Small aluminum joist plates are included to protect the joists where the Hott-Wire cable crosses over them during installation. Because Hott-Wire is a line-voltage cable, direct contact with the wood joist at crossing points needs to be avoided — the joist plates sit between the cable and the joist surface at those points, protecting the wood and maintaining a safe installation. They are part of the complete system package.
Decks over a heated living space or roof present a secondary concern — meltwater from the deck can run down onto the roof beneath and refreeze, forming ice dams at the roof edge. Installing a roof deicing system on the roof below the deck — ZMesh for non-metal roofing or Tuff Cable in Invizimelt for metal roofing — ensures meltwater has a complete path off the building without backing up under the roof edge.
For decks adjacent to gutters or downspouts, pairing the deck pan system with GutterMelt keeps the full drainage path clear — meltwater from the heated deck needs to flow freely through gutters and downspouts to the ground. GutterMelt is recommended wherever deck meltwater drains into a gutter system.
Yes, There are a few secondary options are available for specific deck constructions. For decks with a concrete or mortar substrate — where embedding cable is feasible — Tuff Cable can be embedded directly in the substrate for even heat distribution. For decks with non-conductive wood or composite decking on traditional framing where no heatsink or pan system can be fitted, ZMesh or Invizimelt can be laid on a solid sub-deck beneath the decking. Both are secondary solutions; the deck pan system with Hott-Wire is Heatizon’s recommended and most complete deck deicing approach for wood-framed joist construction.
Yes. The deck pan system — pans, Hott-Wire cable, relay panel, and activator — contains no moving parts. No moving parts means no wear components, no scheduled mechanical maintenance, and no service requirements beyond verifying activation at the start of each winter season.
The system activates automatically via a snow and ice detection sensor that triggers heating when temperature drops below threshold and moisture is present — no manual switching required. A relay panel allows a single activation device to control multiple heating circuits across larger deck surfaces simultaneously.
The deck pan heating system supports 120V, 208V, 240V, and 277V supply voltages — compatible with most residential and commercial electrical configurations without requiring a transformer. Voltage is specified at the time of system design based on the project’s electrical supply.
Heavy-duty aluminum tape is applied over the Hott-Wire cable after it is routed into the pan channels. Aluminum’s high thermal conductivity spreads heat rapidly and evenly across the full pan surface, directing it upward through the deck surface above. Without the tape, heat would concentrate at the cable rather than distributing across the pan, reducing melting efficiency significantly. The aluminum tape is what makes the pan system an effective heatsink in addition to a simple cable holder.
The deck pan system uses Hott-Wire MI (mineral-insulated) fixed-length cable — a central copper conductor surrounded by fiberglass insulation inside a copper outer tube and HDPE jacket, with cold leads factory pre-connected at both ends. The MI variant’s construction withstands the mechanical loads of deck installation and delivers consistent, reliable heat output over the life of the installation. Factory pre-connected cold leads eliminate field splicing during installation.
Every Heatizon deck pan heating system includes Hott-Wire heating cable, insulated aluminum heating pans, joist plates, heavy-duty aluminum tape, a relay panel, and an automatic snow and ice detection activator. Each system is custom-configured to the project’s dimensions, joist spacing, voltage, and decking material.
