HEAT-INSULATING PANEL ASSEMBLY WITH TWO HOT WATER PASSAGES Russian patent published in 2013 - IPC F24D3/12 

FIELD: heating.

SUBSTANCE: heat-insulating panel assembly includes the following: a variety of panels; the first and the second hot water supply tubes installed separately inside the panel to provide at least two hot water passages; and the first and the second connection assemblies provided in the panel for connection to a boiler or to the first and the second hot water supply tube for water circulation in the first and the second hot water supply tubes. According to the present invention, two hot water tubes provide different hot water passages inside the panel used for heating of a room.

EFFECT: improving heating efficiency; simplifying manufacture of a double structure of hot water supply tubes with improved stability to temperature variations and corrosion; possibility of choosing a configuration, a pitch and a shape of tubes without any restrictions owing to using as a tube material the thermoplastic elastomer with a polybutylene layer on inner surface, as wells reducing the diameter and length of hot water supply tubes installed in the panel, due to which thickness of the panel is reduced and the boiler load is minimised.
