I have a small workshop built in an out building that has a wall furnace with a standing pilot light in it. It certainly isn't a high efficiency piece of heating equipment.
I also have a vent-less heater, also standing pilot, that was given to me. I use the vent-less for regular use but kept the wall furnace as backup as well and as the occasional fast heat-up.
Question is:should I leave the the pilots lit in the summer time?
My thought are the pilot with prevent moisture in the units.

By product of combustion is water vapor.

Turn off the pilot.

da, I knew that.
I guess I was over thinking the idea.
Or maybe I just had my head up my, well not in the sunshine.
