I get about the same effect...lot of noise, surprisingly little airflow.
I didn't respond to this thread originally, as the heater seemed to work fine through the winters of western Washington State (which are generally mild).
But last week, I had to take my Versa in for service. I still own a POS '84 Nissan pickup as a backup vehicle, so I drove that to work, instead. The difference in heater capability was astounding. The cabin got uncomfortably HOT within 5-10 minutes of starting out even with the fan on the low setting, something the V is hard-pressed to do without running the fan at full speed.
I don't consider the Versa heater as bad...after all, it does eventually get the cabin up to an acceptable temperature. But it certainly isn't as capable as some cars. I think it's a ducting problem, as it blows plenty of air in the defroster setting. Might be that the lower-footwall outlets are too small; this would explain both the low airflow and the noise.
