Since SnowMeltz CANNOT be shortened, it is vital to choose the correct size system before installing. It is advisable to always get a smaller system for the area, for example: if the area is 48 square feet, choose a 40 or 45 square foot system.

Standard SnowMeltz kits include the SnowMeltz mat(s), an automatic activator, and jumpers. These kits are designed to use a single 20, 30 or 40 amp, 240 volt GFI breaker.
