A surface water heating system for irrigation is described. The irrigation apparatus comprises an irrigation manifold, a heat exchanger, a first conduit system, and a second conduit system. A geothermal heated fluid, e.g. water, flows through the first conduit system. A first pump extracts the geothermal heated water from a geothermal source and conducts the heated water through the heat exchanger, and returns the geothermal water, now cooled, to the geothermal water source. Surface water flows through the second conduit system. A second pump extracts water from a higher quality water resource such as a surface water resource and conducts the illustrative surface water through the heat exchanger. Subsequently, the surface water is delivered to the irrigation manifold. Within the heat exchanger, heat is transferred from the geothermal heated water to the higher quality water resource. The geothermal heated water does not come into contact with the illustrative surface water within the irrigation apparatus.
