PURPOSE:To improve heat collecting efficiency, by irradiating convergent light to a heat collecting pipe directly. CONSTITUTION:A transparent light collecting body S1 provided with a swollen out part E converging incident sunlight L is provided on a solar heat water warmer and convergent light (l) is made to irradiate to a heat collection pipe B. Heat collection effect can be improved as the convergent light (l) of the incident sunlight L is irradiated directly to the heat collection pipe B through the light collecting body S1 due to such constitution of a titled device. |
