I have a 50-gallon natural gas water heater. There is a return hot water line piped back to the water heater where I have a circulation pump that has since quit working. What type and model would you recommend?

The traditional continuous-running pumps -- although they save water -- end up wasting a lot of energy constantly heating water and circulating it around the home.

  • Most green builders are moving to on-demand hot water recirculation pumps, where you push a button and the pump turns on.
  • There are several manufacturers and some even come with a remote control so it can be used in several rooms. The button is typically put in the master bath or the furthest plumbing fixture from the water heater.
