Laing DDC+ and Laing DDC pump Q's

is the Laing DDC the same as the Laing DDC+ with just a wattage increase?

Laing DDC

(9W) Maximum Head: 13.05 ft (4 m)

Noise Level (Swiftech's Results): 24 ~ 26 dBA in a quiet room @ 2'

Laing DDC+

(18W) Maximum Head: 20.2 ft (6.1 m)

Noise Level (Swiftech's Results): 30 ~ 32 dBA in a quiet room @ 2'

The difference is actually more in the motor. It gives better head (no pun) but as a result consumes more power and is slightly noisier.
