I spent some time with it also. Trying out the striker wand and checking out the heat. It was also hooked to a tile tool at 2500 psi and it held about 210-220 on the temp guage on the front panel at a fairly high flow rate. Evidently, the heat exchanger being a combination of strength from the stainless steel and copper made it possible to use that much psi and not break, as well as maintain heat by means of the copper and some kind of dual pass, if my memory is correct. Some other seemingly well thought out inovations as well, just can't remember it all right now.danielc said:How did the SS 870 perform?
