using 3v pot for biab small batch

[Moad]

I've recently gone from 20 litre BM to 3v with 100 litre pots. Just wondering if there is any reason I couldn't do a 20 litre biab batch in one of the pots. I'd obviously get a lot of boil off and my dead space is 8 litres. With full volume mash I'd want to start with around 28 litres which gives me around 4lt/kg in the mash after taking dead space out.

I could actually do this in my HLT as its temp controlled by firing the burner on n off.

There must be an obvious reason not to do this?

I recently tried biab in my 50 litre keggle. Went so well I got rid of my esky tun and hlt. You can absolutely use one of your 3v to biab

I can't see any problem.

I'll be using my brand new 95l kettle to do single batches. 8 litres is a lot of dead space though.
