120v 10 gallon Blichmann Boilcoil not really boiling

[Keola Thompson]

Hi All,

I my setup includes a 120v 10 gallon Blichmann Boilcoil. I've running it on a 20A outlet, I've tested the voltage and i'm getting 120V from it and to the Blichmann plug.
7 Gallons of 80 degree water gets to around 211-212 in 40-45 min, but then it stops. There's no vigorous boil like I was expecting. There's only bubbles coming up right by the coil, not really moving the water much.

I don't know what could be wrong. I've added insulation and even a bucket heater and its still not really boiling well.

Anyone got a fix? Thanks!!

Water boils at 212 under 1 atm pressure and at sea level. You're not going to see any higher temp than 212. Water boils for me anywhere from 200 to 202 depending on the season and weather conditions.

I'd say if you're hitting 212, you're not ever going to see any higher. Before moving to my current location, I lived in Death Valley, CA and was as close to or below sea level as you can get. Even on my hottest 127 degree day, water boiled at 212.

When water boils, it cant get any hotter. All you're doing at that point is making the boil more vigorous, which theres really no point of. You're extracting all the hop oils and driving off all the DMS that you can.

That coil is rated at 2250 Watts. With 7 Gal what you are seeing is expected. In fact, you seem to be outperforming the calculation on this site. Only you can say if you believe the boil is vigorous enough.

I use the same boil coil in my kettle and usually have somewhere between 7-8 gallons of wort at the start of the boil. I added a 120v induction plate to give it the extra ummph to reach a rolling boil. Works great and was not expensive.

You can also put Reflextix around your kettle to keep in more heat/energy, thus increasing the vigor of the boil.
