The invention relates to the solar engineering, particularly to devices for conversion of solar energy into the heat one and can be used in the warm period of the year for heating the heat-transfer agent, for example water, for everyday necessities in the individual urban, suburban and rural type services. The solar liquid heater comprises a reservoir (1) with liquid, equipped with a branch (8) and formed of lateral walls (3), a bottom (2) and a floating cover (4), placed on the surface of the liquid with clearance (7) about the lateral walls (3) of the reservoir (1). The lateral walls (3) and the bottom (2) are made with a heat-insulating layer (6). The cover (4) is made in the form of a plane plate of transparent material. At least the bottom (2) of the reservoir (1) is covered with a light-absorbing layer (5). The branch (8) is placed at the bottom (2) of the reservoir (1) and is meant for inlet and outlet of the liquid. The upper part of one of the lateral walls (3) may be equipped with an outlet gutter (9) for overflow of the liquid excess quantity. The result of the invention consists in simplifying the construction of the solar heater by providing a high heating efficiency, in improving the functional performance and decreasing the fabrication cost.
