TOPWET, a European manufacturer of roofing systems, presents a heated version of its Flat Roof Drainage Systems

The heating system uses a 5-foot self-regulating NM-B 14-2 connection cable under the waterproofing membrane around the inlet perimeter. It operates at 110V, 60Hz, and doesn't require a transformer for connection.

Electric heating systems for drains use semiconductor resistance to adjust heat output based on surrounding temperatures, preventing ice blockages in winter. They protect drain outlets and immediate surroundings from ice accumulation at around 32°F.

TOPWET manufactures heated versions for roofs, terraces, renovation, balconies, and through-wall parapet drains.

When is it appropriate to use heated drains?

  • For buildings at higher elevations and in areas with significant snowfall
  • In cases where the drain is exposed to the exterior
  • If there is no expectation of heat rising from the common sewer system

Advantages of Self-Regulating Heating:

  • Reliable drainage even in winter
  • Voltage 110 V / 60 Hz – no need for a transformer or control unit
  • It can be connected to gutter heating, drains, driveways, etc.
  • Simple connection using a switch or thermostat
  • Energy savings
