Default Manually controlled HERMS

One Question: Can (not is it the best option, but CAN IT BE DONE!) you control a HERMS or RIMS system manually? I would think that HERMS may be easier because to control manually because the water will act as a buffer. I ask because I would like to build a manual HERMS system now and later add controls, but I don't know if it even makes sense to do without the control component.

I built a herms coil that is plumbed to allow a mixture of circulating wort to go thru the coil to add heat, or by pass the coil all together. To use it you need a burner that has pretty good control. In other words, you end up adjusting the water temp in your HLT with a regulator and adjusting the valves all while trying to hit and hold a temp in the MT. You can do it, but you won't set it and forget it for 60 minutes...

That's ok, brewing is my quite time in the garage, LOL. Seriously, I like the thought of constant recirculation, but I am not ready to make the leap towards automation yet. Do you have any pictures or diagrams of your setup?

I am in the same boat as you right now - building a manual HERMS. Until I automate, my plan is to constantly recirculate with no bypass. I am making a coil with the turns spaced a bit that I will place into the heated sparge water tank and control temperature by how much of the coil I submerge.

Now that is a new twist. How will you control the depth?

For now, a string attached to the top bends at the entrance/exit of the coils. Next, it gets looped over a bar then angled out and down to the ground where it is weighted down to keep it firm.

I haven't had a chance at a test run yet. I can't see why I won't be able to hit temps. No immersion - loses temp, full immersion - overshoots temp. Somewhere in there is an equilibrium point.

This is my plan - doing a recirculation in the MLT with direct heat, with me as the control.
