A solar energy water heating unit is provided which heats water from a swimming pool by passing the water through a series of spiral hoses mounted on a supporting surface. The supporting surface is mounted on a platform raised from the ground and is cone-shaped to allow for at least a portion of each hose line to be exposed to the sun at all times of the day. The spiral hose lines are mounted in spiral grooves provided on the supporting surface. A pump pumps the water from the swimming pool to the inlet of the hose lines, which inlet is adjacent the lowermost edge of the supporting surface so that the water is always pumped upwardly to the outlet end of the hose lines adjacent the apex of the supporting surface.
