RADIANT HEAT FILM FOR UNDER SUBFLOOR INTRODUCTION AND OPERATION The QuietWarmth® Radiant Heat system is a retrofit heating system that is installed under the subfloor, between the joists, to provide either primary or supplementary heat. Completely unseen, under subfloor heating panel sets warm floor surfaces to about 85°F / 30°C for unparalleled comfort.
LIMITED WARRANTY MP GLOBAL PRODUCTS, LLC (THE “MANUFACTURER”) WARRANTS TO THE ORIGINAL PURCHASER (THE “OWNER”) THAT THIS RADIANT HEAT FILM FOR USE UNDER EXISTING FLOOR COVERING MATERIALS BETWEEN SUBFLOOR JOISTS IN AN ACCESSIBLE CRAWL SPACE OR BASEMENT (THE “PRODUCTS”) will be free of defects in workmanship and materials and will conform in all material respects to any written specification that the Manufacturer provided to that customer before the purchase.
SAFETY INFORMATION Throughout the manual you will see Cautions and Notes. These notices highlight conditions, procedures, or other information that require special attention to prevent damage to the mats, to your flooring, or possible injury. For a safe and functional installation of QuietWarmth® Radiant Heat, read and follow these important safety precautions. Failure to comply with these items may result in injury or damage to the mats.
SECTION 1. Design Criteria The QuietWarmth System is made up of 4 major components: the heating panels, the wiring, the control device and the building structure. These components work together to create a system that will provide comfortable, trouble-free heat. The selection and installation of each component is very important to the system’s overall safe operation.
Control Device Options The fuse or circuit breaker used must be rated for a maximum of 20 amperes (no greater than 15 amp load). If a lower rated fuse or circuit breaker is used, it must be rated at least 25% greater than the heating system load attached to it. If an area requires more than the 15 amperes allowed, additional branch circuits may be used, each having its own overcurrent protection.
Heating Panels A typical QuietWarmth heating panel set. The QuietWarmth System is available in three standard widths, and two standard voltages. The following table shows the maximum number of single panels that a thermostat can control for each width and voltage.
SECTION 2. Jobsite Preparation Before work can proceed, all plumbing and electrical wiring that will not be accessible after installation of the heating system must be completed. This may require coordinating with the electrical and/or plumbing contractor(s). Make sure that insulation has been installed in areas that will be inaccessible after installation of the heating system. This may require coordinating with the insulation contractor.
SECTION 3. Installation Install the control device box Install a junction box for the control device. If this device is a thermostat, the box should be located, unobstructed, on an insulated inside wall so that the device reads accurately. Prepare the heating panels Prepare all heating panels for each room at one time prior to starting installation. Test each mat with ohms meter for resistance readiness. Record the resistance readings in the included chart 1. Cut the panel(s) to length (if needed).
Attach heating panel sets to joists 1. Align a heating panel set with one of the joists to which it will be attached. Make reference to the layout made in Part 1 for heating panel locations. 2. Nail or staple the panel set in place, leaving at least 6 inches / 150 mm clearance to walls or partitions at the connector end for wiring and final assembly. Nail or staple as close to the perforated bending line as possible, keeping the edge of the panel set straight along the top edge of the joist.
Wiring the heating panel sets 1. Once mats are installed properly, recheck mat resistance using Ohm Meter to ensure that no damage occured. 2. Run all leads to a junction box. To make the appropriate connections, wire the heating panels in parallel.
Attach heating panel sets to joists When using a floor sensing thermostat, the floor sensor must be installed correctly to control the floor temperature appropriately. It is important to install the sensor where the panels are placed for optimal control. The following are recommended options for installing the sensor. Other equivalent methods may be used.
SECTION 4. Inspection/Testing/Completion Visual Inspection When visually checking the panels, look for any signs of damage, wear or scratching that might have occurred during installation. If any portions of a panel set appear damaged, replace the entire panel set. Electrical Test A resistance check across the supply leads using an accurate ohm meter must be made to detect defects to the system — record the resistance readings.

Complete the installation 1. Install control device and connect to electrical panel box. Install and wire the control device according to manufacturer’s instructions in the junction box added at the beginning of Part 3 — Installation. Now, depending upon your wire lead installation, run the lead wires from the individual mat(s) along the base of the wall and up to the junction box. Wire the heating mats to the control according to the manufacturer’s instructions using the 12/2 Romex wire. 2.
Complete the installation 5. Attach system warning labels in the locations noted. These labels are an integral part of this heating system and must be installed for the warranty to be in force. One of each type label is provided for each 16 meters of heating panels CW1007: Affix to the electrical panel box. In the space provided, record the numbers of all circuits to which floor heating panels are attached.
Documentation The System Checklist and Warranty Registration form records vital information about your QuietWarmthTM installation. Fill out all requested information on BOTH copies. One copy is returned to the manufacturer to register the installation, and the second copy is for the homeowner’s records. This manual must be attached to the service panel so that it is easily accessible to the homeowner and any repair technicians.
