The idea is fair enough, but at £450 per unit to buy (shipping and installation cost to be added you'd presume) and with a running speed up to 1150 rpm (19 turns per second and blattering in our high moisture often salt laden air - how long will bearings/bushes/seals etc last) I'm left wondering how it could be justified on value for money grounds, even with the Hydro's hellacious per unit charges.
