A passive solar heater is described of the type combining a heat absorber and fluid storage in a tank adapted to be exposed to solar energy. The heater comprises: A unitary enclosure structure having side walls defining an interior chamber. The enclosure has an opening adapted to admit the sun's rays therethrough. The enclosure further has an exterior shell and interior insulative lining defining a generally central trough and interior side walls, portions of which are curved; a fluid storage tank has an inlet and outlet and being positioned within the chamber in the enclosure trough. The tank has a selective surface coating characterized by heat high absorptance and low emissivity. A sun reflective surface on at least the curved interior side walls reflects the sun's rays impinging on the reflective surface and re-directs the rays towards the tank.
