A solar heater having a collector portion and a combined header and heat exchanger. The collector has a plurality of fluid passage means each individually in fluid communication with the chamber in the header. The plurality of fluid passages and chamber together with a condensate or fluid return passage provide a closed loop that is partially filled with a first liquid to be heated by solar energy. A conduit passes longitudinally through the chamber of the header for circulation of a second fluid to pick up heat from the first fluid. Fluid flow from the plurality of passages into the chamber is directly onto the conduit passing through the header. The plurality of fluid passages, in one instance, are provided by a plurality of conduits and, in another instance, passages are formed in two sheets of metal bonded together. The condensate or fluid return passage interconnects the chamber of the header with a cross-pipe interconnecting the plurality of passages at the lower ends thereof.
