They may have added a block heater since I took that picture, but warm moist air will always condense on cold metal and glass:
It really needs a dehumidifier…

Porcelain is pretty good at condensation, too. Had a 2AM nature call after painting in the house a few weeks ago, and found that the floor below the toilet tank was very wet. Not a leak, but the high humidity in the house from the paint combined with low air and very low water temps to make quite a rainfall. It doesn’t help that the toilet is the closest fixture to get water from the feed under the house, so with cold exterior temps, I had the perfect storm.
Temporary solution is to keep the bath door open at night and to override the setback until the humidity drops (our walls soak up a lot of paint due to some funky texturing). I’m mulling over extending the water line to that toilet to collect heat from the house, but between under-floor insulation and the plastic crimp tubing system manufactured homes use, I’d rather not…
You know you’re crazy, right? We paint the walls & doors only during open-window weather, lest we expire from the fumes. Even latex paint is nasty; enamel is outdoors-only. Phew!
Nah, I’m “eccentric”. [grin] We only use latex paint in the house (the shop/ barn is for the stinky stuff), and we use quick-drying PVA sealer instead of a true primer. Not sure about east coast paints, but after the California Air Resources Board (CARB) got through regulating paint, stuff here on the Left coast can be managed with a laundry room vent fan. (The first pass of low VOC paint was horrible to work with, but it got debugged.) ‘Sides, fresh paint is a lot less nasty than the dust found under the evicted carpet padding.
I’ll not belabor the time I used methylene chloride on a wall 30 years ago. The dain bramage healed, I think…
‘Nuff said. [shudder]
The cold glass is the dehumidifier. As you can see, it’s working perfectly.
It just that they connect the dehumidifier sump to the ambient air inside the case: there must be a nice puddle on the bottom of that box!
Which I’ve done, too, in the basement. Mary uses dehumidifier water for the house plants, so I dump the catch pan into 6 gal buckets and sometimes forget to put the lid on again.
