FIELD: agriculture, in particular, general and local heating of animals and birds by radiant heaters. SUBSTANCE: apparatus has unit for setting temperature and radiation-convective heat-exchange from animal or bird infrared emitter during their different developmental stages in case of variation of air temperature in house, respiration calorimeter and unit for controlling convective-radiation heat-exchange level during different growth and developmental stages of animal or bird. In the process of detecting heat fluxes, obtained data is compared with variable parameters of animal or bird, which are set from outside. Change in temperature of water in respiration calorimeter corresponding to change in temperature of animal or bird model must agree with predetermined dependence. EFFECT: increased efficiency, provision for optimum energy supply and precise adjustment of required temperature mode in animal or bird habitat in accordance with existing standards. 5 dwg
