Friction Heater used to Heat a House

at 2:24 pm. Filed under DIY Hacks


oilpiggy is heating his 1200 square foot house with his home made friction heater. The heater is simply located in a central area at this time and it naturally radiates heat to the house. He has it plugged into a smart thermostat that controls the run time and temperature of the heater based on time of day. Currently he is heating his house to 75 degrees (with an outside temperature of 45 degrees) for about $30 per month. His old heating system used to cost him $200 a month. You can see a newer version being tested below and check out the other videos here to see how they are built.

    Be warned that the author seems to think this device has an efficiency over 100% and readily points people to “overunity” forums.

  2. Polaczek Says:

    Um, what’s the advantage over resistive heating?

  3. RBMK Says:

    I think that main advantage is that you can use rotational power from mechanical wind turbine, water wheel or turbine. There are no loses from generators and transmission wires, but there are losses from bearings on the shaft.

  4. ChalkBored Says:

    So which video has the internals of the device in it?

    My best guess is that it uses a stator to churn oil and make heat, but I don’t want to sit through 10 videos of the guy talking about how great it is instead of how it works.

  5. Frank Says:

    IMHO, the company meter only counts resistive power and not reactive power. So he thinks he’s getting free energy, where’s only stealing it.

  6. Alan Parekh Says:

    Hi Chalkbored,

    You can see it here:

  7. ChalkBored Says:

    Thanks, Alan.

  8. JD Says:

    Seriously Alan Parekh, I thought you were smarter than this. Why are you posting overunity crap like this? It makes people stupid!

  9. Chef Says:

    Can someone explain to me why this is a better idea than resistive heating?

  10. George Johnson Says:

    I don’t know…… I learned the hard way, energy, is energy. Doesn’t matter if you got 1V x 10A, or 10V x 1A…. you STILL got 10 watts. Minus losses, it stays the same, all the time.

    This guy is saying it’s $30 worth of energy, to do what it used to take $200? Even if it was just purely a heating element, that just doesn’t add up.
    I tend to go with Frank on this. I remember people adding stuff to their meters to make them more reactive instead of just resistive. Seems to me, the power company frowns on this when people do it, but businesses were doing this with their help. Most large buildings have these reactive loads to switch in and out to balance the system out (or used to). But, I don’t know where that’s coming in here, this is just a motor plugged in.

    Energy, being energy, I just can’t see spending $30 to heat your home unless you have great insulation, and some hell fire conversion efficiency. That’s like $1 a day of electrical power. That just isn’t that much.
    Not saying it ain’t so, just hard to believe. Friction, notoriously inefficient, is more efficient than purely resistive heating? By what, a factor of about five?

  11. Konstantin Says:

    All heaters are 100% efficient and you can’t get more than that without something special, like fusion or fission. The “losses” from the circuitry turn into heat, which is what you want from the heater anyway.

  12. Andreas B. Says:

    This “friction” heater is bogus. Most likely what that guy has done is simply to lower temeperature and decreasing the heated volume and/or the time he heated.

    Mostly the energy extracted from your wall plug is more expensive than using the chemical energy stored in fossil fuels. From an efficiency point of view this is why it is better to heat your homes with fossil fuels rather than electricity, because when using electricity there are conversion and transmission steps in between, and every step means the efficiency decreases.

  13. Roman Says:

    I used to like this site. I can’t believe this was published. Obviously this is not more efficient than resistive heating. But it’s noisy, prone to fail, and take a lot more of resources and energy to build it. In short: it’s a stupid machine. If it’s objetive is to heating, course. If it’s objetive is to create a complicated noisy machine to heat, ok, I like. I’m use to build useless stuff. But there is no comment from “Hacked Gadgets” and that is what I dislike. I’m really tired of all this pseudo science of free energy. We have all this technology in communications, which put at reach mostly everyone a LOT of scientific knowledge, but some people are still in middle ages.

  14. Alan Parekh Says:

    Hi Roman and JD,

    Thanks for the feedback. I am not saying this is some fantastic new thing that everyone should run out and build one (people here are educated and will do their own research and not follow false claim fads). I find these crazy claims of “free energy” interesting. Just like these ones:

    If anything these articles will serve as a public service to anyone who could get caught spending their hard earned money on this stuff!

  15. Roman Says:

    Alen thanks for the response!. Yes, you are right, the people should make their own research. But a little comment can orient the people to investigate, something like: Warning, could be another “free energy” scam, but looks like an interesting heater
    But it’s your site, and I’m know, I’m too sensitive to this kind of things.
    I’ll will still coming back 😉

  16. Tony Says:

    As @RBMK said, it’d be useful IF it was powered mechanically (windmill etc) rather than an electric motor. It’d be (a bit) more efficient (and cheaper) then using the windmill to make electricity to run a heater.
    The current device has the same efficiency as a resistive element (arguably 100%) as an loesses wind up as heat. Stupid idea, of course, and it’s more expensive, needs more maintenance, noisier, etc.

  17. Markus Says:

    If all it takes to get on this site is a noisy machine with bogus claims: i have a broken stereo here that’s also a time machine. want some pictures?

    anyway, i hate the term “free energy”.
    why is wind energy “free energy”? you need to build the turbine, the generator and so on. so to make it usable is NOT free.
    on there terms coal is free energy! it just lies around in the ground. you just have to dig it up and there you go! which is a lot less expensive (if it isn’t in too deep) and complicated. and that is the reason why mankind had used it thousands of years before anybody built the first wind turbine/solar cell.
    so nothing in free energy is free.
    not even free as in freedom. build a 20 meter tall wind turbine and wait until somebody asks you if you’ve got a planning permission 🙂

  18. JD Says:

    Alan, the problem I’m having with this, is “Currently he is heating his house to 75 degrees (with an outside temperature of 45 degrees) for about $30 per month. His old heating system used to cost him $200 a month”

    For me, that sounds like you believe him. Had you instead said that “he claims”, then the story would have been different.

    In my opinion, this article should never have been posted. There is no reason to promote stupidity.. sure it’s fun to see people hurt themselves, but promoting overunity is only making the world more stupid.

  19. asdf Says:

    After reading this article I took the time to carefully inspect everything posted by this gentleman. I can now rest peacefully knowing it was not something novel. Simply another lazy amateur ‘rebel scientist’ who thinks they discovered something missed by the thousands of more diligent intellectuals who preceded them. Unfortunately because of this article’s wording, I have wasted my time.

  20. Oilpiggy Says:

    Well after reading most of the posts on this site I have many questions,., I am the person who has made this Friction style heater! I have never claimed Over-unity or what ever you want to call it. I am Simply a guy that has built a friction heater.! and was sharing,.! The only thing I have learned from all your post’s is that you are all just key board queens not builders…. Watch all my YT Vids and maybe, just maybe you may help or understand what is going on.

    Keep burning you oils!!!!

  21. Oilpiggy Says:

    One more thing, Why do so many people try to cut down people who simply try to share?

    I will ask all of you people who posted on this page. What have you built? and did you share it?
    If you have not done both of 2 things then you are part of the problem not the solution.

    If you have any questions to ask me about what I have learned about friction heating feel free to ask me anytime @ frictionheater@hotmail.com

    This has been a fun build and I have meet a lot of good people from it. I thank all who helped with this build, for the people who would like to know what the new friction heater looks like look at, http://www.youtube.com/watch?v=ErDldDkQ7wE and http://www.youtube.com/watch?v=NeO4qNz6MB0

    Thank you
    Gabriel Peterson

  22. Polaczek Says:

    If the amount of electrical energy you (since you are using wall power/electrical generator) put is what you get out in terms of heat, then what the advantage of a resistive heater which has minimal maintenance costs. You seem to avoid this question continuously, instead you can go on the offence and attack all the people making an input. If you truely want to further yourself you can actually try to contribute to the discussion and not just show that the world you are able to slap some parts together.

    If you can’t handle the criticism, then don’t post your work on the internet for everyone to judge.

  23. Konstantin Says:

    Okay, so what are you claiming? Why would anyone want to build one of these devices in the first place?
    Please do tell

  24. aaron Says:

    yeah why not just heat your house with fifteen 1800 watt hair dryers since electrical heat is 100% eff. right ??? if this guy really believes his own *******t he is f-ing crazy

  25. Tom Downunder Says:

    I have taken the first steps to building a friction heater. After a very long search, I sourced the outer aluminum for the casing, some bearings, and tomorrow I will get the motor & variable frequency drive, and send drawings to the laser cutter. Thanks “oilpiggy” for emailing me the diagrams with measurements.

  26. Ron Starbuck Says:

    At 16 cents a kwh, this should be costing about $100/month to run 24 hours a day assuming 860 watts in the video is constant. Is my math correct ($.16 x .86kw x 24hrs x 31days)

  27. Davia Says:

    Certainly 3 AH for 1KW + of heat is better than what runs now in the house. Friction heat doesn’t completely fit the thermodynamics model, but I think it works extremely well due to rotation and vibration physics. We built a little one with decent success and attempting to make something like the above. TD has a good idea about using aluminum over other metals I think. The costs mentioned above could be even better with applying more items around the house utilizing convection/conduction, maybe some water pipes extending out. Fun to play with anyway.
