Hello everyone,
perhaps some of you already have practical experience with electric cars and charging stations. We are about to start the wiring for our new double garage. Attached is a sketch:

Next to the distribution board, there will also be a 16A or 32A outlet. Do you think the number of outlets might be too many? And the main question:
1. Where would you generally place wallboxes? Closer to the garage entrance or inside the garage?
2. For a double garage, would you rather go for two wallboxes?

Only one car will fit inside, with bicycles stored to one side. This way, we avoid the "cramming" issue. If we’re away for a longer period (e.g., on vacation), we can still squeeze the cars in. Ah, so the second car would then be blocking the garage entrance?
When you go on vacation, do you travel by train, plane, or use your parent's car?
Do you have an additional parking space?
Ventilation is definitely necessary if moisture cannot condense somewhere (like on a window).
We don’t have a ventilation system, but there are three “porthole” vents in the garage door where moisture collects.
Just wipe them down occasionally, open the door a little... and that’s usually enough.
The garage is in the basement, outside the building’s thermal envelope, but still insulated.

For vacation, how will you travel then? By train, plane, or dad’s car? We still have an additional parking space/garage, so that wouldn’t be an issue. For vacations, we might sometimes travel by plane or by car. What the future holds in 3, 4, or 5 years, I don’t know. If combustion engine vehicles become increasingly rare and the purchase costs, range, and charging times of electric cars remain unaffordable, traveling by car for holidays could become more challenging.

Does your utility company even approve two wallboxes with 11 kW? I spoke with the utility company. In principle, 22 kW wouldn’t be a problem since there are few or no wallboxes on the street yet. However, it wouldn’t be fair to grant approval to those who apply first while others would have to be left empty-handed. Therefore, the limit is 11 kW, and if I have multiple chargers, I should use a load management system to ensure that the total power drawn never exceeds 11 kW.
Regarding ventilation, I am still having difficulty making a decision to finalize this thread for myself. Have any users installed a decentralised ventilation system in a garage?
I am considering whether it could be one of these devices:
I am considering whether it could be one of these devices:
- A fan for both supply and exhaust ventilation (e.g., Zehnder ComfoSpot 50)
- Two fans, with one supplying fresh air and the other exhausting stale air (e.g., Zehnder ComfoSpot Twin40)
- The ComfoSpot 70 would probably be oversized (~200€ more expensive)

Has anyone here installed a decentralized ventilation system in a garage?Besides investment, operating, and maintenance costs, what benefits do you expect from an actively ventilated garage? I would have said that 2-4 wall vents would be sufficient.Similar topics
