Resistance heating elements are beauties in simplicity and low cost. They create however a lot of  problems, due to water residue minerals attracted to the surface, and the internal temperature os such element is very high and once the mineral deposit on the external wall is built this temperature even rise and is the reason of malfunction.


Now , induction heaters can solve much of those problems.

Ok Tnx for all math and reply... Today I hope I will take the water out of the copper box to see how much exacly oil does it contain and then I could then conclude exacly how efficient this heater is and then try to make more efficiency :)

This project cost me a lot to research it and do it on my own and the thing was there are people on the youtube that are showing this kind of heaters, but no one showed exacly how can it be done with all math on efficiency etc.

I saw one patent on it on air heater and there is one german guy who is searching for investitors, but no one who gave everything to the public and then we all could profit and help each other to make it even better, so that is what I want to achieve to share and to help each other to build more efficiency.

Im not saying that this path could lead to nothing then research that we couldnt achieve nothing more then 67% of efficiency, but then other people dont have to go so far as I did with financiel costs :)

So one more question that could help me on this trip:
Do you have any tip on how to inprove efficiency of this kind of heating system or any research already done on this?

I saw electrical existence heater and yes they are saying 98%, and I also build the friction heater and didnt go much ferder on it, but I miss that guy on youtube oliepigg username he just dissappierd with his friction heater :(

The mineralization issue occurs in water heaters with an insufficient sacrificial anode.  We are talking about an oil heater.  Mineralization is not an issue. 

The internal temperature of a resistive heater element can be whatever one chooses from just above room temperature to well over 1000C.  Hotter transfers more thermal energy for a given size heating element.

Induction doesn't solve a problem that doesn't exist: mineralization in an oil heater, or higher working temperature than is desired in the heating elements.

Do you mean resistance heaters powered by AC?

Hydrodynamics have built a mechanically driven cavitation heater for years.  At one time they thought it was overunity because they did their calculations based on the wrong feed water temperature.  If you want to heat efficiently, then no matter what you use as the heat source, you need to insulate that and your heated output from the local environment.

Do you mean these guys: https://m.youtube.com/watch?v=yh_-DUKQ4Uw ?

And what about this solution:
https://m.youtube.com/watch?v=A5llLsfZYXw does anyone knows how to build this one?

As long as I saw the frequency is something that could bring overunity... As start I found very interesting the chladni plate and cymatics and vortex coil all working with frequency so maybe the rotation frequency of motor could be solution to gain overunity or better results, but of course then we are going into the beter motor design to use less elecrticity.

I think we all saw the qeg, maybe that could be solution? But again then it is not making better this kind of heater... But only combination of using engine....

Yes, Griggs is the guy behind hydrodynamics now proven under unity water heater.  Griggs and many observers fooled themselves by plugging the wrong numbers into their equations.  Hall Puthoff of Earth Tech International figrued out the mistake over ten years ago and published a paper on it.

I am sorry but that is all so much nonsense.

I have resistive heater 2000W for 230AC 50hz current. Can I power it by pure DC if I know the resistance of heater ?    Any problems ? Do you know if somebody tested the solution of such heater immersed in water to eliminate the sludge of minerals on heater surface ? Like for example high frequency impulses send sometime to the heater maybe ?   If I can power it by pure DC then if I connect negative of DC to the stainless steel container of heater and the negative electrode and all to the grounded rod and I will be checking  the current to the heaters the it would be reletively safe ? What do you think ?

You can power it with 230VDC.  That would be 0.71X the voltage you would have if you applied 230AC full-wave rectified into a capacitor.  You could get close by half-wave rectifying 230VAC.

DO NOT CONNECT THE HEATER CASE TO ANY POTENTIAL OTHER THAN EARTH.  That includes leads that are intended to be at earth potential but may become disconnected from earth due to corrosion, human error, etc.  If you want to connect one side of the heater element to earth do that with a separate dedicated lead at the power supply output to earth.  But absolutely maintain the insulation between the heater element connections and the local safety ground bonding of the element case.  This may not seem intuitive, but it is essential.  You want to guard with your life (in a very real sense) against any possibility of a wiring failure electrifying the water in the heater.  If you electrify the water in your heater, then you can get electrocuted at any of your faucets or in the bath or shower.

As much as I would love to have more efficiency these are the formules that MarkE has given:
Quote
0.830kg/liter * 1.8kJ/kg * 18liters * 73C = 1.96MJ = 0.55kWh
0.55kWh/0.8kWh = 68% efficiency

Teselkoala did the next:
Quote
0.8 kwh = 800 watt-hours
800 watt-hours x 60 minutes/hour x 60 seconds/minute = 2,880,000 watt-seconds or Joules of energy.

Using rough figures for mineral oil: Specific heat 1.67 J/gram-degree, density 0.85 gm/ml
So 18 liters of oil would weigh about 18000 ml x 0.85 gm/ml = 15,300 gm

To raise this amount of oil by (95-22) = 73 degrees should then take about
15,300 gm x 73 degrees x 1.67 J/gm-degree = 1,865,223 Joules of energy

And 17 minutes = 1020 seconds, so the power needed, if all power goes into the oil, is about 1,865,223 Joules / 1020 seconds = 1829 Watts.

1829 Watts applied for 17 minutes / 60 minutes/hour = 0.28 hour is therefore about 1.829 kW x 0.28 hour = 0.512 kWh of energy.

So, if all applied power goes into heating the oil, it would take about 0.512 kWh. But it actually took 0.8 kWh. So the efficiency is about 0.512/0.8 = 0.64 or 64 percent.

And if this is true then we have around 64 or 67 % of the efficiency.......

the live video of how much it used to reach 95 Celsius you can see it at: https://www.youtube.com/watch?v=KWzhLtqdKVE

So if anyone can say that this efficiency percentage is not true please replay and if you think about building one:

DO NOT begin before you see our experience that we shared on https://emolio.com/Magnetic-Heater , so you can see what challenges you will meet!

as for now this post is then closed :)

MarkE ,Thank You! AS it become much offtopic here I sent you PW message, I appreciate your response.
