A conventional plan solar collector 1,22 m2, consisting of absorber plate thermally isolated and enclosed by sealed aluminum housing and smooth transparent glass 3mm, holds inside approximately 0.6 liters of water and works well in partly cloudy days for heating household water. This same volume of water if properly confined in a solar collector reflector type with parabolic cross section needs a few seconds for the water to change their physical state to steam above 100°C as long as acting over it the solar direct component. This project seeks to reconcile what is efficient in these two drawings adding to the axis of the parabola a jacketed vacuum tube with a small absorber fin, appropriating it to the variability of daily atmospheric transparency common in the South, Southeast and Midwest, envisioning the production of a new economic design and efficient for solar heating systems, fitting into smaller spaces, conciliating the industrial, commercial and residential needs for hot water production.
