I mentioned in my first post on this thread that it was nice to meet Matt Flewitt from Cleansmart again. I bought a CFR Perfect Heat off him a few years ago..He had a stand with just his top of the range machine on it - 3 vac.It was a working demo - complete with silencer.Lots of interest in it being shown.What I was impressed with was the heat the inline heater was producing - the brass coupling at the wand was very very hot - and that was from stone cold water in the machine tank.
