DEVI heating systems can be installed on almost all types of roofs. They effectively remove accumulated snow and ice, ensure patency of gutters and prevent damage to the roof and facade caused by icing and uncontrolled water flow. Additionally, heating gutters and downpipes prevents them from being damaged by freezing water and ensures effective drainage of the roof surface. Heating cables should be installed along the edges of the roof and in places where accumulations of snow and ice are possible. The installed thermostats cooperate with external sensors, thanks to which the system can adjust its performance to current weather conditions. The power is turned on and off at selected times. Roof heating systems are installed primarily in gutters and on the outer parts of the roof covering, in internal gutters on multi-slope roofs and in vertical downpipes.
