Solar Water Heaters – Direct / Non-pressurized type
Direct-type solar water heaters are also referred to as non-pressurized solar water heating systems.
In the direct systems of solar water heating, the vacuum tubes receive solar radiation and are heated up as a result. The heat is then channeled into the water tanks. The quantity of solar energy that the solar water heater is able to transfer depends on its capacity to absorb light and its insulation from the external environment, which prevents the dispersion of energy from the solar water heater tank.
