The idea sounds great but the result is poor. A small pump with a 24-hour timer set for 30 minutes on, 30 minutes off is efficient and works great. Be sure to insulate all of your hot water pipes. Use PEX if possible.
Do recirculating systems that do not use a pump work very well?

I saw a Nibco recirculating system at a store it says that it works via convection, and needs a return line. Anyone know if these work as advertised? I am working on finishing my lower level off, and so have the ability to put a return line in place. Kitchen is about 40 feet from the hot water heater.
