25 Watts. Heat pad is currently white in colour. Flat polycarbonate heat pad, place fermenter directly on top of pad. Ensure pad is on a flat heat safe surface.
Suitable for various sized fermenters, glass or plastic.
Heat pads give out more heat than heat belts as heat radiates up through the brew with less heat loss to the atmosphere
Turn the appliance on when the brew is dropping below your desired temperature range and turn it off if heat is getting too much.
More suitable for use with spirit washes and cold locations in NZ. Best used in conjunction with a stick on thermometer strip (sold separately).
