Description for Grundfos 595916

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

We used to wait for several minutes and waste 3-4 gallons of water each time we wanted hot water in the kitchen until I installed the Comfort Hot Water Recirculation Pump, 3/4" NPT, 115 V by Grundfos. now I get almost instant hot water. I have 2 zoned water heaters so I bought another for the master bathroom and have hot water in the shower almost instantly (3-5 seconds). It is fast and easy to install (about 30 minutes) and they include everything but a crescent wrench! I went with the Grunfos which is a little more than others because the pump is a metal housing and have used their pumps before.

I purchased this system in an effort to have instant hot water at the kitchen sink without the use of an existing five gallon electric hot water tank. I wanted to eliminate the worry of a tank leaking on the hardwood floor.

The system will keep hot water at the first two sinks inside the house. I'm very pleased by the results for those two sinks. However, the main purpose for the purchase was to eliminate the electric tank under the kitchen sink and it doesn't look as if that is going to happen. I've had the system for three weeks and even changed out the thermostatic controlled valve under the sink and still don't have hot water at the kitchen sink. I still have to wait for the hot water to reach the kitchen sink. Therefore, when the dishwasher is used I have to stand at the kitchen sink and run the hot water until it warms up enough for the dishes to be cleaned.

It seem to me if Grundfos simply provided an adjustable thermostatically controlled valve the customer could dial in the temperature they wanted at the last sink therefore creating a perfect system.

I hope Grundfos reads this and fixed the problem. If I only had hot water at the kitchen sink I would be a happy camper.

Used in a residential ranch style home. It normally took 1+ minutes to get warm water to the master bath, now is almost instant. I set timer to come on every other setting (15 minutes on and 15 minutes off) though out the day & totally off Midnight to 6AM. This is the most proficient use after several days of experimentation.

One caveat

By Ray the cyclist

from Mississippi

Comments about UP15-10SU7P TLC, Comfort Hot Water Recirculation Pump, 3/4" NPT, 115 V:

It was taking a very long time to get hot water in the kitchen. My wife was complaining. I bought this and the problem is solved.

The only problem that I had was with the installation. The plumber installed the pump on top of the hot water tank as shown in the instructions. My house uses the water from the hot water tank to heat the house. The pump when installed on top of the hot water tank pumped water through the heat exchangers in the air handling units and I got hot air out of the registers even when trying to cool the house. I changed where the pump was installed and now all is great. As long as the motor shaft is horizontal the pump can be installed at any angle, even up-side down which is the way I installed it. It makes setting the timer a little more difficult but it made the piping much simpler.

When you first turn on the cold water in the sink, it is just a touch warm but becomes normal cold quickly. When you first turn on the hot water in the sink it is only warm but it gets hot very quickly.

  • UP15-10SU7P TLC, Comfort Hot Water Recirculation Pump, 3/4" NPT, 115 V

    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 on 2/5/2014 by Dr DOS from CA

    1 answer

    • CUSTOMER CARE

      A:

      If 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.

      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.

    How do I program the unit so my cold water isn't also hot!?
    Asked on 6/26/2012 by Nellie from Pine Plains, NY

    1 answer

    • CUSTOMER CARE

      A:

      This 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.

    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?

      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.

      A:

      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.

    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.

      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.
