Inside an advanced digital power saver unit

An unusual variant on the classic power saver boxes designed to scam non-technical people out of cash. This one looks like it was originally designed to be more convincing by having an outlet socket on the front.

On a plus note, the "digital display" is using relatively safe circuitry running its components at sensible power levels.

And a link to a typical listing for the underfloor heating film:-

The film seems to come with crimps for piercing through the copper tape.
Most seems to be for 220-240V but there must be versions for 120V too. The 240V stuff will still heat on 120V but to a lower temperature.
