Self-regulating heated outlets and gutter spouts

It functions in principle of resistance change between semiconductors in dependence on ambient temperature. Laically said, the lower temperature in outlet surroundings, the higher output the heating has. The highest risk of outlets or gutter spouts blocking is with temperatures around zero when so called ice plug of hoar-frost and snow may block outlets or even whole piping. Heating is designed to protect not only a mouth of the roof outlet but its immediate surroundings as well.

Advantages of self-regulating heating

• Reliable drainage also in winter season
• Voltage 230 V / 50 Hz – without necessity of a transformer or a control unit
• Option of connection to heating of gutters, downpipes, garage entries etc.
• Simple connection via a switch or a thermostat
• Electric energy saving

‍

Heating connection and regulation

The self-regulating heating system increases its output according to the ambient temperature but in summer months it has a minimum electric input. Therefore we recommend to switch off the electricity supply when temperatures exceed +3 °C. We recommend setting the thermostats to +3 °C and placing the temperature sensor to the northern side or to another side without external influences.

Basic options of connecting of heated outlets

• Without possibility of switching off (energy consumption also in summer season – not recommended)
• Mechanical switch (manipulation required), or time socket
• Outer thermostat with integrated thermal sensor
• Thermostat to a switchboard including thermal sensor for measuring of outer temperature
• Thermostat to a switchboard including thermal and humidity sensor
