Hello everyone,

I am Andi and new here in the forum. I hope to “meet” some experts here who can help me with my problem.

The problem concerns my garage. But before I get to that, here are the details of my garage.

The garage has a floor area of about 55m² with a small washroom. The largest wall is underground, the right wall is half underground. The left wall is insulated from the outside and has two windows. The garage roof is used as a terrace.

Now to my problem. During the transitional seasons my garage is wet. The humidity is usually above 90%. On some days it is so bad that water runs down the cabinets and walls. If I didn’t know better, I would say that someone tried to extinguish a fire from inside with a garden hose.

An engineer inspected the garage and sold me a dehumidifier. I think it is suitable for a small bathroom, but not for this garage. Ventilation doesn’t really help. In dry weather, I have both garage doors open about 20cm and the side entrance at the other end of the garage is also open. The floor is still practically wet and my tools in the cabinet rust endlessly.

If I heat the garage while working, the humidity quickly goes down to a normal level. Now to my approaches to solving the problem.

- Another ventilation system would cost me at least 1000€ (use questionable)

- Construction dryer costs about 200€ electricity per month

- Heating with wood not possible

- Infrared heating costs about 200€ per month for the size

- Ventilation, as mentioned, without success

My last solution idea, heating via central heating in combination with my existing dehumidifier. Since warm air is known to absorb moisture, the air with the stored moisture would be extracted. Air circulation would thus also be given.

(after the ceiling was insulated)

My question to the experts: Am I wrong with my theory?

Our old garage was always heated (adjacent room was the heating cellar). I never had problems with rust etc. there.

I am very thankful for helpful solutions.

Regards, Andi
