The EFMA floor heating system can be used for two purposes maximizing comfort.
Used as a secondary heat source (floor warming), it can help keep floor temperature

comfortable year round. Used as a primary room heat source (radiant floor heating),

it provides uniform, comfortable, and enveloping warmth. For the latter use, it is

important to follow the specific recommendations outlined below.
In light of environmental factors beyond REZNOR’s control—including thermal

insulation, heated area, floor covering emissivity, heat loss, and more—we cannot

guarantee that the EFMA system will provide a completely uniform surface temper-

ature in all cases, no matter how careful the installation. Consequently, REZNOR

cannot be held liable for any discomfort (e.g., a cold area on the floor) caused by site-

specific deficiencies.REZNOR liability is limited to the performance of its products.

3.1 Floor Warming

This type of heating is designed to enhance comfort and/or supplement the room’s

main heat source. It helps keep the floor at a pleasant temperature at all times.
Installing this type of system is very easy: simply unroll the EFMA adhesive floor

heating system directly on the floor, embed the heating cable in cement or an equiv-

alent binder (cement glue, ceramic glue, self-levelling cement) and install the floor

covering. Use the floor coverings listed in Section 3.3 and connect the EFMA system

to an appropriate thermostat, described in Section 5.

3.2 Radiant Floor Heating

EFMA can be used as the room’s primary heat source. It can heat the room using the

EFMA system only. Proceed as follows:
• Connect the system to an ambient temperature regulator;
• Calculate heat loss to ensure the system has enough power to heat the room;
• Sufficient insulation under the subfloor is very important. This insulation is to be

sure that the heat will rise into the room to be heated.

• Make sure to have a floor covering that meets the specifications listed in Table 3.3.
