RetroHeat Installation - Project Preparation

Radiant heated floors are only as good as their installation. Therefore, it is imperative to install the floor heating system correctly and have a licensed, qualified electrician wire the system. Before installing the RetroHeat floor heating panels, you must first do the following:

Complete all the plumbing and electrical wiring in the area to be heated. This area will not be accessible after the installation of the RetroHeat® film floor heating system, so it is vital to have all this completed prior to installing any of the floor heating elements.

Determine the number and type of floor heating panels that will be needed. (Refer to the elements in the Design Criteria section.)

Energy efficient, maintenance free, and easy to use, the Warmzone RetroHeat radiant floor heating system is an affordable system for heating your home's existing floors. For specific installation instructions, please refer to the product's installation manual.

RetroHeat Floor Heating System Features

RetroHeat floor heating element installed between floor joists

Measure the length of the floor joist bays underneath the areas to be heated to calculate the proper number of needed panels. Heating panels should not be installed under permanent fixtures such as bathtubs, showers, sinks, and cabinets. Extra floor heating panels should be on hand to account for any errors in cutting, job-site damage, etc.

System Components

Heating Panels - RetroHeat film floor heating panels are manufactured in large rolls. RetroHeat film floor heating panels are shipped in a roll that can be cut to length in the field. The panels can be cut in approximately 12” increments (at marked locations) to fit the length of the joist bay under the heatable area. Each panel is either 13-, 17-, or 25-inches wide and is designed to fit 12-, 16-, and 24-inch wide floor joists respectively. The panel features ½-inch flaps on each side that can be stapled to the sides of the floor joists.

Electrical Connector - Solder-less Tyco/AMP Termi-foil electrical crimp connector.

Electrical Insulators - Clear plastic snap-type insulator.

RetroHeat under floor joist heating elementThermostat - Warmzone RetroHeat systems are controlled by a thermostat with a built-in GFCI and in-floor sensor. This programmable thermostat has a built-in clock function that allows you to set several events per day, including weekday and weekend settings. The temperature can also be temporarily changed for a single event. Afterwards, it will return to the program schedule on the next scheduled event.

RetroHeat Floor Heating System Installation - Tools and Materials

Crimping Tool - Used to attach electrical connectors to the heating panels and wires to the connectors.

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 completed.

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 194°F (90°C).

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-inch or 3/8-inch (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.

Recessed Fixtures - At least 2 inches of clearance must be maintained between the trim of recessed fixtures or outlets and the heating panels.

Heat Sources - At least 8 inches of clearance must be maintained between heat sources and the heating panels.
