    The last two years I have used the kitchen stove to heat 3.5 gallons of strike water to mash in a 5 gallon cooler MLT. Run off into the keggle and add top up water and extract. I want to get a away from that for a variety of reasons, the first of which is we just bought a glasstop and I'm not allowed anymore. Sooooooooooo I need some help with working out the deets for an e-HLT.

    Project Scope: Convert keggle into an E-HLT with a temp controller.
    Short term goal: Gain ability to heat a large enough volume of water to complete all grain 10 gallon batches.
    Long term goal: Plumb with MLT and kettle to bring all component's into one consolidated "rig" controlled through one GUI.
    Budget: $200 (for the HLT)
    Current on hand resources relative to this project: Keggle with site glass and valve. Kent QDs to utilize single pump.

    I assume you have 220VAC power available... what amperage?

    What are you looking for in terms of ramp rates? Are you planning on using it as a HERMS heat source in the future is is that not in the plan? (simpler if the answer is no)

    For temp control do you want it to be a self contained dedicated temp controller or do you want to use an integrated, software based controller?

    220 yes. At least 30.
    Ramp rates aren't a large concern. 8 gallons to 180 in under 20 minutes?
    No plans for HERMS at a later date.
    As far as control goes, it could be as simple on/off and dedicated. Software based would lead well into other integration, but that isn't a necessity for this project unless it's simplish and cheapish.

    How do you feel about outside? Knowing a little about you, you should look into rocket stoves....or tap into you wood furnace.

    Tapping into the wood stove is another option. I've thought about it and I like the idea if I can hard plumb it. Right now I just want an HLT so I can brew dammit.

    I say start simple.

    A couple ssrs a good heater element and a simple controller. We could use process machines to control it if you want to use a laptop for a gui. Otherwise a dedicated pid controller can be had on ebay for cheap

    Simple is more likely to happen, I completely agree.

    I love the idea of using Process Machines because I want to be there eventually and it would be badass. If it add a level of cost or complexity that reduces the likelihood of success I say PID.

    Buuut. Process Machines would add a unique dimension to this project. I say we go that route.

    Let me look into where things are with the Process Machines.

    With process machines:
    need a laptop to control.
    Need a usb cable to connect
    need a little black box for the brains / low voltage power supply
    Need a power interface / relay enclosure
    need a temp sensor

    with a dedicated pid
    need the pid unit
    need a panel to mount the unit to
    need a low voltage power supply for relays
    need power interface / relay enclosure
    need temp sensor

    Cost wise the dedicated pid may be a touch cheaper if you go with the elcheapo ebay unit, but if you buy a love or johnson brand controller I could do the PM version for a bit less...

    If cost is close, I'd rather go PM. Unless there is a LOT more work involved somehow. But I'm guessing not?

    So that brings us here. I have the laptop. And probably a USB cable, but I might want a longer one. I'll check the circuit I'm planning to use also.

    30 amp circuit going to the dryer. That's the easiest one to get where I need to go.

    However, there is a spot in my panel that has been recently vacated by the water heater that I no longer use. I could put in whatever I want. I could put a 50 amp circuit in right there and make the pigtail for the HLT long enough to go back to that plug. That would require a 30' cord though where using the dryer outlet would be more like 10'.

    ok, so i looked back at my notes to get a feel for how much work remains to get process machines into a deployable state and although the software looks pretty complete, there is still a ton of USB interface and the firmware for the hardware interface kit... not to mention having to build some additional hardware... so:

    im going to recommend we build a dedicated heater control with one of these

    ok. I recommend getting three of these http://www.ebay.com/itm/NEW-Solid-State-Relay-SSR-40DA-40A-250V-3-32VDC-/121340070783?pt=LH_DefaultDomain_0&hash=item1c406e8b7f

    three because it's good to have a spare just in case, and i recommend switching both hot leads instead of just one. yes, you *could* just switch one lead. but that's how mine is set up and in my experience the leakage current through the devices goes way up when they are hot and it may not shut off all the way.

    you;ll need an aluminum enclosure to mount the SSRs in - i recommend something finned so its better at dissipating the heat.

    you'll need something to provide DC power for the SSR controls, a 12-20V wall wart will work.

    at that point we have most of the big stuff. you'll need to decide if you want to make the aluminum box big enough to hold the PID unit or if you would rather have it mounted separately. Then we can figure out the wiring.

    I'm trying to lay this out in my head.... Dryer outlet - cable - enclosure with SSRs and PID - Element power cable - Element (with small waterproof enclosure at the vessel)

    Or I could get this and toss in two extra SSRs. Replace the potentiometer with a PID.

    That amp enclosure is pretty sweet. Overkill, but sweet.

    That other kit could work, but im not sure about the control input on the ssr, so you'd need to get the specs to determine how to dive it.

    Sorry to confuse. The vessel has one port in it currently that has a failure in the weld on the inside so it won't hold suction. I'm going to drill that one out and replace it with the element. Then put a new bulkhead in for a diptube. Sooooooooooooooooooooooooo, diptube or bottom drain? Bottom drain is swanky, but normal bulkhead is easy.

    ohh.. well if you are going to install one or the other, i would do a bottom drain if you have a means for supporting the hlt that wont interfere with the bottom drain. it's actually easier to weld the fitting on the bottom.

    Positioning is an issue. If this was going on/into a "rig" maybe... But I'm just not sure about future applications, so I think the side wall is safer.

    are you welding it yourself or do you have someone doing the welding for you? and if it's someone else are you paying them?

    i ask because what im about to suggest would be uber cool but expensive if you are paying someone to do the welding for you...

    Somewhere in the middle. I don't have the equipment or the skill to weld stainless, no less food grade. I do have someone that works for me occasionally and likes to "trade" that is vurry good at it.

    I don't know a lot about this. But I had a friend build one of these and he ended up buying the larger heating elements. The first set he bought were I guess kind of standard and just didn't heat up fast enough or hot enough.

    Now I need to figure out the enclosure. Should I keep the temp controller and SSRs in a separate enclosure or put it all in one on the side of the kettle? Advantage: simple. Disadvantage: need to make triple sure no water can leak from the kettle into the enclosure.

    The ssrs will generate quite a bit of heat so id mount them separately in a metal enclosure. The pid should be somewhere convenient and can be in a nice sealed plastic box

    Those are what I was using when I was monkeying with a similar project. They work. The ultra low density elements are what you need to avoid having caramelized elements.

    since it's going into a MLT the carmelization issue shouldnt be a concern. but if you can fit the physically larger element into the tun without any issues then go for it.

    so the last thing we need is a small power supply for the SSR driver circuits. they can be driven off of anything from 3 to 32 volts. so basically anything will work. hell if you dont mind changing batteries each brew day you could use a 9V battery to drive them.

    I have plenty of old (and a few new/unused) power supplies. The first one that comes to mind is the one for the fence systems. I think they're 18v.

    K. 18v is between 3 and 32 so we should be good. Oh it needs to be DC... it that DC? If not we can rectify that situation.

    Schematic seems easy enough to follow. What's the downside to putting all of these in one box on the side of the tun? Heat? With a medium sized heat sink on each SSR is that still a concern?

    Schematic seems easy enough to follow. What's the downside to putting all of these in one box on the side of the tun? Heat? With a medium sized heat sink on each SSR is that still a concern?



    No real downside. Just placement of a bigger box up higher and a limited heat sink for the ssrs.

    Btw you gotta make sure you get the heat out of the box. A big heat sink inside the box wont do any good after about 30 minutes when the box turns into an oven.

    I hope that was already obvious...

    Ha! Yes it was obvious. But it may not be to some. I need to find a box. But first I need to figure out what size of box.

    Aluminum box on an aluminum plate. Works pretty good

    Are the controls and switch enclosures plastic or aluminium?

    The large control box and the switch enclosure are both water-tight plastic centex electrical boxes. I prefer to be "not dead". No amount of grounding can give you 100% confidence when dealing with high voltage in a wet environment...

    In a situation when the better ground path is both ground paths I hope to not be the second one.
