Self-regulating heated drains and gargoyles

It works on the principle of changing the resistance between semiconductors depending on the ambient temperature. In layman's terms, the lower the temperature around the drain, the greater the heating power. The greatest risk of fouling gullies or gargoyles is at temperatures around zero, when the so-called ice plug from ice and snow can impair the gullies and entire pipes. The heating is designed to protect not only the mouth of the roof drain, but also its immediate surroundings.

Advantages of self-regulating heating

• reliable drainage even in winter
• 230 V/50 Hz voltage — no need for transformer or controller
• possibility of connection to heating gutters, drains, garage entrances, etc.
• simple wiring via a switch or thermostat
• saving electric energy

Heating wiring and regulation

The self-regulating heating system increases its performance depending on the ambient temperature, but even in the summer months it has a minimum consumption of electricity. Therefore, it is recommended to turn off the electricity supply at temperatures above +3°C. Thermostats are recommended to be set to +3 °C and the temperature sensor should be placed on the north side or in another place without external influences.

Ways to engage

• Without the possibility of switching off (electricity consumption even in summer - not recommended)
• Mechanical switch (requires operator) or timing socket
• Outdoor thermostat with integrated temperature sensor
• Thermostat for junction box including temperature sensor for measuring outdoor temperature
• Thermostat for distribution box including temperature and humidity sensor
