Iíve kinda noticed over the years that for some reason during the winter months when everything gets colder that I seem to add twice as much water to the ATO system then during the summer months when itís really hot Ö granted that the whole tank system stays at a constant temperature due to the cooler and heater combo but it just seems kinda weird to me ,Öseems like it should be just the opposite happening,Ö humidity??? Just kinda baffling,ÖLol

Cold air typically has lower humidity than warm air, because warm air can store more water vapour than cold. That low capacity/ low humidity air comes into your house where its presumably warmer and its capacity increases as the air warms up.

More evaporation will happen in winter because the air coming in once warmed will be low humidity/ high capacity compared to summer air coming in which is already high humidity/ high humidity.

Terribly explained by me, but what you are experiencing is fairly normal.

Start off with the water in the tank being warmer than the surrounding enviroment. Once you tie in winter conditions, the furnace will suck the humidity out of the air. The same happens with cooler air, but it is much more drastic with the hot dry air we circulate during winter months.
So in Pennsylvania, during non furnace running months I have ~4-5 gallons of evaporation on the 135 every other day. When the furnace is on, that can change to every day depending on how low the temp drops. I plan for temps around 15-30 for one bucket of evaporation daily...ish.
