Residential Hot water Circulation Pump

| I need to know if a hot water circulation pump is as effective as advertised. Wouldn't you loose heat through the return cold water line? is it constantly running? I need to know from people that have installed such pump.
Thank you, |

they do work real well. but you are right you will lose heat on both hot line and return line. You need to put good pipe insulation on all the lines so you don't lose so much heat. If you want hot water all the time then it would need to run steady. if you don't need it at night you could put it on a timer. later paulbm |

| If you have a lot of pipe and it takes time to hot water to the faucet they are worth it. They are used mainley in buildings so instant hot water is available. You can install an aquastat in the line, possibly at the end and wire it in to your circulator. For example, set the aquastst at 130deg. When there is 130deg in the line it will shut the pump down. When the water in the line cools it will activate the pump to reheat the water. |

| hook it up to your bathroom light switch. when you turn on the lights it starts circulating water. |

| Make sure it's brass or bronze. |

| To answer your question: They are effective at reducing water waste and reducing the wait. They generally also increase energy costs because of the heat lost in the pipes - particularly in the summer when that heat has to be removed with A/C. They can be a pain to install properly. All hot water lines must be insulated AND you should install an insulated return line instead of using the cold water line as a return. |
