As a rookie 1st year, temps climbing near 80 this week. I come home in the evening & it's 75* inside and I catch myself setting here & hard to resist firing the baby up. Sure don't need to heat it up inside and I have still fired er up and shut it down a few hrs later, before going to bed. May just have to unhook her and take it out for a complete tear down/cleaning. Burned thru 3 1/2ton---1/2ton still left. I'll have to document the improvements made at the beginning of the season and share what worked to my advantage.
