Whilst there is no temperature gauge the belt can be moved up or down the fermentation vessel to control the temperature. To use an electric heat pad, you need to plug it into an electrical outlet and set the temperature to your desired level. The Heat Belt can be used to aid fermentation with one or two demijohns or any make of 5 Gallon/25 Litre vessel and is suitable for both beer, spirits and winemaking.

Moving the Brew Belt up the vessel will lower the temperature and lowering the Brew belt will increase the temperature. Please ensure your address details and contact details are correct as once Royal mail has issued charges we cannot get them refunded.I'm afraid my alternative to the kitchen would be my shed which gets way too cold even with a heater. If the item has been stolen from a secure location or by a neighbour this will need to be reported to the police. Heating the yeast directly for too long is probably not ideal so you may want to limit the length of time you use a heat pad to just a week to avoid putting too much stress on the mass of yeast. A brew belt may be insufficient in the cold winter months, the solution is easy, just cover the FV with a blanket.

Both types of device use very little energy and are suitable for both fermenting buckets or carboys and demijohns (although I would urge caution directly heating cold glass). Please do not worry about live cultures please see the guide below for how long they can be in their packaging. Some mention it's a quality product that works as required, while others say that the quality is poor and doesn't produce anywhere near enough heat. Heat belt heaters are adjustable and can be set to the desired temperature range for optimal fermentation for this you just move the heater up or down, Down for more heat, higher for less heat for your home brew. The heat belt heater will then provide a constant source of heat to maintain the desired temperature.attaching the Inkbird temperature probe to the fermenter with adhesive tape and covering it with a thin layer on insulation sheet, is already a nuisance, let alone covering available space on the fermenter with a heating belt (and how is the belt attached ?
