The Check Valve Method: Options A and B shown at the right are examples of the Check Valve Method.

The Check Valve Method utilizes the existing standard home plumbing system. Clicking on each diagram will enlarge different components of the system so you can see how they work together to heat the water and bring it to each spigot.

The Command System is designed to move hot water from the hot water heater to your most remote fixture within your home. At the push of the command button, or at the set of a digital time clock the cold water you normally let run down the drain is recirculated back through the cold water lines as hot water is filling the hot water lines to your faucet. When the hot water arrives at the hot/cold exchange valve the system automatically shuts off.

The Return Line Method: The Dedicated Return Line Method, shown in Option C, negates the need for a hot/cold interchange to be installed under the sink, but requires additional pipe to be installed from the furthest sink to the hot water heater. This addition can be quite expensive when considering not only the pipe itself but repair of the walls afterward.This line may already have been installed in some newer homes as they were being built.

In options B and C, a small motor is placed at the hot water heater unit. The motor may be controlled by a remote control capability, such as is used with an automatic garage door, or by continual ON and OFF settings of a digital time clock with battery backup. Either the remote control or the digital time clock provides the actual turn ON and OFF of the water pump assembly.

Three basic systems are used to provide Recirculating Hot Water throughout a home. Options A & B are for existing residences. Option C is for new homes under construction.

Most homes have a somewhat different floor plan, therefore a different Hot and Cold Water plumbing layout. (No "one" type of system or KIT fits all homes), as my competitors have advertised at this time. Koenick Electronics Int'l. provides 6 different "Water Guardian KITS", which could be installed by a "DO IT YOURSELF" person in about an hour, with minimum tools.
