Product Highlights
Description
Note: This item is for TANK water heaters ONLY. This item will NOT work with TANKLESS units.
Note: This style set up is illegal to install in the state of Massachusetts as it is considered cross contamination as it mixes hot and cold water lines.
Grundfos Pumps is proud to bring the comfort and savings of hot water recirculation to the existing homes market with the Comfort Series Instant Hot Water System. The Comfort System includes a Grundfos UP15-10SU7/TLC circulator and the revolutionary Comfort Valve. The stainless steel circulator, complete with timer and 10-foot power cord, is installed directly to the hot water discharge on the water heater. The Comfort Valve is installed under the sink at the fixture furthest from the water heater, and the system uses the existing cold water line to return hot water to the water heater.
The Comfort System is designed to give homeowners the added comfort and convenience of instant hot water and reduce the amount of wasted water. Unlike our competitor's products, there are no pumps under sinks (and thus no power required under sinks), no return lines required, and no buttons to push. Set the timer on the Grundfos pump and stop waiting for hot water.
Features:
- No return line required
- Installs in less than one hour
- No electricity needed under the sink
- Built-in timer & line cord
- Uses less energy than a 25-watt light bulb
- Can save up to 16,000 gallons of water per year, per household
- Includes timer, linecord, thermal by-pass valve, two valve mounting screws
- Timer is 24 hr, 3 position, 15 minute intervals
- Flex Hoses are included

Verified Reply- PexSupply StaffThis pump uses the cold water line as the return line back to the water heater. You will get some bleed over of Hot Water to the Cold side as the valve is closing. The design of this system is so that you don't have to tear down sheet rock to put in a dedicated return line. This system is for retro fit applications. So for houses that are not new construction. This system prevents you from having to tear down sheet rock in the house. So the valve that goes under the sink at the furthest fixture from the hot water heater is tying the hot water line and the cold water line together. When there is not warm water at the valve from the Hot Water side, the valve stays open. Once the pump turns on via the timer, it starts to push the hot water to the valve. Once the hot water reaches the valve, the valve begins to close at 93 degrees and is fully closed at 103 degrees. What you are experiencing is the bleed over from the Hot Water into the cold side before the valve is closed. You will always have a little bleed over from the Hot side to the Cold side before the valve closes.
Q: I have a tankless water heater which is located on an exterior wall outside. When it was installed it included a Grundfos pump which provided excellent hot water instantly. The pump has gone out and now it takes 3-4 minutes before hot water flows to our sinks. In researching a replacement, I have learned that these pumps and timers are for interior use only. Is there one that can be installed outside. I am in So. CA and have mild winters, but hot summers. What should I do?

Verified Reply- PexSupply StaffAccording to the manufacturer, they do not have any circulators or pumps that would do the same flow and head that would be able to be placed outside.
Some hot tubs use grundfos exterior pumps Connected by DROID on Verizon Wireless
Q: We are setting up our house with a home run system. So every fixture has its own line run to it. Will we have to put a valve under every sink or shower we want instant hot water at?
Asked by Sterling 14 years ago

Verified Reply- PexSupply StaffYes, you will need a valve for each run of pipe.
no need for a reversing valve when you have a hot return line back to the tank.... thats what the valve does... give you a "home run" line return back to the water heater for those systems that dont have a return pipe. You could use a different pump model (dont know what model it would be) that is only a pump, no reverse valve. some pumps"pull" the hot water back thru the return line and back into the tank and some pumps "push" hot water out of the tank outlet to the fixtures.
I'd advise you to ask your plumber/contractor as I'm sure what you mean by home run....from what I was told when I called my plumber was that if I had a return line in place (a single line that all sinks/tubs/baths fed into for hot water) I wouldn't need any under- sink pumps, but a different recirulator which has the pump at the hot water heater. It was going to cost about $1500 to have a line installed. I had to install two under-sink pumps because I had a leak at one time in the line to my kitchen which had to be rerouted. So if you truly have individual pipes going to every water supply location, yes you'll need a pump at each one.
First, I'm not a licensed plumber.... Short answer is "yes". However, if you're using sub-manifolds in your design, you may be able to consider locating these valves close to the sub-manifolds - where several end-users get the benefit of the re-circed hot water. Good Luck!
Q: My old pump was on the cold water inlet to my gas water heater, and it was installed horizontally with a valve to isolate the pump. 2 questions: 1) Is it okay to install this pump on the cold side? 2) Will it perform if it is installed horizontally rather than vertically?
Asked by Pleased as Pump 14 years ago

Verified Reply- PexSupply StaffAccording to the manufacturer, the Grundfos UP15-10SU7P/TLC pump can be mounted in a horizontal pipe as long as the pump shaft remains in a horizontal position. The pump is designed to be mounted on the outlet of the heater.
Q: My pump was installed about 3 yrs. ago with one valve under the master BR sink & it worked great until a couple of months ago. It's plugged in, the timer is working, but it seems to have lost the pumping capability. Could it be the valve? Or is it more likely the pump? And, whichever it is, please advise on what action to take.

Jim, I'm not a plumber, so not really sure I can be of help. I seem to recall however, that somewhere on the PEX website there was a manual for the valve that had a troubleshooting section. My guess is that if you go through the steps it will assist you with figuring out it the pump is working. Good luck!
Turn the pump on and see if it vibrates. If it does - disconnect the output side and see if water is coming out. If it is not vibrating when you turn the pump on- then it is the pump
Q: I have a manifold system in my house. Do I only need 1 pump, the a check at every zone off the manifold?
Asked by JS 14 years ago

Since the pump will be installed at the hot water tank you will only need one for each hot water tank. "Ability is what you're capable of doing, Motivation determines what you do. ATTITUDE determines how well you do it". Thanks and have a great day!
I have quite honestly not installed the 2 mixing valves yet as I'm waiting for a stand for the water heater. I did, however go to several plumber forums and confirm was needed for more than 1 zone. hadn't considered using check valves though. Desmond Harmon-Smith ***.****
No one pump is insatlled at the tank and the cross over is under the sink furthest away Sent from my iPhone
Correct if I understand your question. One pump at hot water heater and a control valve for each leg of manifold.
Q: Are these efficient enough that you can just place them into the "on" position and not worry if you will have hot water - if I run the pump continuously how long should expect it to last?

Verified Reply- PexSupply StaffYes, this pump is efficient enough that you can just place it into the "on" position and not have to worry about it. There is a timer on the pump as well that you can set for this.
Q: Can this pump be purchased without the timer?
Asked by 14 years ago

Verified Reply- PexSupply StaffNo, this pump is only available with the timer.
Q: The description says that the existing cold water line can be used to return hot water to the water heater. Wouldn't that make the cold water line hot, so when a person went to get a drink of cold water it would actually be hot water that used to be in the hot water tank, and the person would have to wait until fresh cold water filled the line thus wasting water? I could only see this being useful for a shower or bath tub water lines if the lines ran directly from the hot water heater to the shower and didn't feed anything else on the way.
Asked by Luke 14 years ago

Verified Reply- PexSupply StaffThe line that feeds the water heater is normally branched off from the main (cold) line. If you push the water into this line after the separation from the cold line, it would not be part of the feed for cold fixtures.
Q: This seems to be for in-door placement. My electric water heater is in the crawl space below the house. The area would be protected from rain/snow/ice, but not completely from hot and cold temperatures of middle Tennessee. Can I install it in the crawlspace?

Verified Reply- PexSupply StaffWe don't see any issue with installing the unit in a crawl space. As long as water isn't freezing or turning into steam, you should be fine.
