Built an extension on our summer cottage. Here we placed a kitchen and washroom/shower. The extension was placed on a new cottage foundation, concrete slab + Leca block foundation. A food/beer cellar 150x150 cm with a ceiling height of about 140 cm was built up (Leca blocks) inside the foundation on a cast concrete slab. Gravel drainage under the entire construction. A floor hatch in the kitchen floor provides access to the beer cellar. In this cellar, the incoming water connection, hydropress, and water filter were placed. We also installed a 50-liter water heater. A ventilation pipe was drawn through the inner cellar wall and out through the outer foundation wall. In the concrete floor, a drainage pipe runs straight down for any water damage.
When the water heater was connected, there were issues with condensation. A lot of water forms on the floor. The temperature holds at about 14°C. Condensation forms both on the cold water pipes/filter/hydropress but also on the colder floor. Only under the water heater is the floor dry. The distance between the water heater and the floor is (about 20-25 cm).
I have blocked the ventilation pipe to prevent warm outside air from coming in. I've placed a "dry ball bucket" but with poor results. What is the best way to achieve a dry, cold cellar?
Insulate cold water pipes/filter/hydropress? Move the water heater?

Yes, the valve is directed towards the floor. However, there is no visible water drip on the floor; on the contrary, the floor has a dry surface under the water heater. But perhaps it's important to lead any possible expansion water out through the wall to the crawl space?
Insulating pipes, filters, and the hydropress should be done, but it also seems to be a problem that the floor/bottom plate is cold and causes warm air to condense.
If I go into the crawl space outside the beer cellar, you can see that the cellar bottom plate is damp on the outside. Maybe I should seal all the vents during the warm season to prevent outdoor air from penetrating and condensing? The floor joists are dry and hydro-isolated against the lecagrund. The ceiling height in the crawl space is about 120 cm.
