We have used these pads ourselves for over 20 years, and are very familiar with tall of them. When used flat and with various size brewing and fermenting containers on top of the heating mats they will raise the temperature about 5 - 10F degrees over the ambient room temperature. As a wrap-a-around the temperatures may be raised 10-25F degrees but is limited usually to a single container. (depending upon size)

If your room is 68F these heating pads generally will warm up the brewing containers to 73F - 78F. When you use the Wrap-a-Around method roughly 3 times the thermal effect can be achieved, though you are limited to the number of containers that may be warmed. For example a one-gallon glass jar may be warmed up 5-10 degrees when it is seated on the pad versus 15-30 degrees warmer when wrapped in the heating pad. Air flow and ventilation plays a role and one can move the wrap around pad slightly away from the container to manually adjust temperatures. - or use the Thermostat regulator just set-it and forget-it.

Note. The colder the room the less efficient. With higher ambient, room temperatures or with smaller containers, you can use coins to lift the container above the heating pads. Of course our Heating Regulator will automatically adjust temperatures to your optimum settings worry free. The more consistent the environment the more predictable and reliable will be your ferment and brew. To warm your ferment in cold environments (consistently below 65F) one can create a Brewing Cabinet. This is basically a "Box with two holes, one on the bottom" one on the top, to allow ventilation and to trap / control the warmer air inside the box. Trapped air is easier to heat and maintain via the holes at top and bottom. Open, allowing greater air flow for cooler, and closed for warmer. Set your ferment inside the box (or a 3 sided box on top), Remember air flow is critical to a kombucha ferment (aerobic ferment) not so critical in anaerobic or lacto-ferments or yeast ferments. see the FermenWrap Test on side panel.

Our square 12 x 12 25 Watt is the best for Oak Barrels. Oak is heavy and insulates very well. It takes a larger wattage in a smaller area, to deliver efficient heat. The Brew Belts are also 25 watts and a small concentrated area however they result in burn marks along the belt line. The best choice for warming Barrels or to build a Brew Box. (see above) is our 12 x 12 25 watt heating pad.
