In our manufactured home, the hot water heater is at one end of the house and the master bath is at the other... It takes forever for hot water to get to the master bath (wastes water while waiting).. Has anyone eve installed one of these Watts hot water recirc systems like the one in the attached picture? Do they work good? Appears easy to install... Comments...

I have seen them installed at a few houses in Lake Placid. What it is, is a continuous loop of 3/4 inch copper tubing all around the house where utilization devices are [ kitchen, bath etc] The hot water is taken off the top connection, goes into the "loop" and returns via a 3/4 inch tubing to a recirculating pump, then back to the hot water heater through the "bottom" connection - near or at the tank drain valve. Once through the loop, if the water temp has dropped, the bottom element turns on re-heating the water which goes to the top of the tank. When water is needed, the device is opened and water is right there - no need for it to travel the whole loop to be used. -
When you return back into the water heater you can take out the drain valve and put a tee in that line, Make sure you use a swing check valve so when you draw water it does not back feed out the bottom of the heater. You will also want to insulate the line as much as possible so you don't lose so much heat off the water lines. Some people put timers on them if they are not going to be there all day.

The Watts system that you are looking at along with a few others made by Grundfos, Laing, RedyTemp, and Metlund, utilize the cold water supply line to the last fixture where the recirculation system is installed as a return. They actually work quite well with the only downside being that instead of waiting for hot water you will wait for cold water with the water you initially get out of the cold faucet being tempered close to ambient temperatures. The pumped connection between the hot and cold is controlled by a thermostat which activates when the hot supply cools off.
