FIELD: heating.
SUBSTANCE: invention relates to heating systems, namely to electric heaters for double-glazed windows. For this purpose, hollow aluminium spacer frames are used for double-glazed windows and hollow spacer frames are arranged, arranged in a flat structure, their connection to each other along long or short sides on one of two opposite sides of the flat electric heater. Invention allows to use aluminium spacers to increase heat emission of electric heaters due to presence of channels for implementation of forced convection. This ensures durability, strength, resistance to external effects, ease of assembly, low cost of electric heating element, having high heat conductivity, resistant to external effects.
EFFECT: increased area of heat release of flat electric heaters and provision of possibility of creation of additional forced convection.
