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.

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.

Water Recirculation Pump
By Grandma G.
from Lincoln, CA
Before it would take 2 1/2 gallons of cold water to run through my shower before I got hot water, now it's within a few seconds. At my kitchen faucet, there too, it warms up faster than before.

This pump made it posible to get hot water to the end of the home alot quicker and the timer helps us save money as well,i'm shure it will pay for itself in time!!
from Bremerton, Washington
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. NO DOWN THUMBS on this Item

A good pump -BUT!
from Hollywood FL
A Great piece of Engineering . Put the O Ring caned pump seal surface leaked. We had to drain the system and reseal with silicone sealer.
By Ray the cyclist
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.
Simple to install
Hot water with out the waitEasily installed with minimum toolsAlways a challenge to have a correct connecting hose

Does not work with Noritz Tankless
from Livermore, CA
We had this exact pump installed and it is not working with our Noritz Tankless Hot water heater. It will be removed by the plumber and he is going to get us a different brand.
