Floor & Space Heating
General Heatizon Product Questions
All of our systems come with complete installation manuals and can be installed by any electrician, contractor, or experienced “do-it-yourselfer.” An electrician is needed to supply the necessary power and to Control Unit location. We also offer installation DVD clips for an installation reference. Heatizon offers unlimited technical support to customers.
I have a new home and my driveway concrete is structurally sound. I’d like to do a retrofit Tuff Cable installation. Can I resurface the driveway after installation to make it more aesthetically pleasing?
Line voltage products like Heatizon lines of MI Cables, Heatwave floor warming mats, and Self Regulating Cables are fed by a typical 120V, 208V, 240V, 277V, 480V and in some cases for MI Cables up to 600V AC power. These products are either constant wattage single conductor or dual conductor or dual conductor self regulating. High voltage products do not require a transformer and are an economical solution for many projects. Typical high voltage products offer a lower warranty than low voltage products and more expensive circuit breaker components for outdoor applications than low voltage systems. Low voltage products use a step down transformer to convert high voltage to low voltage. These systems are very easy to repair compared to high voltage products while using a safe low voltage power source. Low voltage systems offer a higher warranty than their line voltage counterparts. Heatizon offers such a wide range of product choices because each and every one has an application where they fit best offering our customers a choice for the best product to fit their budget and application.
Roof Deicing & Heat Tracing
GutterMelt SR Cables are self regulating and do not over heat. The heat output of these cables increase as the surrounding temperature decreases and output decreases as surrounding temperatures increase. GutterMelt is perfectly fine to use with plastic downspouts due to these self regulating heating characteristics.
Our gutter heating cables (GutterMelt) are the ideal solutions for preventing dangerous and damaging snow and ice forming. It is recommended that gutter melting cables be used in conjunction with our roof systems. Our cable systems are also activated by automatic sensors that sit in the gutter. And conserve energy by only turning on when necessary.
The Tuff Cable Invizimelt/Heat Sink kits for roof deicing are designed to be installed under metal roof, valley metal and flashing. Tuff Cable must always be embedded completely in an Invizimelt/Heat Sink system regardless of which roof covering is going over it.
Roof deicing systems can be activated with an aerial-mounted moisture and temperature sensor, temperature sensor, gutter –mounted switch, or 12 hour manual timer. With the aerial-mounted moisture and temperature sensor with automatically turn on when the temperature is below 38 degrees and there is moisture on the sensor.
9” ZMesh is sandwiched in between two layers of ice and water shield and stapled to the roof decking. Shingles are then secured with nails directly on top. Nails can pierce the ZMesh as long as the nails do not come in contact with any other metal objects. The ZMesh comes in 9” wide rolls and is rolled out over the area to be heated. Heating at least 6” above the roof eaves is recommended.
ZMesh is installed under shingles for several reasons. Heatizon offers a long term solution to winter roof problems and we believe in do the project once and do it right. ZMesh is protected when it is installed under the shingles and in most cases will outlast the roofing above. Thinking long term we offer an invisible solution as well as the longevity of a system that will perform for the long term so the customer will never have to worry again about winter roof problems. To install ZMesh existing shingles will need to be removed by a roofing contractor so it can be installed on the sub-roof with a layer of ice and water shield over the top of the system before shingles are installed back over it.
Can ZMesh be installed on an existing TPO membrane roof system and then covered with another layer of TPO material?
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.
