okay I've done some reading on here about the topic of proportional vs non-proportional(on/off) and understand the concept of both of them.

I need a t-stat so I'm looking into the Herpstat which I can use either pro or non-pro.

Whoever has a Herpstat, what do you use?

I ask because right in the manual, I looked it up online, under the Non-pro heating it states "This floating method avoids unnecessary wear on the heating system."

What does that mean?? Using pro will wear out the heat tape faster?? the flexwatt tape I'm using will last longer if I use non-pro? the actual t-stat will last longer?

thanks!
