Hot Liquor Tank (HLT) temperature control with an STC-1000 Temperature controller from Ebay.
Temp controller in place from the rear:
Case internals so far, thought I’d include an Earthing block (which I didn’t use, though I might earth the Pipework on the HLT sometime):
Temp sensor fitted to side of HLT http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=0461159 :
Controller fitted to case front with approx positions of the Heating & Cooling Sockets:
This box will be on the wall next to the HLT and wired from a fused Spur, When I get a fermentation fridge I’ll just get an extension lead and plug it in, though I may have to figure out a switchable Temp sensor to I can swap between two… though I suppose I could just buy a second Temp controller (*a couple of small 2-pin plugs & sockets would do this).
Holes cut and sockets in position:
I decided, seeing as I have plenty of case depth, I’d use the full pattress boxes to secure the socket fronts:
The Wiring:
Live Feeds to in series:
- -Temp Controller
- -Heating Relay
- -Cooling Relay
Switched Relay Feeds to:
- -3 Pin Live! on both sockets
To Neutral Feed in series:
- -Both 3 Pin Socket Neutrals
- -Temp controller
Wall Mounted and Wired into a Fused Spur:
The Inside, knot tied in sensor lead so I don’t go pulling it:
Heating LED on, heating up:
No LED indicator showing, Heating OFF, set to 81c with a 1c drop so it stays 80c or above:
🙂 I just need to finish painting the walls, Paint the floor, and complete my Brewery Stand!!
The Plastic box came from www.rselectricalsupplies.co.uk

The making of my Hot Liquor Tank (HLT), this is going to be the upper-most stage of my gravity-fed garage brewery, holding up-to 50 Litres with 2 heating elements, sight tube and ball-valve tap. This will eventually be Insulated and temperature controlled.
This first shot shows the first Element, a budget Kettle Element from Curry’s:
The Inside with element and other side of the Ball-Valve Tank connector with soldered-in copper pipe:
Both elements now fitted and doing a leak / heating up test:
The Polycarbonate sight glass tube fixed at the bottom with a Compression fitting and another Tank Connector, clipped on higher up with a 15mm Plastic pipe clip drilled and tapped out to screw onto a length of M10 Stainless studding (including nuts and washers):
I cut two holes in the lid, one for filling and another for sticking a spoon through to give it a stir. I decided I’d heat / Boil with the lid in place as it keeps the barrel’s shape better along with keeping the heat in, I shall eventually insulate the sides with Foil-backed Camping mats or something:
Element splash shrouds (and good for keeping fingers away) made from used Silicone Sealant tubes, I Just need to ‘seal’ them round with something.. maybe Silicone Sealant!:
The parts for this are as follows:
The Mango Chutney Barrels came from http://stores.shop.ebay.co.uk/Smiths-of-the-Forest-of-Dean-Ltd__W0QQ_armrsZ1 I bought 2 as I’m sure I’ll find a use for the other even if its just storing malt.
I got the Polycarbonate tube from – http://www.theonestopplasticsshop.co.uk I have about 1.5m left over which I suppose I could sell but might just hang onto for a while in case I find any other uses.
The little white Pipe clip and Tank connectors was from ebay.
The Stainless nuts, stud and washers came from – http://www.a2stainless.co.uk
The Compression Elbow was from – http://www.tradingdepot.co.uk as it seemed to be the cheapest place.
🙂 I Just had to bend a little bit of copper pipe to join from the Tank connector to the Elbow 🙂
Copper pipe from the Local Plumbers merchants.
Temperature Controller on order from Hong Kong, so I can control 1 element and keep the liquor at a constant 80°C ideal for Mash & Sparge:
I got a couple of long ‘Hot Condition’ Kettle leads and a Temp Sensor from RS:
461-159 NTCH Liquid Probe. SS. Silicon Cable
406-219 Hot condition straight plug w/cordset,2m
