FIELD: construction.
SUBSTANCE: invention relates to devices for prevention of ice formation on edges of roofs. Device comprises a heating tubular element with air holes fixed along the roof and roof edges heating contact and located on their sections along the perimeter with formation of closed circuits, which is higher through distribution units is also connected to a working sinusoidal closed heating tubular element. One of the distribution units is connected to a vertical tubular pipeline supplying a hot heat carrier. Hot air is supplied due to application of fan heater, housing of which is equipped at outlet with cone-shaped closed transition section connected to vertical pipeline of heat carrier and control device. System of arrangement of risers of direct pipeline and return pipeline is located in basement and connected to system of heating pipelines of building, as well as connections of circulation pump and control system.
EFFECT: increased operational reliability of the device.
