I have just done some reading on this. It is a BZ-40P - MG.
It has a 3.4L copper boiler and the wattage is 2550W using two heating elements. It does operate off a normal power point as I saw it in operation off one.
This thing is worth $1950USD!! I saw it on the espresso on line website for this price with shipping extra.
This thing is a friggin monster yet I was watching it come up to temperature. It only takes about 10 minutes and if you run a blank shot it is ready to go! I think them big elements help here.
It would sell for $3000 easily here in Australia, allowing for the exchange rate and the fact that most things cost more here.
The guy who was selling it to me was saying that he thought it was strange that it said 3.4L boiler on the front when it was 1.5L on the internet where he looked it up.
He just moved into this house and the machine was there previously, left by the owner. There was a hole in the granite bench where it was plumbed in. It was a million dollar house so I guess it is not a big deal to them.
So there you go, in the right place at the right time.
Cant believe my luck.
