Electric brewing question
« on: December 17, 2018, 03:54:34 PM »
Ssbrewtech is coming out with an electric  brewing system that I am very interested in converting to. (  probable Christmas present from wife 😁 ).   I was just wondering for those of you who brew with electric, what are the relative speeds that you can go from ground water temperature to say 170 for strike temperature? Or ground temperature to boiling?   I do 5 gallon batches.   Just wondering what I can expect as far as cutting down on brew day? Their element looks pretty strong — 5500 Watt Halo Heating Element.

Thanks
I am a great believer in luck, and I find the harder I work, the more I have of it.

I have the High Gravity 240v system (think its 4500 watts) BoilCoil and yesterday got 9 gallons ( brew 6 gallon batches) of 56 degree water to 158 mash in temperature in 26 minutes.  I haven't gone directly to boiling but after a mash out temp of 168, it only takes me 10-12 minutes to get to boiling.

 Awesome, thanks.  Just what I wanted to hear. That will definitely shorten my brew day. Anything too shorten brew day is good in my mind. I’m always so exhausted at the end.

I have a Spike System with 15-gallon vessels.  The HLT has a 5500-watt element, and will raise the temperature of 15 gallons of water around 2 degrees F per minute when at 100% output.  The real time savings for me is not having to babysit the HLT while it's heating up.  No more worrying about overshooting the target temperature, or having a strong gust or wind blow out a propane burner.  It's also nice to brew inside when it's really hot or really cold outside - and electric needs less ventilation than a gas system.

  • Great beer. Less work. More fun.

I was looking at the SS Brewtech electric systems myself but they are so slow to roll out the entire system that I bought a turnkey system from High Gravity instead. As much as I really like SS Brewtech products I couldn't be happier. AND I'm brewing already instead of waiting for the rollout of the next piece.

Assuming it's reasonably well insulated* and running at full power, a 5500 W element will heat water at 73°C/L-min (35°F/gal-min if I correctly converted into Freedom Units).

*I assumed 93% heat transfer efficiency since that's about what I see on my 10 gal HLT, which is just a stainless kettle wrapped in reflective duct insulation.

I use a 3500W Induction cooktop under my HLT/BK. I’ve never timed it but by the time I get the mill out, run the grain thru it, and put it away, get the scales and salts/minerals out, measure them, get the MLT set up and ready, the water is about ready for me.  I image the element would be about the same if not faster.

 Awesome, I just looked at his review and was very happy with it. Answered pretty much all of my questions.  Hope Santa is good to me this year.

I read the review, and while much of it seemed positive, the 1.5 F temperature variation during mashing seemed excessive. A properly-designed system should be able to achieve much better control than that. I can achieve 0.17 F standard deviation for a 60-minute mash, with 0.7 F max-min range.

There’s also this: Robobrew Brewzilla 65L/16.9G. $699.

Not for me though, I am a small batch guy. I love that my Grainfather does 2.5 and 5 gallon batches.

I was waiting for the Spike system as well.  In the meantime, I came across Ruby Street Brewing.  I purchased Fusion 25 and couldn't be happier.  Amazing quality and customer service.

I timed the cooktop under 9 gallons of water for today’s brew day. It took 45 min from room temp to 160* which gave me time to pour a cup of coffee, mill grain, weigh minerals and attach plumbing.
