Advantages of roofs, gutters, and downpipes heating


Older buildings are obvious victims of ice and snow, capable of destroying fronts, roofs, drainpipes, and roof gutters. Old roofs are often poorly insulated or based on insufficient construction standards; these aspects enable water to enter the building. When the winter frost sets in, damage is inevitable. 

DEVI provides a high-tech heating solution to efficiently fight against ice and snow. DEVI ice and snow melting system for roofs consists of heating cables, an electronic thermostat, and installation accessories. DEVI ice and snow melting solutions for roofs can be installed in any type of roof construction.

The wide range of DEVI products provide the possibility to apply the system on metal, bitumen, graveled, or tile roofs. Depending on the requirements, the DEVI system can be applied on the roof edge, drain pipes, roof gutters and valleys.

Sound investment

An ice and snow melting system from DEVI is an investment in comfort and safety, alleviating concerns about sudden building damage as well as driver and pedestrian safety. In addition, the heating system is a financially sound investment as roofs, drainpipes, and roof gutters are always expensive to renovate after a harsh winter. As the cost of an ice and snow melting system correspond more or less to the renovation expenses of one winter season, a fast return on investment is guaranteed.

Product choice for heating roofs, gutters, and downpipes:

The choice of cable, thermostat, and sensor depends to some extent on the size, type and construction of the roof and to the requirements of the installation. Basically, we recommend the use of a DEVIsnow™ 30T or DEVIiceguard™ 18T.

When it comes to thermostats, we recommend DEVIreg™ 316 with an outdoor sensor for minor roof and gutter systems; whereas for larger roof and gutter systems, we recommend a DEVIreg™ 850, which consists of a combined moisture and temperature sensor.

The sensor types used for roofs and roof gutters are outdoor temperature sensors, moisture sensors for roof gutters, and wire sensors, all depending on the type of installation.

DEVIsafe™ is an extremely high-quality, 360° fully screened twin conductor cable with a tough outer sheath (UV stable). Its round profile and robust construction ensures a fast, simple and safe installation in multiple outdoor applications. The cold lead is an installation cable with solid conductors ensuring fast installation with a clearly visible connection. To ensure a long life-time, all cables are minutely inspected including tests for Ohmic resistance, high voltage and material controls to ensure the quality. This means that we are proud to supply our extended DEVIwarranty™.
The DEVIiceguard™ is a self-limiting parallel heating cable that is used for ice and snow melting on roofs and in gutters and downpipes. The self-limiting capability of the cable ensures that the output of the cable increase or decrease according to ambient temperature. The heating cable is flexible and easy to install as it can be cut to length at site and installed directly on to the roof and gutter system.
The DEVIpipeheat™ w/plug is a self-limiting heating cable that is mainly used for frost protection of pipes. The self-limiting capability of the cable ensures that the output of the cable increase or decrease according to ambient temperature. The heating cables can be installed on to the pipe system or inside the pipe. The DEVIpipeheat™ w/plug comes with an EU Schuko mains plug.
The DEVIreg™ 850 is an advanced thermostat with LED display used for outdoor ground or roof applications. The sensors provide information about both moisture level and temperature, resulting in an optimal control of the heating system. The system can be set up in three ways; as a single system for roof or ground (1 to 4 sensors), as a dual system for roof or ground (2 - 4 sensors) or as a combination system for roof and ground (2 - 4 sensors). In the dual / combination systems it is possible to prioritize between the zones, e.g. if only a limited power output is available.
DEVImulti™ HDPE is a high-quality, 4-conductor cable with a tough outer sheath made of polyethylene (HDPE) designed for frost protection of long pipes. DEVImulti™ HDPE is constructed of 4 identically conductors. The conductors can be connected in different ways meaning that the same cable can provide up to 11 different outputs, depending on the connection made. The cable is very rigid and therefore perfectly suited for internal installation in pipes, it can be supplied in 2 versions with different Ohmic values. Polyethylene is approved for use with foodstuffs.
