Andrea Rossi back from spending Thanksgiving in the United States has made a number of interesting statements on his blog. The most interesting of these involves the home e-cat boiler which would be used for both heating and water heating.

In a post Rossi revealed that he and is partners at Hydrofusion are collecting orders but not money for a 10 kilowatt (kilowatts of heat not electricity). The estimated cost for the units would be 400 euros ($521 USD) a piece. He did not say when these would be available. Rossi will only accept orders if he gets 10,000 names on the list. Here is what he said in response to a question from Chile on December 9.
Dear Felipe From Chile:
You are right, we are organizing this.
BY THE WAY: WE COLLECT FROM NOW THE NAMES OF ALL THE PERSONS OR ENITITES INTERESTED TO BUY AN E-CAT OF 10 KW. IF WE WILL REACH 10,000 NAMES IN THE LIST, THE PERSONS IN THE WAITING LIST WILL HAVE THE RIGHT TO CONFIRM OR NOT THEIR ORDER AT 400 EURO/THERMAL KW. DO NOT SEND MONEY, WE WILL ACCEPT THE ORDERS ONLY IF WE WILL REACH 10,000 NAMES IN THE WAITING LIST, COMBINING OUR LIST WITH THE WAITING LIST ORGANIZED BY OUR BROTHERS OF HYDROFUSION .
WARM REGARDS,
ANDREA ROSSI, LEONARDO CORP. (PRESIDENT)
This would indicate that Rossi is fairly confident in his technology. If he took orders for something and didn’t deliver it he would look pretty foolish. He could also be prosecuted for fraud or sued. Note he isn’t taking money. Rossi confirmed that e-cat is an effective heating technology

Dear Gaifas:
Yes, we heat up the factory where we work with an E-Cat.
Warm Regards,
A.R.
Note Rossi has provided no proof of this although he’s said it a number of times.
This would also seem to indicate that Rossi has or is close to getting an international, US or European Union patent. He would need one to protect his secrets if he went into mass production. Rossi already has an Italian patent for e-cat.
Even though it looks like e-cat is an effective heating system, production of electricity seems to be a few years away. Rossi admitted that it would take around 1 or 1.5 kilowatts of electricity to produce 3 kilowatts of electricity with present e-cat technology. That does not seem very efficient to me.

Dear Aussie Guy:
To make 1 thermal MWh/h of energy you will need 160 kWh/h (thermal or electric). This system will yield 300-330 kWh/h of electric energy. This, with the best available conversion system we got so far. In sustained mode this can be upgraded, but only in a real scenario we can get real numbers. For now, conservatively, is better take these numbers.
Warm Regards,
A.R.
He also stated that the COP or coefficient of performance (a formula used to calculate the amount of energy needed for electricity or heat production) in an e-cat is two.

Dear Gherardo:
If you make electric energy using electric energy in our system the guaranteed COP is 2, so far.
Warm Regards,
A.R.
It looks like Rossi has a lot more work to do on his invention. Yet it also looks like an e-cat boiler for home heat and water heating could soon be a reality. If you want on the list for a home e-cat you can send a note to this e-email.

Rossi also stated that e-cat production has begun in the US but gave details or corroboration.

400€ per thermal KW not 400€ a piece. Thats 4000 €
If eCat uses its own electricity, the electricity input-output ratio is 1:zillion. That 1:2 ratio means only that its power generatin cpacity is halved. What count is heat-in to electricity-out ratio, and this is 1:6 or about 15%, similar to that of steam engine, but with fuel costing next to nothing.
Of course even a conservative COP of 2 is close to energy for free. If an e-cat gets you twice the input power, just feed it to two more e-cats (e.g. of two neighbors) and you get four times the input power (two neighbors would share the cost of 3 units but have a COP 4 each), and so on.. a neighborhood of a thousand people (1024) served by a cascade of 10 devices would have a COP of 1000 (a good approximation of energy for free) and each shareholder would bear the cost of two e-cats. Just need to add some shared maintenance cost and some redundancy provisions, to avoid a blackout on an entire neighborhood should a failure occur on the first stages.
Where are you getting 400 euros a piece? According to the info up there, it’s 400 per KW. For a 10KW unit, that would be 4000 euros.
But I would love to get a 10KW unit for 400.
“The estimated cost for the units would be 400 euros ($521 USD) a piece.”
The cost of the unit will be 4.000 Euros, not 400. 400 Euros is the cost for 1 (one) kW thermal.
At a cost of 400 euros per kilowatt of heat, for the 10 kilowatt e-cat it would cost home users 4000 euros, equal to 400 per kilowatt times 10.
THE PERSONS IN THE WAITING LIST WILL HAVE THE RIGHT TO CONFIRM OR NOT THEIR ORDER AT 400 EURO/THERMAL KW.
COP is better than 6 and not 2 ! (http://www.businessdictionary.com/definition/coefficient-of-performance-COP.html)
To overcome Coulomb repulsion of the nuclei a pressure of 10^27 Pascal is needed.
It is equivalent to a pressure of 10 000 000 000 000 000 000 000 Bar.
How chemical assistance, ever, can help overcome this repulsion ?
However, in my heart, I hope it is true what they claim …
typo: ” The estimated cost for the units would be 400 euros ($521 USD) a piece. ”
Since that is the price per kilowatt it should read “4000 euros ($5210 USD) a piece. “
Thanks for pointing out the error. Please note this is merely an estimate. We will not know how much it costs until we see it up and running.
from text above …
… estimated cost for the units would be 400 euros ($521 USD) a piece
Wrong, not 400 euros a piece but per 1 KW of power,
10kW x 400 Eu = 4000 Eu per piece (5210 USD)
Regards T.D.
As has been stated many times, the cost to produce a LENR heater is considerably less than Rossi will be initially selling them for – and it ought to be obvious that Rossi is not going to delay production until he gets patient protection. In other words, we can expect dramatically lower prices on LENR generators in the next couple of years.
We don’t know what the cost will be. Note Rossi will need money to set up initial production. So the initial price will be much higher. It will fall. Just as the prices fall for any new technology.
