Installation of ventilation for a basement in a garage not intended for storage of supplies
When installing such ventilation, the air temperature does not matter, and therefore its inflow can be carried out from the street. But it is worth understanding that a reflector or a fine mesh on the external pipe should still be installed. This is done to prevent snow and rain from getting into the supply ventilation pipe. Another difference is that there is no need to place a container with water in the basement. After all, no humidity is required to store any things and equipment.

Also, some DIYers advise: before making ventilation in the basement of the garage, you should also think about the function of heating the supplied air. It is not difficult to do, but for this you will need some additional parts, namely:

A nichrome spiral from a regular 220 V electric stove;
Two sheets of flat slate, measuring 1.5×1.5 m;
A fan that can be installed inside a plastic honduras mobile database or at its end in the basement.
It is also important to choose the place where the heating equipment will be installed. The order of actions for making the heater will be as follows. First, you need to place a nichrome spiral inside an asbestos-cement pipe, and install the pipe itself on some stops. Also, for safety reasons, you need to fix the slate on the wall and floor at the installation site. Next, it should be included in the air intake system. In this case, a fan is installed in the basement, which will draw air inside. And now all that remains is to connect the fan and the pipe with the heating element to the network.

In this garage, both the supply and exhaust systems have already been installed.

Important! It is not advisable to leave such a structure unattended for a long time. And yet it can be made safe. To do this, it is necessary to install a longer spiral or connect two similar heaters in series. In this case, the heating will be much less, and the installation itself is safer. At the same time, the exhaust from the garage basement can be natural. The only task is to correctly calculate the pipe size taking into account the forced inflow.
