Solar heater having a collector wherein heat transfer fluid is heated by solar radiation and a heat-dissipating conduit operatively connected to the collector so that fluid from a return line normally flows through the collector and the heat-dissipating conduit. Flow control means are operatively connected to the collector and the heat-dissipating conduit so that at times the heat transfer fluid flows through the heat-dissipating conduit, the amount of said fluid flow increasing with an increase in temperature of said fluid and decreasing with a decrease in temperature of said fluid.
