Coldmetal, If I see a message of someone saying he can save 2 % or 5% on energy costs, then I'm really interested.
But if someone claims savings from 20 up to 30%, then we all, 20 to 40 years in business, technicians into all our bones must be real fools, the worst technicians ever walked around on this planet or ....(fill in yourself)
As said previously, you can't change nature laws. And you never gave in your 4 posts one valid point which indicates even 1% saving. You're clearly a salesperson and not a technician who understands how a machine really can save energy. Start/stops decrease is not one of these.
There's no cynicism in the posts of us, but there's a lot of criticism in it.
