boiling, the dump valve will be a very good addition.
This will be easy to add to the system as it is just a second solenoid valve that allows water to be released from the pipe.
