Eliminate moisture under kitchen furniture

I am renovating an old building. The kitchen floor is made of solid stone (marble?). There is no heating in the kitchen. Condensation constantly forms under the kitchen cabinets, so the floor is wet and the new kitchen cabinets are beginning to warp. The house is often unused and completely closed for several weeks; during this time, it gets quite cold because it is built from rubble stone.

How can I get rid of the moisture under the kitchen floor? Does anyone know of heaters / heated ventilations that can be installed under the kitchen cabinets? A new floor with underfloor heating is not an option.

You have already given yourself the answer! In the end, this is clearly about the (mis)relationship between relative humidity and temperature. The entire room or house simply needs to be (A) adequately heated and (B) properly ventilated. Especially if it is unused or unoccupied at times. You cannot outsmart building physics requirements. A heater just for the kitchen cabinet is nonsense. When in doubt, radiators. Costly, but mold is more expensive in the long run.

You are right with the explanation. On the other hand, heating the house all year round when hardly anyone is there doesn't really sound sensible. If no one is there, the dehumidifier runs and does its job quite well. The problem mainly occurs when we start to occupy it, especially since it is still quite cool inside, and the house is located by the water. So, I primarily need a short-term solution for the transitional phases.

Any ideas?
