A hot water circulation pump can  make a morning shower much more pleasant. You won’t have to wait for the water  to heat up before you jump in and soap yourself. That wait, which can seem  endless when the weather is bitter and wintry, occurs because the hot water has  to travel all the way from the hot water tank to the shower. A hot water  circulation pump gives you hot water where you need it, when you need it,  without any waiting. It's something to benefit all homes.  
                                 
A hot water circulation system includes these features:  
 - A pump circulates water through the water heater. 
 
- A thermostat controls the temperature in the return line by automatically  switching the pump on or off to keep the temperature between 95 and 125 degrees  Fahrenheit. 
 
- A timer activates the thermostat to check the temperature at built-in  intervals. 
 
- An optional programmable timer allows homeowners to regulate how often the  timer and thermostat turn on.
