I had not seen any report from Andrea Rossi until now about the temperatures that he is achieving with the E-Cat SK.
Here is a Q&A from the Journal of Nuclear Physics today:

Dear Mr. Rossi,
in a former reply you said you have reached a power density with the ecat SK you have never reached before.
What was the highest temperature you reached with the ecat SK ever, and what is the maximum temperature you can operate the ecat SK without damaging the module?
I hope you give us notice when you for the first time will produce electricity. This will be a monumental event.

The max T we reach is around 20 000 °C.
The production of electricity by means of heat is an old and consolidated technology. The difficult is to make the first source of energy, the eventual conversion of it in other forms is not difficult, albeit some efficiency has to be lost.
Temperatures of that magnitude are suitable for pretty much any purpose on can think of. Rossi has mentioned that a major challenge has been to keep the reactor cool enough to avoid a meltdown. He has said that the turbine configuration has provided help with cooling, but he has emphasized that it is not yet ready for commercialization. From Rossi’s reply it sounds like they have not yet generated electricity using the turbine, but that should be a trivial task compared to getting the E-Cat to run the turbine in a reliable way.
