A self-regulating swimming pool heater unit to be utilized with single or dual pump pool filtration systems, the unit including a main unit housing wherein there is contained a refrigeration unit structured and disposed to emit heat, as a byproduct of its cooling cycle, so as to heat filtered pool water passing through an internal, coiled flow through path within the refrigeration unit. The heater unit further including a plurality of internally contained single pole, double throw switches, a first, second, third, fourth, and fifth of those switches being connected in series with one another such that only when all of those switches are positioned in their normally closed position, will the refrigeration unit be able to operate. Each of those first, second, third, fourth, and fifth switches being connected to a regulating device which will cause switches to move to an open position and will cause a particular indicator light to turn on. Further, the heater unit includes an automatic timer and an automatic timer bypass adapted to enable the heater unit to function even during periods of time not designated by the timer.
