"I find this demonstration disingenuous and self serving." That's an understatement if I ever heard one. What ones aren't?
And I tend to be skeptical with ya. Could be some savings if only one head in even large compartments like the kit/living room/dining. But I doubt it one head. Some saving in smaller material but maybe not depending on pressures. High means nothing in it self. Pump, I would think, drives the cost back up over the saving on material and less heads if possible. We shall see what comes of this. Chris Cahill, P.E.

When firefighters in Jefferson, Md. compared the two systems a few years ago during renovations, they went with the high-pressure mist. That choice saved them more than $100,000." I call BS! How do you save 100K over a traditional sprinkler in a house unless Marioff pays the home owner to put in the water mist system. "When the high-pressure system activates, there is less water damage than with a regular system," explained Sonny Scarff, senior director for corporate fire protection at Marriott. Which takes me back to my original question: If the average total damage to a house equipped with a typical 13D system is around $2000.00 (NFPA numbers) then how much is the actual water damage clean-up part (you still get fire damage and smoke damage with water mist, as well as some water damage--which may be nearly the same anyways because the 3gpm when turned to steam will still saturate the sheetrock), and is it a significant factor when compared to the cost of the installation and the high maintenance? (Well, I guess it is if you're somehow saving 100K in install over a conventional system.) Folks, we need to be critical. As good as these systems work in small compartments, and especially when you have to haul your water, I find this demonstration disingenuous and self serving. Too much real information is left out and that hole allows the presented information to suggest a lot that isn't really shown in the demonstration.
