A method controls an air handler that generates heated air from hot water generated by a water heater. The method includes generating a signal in the presence or absence of an indicia of water flow associated with the water heater; initiating operation of a pump associated with the air handler when the signal indicates that water flow associated with the water heater is at least at a selected level to supply hot water to the air handler sufficient to generate heated air; and/or terminating operation of the pump and/or a blower/fan associated with the air handler when the presence or absence signal indicates that the water flow associated with the water heater is less than the selected level.

1. A method of heating air in an air handler from hot water generated in a water heater comprising: receiving a call for heated air;automatically initiating operation of a pump associated with the air handler;continuing operation of the pump for a predetermined first period of time;detecting whether a flow of water through the pump is at a predetermined level sufficient to generate heated air from the hot water;responsive to detecting that flow of water through the pump is not at a predetermined level sufficient to generate heated air from the hot water, terminating operation of the pump for a predetermined second period of time and then repeating the initiating, continuing and detecting steps;responsive to detecting that flow of water through the pump is at a selected predetermined level sufficient to generate heated air from the hot water, maintaining the pump in operation;initiating operation of at least one of a blower and a fan to supply heated air generated by heat exchange with the hot water; andautomatically terminating operation of at least one of the pump, the blower, and the fan when the call for heat is satisfied. 2. The method of claim 1, further comprising generating a signal in the presence or absence of the flow of water at the predetermined level. 3. The method of claim 2, wherein, when the flow of water is below the predetermined level, operation of at least one of the pump, the blower, and the fan is terminated and, after a predetermined second period of time elapses, the flow of water is re-verified. 4. The method of claim 1, further comprising terminating operation of the fan after the call for heated air is satisfied. 5. The method of claim 1, wherein the water heater is tankless.
