@@Exteeeze basically, the energy being put into the water is being wasted by how long it takes to transfer. Its 500deg inside the grill - but that heat isn’t being transferred to the pool. It’s staying in the grill. Ideally - the highest sustainable temp inside the grill, whilst at the fastest flow rate to the pool thats possible, is whats desired. He’d be better with 250deg in the grill, and a 5x faster flow rate. You’ll heat the pool faster, and burn much less gas doing it.
Nice video filled with good tips & trix. I'm setting up a solar powered pool heater right now and my goal is 30°C / 86°F in the pool. I'm starting with 250 meters / 820 feet of 20 mm / ¾ inch PEM hose in a flat rooftop setup. A 20V rainwater barrel pump (2,000 liters - 528 gallons / hour) will be connected directly to a solar panel, so it's a completely automatic system controlled and powered by the sun. No sun = no pump = no heating. Since I'm located at 60° latitude in the northern hemisphere, I'll guess it'll be some problems and math to solve along the way, but it'll be fun. Keep up your good work
The unit heats up fast and is super quiet. It looks fancy czcams.com/users/postUgkxl8Od2BvnGbn1ffwqsuFXW0QnmcZgMiVY and can be kept in the living room. It gets hot within a split second of turning on the unit. The build quality is exceptionally good and is safe to be around kids and pets. This one is super quiet and can be kept on while in office meetings, my wife loved it. It shows the temperature right on the unit which is very useful and adding a rotating feature helps to heat up the surrounding, so other people will not fight with you for heat. It is right as described in the description..!! Definitely recommend!!
I’m wondering if the system would be more efficient if the only suction was from the pool and then the solar heated water is discharged to the inlet of the grill. Also, consider using a much shorter hose between the pool and the grill, so you’re not losing heat to the air You might also consider putting a large cookie tray above your copper pipe to trap more heat and make the copper heat. Transfer more efficient.
just an idea since you are mechanically inclined -- a more efficient way of heating your pool and also a great way to cut down on your house utility bill would be to run your hose to your a/c unit outside house and transfer the heat to the pool. i've seen a pool that was heated by basically being a big heat pump for the a/c unit.
That works, and if you are a bit more mechanically inclined, you can use the pool water to cool the condenser coils on the AC unit. This will warm the water and at the same time cool the Freon in the condenser. That will not only heat your pool water, but save electricity as well by increasing the efficiency of the condenser unit. The compressor in the AC condenser unit doesn’t have to work as hard to liquify the Freon, and uses less power.
As others have said, you want the fastest flow possible. You need to move the heat to the pool as fast as possible, and it will be easier on your pump as well
This is flawed on so many levels. 1) The flow going through the copper piping should be maximum rate possible. You dont slow it down to increase the heat of the output, all you are doing is restricting the efficiency of the heat transfer to the water. You are also putting more pressure on the pump shoterning its life. 2) Putting that hose in the outlet with the tap puts more pressure on your pump reducing its life and again doesnt make sense from a physics perspective in terms of transferring the heat to the pool. Also you are ruining the circulation of the pool water which is vital for the health of the pool. - In summary you should piss off the outlet hose idea, and speed up the water through the BBQ. Must cost a bomb to heat your pool with a BBQ tho.
The ideal thing would be to transfer boiling hot water through a tube and into your pool at the flow rate of a garden hose on at full blast. I just haven’t the slightest idea how to achieve this. Using 300 feet of black irrigation tubing with a pump designed for draining a pool cover was ineffective. After the initial blast of hot water, the water traveling through the tubing would quickly cool.
I wouldn't imagine that to be the case. Many residential homes nowadays still have a ton of copper water lines and drain lines in their home. It was a standard practice to use copper for that back in the day
So how are you pumping the water through. I have an extra pump but it issues the big pool hoses. I have a small utility pump that uses garden hoses but I don’t think it can be run for hours on end. Thanks for you awesome video. I really need a cheap way to get the temp up by like 6 or 7 degrees.
I put the hose into the return. This way you do not need a pump. The hose only takes up a small part of the return coming back to the pool. Put the hose in the return with the filter off because the pressure from the return will just push the hose out. I use a few tie straps on the hose. Leave the tie straps long so that it will catch the inside of the black ribbed (return tube). This will hold it in place. I will make a video showing this step. It is really easy.
Wanted to run black plastic tubing several times around the top rim of my 18 ft round pool, held in place with short bungee cords. Boss wouldn't let me. LOL
I just bought a house in Florida with an above ground pool, of which i know absolutely nothing about. I wish i had 1/2 the knowledge of the people commenting on here. I would at least know where to start. 😊
I only use 1 tank. I turn it on high for about 8hrs. I use the grill/propane to raise the temp 5-6 degrees. Just enough to take the chill out of the water.
To greatly improve this, you should not use a continuous coil. You really want to use a manifold for the entrance and exit with parallel small diameter tubes connecting the manifolds. This way every tube starts with water at the current pool temp... thus the greatest heat transfer rate. Also you can't consider temp only for optimizing. The mass flow rate of water times the temp rise is the true measure of energy being transferred.
I usually run it for at least 6-8hrs. Example: 7a-2p. My pool holds around 18,000 gallons of water... If you have a smaller pool it will heat up much faster.
Restricting flow reduces overall heat transfer. Push as much water as practical through the tubing to heat the pool faster.
Huh

You're basically trying to cool the tube instead of heating the water

Yep, if you have a geothermal unit you can do the same and that's basically what the pond helps with anyway.
Turn the flow up!! Its better to get 10 gallons a minute at 10 degree increase than to get 5 gallons a minute 17 degrees increase.

Can you share the link to the grill heater's submersible pump?
Do you also eat off of this grill or is it just dedicated to heating your pool?

Lol, I love America. We have the most ingenious people.
Thanks, bro
I want to ask when water pass through cu hot tube is there any dangerous material come from hot 🔥 tube in water
?
Thanks

could you give me links of the items I would need to do this please

No, he means the electric pump you are using with the copper pipe and grill.......
Hi can I use part of your video to my compilation homemade inventions ?
Yes
@@miketomasetti Thank You

Come set mine up 😊
what size copper tubing did u use
1/2inch
just heat it with your gas grill the way that other dude did...i found that so funny
Interesting. How long will a tank of propane last ie., for a typical day of “pool time,” how many propane (tanks) do you go through?
I only use 1 tank. I turn it on high for about 8hrs. I use the grill/propane to raise the temp 5-6 degrees. Just enough to take the chill out of the water.
what is the diameter of the coper tube/pipe?
1/2in copper tubing
To greatly improve this, you should not use a continuous coil. You really want to use a manifold for the entrance and exit with parallel small diameter tubes connecting the manifolds. This way every tube starts with water at the current pool temp... thus the greatest heat transfer rate.
Also you can't consider temp only for optimizing. The mass flow rate of water times the temp rise is the true measure of energy being transferred.
That will amount to hundreds of dollars in propane. Are you kidding?
How long do you run the grill heater?
I usually run it for at least 6-8hrs. Example: 7a-2p. My pool holds around 18,000 gallons of water... If you have a smaller pool it will heat up much faster.
@@miketomasetti how much gas does that burn? Any idea in kg?
I use propane. I tried charcoal and wood but I couldn't get it hot enough. I also could not get it to stay at a high temperature.
Interesting
Don’t reduce the flow! You are reducing efficiency!
“Slow down the flow” …… whatcha thinking ? Heat is heat
I just pee in mine although it's only warm for a second
If the water been pumped back into pool is 95 degrees why hasn't it burned your fingers ?
Isn't normal hot showers over 100 degrees
degree Fahrenheit
Your body temp is about 98 degrees so 95 can't burn you
Lmao delete your comment please. Lord have mercy
😂😂😂😂 got yous all thinking didnt it
