Comfort Recirculation System

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

I am interested in installing a hot water recirculation pump so I can get hot water faster to each of my faucets and shower locations.

I know three types of recirculation systems, and here they are.

 

DEDICATED SYSTEM

 

The first type is the traditional dedicated (as shown) hot water return system found in some homes. This system was first used in the early 1970s. 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 of recirculation system is used when no dedicated hot water return line is 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, called "On-Demand" (as shown). This type is located at the farthest plumbing fixtures from the water heater and consists of a pump 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 installed at the water heater and uses a mechanical tee installed in a cabinet under a sink.

 

Whichever system is right for you, they all work fairly well.

PEX PIPING SYSTEMS

 

But what if you have a home that has polyethylene (PEX) piping

installed, and it takes a long time to get hot water to the faucets

from the water heater.

 

Cross-linked polyethylene (PEX), a flexible plastic type,

replaces traditional copper and galvanized steel as

water supply lines in new construction and remodeling

projects. Homes using this type of piping system have

drawbacks when it comes to hot water recirculation, usually

installed in new home construction and using hot and cold water

manifolds; usually, these manifolds are located in a garage or

utility area. Unfortunately, these systems are installed without a

third manifold, designated for the hot water return, so that all

faucets in the home have instant hot water without the wait.

Some say it can't be done. Water Heater Pros says, yes, it can!

The good news is that a hot water recirculation system can be installed in such cases. Expect limitations and extra out-of-pocket costs. But if you have a (PEX) piping system and really want instant hot water at some or all the faucets, call us at 916-344-4500. We have helpful hints and free quotes.
