The tube has a finite life time (probably less than 7 years of on-time, maybe as low as 3 years) and costs a BUNCH to replace.  I only run mine when I need to.  I warm mine up overnight before I use it to let it stabilize.
Plus make sure you run it for a day or two every 6 months or so to keep the tube pumped down.
