The temperature of the biogas production process is quite critical. [[Methane]] producing bacteria operate most efficiently at temperatures between 95°F and 100°F (or about 35°C). In colder climates heat may have to be added to the chamber to encourage the bacteria to carry out their function. In places where the temperature drops below 5°C (40°F) in winter, about 20% of the gas generated will be needed for heating the digestor and maintaining the digesting material. As such, proper insulation is needed. | The temperature of the biogas production process is quite critical.

The insulation would need to be applied entirely around the tank | The insulation would need to be applied entirely around the tank aswell as below it (between the tank and the ground). This, as the temperature of the ground several feet below the surface remains relatively constant at 50°F – 55°F, hence acting as a heat sink deriving warmth from the tank. It is possible to dig the tank into the ground (to reduce cooling from the wind), yet it is best to keep a space open between the soil and the tank itself. | ||
