<p>A water heater that is activated by a change in the water temperature detected by a temperature sensor, the heater being formed by a cold water inlet tube; a hot water outlet tube; a heat collector; a tube coiled in the same direction as the heat collector having a first end portion and a second end portion, and jointed by the first end portion to the cold water inlet tube; a heat exchanger with an inlet and an outlet, and joined by the inlet portion to the second end portion of the coiled tube and joined by the outlet portion to the hot water outlet tube, in such a manner that the inlet tube, the outlet tube, the coiled tube and the heat exchanger define a water flow conduct, the temperature sensor being attached to a regulator mechanism and located in any part of the water flow conduct; a heat source is concentric the heat collector; and an activator is connected to the heat source and the temperature sensor.</p> |
