A heated belt to raise the temperature of your home brew above the ambient room temperature. The belt is designed to fit around a 25 litre fermentation vessel, but will also fit around two demijohns. Please note that this belt is not thermostatically controlled, so for accurate temperature control, should be used with a digital temperature controller. Without a temperature controller, the heating can be controlled by changing the belt's position; for more heating, move near the bottom of the container. For less heating, move towards the upper liquid level.
