The invention discloses a solar infrared heating system. The solar infrared heating system comprises a solar hot water loop composed of an all-weather solar water heater, a heat storage pool, a water heater solenoid valve, a water heater throttle, a pool pump, an auxiliary heat pump, an auxiliary throttle, a pipe network, a pipe network pump, a pipe network solenoid valve, a pipe network throttle, a hot water throttle, an oxygen generator, a tap water throttle and the like, an auxiliary hot water loop and a heating loop. According to the solar infrared heating system, hot water supply and heating are performed by the all-weather solar water heater, the auxiliary heat pump is started only in long rain and snow weather, heating and heat storage are performed in the maximum temperature period in the day, and the efficiency is improved; load shifting can be performed and electric change is saved; oxygen can be generated and the humidity is adjustable; the optical scheme can be selected according to weather conditions, geographical positions, user requirements and the like to save energy substantially; heat exchange links and costs are reduced due to a water cycle heat storage and supply system; the solar heat conversion efficiency and the air heat conversion energy efficiency are high; and the heating system is comfortable, energy-saving and efficient.
