Is it possible to have a hot water recirculation system and get hot water to all my faucets?

​

I am interested in getting a hot water recirculation pump installed so that I can get hot water faster to each of my faucet and shower locations.

​

I'm aware of three types of recirculation systems and here they are.

DEDICATED SYSTEM

The first type is the traditional dedicated hot water return system found in some homes, this system was first used in the early 70's, it consists of one or two separate dedicated return lines from the water heater to the farthest most distant plumbing fixtures such as a master bath and kitchen, this line is run back to the hot water heater. From there, a check valve is installed on the line with a pump leading into the water heater.

​

ON DEMAND SYSTEM

A second type recirculation system is used when there is no dedicated hot water return line installed. This system uses your existing water piping, and has no recirculation return line installed. Several types of new pumps are produced and used by plumbers, one type is called "On-Demand" (as shown) this type is located at the farthest plumbing fixtures from the water heater and consist of a pump that is installed under a sink, by pushing a demand button, hot water is quickly pulled from the water heater to this location.

COMFORT SYSTEM

A third type is called a "Comfort-System" (as shown) this system has a pump that is installed at the water heater and uses a mechanical tee that is installed in a cabinet under a sink.

whichever system is right for you they all work fairly well.
