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

Q: Will this pump support 3 valves?
Asked by Mark 10 years ago

Verified Reply- SupplyHouse StaffYes, the Comfort Hot Water Recirculation pump may be used with multiple thermal by-pass valves. This set-up would be required when the home has a branched hot water line.

Verified Reply- Supplyhouse StaffYou should confirm with the manufacturer of your tankless heater, as some manufacturers void or cut your warranty in half is used w a recirculator pump.
Q: I have a 6 unit apt bldg., which has a basement (where my hot water tank is located), a first floor (not using this hot water tank), and a second and third floor. Will this pump be able to circulate hot water up 3 floors, and across the building (roughly 50 feet)? If not, do you have any suggestions? Thanks!
Asked by Andy 10 years ago

Verified Reply- SupplyHouse StaffThe pump should be able to handle such a distance, as explained in the installation manual "For the greatest effect, the valve should be located at a faucet with the greatest piping distance from the hot water heater." If your home has a branched hot water line, more than one valve may be necessary
Q: My Home is two stories, with the upstairs bathroom as far away from the water heater (located in the garage), as the kitchen sink. Is it necessary for two comfort valves to be installed and if so, will this pump work properly under that condition. Thanks

Verified Reply- SupplyHouse StaffYes two comfort valves can be used with the one pump that is not a problem.
Q: My hot water system is already equipped with recirculation lines. My existing pump is plumbed in at the bottom of the tank. Can I use this one and just not use the included valve? Leaving my existing, non-functioning pump installed?
Asked by Jim 10 years ago

Verified Reply- SupplyHouse StaffIf there is a recirculation line installed, the UP15-10SU7P/TLC and Comfort Valve are not the best choice. This system is designed for homes that do not have a dedicated return line. The best course of action would be to replace the non-functioning pump.
Q: Can this unit be used in a system with a ground well? I'm concerned the pressurized tank would not allow the mixing valve to push hot water line thru the cold line. I would think the recirculating pump would be "fighting" the well pump.

Verified Reply- SupplyHouse StaffThere is no problem using this pump in a system with a well pump and tank.
Q: I need the answer from the manual page 5 and 6 but I don't have adobe reader on my computer. Can someone tell me how the pins are to be set for the timer? Are pins up for hot water or pushed in for hot water? CUSTOMER CARE A: It is on page 5 and 6 of the manual linked below: http://s3.supplyhouse.com/manuals/1294349331588/43377_PROD_FILE.pdf

Verified Reply- SupplyHouse StaffThe manual states: 1. Set the timer switch to the actual time by turning the programming ring in the direction of the arrow until the timing arrow points to the actual time on the ring. 2. Plug in the power cord from the circulator and set the manual switch to the "ON" position. The circulator will now start. 3. Set the required "ON"/"OFF" times on the programming ring by pushing the programming tabs either away from or toward the center of the ring. Tabs pushed away from the center indicate the circulator is switched "ON" while tabs pushed toward the center indicate the circulator is switched "OFF". 4. Set the manual switch to the "TIMER"position. The circulator will now start/ stop according to the settings of the programming tabs.
Q: can I install two of the pass through valves under two different sinks?? With only one pump at the tank
