Snow Melting & Heated Surfaces
MI Cables were first invented in 1896 and have been in use since the early 1900’s. These durable cables are a reliable system and Hott-Wire has been specially engineered for radiant heating being resistant to water absorption. The inert fiberglass reduces cable breakdown unlike Magnesium Oxide MI Cables. Hott-Wire has been sold worldwide.
The average operational cost for a snow melting system is approximately $0.18 per 100 square feet per hour. This figure is based on a system producing 22 watts/sq. ft. or 73.7 BTU’s/sq. ft. with a kwh rate of $0.08 per hour (the national average kwh is $0.08/hour). If you know the square feet of the area you wish to heat and your kwh rate, you can calculate the operational costs with this formula: heatable sq. ft. times watts/sq. ft., divided by 1000, times your kwh rate.
Hott-Wire systems can be activated with an aerial mounted moisture and temperature sensor, temperature sensor, pavement-mounted snow sensor, or 12 hour timer. The aerial and pavement mounted sensor will automatically turn on when the temperature is below 38 degrees and there is moisture on the sensor. Heatizon has its own engineered relay panel (M330) offering 30Amp or 50Amp relay switches for single activation of multiple circuits.
Hott-Wire heating cable is the perfect choice for snow melting in driveways, sidewalks and stairs. Hott-Wire systems can be installed in new pour concrete or asphalt, under tile or pavers in a sand bed, and can be retrofitted into existing concrete or asphalt.
The power requirements vary from system to system. Generally Hott-Wire heating systems require a 208, 240, or 277 volt supply 30 Amp breaker for smaller areas. For larger areas a double pole 40 Amp breaker is used. Systems are designed to ASHRAE standards and vary in size and load depending on region and application
Hott-Wire is a resistance Mineral Insulated heating cable that is very durable. Hott-Wire is a fixed length line voltage element consisting of a central single or dual conductor surrounded by fiberglass inert insulation compressed in a Copper tube, which is coated with an HDPE Jacket. Hott-Wire has been engineered to work as a line voltage system.
Tuff Cable systems can be activated with an aerial mounted moisture and temperature sensor, temperature sensor, pavement-mounted snow sensor, or 12 hour timer. The aerial and pavement mounted sensor will automatically turn on when the temperature is below 38 degrees and there is moisture on the sensor.
