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 plumber installed this pump and timer upside down. Will this have a negative affect on it's operation? He says the arrow located on the pump must point towards the water heater. So, if it was assembled correctly, the nameplate and timer dial are mismatched. It seems to be operating okay even though it is difficult to program the timer due to its upside down position.

Verified Reply- SupplyHouse StaffAs per the installation manual "Install pump onto the water heater discharge, using the 3/4" female fitting and gasket supplied on the pump ensuring that the pump shaft is horizontal. The pump should be installed so that the pump is pumping away from the hot water heater, towards the house. Confirm the direction of pumping by observing the flow arrow on the side of the pump housing." The flow going the opposite direction could definitely impact the usefulness of the pump's recirculation.
Q: I have had this pump for 3-4 years and it works great for hot water. I have an ice maker in my basement bar that has not been working properly for a year. I think we have finally figured out that the ice maker electronic board will only allow ice to be made for 17 minutes and the temperature of the water coming in is about 100 degrees. It needs to be 85 degrees or less. How can I adjust the pump so that the water is not too hot on the cold side to allow the ice maker to function properly? I am not sure if the timer is on or if that would affect the cold temp.

Verified Reply- SupplyHouse StaffThe comfort series pump system works in the following way: The valve under the sink stays open, allowing warmish water to flow into the cold line until the water temperature reaches 98 +/- 5 deg F. At this temperature, the valve closes keeping the warm/hot water in the hot water line. Thus, there will be warmish water traveling to the cold line, at the sink where the valve is installed. This is creating a recirculation line from the cold line. The customer can greatly reduce the amount of hot water that bypasses into the cold line by using the timer to set the pump to operate during peak use periods. The valve needs to be installed at the furthest sink/fixture from the hot water heater. It is doubtful warmish water is traveling back to all of the fixtures.
Q: I am considering buying one of your units. But a quick question. My understanding is that the sensor is set at 103F. However, my dishwasher is connected to the same hot water line as my kitchen faucet. Standard specs for a dishwasher is for 140F to adequately clean the dishes. Can your sensor be changed to reflect this higher temperature, or is there another way to handle this situations. Thanks.

Verified Reply- SupplyHouse StaffThis model pump is used in homes without recirculation lines.The thermo-actuating valve closes at 98 deg F +/- 5 deg F. What this means is it will stay closed as long as the water is this hot, keeping the hot water to all fixtures. The valve should be installed at the fixture furthest from the hot water heater. This should not affect the operation of the dishwasher.
Q: Will this work with an on-demand (tankless) hot water system, specifically a Tagaki? Apparently, there should only be 2-4 gallons of water per minute. Thanks

Verified Reply- SupplyHouse StaffIn general, the Grundfos Comfort System (595916) will not provide enough flow to activate a tankless hot water system. We do not recommend using this pump and valve with a tankless heater.
Q: How do I set the timer? My plumber did not leave the booklet and we thought we would just let it run all the time, however, the hot water heater is near my bedroom and I can hear the pump running. It's loud enough to echo in the closet because there is no insulation to absorb the vibration of the pump. I would like to have it go off around 10:pm and come on around 6:am. It has the timer with the little pegs that you pull out and push in on the dial, and unsure how to set the "current" time location and if the timer goes off with the pegs out or in........ =0P Thank you.

Q: While this device may save a few gallons at each remote use, I am worried that the cost of uninsultated copper pipes might negate the savings. My guess is that we ask for hot water at a distance about 30 times per week so this costs 100 gallons, which is about 1/10 of our usage (not trivial in drought stricken CA). I bet constant hot supply and return lines is quite expensive. Engineeringtoolbox.com/copper-pipe-heat-loss-d_19 says 1/2" pipe loses ~30 watts/m. Our round trip length is probably ~50 m, so that's 1500w, like running a toaster full time. Monthly cost ~1000 KwHr. We pay about 15c/KwHr, so incremental cost would be $150/mo (3X less as it's gas-fired not electricity). Still $50/mo. Heat loss from insulated pipes is ~1 watt/m, 30X better, so just $2/month. My conclusion: it's ESSENTIAL to insulate pipes

Verified Reply- SupplyHouse StaffInsulation of the pipes will reduce heat loss. You can reduce heat loss and electricity consumption by setting the timer feature on the recirculation pump to only run at specific times of the day when hot water is in demand.

Q: During the time the pump is off, the hot water at the faucet could be cold, so the valve would be open. If I turn on the cold water at the faucet, will the water coming from the faucet slowly warm up until the hot water heats enough to close the valve, or is there some mechanism to prevent mixing hot and cold water prior to the valve closing?
Asked by Dr DOS 12 years ago
Add your answer
Verified Reply- PexSupplyStaffIf there is no hot water at the faucet or there appears to be too much hot water on the cold water side the following steps will determine if the valve is operating correctly: 1. Close the cold water angle stop valve below the sink. 2. Open the cold water faucet. 3. Water should slowly flow from the faucet until hot water reaches the valve. The flow should gradually decrease to a trickle of water until no water iscoming from the faucet.
Q: I am considering buying this pump. The comfort valve will be installed at the kitchen sink, that being the furthest point from the water heater. Will this system work with a single handle faucet, or do I need to replace the faucet ?

You will not need to change the faucet. The hot water valve installs before you're faucet connection. I have had this pump installed for a year now and it works great.
No need to replace the faucet Sent from my iPhone
yes it can be installed with any fixture. the cross-over or "comfort valve" connects under the sink at the hot and cold supply connections.
Yes it will. "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!
Single handle or two handle faucet should not matter. Charles Diliberto Plumbing & Heating, Inc. Times Herald, Best Of Montco for 8 Years. www.dilibertoplumbing.com
I should work with the faucet you have:-) Sent from my iPhone
Even if you have a single handle faucet, two lines are connected (hot and cold) are connected underneath- YES it will work.
no you donot have change single handle faucet the bypass will be done before the faucet under sink
It will work with a single handle faucet as long as you have both hot and cold supply lines in use with the faucet, as the valve diverts the hot water line water back to the heater in the cold water line.... hope this helps.
