Hi Mr. Haught,

Re-circulation loops are a luxurious upgrade. Many high end homes are built with them. I've even seen gravity fed re-circulation loops in elegant older homes.

If you install this upgrade I would suggest insulating all your hot water lines very thoroughly because uninsulated hot water pipes lose a LOT of heat.

  • Without insulation you might double your water heating cost.
  • Running re-circulation all the time is pretty expensive even if the pipes are insulated.
  • You might also consider either a 5 minute timer near your fixtures (so you can "purge" the lines when you need hot water), or a timer set to run at times you are most likely to want fast hot water.

If you are interested in doing this incrementally, the first step would be to insulate your lines.

You may find this improves heat retention in your lines to a level that you consider the problem fixed.

Good question, and good luck!
