Enemy #1: Humidity. ...help?

I think your best bet is to create some sort of cover or hood so that you can control the water evaporation in the first place.. then if you need to you can vent that to straight outside using some dryer duct and an exhaust fan. That’ll save a lot of energy over trying to keep the whole basement dry. Putting the exhaust fan on a rheostat so that you can dial the fan speed is even better.. then you can dial it down to right at the point of preventing condensation.. or just keeping a little bit of negative pressure to keep the moisture from leaving the tank.

"The vast majority of mold species require "water activity" levels that are equivalent to material equilibrium moisture contents corresponding to relative humidity of at least 70%. In fact, the great majority of serious, large mold outbreaks inside buildings occur where porous, cellulose-type materials have literally been kept wet by liquid water or sustained condensation."

First, you want to keep each room below 70% relative humidity to avoid mold which is a serious issue.

Second, you want to avoid so much condensation that it is maintained continuously on surface materials.

Otherwise, you should be good.

Obtain a hygrometer. Dehumidifiers are a good choice as others have mentioned if your relative humidity is too high.

Hello; I had humidity issues after moving into my current home a few years ago. My previous home had an oil furnace and no humidity issues during the winter. This house has a heat pump. The first winter room moisture would freeze in ice layers on the inside of my windows. The french doors would form puddles on the floor even tho the glass was double panned.

I did two things that helped. The first was to get a de-humidifer. Another thing that has helped was to place a half inch thick sheet of foam board on the outside glass of my french doors. I used the type with a foil layer on one side. I cut the foam sheet to fit snuggly against the glass. This stopped the formation of ice on the inside. It does not look good but it works.
