Preparation | ![]() |
Before installing your RetroHeat system, all plumbing and electrical wiring that will not be accessible after installation of the heating system must be completed. The number and type of heating panels needed must be determined beforehand according to the elements in the Design Criteria section.
To calculate the proper number of needed panels, measure the length of the floor joist bays underneath the heatable areas. Heating panels should not be installed under permanent fixtures such as bathtubs, showers, sinks, and cabinets. Extra panels should be on hand to account for any errors in cutting, job-site damage, etc. |

Heating Panels - The RetroHeat heating panels are manufactured in large rolls. Each roll consists of separate 12"-long panels that are connected together. The panels are shipped as one roll to the customers. Customers then cut the roll into the appropriate length strips of panels to fit the different bays under the heatable area. Each panel is either 13", 17", or 25" wide and designed to fit 12", 16", and 24" wide floor joists respectively. The additional panel has 1/2" flaps on each side, which are stapled to the sides of the floor joists.
Electrical Connector - Solderless Tyco/AMP Termi-foil electrical crimp connector. Electrical Insulators - Clear plastic snap-type insulator. |
![]() Technical Specs:
Manuals - The installation and operating manuals list detailed information about the heating system. These manuals should remain with the home or building owner when the job is done. OTHER TOOLS & MATERIALS The following tools and materials are required but not supplied by Warmzone. Thermal Insulation - The insulation must be of the non-flammable type specified. The only types of insulation permitted with the RetroHeat system are un-faced, fiberglass, batt insulation and rigid insulation panels. Dielectric Tape - UL listed or CSA certified "electrical" tape rated for at least 90°C / 194°F. Ohmmeter or Multimeter - An accurate ohmmeter or multimeter must be used during the testing phase to ensure that the system is correctly installed. It is suggested that a digital meter is used rather than an analog (needle) type. Staple Gun - Used to attach RetroHeat panels to ceiling joists. Recommended staple length: 5/16" or 3/8" / 8 or 9.5 mm. Assorted Hand Tools - Conventional electrical wiring hand tools, knife and/or scissors for cutting heating panel sets from the supplied roll. |
