They break down proteins to generate energy, and do not produce much heat. They also produce some very smelly byproducts that can make a compost pile stink like rotten eggs or sour milk. These smells often attract scavengers. Compost that contains meat can attract mice, skunks, buzzards, and even bears.
The power conditioner provides protection against surges in power just as a surge protector does, but a power conditioner also maintains a continuous voltage fed to the computer during temporary voltage reductions, such as a brownout.
A heater coil is a device used to heat water or air. Typically electric, the heater coil acts like a large resistor, and as the electric current flows through it, it begins to heat up. The resistance wire used in common household toasters is the same type of wire used in a heater coil. The amount of heat produced by the heater coil is controlled by a rheostat switch. Many appliances, such as hot water heaters, electric clothes dryers and electric ovens, all use some type of heater coil to produce heat.
