It will probably be about 1100 watts then, as our electricity is 230 volts these days. The motor will probably be just over 1 HP.
I wish they didn't have a "specially made for QVC" model, the reduced guarantee sounds like they made a "cheap and nasty" one to get the price low (well, not actually LOW, but more profit for Q). I think the IW model was a standard one.
It shouldn't dim the lights though, which is why I suggested trying a different socket above. The lights should be on a different mains circuit to the sockets in any case.
I don't see the point in running it for 6 minutes to heat up soup. I would just liquidise the ingredients then put it into a saucepan to heat, much more efficient use of energy.
Its supposed to be a 2hp motor, all the 'Creations' models have a five year warranty, as does the Aspire, as sold by Lakeland and both are on the Vitamix website, with 5 year warranties. Its the Total Nutrition Centre versions which have 7 year warranties, they all have the same motor, main difference is jug size, the TNC has a soft touch handle and controls and is more expensive. I think it was the TNC that Ideal World sold.
