I have a shop out behind the house. I heat it with a small contractor cube furnace and generally I like to keep the temp. at 55 F to 60 F since ‘lectricity cost a lot. I hadn’t been in the shop for a few day for various reason so when I went out yesterday the temp was 115 F, I will assume the thermostat on the heater failed. 36 hours later and the temp is still above 60. I have printed a lot of things to hold tools and other items in the shop, one of which was a small shelf that held boxes of small nuts and bolts. It now has a pronounced droop where the boxes used to be.
Damned glass heat temp.
P.S. can’t wait to get the hydro bill next month.
