This process is so fast that before the toilet finishes flushing you'll have hot water. Plus you save water, time and money!

The Metlund Hot Water D'MAND System is an electronically controlled pump and valve assembly that allows for the rapid delivery of hot water to the plumbing fixtures without the loss of cold water down the drain. The system works only when there is a demand for hot water. When the user activates the system by pushing the D'MAND button or the wireless remote button, the Hot Water D'MAND System pumps the hot water to the plumbing fixtures. Once hot water reaches the pump, the Hot Water D'MAND System completely shuts off by detecting a 3 to 4 % temperature rise so there is no loss of energy or water!
There are advantages to this kit over a pure D-I-Y job. They supply a flexible copper tubing to speed installation and temperature sensitive relays that automatically turn off the pump when the hot water reaches the faucet. This system can also be used at intermediate faucets on the line (such as in the kitchen or other bathrooms) by installing a separate switch and relay under each sink. It has a low voltage switch system, making the additional wiring easier because of the smaller wire size used, along with reduced shock hazard at the remote bathrooms... a good idea if you have kids.
They have a great schematic of the layout of these systems at the web site, that is worth looking at if only out of curiosity!
