FAQ Category: Snow Melting & Heated Surfaces

How long has Hott-Wire been in use?


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.

What are the operational costs of your snow melting systems?


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

Are your snow melting systems manually or automatically activated?


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

In what types of surfaces can your systems be installed?


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.

How long is the Hott-Wire warranty?


Hott-Wire comes with an industry leading, 10-year manufacturer’s warranty. Hott-Wire is ETL Listed for snow and ice melting applications.

What are the power requirements for your snow melting systems?


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

What is Hott-Wire?


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

How long is the Tuff Cable warranty?


Tuff Cable comes with an industry leading, 25-year manufacturer’s warranty. Tuff Cable is ETL Listed for snow and ice melting on surfaces and roofs and for interior floor heating applications.

Are your snow melting systems manually or automatically activated?


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.
