I getcha. I'm just worried because what if you are using a low watt density element? Loopie has convinced me to swap to an ultra low. But he also said that if I recirc with an ultra low, I may never be able to get it to boil at all.
I don't want to add too little to my system and ruin more batches, but I also don't want to add too much to my system and make my beer making difficult or impossible.
I'm inclined to add an ultra low, add an SCR, and add the ability to recirc if I want. Then, try all 3. If I can't get it to boil, then I stop recirculation and never use it.
What's that old saying? "Better to have it and not need it than need it and not have it". So, add all the abilities and try them all at the same time... Then if it doesn't work, whittle down my options until it works. Probably a time waster up front, but at least it gives peace of mind
