As the importer of these fine heaters, I have tested all models and the
HS2000 is dramatically quieter than the previous models. Propex has achieved
this by reducing fan speed slightly and increasing heat output. The fan
speed is regulated by an internal voltage regulator so that changes in input
voltage don't effect fan speed. The HS2000 fan does run at a higher speed
initally in the first 30 seconds or so of the warmup stage, then settles
into the quiet mode. I've noticed the warmup stage is also shorter than
previous models.
