Mangrove Jack's Heater Belt 220-240V. (25W) A heater belt is designed to be secured around your fermenter to help keep it at the right temperature during fermentation. It is possible to regulate the heating of the liquid by adjusting the height of the belt around the fermenter. 

The STC-1000 is a temperature controller you can use to control your fermentation temperature. It has a hot and a cool circuit which you can use to heat and ferment your wort depending on the setting of your controller. This is a bare bones controller, and you need to assemble the controller yourself.

The easiest way to do this is to buy two cheap extension leads which you can use for all wiring and plugs/sockets, and then assemble into any suitable housing such as a Systema box.

There are lots of easy to follow wiring videos available on Youtube.

Comes with a 1 meter long temperature probe.

Model -240V

A Heat Pad to help keep your home brew warm. Also called a heat panel. 


This is a quality, New Zealand made product.

This temperature connects with the RAPT web portal meaning that you can monitor, log and control the devices plugged into this temperature controller box remotely.

This 30w Heating belt will gently warm without creating major hot spots on your fermenter. 
One reason to go belts over pads for the simplicity of adjusting the height of the belt on your fermenter to increase or decrease the heat transfer. With a pad, you're unable to do this, and may potentially cook your yeast turning your hard work into a giant bandaid.

We highly recommend using a belt with a temperature controller for precise temperature control. If you're fermenting in a fridge, you can also use the controller's cooling function as well to control both the belt and the fridge.
