I heat my enclosure just like this, and I and attest it works great... just make sure the hair dryer is not pointing at the build area.

I also agree that you should look for a printer with a direct drive extruder: better precision and can print flexible materials (nylon is semi-flexible).Also look for a printer with an all-metal hotend, so you can print over 240C without problems.
