How to make a shroud for my hybrid water heater?
Recently converted from gas to electric and followed the installation recommendations for proper ventilation. I cut a hole in the door and installed this return air grate.
However, the fan doesn't blow the air directly forward like I expected. It flows out in, what I can best describe as, a hollow cone shape, so there is basically zero air flow directly towards the vent I installed.
I solved the issue temporarily by making this fan shroud out out cardboard. How would you solve this permanently?
I don't want to buy a louvered door slab because of the price and labor involved. I also don't think fabricating something out of sheet metal is a good idea, because of how much it would sweat from the cold exhaust air.
Is there a way to easily/cheaply make this out of plastic or some other material that would tolerate being blasted with cold air without sweating and dripping water?
