BIAB/HERMS rig questions
So I am in the beginning stages of designing a new brew setup. I want to keep this fairly low cost since I am a broke college student. I want a system that can fulfill the following requirements:
1. Utilize the equipment I have already. Keggle, smallish (16 qt) stainless pot, 50 ft 3/8" immersion chiller, 10 G mash tun, 8 gallon stainless pot, two propane burners (one banjo, one jet)
2. I will be brewing outside in a few different possible locations. I dont want to be tied down to a 240v GFI circuit as this isn't possible at either locations. Propane is ideal as I work at hardware store and can get them filled for free
3. Have some level of temperature control. I want to be able to hit my mash temps consistently.
4. The rig must be mobile and easy to transport in a truck
After searching these forums for days I have finally thought of a concept to meet these requirements.
A BIAB keggle that will recirculate the wort through a HERMS coil housed in the small 16 qt pot. I would use a 1500W 120V heatstick controlled by a Auber PID for temperature control. A march pump will be used to recirculate the mash. The propane burner will heat all of my strike water to the correct temperature and the HERMS will be set to that same temp. I would also like to reconfigure the IC copper to make a instant hot water heater coupled with the jet propane burner. This would get me up to temps much quicker. All of this will be build onto a steel cart with casters and an arm over the keggle to raise and lower the grain basket into the pot.
I got a few questions. First, is BIAB even worth it? How does BIAB beer compare to beer made on a three vessel system? Second, is this HERMS idea just over kill? Third, if I am running the 1500 W stick and one march pump through a 15A service, will I have problems with power consumption. It will be on its own circuit in a garage with nothing else on it.
I hope to get some feedback on this and if it seems feasible I will update with build plans and progress
