It will not excessively heat the cold water line. If you use a reversible pump, the control circuit stops the pump as soon as it senses that the hot line has become hot. (That's how most hot water recirculating systems work.) If you just run the unit, the water coming out the bottom of the tank would be warm at most until the tank is full, at which point it should turn off as there's no point in continuing to heat a full tank.
