Steorn Preparing for Hephaheat Release?

I have been keeping my eye on the progress of Steorn, who back in 2006 announced they had discovered a way to create energy through magnetic interactions, a process they called Orbo.

After making a lot of noise and not delivering (e.g. a demo failure and a thumbs-down from a scientific jury), they basically disappeared from the public eye and haven’t made many public announcements for years.CEO Shaun McCarthy has given a few interviews and made some updates over the years, often on Facebook.

From postings today and yesterday, it looks like Steorn may be getting ready to launch a heating heating system named Hephaheat — which they say is a technology ‘based on orbo interactions.’

Hephaheat is described as a “low frequency induction heating . . . using induction systems without the need for additional expensive power supplies,” and it is planned to be used in commercial and domestic water heaters, delivering on-demand hot water at temperatures ranging from 38-100C. Steorn says the advantages over traditional water heaters are the compact size, controlability and low cost of energy. (McCarthy has said that it will provide energy at 1/6 of the cost of traditional water heaters).

Today, on Facebook, McCarthy posted a picture of what he describes as a Hephaheater in its case:


Yesterday he posted a video of what he said were people making Hephaheaters — pouring molten metals into sand molds. See here. From the looks it I would guess the heaters are between 2-3 feet high.

From what McCarthy has said in the past, these water heaters will be produced and marketed by two major water heater manufacturers — Steorn has always said that it will license its technology, not be a manufacturer.

We will have to wait for more information, but it seems to me that if Steorn delivers a working product which can deliver hot water cheaply, they could be competitive with LENR in some instances — and get into the domestic market before any LENR products show up there. While Steorn says Hephaheat is based on Orbo technology it doesn’t sound like it will be marketed as an overunity product — just a lower cost domestic water heater.

As always, I watch Steorn developments with interest, but still await more confirmation in regards to the validity of their claims.

    No, it does not mean greater efficiency in heating water. It means greater efficiency in not losing heat during storage of hot water, and not losing heat in the transfer of hot water across long copper pipes. The High Current hot water heater is right next to where you bathe or otherwise use the water. More efficient at placing you, the electricity and the water closer together in time and space.

    • Fortyniner

      Also, as they state on their web page, “Charge on night electricity rates”.

      The 1/6 claim is almost certainly a (probably optimistic) theoretical combination of all these factors, set against a ‘worst possible case’ such as an uninsulated immersion heater tank located in a cold, draughty room 50 feet from the point of use!

  • Fortyniner

    What claims? That their ‘Hephaheat’ water boiler uses an induction heating system? Or that it is more economical than tank storage or on-demand systems, and more compact than comparable boilers? It seems reasonable to expect that these claims will turn out to be true.

  • Guga

    That ‘s a maximum flow rate. There is no data how warm that water would be. Of course you would only get a little warm water after short heating. They don’t claim anything else.

  • ecatworld

    The same can be said of the E-Cat — the ones driven by electricity. I guess it all comes down to whether the end user can save money by using such a system.

    • Maxfield Q Norse

      And live.

  • Fortyniner

    I’m at rather a loss to understand why people should think that. There is nothing in Steorn’s literature to suggest O/U claims, and absolutely nothing new about the technology. Induction heating is well understood, has been used for years in industry and in domestic induction hotplates. It is close to 100% efficient, but can’t be any more than that as it is simply an energy transfer method.

    Allowing a safety margin to avoid blowing 13A fuses, even an ordinary ring main can supply 2.5kW (10A) – adequate for a process heater that is designed to gently heat milk or other liquids that could be degraded by contact with a resistance heater casing. That, along with its compact size, are the ‘selling points’ of this device – and that’s all.

    It would be great if it were otherwise, but sadly this is not a competitor for cold fusion.

    What great performance do you mean? They are describing a replacement for a regular boiler. I have a normal one at home that heats at night. 1500W easily are enough to heat water for a whole family during the night.

    Steorn has done some strange other things. But over the years I never saw any information on their website claiming that overunity or something magical was going on in their Hephaheat system. The main advantage over a regular boiler is that it is a lot smaller and can already deliver well heated water after a short heating period. Both interesting.

    LOL, they finally hired a good proof reader!!!

    • Maxfield Q Norse

      They were finally able to take international calls again without being harassed.

    Sure you can generate heat via induction at mains frequency. Just imagen: You have a one phase motor (with a capacitor to generate more or less a three phase system). You hold the rotor so it cannot start running. The rotor will become very hot and you can heat water with it. When you design this principle properly, you would heat the metal of the container holding the water in a similar way but would not put any iron in contact with the water to avoid also heating the iron, which would make it less efficient (and also avoid rust). The thing is, would that be less expensive or more effective than a simple resistance heater? I do not think so, but let us wait and see.

    • Maxfield Q Norse

      Electrical heaters are 100% efficient.

  • Pekka Janhunen

    “…it doesn’t sound like it will be marketed as an overunity product — just a lower cost domestic water heater.”

    If it’s not claimed to be overunity, why would one expect it to be so? Perhaps the “no need for additional expensive power supplies” means that it uses wall outlet AC to inductively heat water. Inductive heating has a reputation of being typically more efficient than resistive heating.

    I could be wrong, but to me it sounds a classical “aura of mysticism” advertisement trick. In the 1990’s we had a salesman from a (British) software company visiting our lab. The software was for computing and making graphs; standard stuff. They had a demo which made up lottery numbers and drew them in a graph. We were a bit unimpressed and asked him why such demo. He grinned: it sounds good if they can say that “XXX has a lottery programme”. I never quite got it, but maybe such advertisement strategy works with some customers. Heh, maybe it also worked with me as well since I still remember it… except that we didn’t order their product.

    • Fortyniner

      I agree absolutely and have said as much in previous posts. Only Sterling Allen of Peswiki seems to think ‘Hephaheat’ is overunity, and Sean McCarthy of Steorn has not bothered to correct this misaprehension. In fact, some recent videos from Steorn have seemingly implied some kind of anomalous effect – without of course stating anything definite.

      The mechanism of the device is clearly explained on their website, and there is nothing at all mysterious (or for that matter, ‘orbo’-related) about it – its just a 50/60Hz process induction heater (saving the cost of any power converting electronics) that directly uses an AC EM field to heat a metal thermal storage mass.

        It appears OU is implied, but not claiming so requires no proof.
        Another possibility, By using a Block of Iron for storage in an insulated container would result in less heat dissipation verses stored hot water. Savings would be similar to an On Demand water heater. The Iron would also have a higher heat density & take up less space. There’s no way you’d store hot water ay home at 100’C & this delivered temp level implies the Iron core would be at even greater temp.

        A 6 to 1 cost savings would be similar to on demand.
        On demand units are not cheap. Likely this wont be either but, Electric on demand has additional costs. One that I looked into required 3 double 60 amp breakers & whole house units required more. This requires a 200 amp service, of which many in the U.S. have 100 amp service. Older homes still have 60 amp. Upgrading can easily cost $2K. With Steorns system, this could be avoided.

        My home had a 60 amp service & needed upgraded anyway. I spent an additional $30 while I was at it and installed a 200 amp service.just in case I needed it later. Even doing it myself, it still cost $1K for materials.
        If I never need it, I’m out $30. But If I do need it, I’ve saved a $1K plus on another upgrade.. I Still haven’t decide whether to go with Gas or Electric on demand.

        • Fortyniner

          Yes, it’s a heat storage device. So as long as average demand does not exceed maximum input, it is able to ‘spread the load’ by recharging the thermal store continuously (as opposed to ‘on demand’ systems).

    • Omega Z

      Advertising/Marketing is everything. Especially for the consumer who doesn’t comprehend technology terms.
      Think Megapixel wars where people purchase devices far exceeding their needs or use & not understanding that the cmos sensor itself is actually the more important component as to the quality of the pixels.

      3G or 4G phones. So many think this is Gigabit or Gigabyte data transfer speed, knowing neither the difference between Bit/Byte and argue with you when you try to explain the G=Generation & has little to do with the former. You’ll actually find most sales persons also don’t understand it & some who purposely let you think as you may. Sales is Sales.

      That said, I think there may be some type of OU involved, but not claiming as such requires no proof of such. If it saves consumers money(Or Not), they will buy it.

  • Guru

    For sure, they are in hot preparation for HephaHeat world launch.
    My candidates are: Rheem for U.S. and Bosch or Vaillant or Ariston for Europe.

    After 8 years of this thriller Steorn boys deserve some glory and money.
