Sketch the System Layout
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 15 amps or more, additional branch circuits may be used, each having its own
overcurrent protection. These branch circuits may all be controlled
by a single thermostat if it is used with a system of electric relays
or power modules. The National Electrical Code specifies that each
branch circuit used in conjunction with a heating system must be for
the exclusive use of the heating system. Do not connect lights, outlets,
etc. to any branch circuit used with Peel & Stick Radiant Heat Film.
Thermostat Requirements
Locating the Thermostat
Thermostats are usually located near the power leads. However, they can be located almost anywhere, because
the power leads and the sensor wire can be routed to electrical junction boxes and extended to a location outside
the heated room (such as a utility room or basement). Location of the thermostat should be approximately 60”
(152 cm) above the floor on an inside wall, near the center of the room to allow the connection leads to reach. A
3” deep box is recommended for the thermostat.
Heat Loss Calculations
For installations where Peel & Stick Radiant Heat Film is
the primary heat source, a heat loss calculation must be
performed. For additional help, a heat loss calculator
can be performed by a heating & ventalation specialist.
The building professional must determine if the output of
product is enough heat to match the heat loss of the struc-
ture. Make sure that all sources of heat loss (transmission,
infiltration and radiant) are taken into account.
A separate heat loss calculation must be done for each en-
closed area (room, etc.). A separate control device must be
included for each enclosed area. Include a recovery factor of at least 20% more than the minimum calculated heat
requirement to cover unforeseen circumstances.
Some heat loss methods, particularly those designed for gas or oil based systems, provide their answers in BTU’s
Per Hour. To convert BTU’s Per hour to WATTS, multiply each area’s total amount of BTU’s by 0.293.
All wiring, fuses and/or circuit breakers must conform to National Electrical Code requirements.
NOTE:
The installation of this heating
product and listed components
shall be in accordance with
Article 424, of the National Electric
Code, ANSI/NFPA 70. All electrical
connections should be made by a
licensed electrician.
NOTE:
The product must be installed
using a thermostat which is
approved by the manufacturer.
For a list of approved thermostat devices,
contact manufacturer.
USE OF ANY OTHER THERMOSTAT OR
CONTROL DEVICE WILL VOID THE
MANUFACTURER’S WARRANTY.
