THERMOSOFT
Frequently asked questions
Common questions about THERMOSOFT from 3G Electric.
What voltages are available in the THERMOSOFT under floor heating line?
THERMOSOFT mats in the 3G Electric catalog are offered in 120V AC and 240V AC versions. The voltage is fixed per model and is part of the MPN, so a 120V mat such as WW20-120 cannot be substituted for a 240V mat such as WW20-240 on the same circuit. Watt output scales with length and voltage: examples include 126 W at 7 ft (WW7-120, 120V), 180 W at 10 ft (WW10-240, 240V), 360 W at 20 ft (WW20-240, 240V), 540 W at 30 ft (WW30-120, 120V), and 1,080 W at 60 ft (WW60-240, 240V). Confirm the supply voltage and circuit capacity before ordering.
Which THERMOSOFT thermostats or controllers work with these heating mats?
The catalog pairs THERMOSOFT mats with specific controls by model number. The UWG4-4999 appears against several SKUs, including WW20-120, WW20-240, WW30-120, and WW60-240. The UDG-4999 is listed for WW7-120, the USG-4000 for 3010-240, and the ADG-4999 for WW10-240. Because the control is matched to the mat, replacement or new-installation orders should reference the mat's MPN and its listed control. On most THERMOSOFT SKUs the thermostat is not included and must be ordered separately.
What lead wire length comes with a THERMOSOFT heating mat?
Lead wire length varies by model. The shorter mats, including WW7-120, WW10-240, WW20-120, WW20-240, WW30-120, and WW60-240, ship with a 10 in lead wire. The 240V models 1510-240 and 3010-240 ship with a 20 in lead wire. Lead wire length affects where the mat can terminate relative to the wall box or floor box for the thermostat, so it should be checked against the planned control location before installation.
What floor types are THERMOSOFT electric heating systems intended for?
THERMOSOFT mats are described for radiant floor warming under tile, stone, and laminate finishes in residential and light commercial spaces. They are electric resistance mats, so they are installed beneath the finished floor surface and do not circulate water or air. The 18 in width on the shorter mat (WW7-120) and the longer runs up to 60 ft (WW60-240) allow coverage of small rooms through larger open areas, subject to the watt density and circuit capacity for the space.
How do I match a replacement THERMOSOFT mat to an existing installation?
Start with the existing mat's MPN or its voltage, watt output, and overall length, then confirm the control it was paired with. The catalog lists the compatible control per SKU — for example, WW20-240 with UWG4-4999 and 3010-240 with USG-4000. If the control is being retained, the replacement mat should be one listed for that control. If the control is also being replaced, select the mat and control as a matched pair. 3G Electric lists MPNs, voltage, wattage, dimensions, and lead-wire length per SKU to support this comparison.
Are THERMOSOFT heating mats supplied with a thermostat?
Most THERMOSOFT under floor heating SKUs in the 3G Electric catalog are supplied without a thermostat. The product data notes that the thermostat is not included and is sold separately, and each mat lists the control it is designed for, such as UDG-4999, USG-4000, UWG4-4999, or ADG-4999. Buyers should order the mat and the matching control together unless a compatible control is already on site.
