To chill or not?

[Syncman]

2 gal Electric BIAB recirc.

Because I only do 2 gal brews, the level of the wort is not too high above the element. Not much space to use a chiller. I tried building one that lays flat on the bottom, with a "tunnel" to bridge the element. I was wondering if there was a downside to just letting it cool by itself?

Yes, there are disadvantages to "no chill", but some brewers do still skip the chilling step and work around the issues.

No chill even though it sounds like a good idea would be my last resort for chilling.
I haven’t had an immersion chiller for over 20 years. Since you have a pump I would invest in a stainless CFC or a plate chiller. I have both but prefer the CFC.
An ice bath would be my go to for a small batch without the CFC or plate chiller.
I believe the faster the chill the betterThe product
