A recirculating pump is a device that helps circulate water in a tankless water heater system. The pump helps to evenly distribute hot water throughout the system, and it also helps to keep the water in the system hot.
The pump is typically located near the water heater, and it is connected to the water heater via a pipe.
20 Best Recirculating Pump For Tankless Water Heater
1. Grundfos 595916 Comfort System Hot Water Recirculation Pump (UP15-10SU7PTLC)
Grundfos UP15-10SU7P TLC This quick and easy installation recirculator pump makes your hot water recirculation needs a snap. The Grundfos Comfort series uses the cold water supply line as the “return-line” to the water heater saving gallons of water every day.
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. This innovative model prevents you from wasting water as you no longer have to wait for cold water to turn hot whenever you turn on the faucet.
Hot water is always at hand because it continuously circulates from the hot water line to the cold water line and back to the hot water heater.
The idea is to keep hot water in the line, but not fill the cold line with too much recirculated hot water. It’s a compromise, and the recirc valve shuts when the hot side gets to about 95 degrees. This means the cold line has that temperature of water in it as well, which is great for a quick warm-water hand wash or dish rinse without even using the hot side.
I find it convenient, but for fully cold water I have to run it for a while, as it starts out warm and gets colder as the water flows. Fully hot water still takes time, but it starts out warm and gets hotter as it flows.
It’s OK for a sink full of dishes, usually I run it a bit while I rinse them off so it’s good and hot, before plugging and filling the sink. Either way, it sure beats running a gallon and a half of water every time I need it hot, and washing my hands in freezing ice cold water when I don’t want to wait.
The timer that comes with it is good quality, and multi-functional, but a little complicated until you get used to working with it. The display is pretty small, and hard to see without good light. It has plenty of programs to set OFF times if you have know when you will or won’t need the pump running.
The price and shipping were very good. The best on the web and $200. 00 less my local supply house`s (Plumb Supply and Ferguson). However One of the included fittings was incorrect, which was a big pain.
It requires two 1/2 inch lavatory (nps) x 1/4 inch compression adapters with rubber cone washers to connect the lav. supply’s to the return manifold I received one of those and one 3/8 nps x 1/4 compression adapter which is useless.
(I am sure it came from China that way so no surprise). Fortunately I had a 1/4 x 1/4 compression adapter and could splice two lav supply tubes together and make it work. That saved me another trip which means $100.
00. Now I have spent an hour griping, (Another $100). So who knows? It appears to have satisfied the costumer. There is some warm water feedback on the cold side as expected.
I have not installed this pump yet, and I am expecting that it will be exactly what I need. Note that although the product is listed as the “. comfort system 595916” that this is ONLY the pump. The sensor valve and connector pipes that are part of that SKU are not included.
As it turns out, that’s EXACTLY what I wanted — I have a dedicated return line from the far end which, by the way, is a far superior approach than using the sensor valve at the last faucet. However, using the sensor valve is an easier install if you’re not up for sweating copper or setting PEX, and it works pretty well.
What I also really appreciate about this pump is that it is of the old-style timer enclosure that has another knock-out for me to run wires for a thermal cutoff switch. The switch will detect hot enough water at the far end and also shut off the pump when the timer is on.
All in all, this turned out to be the best purchase for what I needed.
Grundfos UP15-10SU7P/TLC Comfort System (sku # 595916) is an all-in-one, easy to install solution for domestic hot water recirculation needs. This system is well suited for existing construction and can be easily intergrated without the need for running a separate return line.
Grundfos UP15-10SU7P/TLC Comfort System also includes a Timer, Line Cord, Comfort Valve (SKU# 595926) and Flexible Connectors, thus eliminating the need for purchase and installation of addidtional components.
Simply connect the lines, plug the pump into the electrical outlet and let the system do the rest.
This unit is controlled by a manual timer such that it can be set to operate on a daily schedule. The problem is that, when it is operating in one of the “on” schedules, the pump runs continuously. Of course this does insure that there is hot water available to all water faucets on the hot water line during the “on” cycle, but the pump does not stop running until the schedule comes to an end.
Ideally, it would be thermostatically controlled to run only when the hot water in the line drops below some set temperature, thus saving energy and wear on the pump. I found, also, that after several days, the pump, which was originally fairly quiet, began to get noisy.
Taco 005 Cartridge Circulator is designed for a wide range of residential and light commercial water circulating applications. Unique replaceable cartridge contains all of the moving parts so you can service it easily instead of replacing the entire unit.
Compact, direct-drive design and low-power consumption are ideal for high efficiency jobs.
This is a sweet little pump! We had to replace the pump on our potable hot water loop because a lazy contractor replaced our bronze potable hot water pump with a cast iron one. This in-turn filled our potable water system with rust (YUCK) and ruined our annual State EPA mandated water tests creating violations with our facility water system.
The TACO 008 was just the answer, besides being all stainless steel, the motor and the impeller consist of a cartridge system, so when it goes bad you just buy a replacement cartridge & 4 screws later your back in business.
This thing runs so smooth you have to feel the motor to know if its running. Easy to install and SupplyHouse has the BEST PRICE around, plus SUPER FAST SHIPPING!.
This was exactly the circulating pump I needed for our three story 8plex apt bldg. With 16 bathrooms and 8 kitchens I saw a 5x spike in my water bill when it got cold from tenants having to run a lot of water to get hot water to their apt.
This came in faster than my local plumbing supply could bring it in.
Never wait for hot water again! The Watts Hot Water Recirculating Pump provides hot water at every faucet or shower when needed, eliminating wasted water. It is easy to install on any water system and requires no additional piping.
The unique design of the pump ensures quiet, maintenance-free operation. The system includes a built-in 24 hour, dual setting programmIle timer to activate the pump only when needed.
Installing this pump on the hot water outlet side of my water heater and a hot/cold undersink valve to sink farthest from water heater. Has inproved the delay i would have waiting for the hot water to get to sink or shower.
I got it for a great price. The install was easy for me. I also sweated in a tee with a water pressure valve and a shutoff valve. No leaks whatsoever. I highly recommend this pump. I should be able to save and not waste more water waiting for hot water to come out of shower or sink now.
Many comments, first if you have a electric water heater, the bottom element should be set at your desired temperature ( 120’F), the top element is usually the master control, it should be set 10″F lower than desired temp( 110’F).
How it works, when running out of hot water the top element kicks in, once satisfied the control switches to the bottom element, which if set correctly heats all the water to 120’F. I switched from electric to gas, I had a time clock set for off peak demand, 7PM at night to 6AM in the morning, daylight saving time, since I never switched time, winter it would be actual 8PM to 7 AM.
Many comments about not working and not enough pressure, I have roughly 40 feet to my second story, also have a second temperature control for the downstairs bath. Comments about the pump not being strong enough, understand siphon action, like draining a water bed.
The cold water line becomes the siphon, it is important to mount this on the water heater as instructed, some water heaters have a baffle, this pump may not work, as to demand water heaters it will not work and actually will void the warranty of the water heater.
Some demand gas water heaters have this designed into the heater. So time clock, during normal wake hours I have it 15 minutes on and 15 min. off, during off hours I have it 15 min. on and 30 min off.
The way it works is once the water cools it allows flow until warm water reaches the temperature valve, having continuous on, eventually for long runs your whole hot water line will be only warm, by allowing it to completely cool for 15 to 30 minutes, the whole line gets hot water until it reaches that temperature valve.
Comments about mounting, this is the most complete kit I have ever seen, I have shut offs on all my sinks and shower, if you have modern plumbing, with individual hot and cold controls, it explains to leave the cold off, turn the hot on, opening the cold faucet you should get water out until the hot water hits the temperature control, and instantly shuts off.
Understanding how it works can be a asset. I also have a master tempering valve just after the water heater, this pump works flawlessly, on average it took 1 gallon to get hot water to the addition , yes some days getting up 4 hours late it is just above warm, I could change so it is 15 on and 15 off 24/7, but why bother.
I hope this helps, I should also point out that HD has the best price, just hard to find it unless you know how to search.
My original pump failed after 8 months so I contacted Watts and found the pump was still under warranty. Naomi at the Watts company handled everything the way every company should. she restored my faith there are still companies that have great products, great service, and well trained employees that stand behind their products.
This pump is awesome and gets hot water at the faucet quickly. I also love the built in timer so you can run it when you need it most. Buy it. you won’t be disappointed!!😊.
Their drive to provide the most efficient, reliable pumps in the industry can be seen across their entire catalog. Chances are you have enjoyed heating or domestic hot water thanks to a Taco 007-SF at some point in your life.
This pump is used by boiler manufacturers the world over as a component in their products. The 007-SF’s popularity is owed to its versatility and reliability. It provides efficient, single stage circulation across a range of applications.
The universal flange-to-flange dimension of the 007-SF makes it quick to install, even if you are replacing a different pump. A design that circumvents the need for traditional maintenance is coupled with durable components to provide you peace of mind.
The stainless steel construction of this circulator makes it ideal for applications where corrosion resistance is important. With Taco, your hydronic circulation is in good hands.
24 Jan. 2017 It is a ben (as in benefic) pump! Among the specifications: it consumes 70 watts; uses 120-volt AC supply. It operates quietly. I think that it is durable and that it should last many use-hoursor for multiple annums.
It has a replaceable cartidge which contains the impeller and the armature. The stator, which hardly wears out stays in the main bodyit’s not part of the replacement cartridge.
Needed a Taco circulation pump to fit an older boiler. Old model no longer manufactured. I was able to find which model replaced the old one on their site without any trouble. Called to confirm it was the right pump and all seals were included with it.
Received it in 2 days and free shipping. Fits perfectly and works great.
Taco oncommand systems are manufactured using the highest quality u. s. Made component parts available. Patented integral flow checks ifc are built into each oncommand pump to prevent cold water from entering the hot water line.
Patented act oncommand electronics are the controls for each oncommand system. This state-of-the-art electronics allows the system to accurately sense temperature and automatically shut off the system to maximize comfort and energy savings.
Oncommand systems are the only recirculation product that saves both energy and water approved by the us department of energy and state energy commissions. You can look forward to over 15 years of life expectancy with a taco oncommand system.
Includes: 00in cartridge circulating pump with built-in oncommand electronics, power cord, integral flow check ifc and mounting bracket starter button set of two 2 1/2in plumbing adapter tees set of two 2 1/2in stainless steel flex lines 115 volt 3, 250 rpm.
As a general contractor, I’ve installed this units for multiple clients, including my own house. The latest version is so quiet, I have to open the bottom cabinet door and get close to be able to hear the motor humming.
Hot water gets there much faster than just running water; that’s without wasting ever valuable resources, water!.
Commercial grade product that does what I wanted it to do. The installation involved adding a plug under the sink and that is likely not for the beginner. I put one in my last home and will be installing one in a relatives home next time I visit them for a couple of days.
We have two different circulation pumps. The Taco and a Watts. Their application depends on where you have power and how you want to start the pump. The Watts is in our bathroom. Since it is for warming the shower, and we shower about the same time every day the timer works great.
The Taco is for the laundry room. My wife starts the pump if she is doing a load with warm water. For that, the local control works perfect. All I say is a happy wife is a happy life.
The 0010-IFC with an Integral Flow Check is designed to reduce installation costs when zoning with 00circulators. Ideal for residential or light commercial hydronic or radiant heating, hydro-air fan coils, indirect water heaters or domestic water recirculation systems.
By locating the IFC inside the pump casing, a separate in-line flow check is eliminated, reducing installation costs. The reduced pressure drop of the IFC increases the flow performance over in-line check valves.
Both the IFC and cartridge are easily accessed for service instead of replacing the entire unit.
I have no way to evaluate this product. It is a pump. I don’t have the test equipment to check out the curve and power consumption of the ins and outs. It came very fast and the price was very good. Other than that, all I can say is that it works (pumps).
The Supply House is first rate. I have the equipment to rate them. They get most of my business.
Upgraded my 15 year old Hydro Therm mono-flow system with this pump and a new expansion tank. This pump is a quiet powerhouse and Supply House is a fantastic company. I will replace the boiler in the spring with a Weil Mclain Ultra 105.
The prices and service from Supply House leave nothing to be desired.
My leaking ancient B&G 1/12 HP, Series 100 NFI Circulator Pump was replaced by this 0010 Taco pump because it matched the specs closely. I have a simple two loop system in my rancher. Used the Gaskets supplied and this 0010 Taco fit nicely onto the existing flanges.
I removed the IFC, there is no need for it in a one zone system. Quieter, no oil and less electricity so they say.
The COMFORT PM AUTO range sets new standards for energy-efficient hot water recirculation in residential homes. Thanks to a low noise permanent magnet motor, energy consumption is reduced to as little as 5-8.
5 W. Utilizing AUTOadapt ensures the pump only runs when required. The result is maximum comfort with lower wait times for hot water, reducing water and electrical waste.
The pump has not come we are in the 7th day of waiting, fedex keeps giving us additional days was the 5th and now going to be the 13th. I contacted Pump Products and they did not help but told me to contact fedex.
Taco 008-CT-USK Pump with Under Sink Kit, 1/2″ Male NPT, 1/25 HP Taco’s On Command delivers hot water comfort and convenience to faucets and taps “On Command” 24 hours a day, and at the same time it saves water, energy and money.
The On Command is a small, silent pump that attaches to the hot and cold water lines in the cabinet under the most remote kitchen or bath fixture in the home. When the On Command is activated, the cool water you normally let run down the drain is recirculated back to the water heater through the cold water line.
When the hot water arrives at the faucet, the On Command heat sensor and control board shut off the pump to prevent pumping excess hot water into the cold water line. THINK GREEN: Installing the On Command can save the average family of 4 up to 12,000 gallons of water per year as it conserves our planet’s most precious resource, and reduces household energy and water consumption costs.
Runs only when activated by the user. Is available 24 hours per day / 7 days a week. Automatically senses when water is hot enough. Saves water, energy and money. Saves construction costs; No new return line needed and no need to drain the system.
Installed this pump under our master bathroom sink and we now have hot water in 3 seconds instead of 3 minutes! No more wasted water down the drain. Our double-vanity sinks both have hot water immediately now and our master shower has it in 10 seconds.
My wife and I really like the on-demand push button feature because our schedules are too variable for timer-based solutions. Even after the coldest night here on the shores of Lake Erie, this pump runs for only 70 seconds before it shuts off and we have hot (not warm) water at the bathroom sink faucets.
The pump is very well made and we can hardly hear it running when we push the button. Also, we don’t have the issue of warm water in the cold water line as some users of other brands have complained about.
We are super happy with this pump and wish we had installed it sooner! Supplyhouse pricing was the best! No regrets at all with this purchase!.
I’m not a plumber, but I was able to install this pump under the bathroom sink by myself, and that’s strong testimony. I did not use the connector hoses that came with it, I prefer the more flexible hoses from the hardware store, which have braided wire outer covering.
The hoses from supplyhouse were all metal, not as flexible. I also provided my own ‘T’ connectors; the ones from supplyhouse were not threaded on all ends, and I don’t know how to use that type. The button works great.
Pump makes some noise, but not too bad. Once I screw it down to prevent some vibration it should be better. The only mistake I made was hooking it up backwards. Then I saw the arrow pointing the direction the water should go, checked the instructions, and yup, sure enough, I had it backwards.
Easy to unplug and reverse, though, before my wife found out :-).
BEFORE, IT WOULD TAKE ONE AND A HALF TO TWO MINUETS TO GET HOT WATER TO OUR BATHROOM. NOW , JUST PUSH THE DOORBELL STYLE BUTTON AND 15 SECONDS LATER YOU HAVE WARM WATER, WHEN YOU TURN ON THE FAUCET, NO MORE WATCHING WATER GO DOWN THE DRAIN.
INSTALATION WAS EASY FOR A DO-IT YOURSELFER. YOU DO NEED A ELECTRICAL OUTLET UNDER THE SINK. THE SAME STYLE AS FOR YOUR GARBAGE DISPOSAL IN THE KITCHEN. IT ALSO HAS TO BE GFI PROTECTED. A ELECTRICIAN CAN DO THIS PART.
DO NOT OVER TIGHTEN THE FITTINGS, AFTER TURNING THE WATER BACK ON, ALITTLE SNUG OF THE WRENCH WILL STOP ANY DRIPS. ADDED PLUS, THE FACT THAT YOUR PULLING WARM WATER , USUALY TO THE FARTHEST SPOT AWAY FROM THE HOT WATER TANK, ANY FAUCETS IN BETWEEN WILL GET WARM WATER FASTER THAN BEFORE WITH THE PUSH OF THE BUTTON.
IT WILL EVENTUALLY PAY FOR ITSELF IN WATER SAVINGS, WISH I WOULD HAVE DONE IT WHEN WE BUILT THE HOUSE 10 YEARS AGO.
The Taco 006 Cartridge Circulator is designed for circulating hot or chilled fresh water in open or closed -loop, lower-flow applications. Unique, “00” family replaceable cartridge contains all of the moving parts so you can service it easily instead of replacing the entire unit.
Compact, low-power consumption design is ideal for high efficiency jobs.
This works perfectly as a recirculation pump for my tankless hot water heater with a very long run to the shower. It pulls minimal wattage (measured it at ~20 watts), and I measured it pulling ~1. 8 GPM through 80 ft of 3/4 and 80 ft of 1/2 copper pipe (including a slightly restrictive one-way brass valve).
I would bet that it could pull more without the restrictive brass valve on. The absolute best part about this pump is the quiet operation – even standing right next to it the noise is minimal and unobtrusive.
Make sure you have a proper bleeder valve in the system, as the pump cannot prime itself and purge air bubbles. I used a 3/4 shut-off valve with built-in bleeder for this purpose, worked great.
Works just fine. Was replacement for an old one of the same model. I found it impossible to get the old one out, so I took the new one apart and just used the motor parts. Been working great ever since.
Looking back, I should have purchased just the motor repair kit, but.
The Taco 0011-F4 Cast Iron Pump is specifically designed for high head / medium flow applications in Large Residential and Light Commercial closed loop Hydronic heating and Chilled Water cooling systems.
Ideal for high pressure drop Boilers, Fan Coil units, Heat Exchangers, large Radiant Heating and Heat Recovery / Geothermal systems. Exclusive Anti-Condensate Baffle (ACB) protects motor windings on chilled water jobs.
The unique replaceable cartridge contains all of the moving parts and allows for easy service instead of replacing the entire circulator. Universal flange to flange dimensions and orientation allows the 0011 to easily replace other models.

This pump replaced a B&G Series 100 Pump with 8 Feet of Head Pressure and 33 GPM. I always had issues in where the return temperature was off by over 30-40 degrees and it took over an hour before the old pump had a difference of at least 25-30 degrees.
This pump (NRF-36) within 10 minutes at start up does the trick. It is used for radiant heating applications. Because of the head pressure and speed I was able to move the air out of the system without having to fast fill the system.
Also it is a great pump if you are going to add extra zones for radiant in the future. This is all you need.
We use this product regularly whenever we need something larger than the NRF 25 that B&G manufactures. it has proven to be reliable for use with wall hung boilers that require an exterior circulator pump.
it is not an ECM pump but for applications requiring a fixed output, the three speed capability is very helpful in minimizing inventory.
This pump is the one we always spec these days to deal with high head applications like Rinnai’s and NTI boilers. This and the NRF-25 have replaced 6 B&G pumps we used to have to stock, making inventory much simpler to maintain.
Only negative is that with B&G shifting manufacturing to China, their has been a bit more in-warranty return than in the past, but I assume this is just a quality control issue that B&G is aware of and will be addressing over time.
Warranty return and credit has been no problem, regardless of supplier. PexSupply. com has proven to have excellent pricing, delivery times and customer service support and has become our primary Hydronics supplier over the last year.
Taco 008-F6 Cast Iron Pump Taco 008-F6 Cast Iron Pump>>The Taco Model 008 Cartridge Circulator is designed for a wide range of residential and light commercial, higher-head water circulating applications.
Unique, replaceable cartridge contains all of the moving parts so you can service it easily instead of replacing the entire unit. Compact, direct-drive, low-power consumption design is ideal for high efficiency jobs.
I wanted more flow in my circulating hot water baseboard heating system. A recently installed new furnace has a greater pressure drop than my 30 year old furnace resulting in lower flow rate and the slower heating of my house.
So, I replaced my 007 pump with a 008 pump, which provided more flow. But unfortunately the new 008 pump produced a whining noise throughout the house when the pump is operating. TACO said “the 008 has a higher head capacity meaning it can push more water thru the same piping system, the caveat is it is usually associated with more noise due to higher head pressure”.
This pump does a good job for me however the last one started to make a loud whining sound after about a year. The new one is now installed and working perfectly and quietly. Time will tell whether the noisiness comes back or not.

Premier’s Instant Hot Water Recirculating System is a pump and valve combination that delivers hot water in an instant to any faucet or bath in your home. It uses the pump at the water heater along with the patented under-sink sensor valve installed furthest away from the water heater.
This combination creates a pressure differential that allows the cold and cool water in the hot water supply line to “by’pass” (at a low volume) into the cold water supply line through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a “no-wait” temperature throughout the home.
The timer on the pump makes it more efficient during downtime. How Much Water is Wasted Waiting for It to Get Hot? Example: An average home has approximately 125 ft of 3/4 inch piping. 125 feet of 3/4 inch pipe holds 3.
14 gallons of water. 10 draws per day wastes over 31 gallons of water waiting for the water to get hot. Over a year, the wasted water equals 11,461 gal.

I now have 2 of these pumps in my outdoor wood boiler application. They are both working FANTASTIC. The 3 speeds are nice because you can turn it down for lower power consumption. The included 1/2″ NPT adapters are nice for making the pump easy and quick to change or service.
Over all this is a great little pump. Quiet, solid and just what I expected for power and reliability. However there was a problem with the threads on the easy connect fittings that came with the pump.
I really had to work with them to get them to screw on to the standard 3/4″ fittings and soldered the connections just to be sure. It seemed to be a possible manufacture defect, like their pipe threading machine had slightly the wrong pitch or gap between threads.
However once I worked around the problem and installed the pump into the system the operation has been great so far.
1st 20 minutes it started to smell hot. Unplugged 10 minutes later when smoke came out little hole. Tried 2 days later to same thing. Next day would not even turn on. Was told send pictures and videos.

I have this on a dedicated insulated return line and plugged into a smart plug so it turns off when I leave the house and at night. Been working great for several months now. Get the “union” model because it comes with built in check valve and a shut off valve.
Also insulate your hot loop, it will save a ton of money.
The person I talked with on the phone was very helpful and guided me to the right water circulation pump for our grundfos automatic adaptive pump that was causing us inconvenient issues. The new grundfos pump (basic, automatic, timed) pump is wonderful.
It was easy to install and just works. No worries. We will be back to the supply house for any of our plumbing needs.
I discussed on a chat whether to buy the this pump or the 98420224 model that was a hundred dollars more, and went with this one. It took about 15 minutes to replace the older 13 year old pump that had failed, and most of that time was finding the right tools.
Works perfectly, it is so quiet you can hardly hear it. I chose this over the more expensive one since I figured the minor savings from the adaptive controls would never cover the cost differential.
