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

Product Q&A
45 QuestionsQ: My water was off about 2 hours and now my pump seems to not be functioning, it is only about 10 months old. Was it damaged by the outage?

Verified Reply- PexSupply StaffIt's possible. This is a water-lubricated pump. If it runs while there is no water in the lines, the motor could blow out. This is known as dead heading.
Q: is this hot water recirulaation pump difficult to install by the person with some general plumbing skills and tools ?

Verified Reply- PexSupply StaffIf you have the proper knowledge and tools, it should not be difficult to install this pump.
Q: Can the UP15-10SU7P TLC be used with an instantanious hot water heater? Will the unit continually run due to flow?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe pump will have no problem. We recommend that you check with the manufacturer of the water heater to make sure you can use a recirculation pump.
the water heater will continually heat water because of the continuous demand for hot water. The water heater should shut off once the water being sent back to the heater reaches the desired temp set at the water heater. You can set the timer on the pump to run only during peak demand hours. you may experience more hot water on the cold side when you want cold water. check with the manufacturer recommendations on using return lines and re-circulation pumps.
Q: When I drained my hot water heater and turned the pump back on, it is now making a lot of noise. Can deposits from the hot water heater get in the pump and stop the pump from working?

Verified Reply- PexSupply StaffGenerally you would not need to if you install the unit on the farthest fixture.
Q: Can you get this (UP 15-10 SU7P TLC) with a thermostat? I think Grundfos calls theirs an "Aquastat". I know their model UP10-16B comes with timer and Aquastat, but only comes in 1/2" NPT.

Verified Reply- PexSupply StaffIt sounds like you are looking for part 595656 ( http://www.pexsupply.com/Grundfos-595656-1-2-Clip-On-Thermostatic-Control-for-Grundfos-UP-Series-Circulators ).
Q: I am installing a hot water recirulation system in my new home. The loop will be approximately 200 ft of 3/4" Pex in the home. I want to also send the water outside through a wood boiler and then back into the bottom of the hot water heater. This would add another approximtely 150' of 3/4" Pex. So I would have this pump on the wall above the water heater, 350' of Pex a hot water coil in a furnace, back into the hot water heater, through a mix valve and then into this pump. Would this pump be adequate, or should I go with a larger one?

Verified Reply- PexSupply StaffDepending on your GPM requirements, it may be necessary for you to go with a larger pump.
Q: Can this recirculator provide hot water to a 2nd floor baseboard heating system in a 2,400 sq.ft. home?
Asked by norbrook 15 years ago
Add your answer
Verified Reply- PexSupply StaffThis pump is designed for plumbing applications (to get hot water to showers and faucets more quickly). For baseboard heating systems, you will need a standard circulator pump. Sizing will be based on flow rate and head pressure.
Q: what maintenance is involved? How long have they been around and how long do they last?

Verified Reply- PexSupply StaffGrundfos is a European company that has been around for over 60 years. Their pumps usually last at least 10-15 years, with water quality playing a major role in pump life. This pump does not require any routine maintenance.
Q: I assume there are different model of this pump and different sizes depending on the pipes in my home. Where can I find a comple list of the various different models of this pump? Thanks.
