OK,
So it plugs into the wall.
How does that help my permanently connected Hot Water Cylinder and my permanently connected Range?.
The first being rated at 3kW and the latter rated at 12kW.
Having a thing like that plugged into a wall socket is going to do not a great deal for all of my loads.
I have to agree Paul, it sounds like the good (snake) oil to me!. [Linked Image]
