Single-valuedness conditions for differential equation solution thermal conduction are formulated. Heat treatment is realized in heliokamera working according to the «hot box» principle. The scheme, constructional peculiarities and technological preferences of heliotechnical devices as the «hot box» are given.solar camerabetonsolar energyгелиокамерыбетонсолнечная энергия
