I built the unit and used it for the 2012 season on my 3x12 Force 5, we are adding a piggy back this season and no longer need the pre-heater.  1" manifold with six 3/4" lines.  Total lineal footage is 65 ft.  The drip tray is welded stainless with a 1/2" threaded outlet at one end.  It worked really well, you can expect about 5 gallons of hot water every hour.  This would easily fit a 3 x 10 as well.

Preheater measures aprx 24" wide by 66" long (not including the inlet and outlet feed pipes)
Drip Tray measures aprx 28" x 72"
