What is a hot water recirculation pump?

Recirculation Pump

Well, a hot water recirculation pump plays a crucial role when it comes to putting hot water where you need it, in a timely manner.

You’ll find this type of pump mostly in your hot water heater.

The main function of these pumps is to return the unused hot water all the way back to the water heater.

Needless to say, a hot water recirculating pump is definitely the solution for hot water on demand.

The recirculation pump plays a crucial role in saving thousands of gallons of water over the year.

In simple words, it will save you both water and money as it provides you with the convenience of having hot water in your faucets and showers whenever you want it, and of course, without any hassle.

What is the main purpose of a recirculation pump?

To be honest, the main purpose of a recirculation pump is to provide you with hot water wherever and whenever you need it, and as close to the consumption point as possible.

Not only does it enhances the comfort and convenience of the end-users’ but also reduces water wastage and energy consumption.

In simple words, the water heaters with recirculating pumps are definitely environment friendly.

Things You Need To Consider When Buying A Hot Water Recirculating Pump

Before we start reviewing the hot water recirculating pumps, it is equally important that I walk you through the important parameters that you should look for when it comes to buying the pump.

It goes without saying that the market is flooded with a wide range of recirculating pump brands and models, and trust me, each one of them has its own claim of being superior to its competitors.

Correct me, if I’m wrong.


A timer is an important component of not only a recirculating pump but any power tool, isn’t it?

In fact, it can play a crucial role in automating the functions and the process, and as a result, you end up saving a good amount of time that you can utilize it for some other important tasks.

What I actually mean is, having a timer gives you the feasibility to schedule the shut-off at your convenience.

And the best part is, you can get a timer fitted to your recirculating pump in case, it doesn’t have one.


Who doesn’t want to buy a product that is durable, right?

So, always look for the recirculating pump that is made up of durable materials such as high-quality stainless steel.

And, trust me, you need to opt for a durable recirculating pump in case, you want it to last for 5 years or more.

There are high-quality premium recirculating pumps that can last for a decade or even more, and the credit goes to the high-quality materials that are used in its manufacturing.

Pump Housing Material

The durable material alone isn’t gonna solve all your problems for sure.

For example, when it comes to selecting pump housing material, you need to opt for aluminum pump housing as compared to cast iron as the latter is definitely not viable for potable water use.

Needless to say, cast iron causes rust within the system.

Tankless Water Heater vs. Traditional

The prerequisite of a tankless water heater is a powerful pump.

Moreover, if your water supply is based on a shallow well pump, then, a recirculating pump will have a difficult time heating the water.

However, most of the hot water recirculating pumps don’t have the necessary power to work with either the highest-quality gas tankless water heater or even an electric tankless water heater.

What I actually mean is, you can’t ignore your water heater rather you need to take it into consideration before buying a pump.


I have got a piece of good news for you, most of the hot water recirculating pumps don’t have to be primed and can run with some air in the lines.

Nonetheless, there are pumps that have to be primed and will not work when air is present in the lines.


Always look for the products that comes with a longer duration of warranty.

The more the warranty the better it is.

However, I recommend you not to opt for the hot water recirculation pumps that don’t come with a warranty.

In simple words, the warranty is a clear indication of how confident the manufacturer is about its offering.


Not only for recirculation pumps but for any product, pricing plays an influential role, right?

However, as per my experience and knowledge, I can affirm that the cheapest products aren’t always the worst, and the costliest isn’t always the best.

So, what I would be suggesting is to look for the products that not only cater to your requirements but also fall well within your budget.

Best Hot Water Recirculating Pumps Buying Guide

I hope you would’ve thoroughly enjoyed the review of some of the best circulating pumps available on the market, right now.

Moving further, I would be walking you through some of the “must-have” parameters that you shouldn’t overlook when it comes to buying a circulating pump.

Types of Hot Water Recirculating Pumps

Well, if you’re a first-time buyer then it is really important for you to have some information about different types of recirculating pumps so that you can make an informed buying decision.

Mainly, there are two types of hot water recirculating pumps that I would be discussing today.

Full Recirculating Pump System

If you’re planning to buy a full recirculating pump system then you’ve to use an additional pipe.

The additional pipe is solely designated solely for hot water.

If you’re not aware of where the additional pipe would be installed then let me tell you, the additional pipe need to be installed in the plumbing of your home and attached to the pump.

Most importantly, the pump needs to support this type of system, so you need to check it carefully before you make the final decision of buying.

In case, you’re not aware, then let me tell you, the full circulating pump system creates a loop.

What I mean by creating a loop is, the hot water will travel from the water heater to the faucet and vice-versa.

In fact, the system will draw the unused hot water back through the aforementioned loop with the help of the hot water pump.

Therefore, the wait will be drastically reduced, and you’ll be greeted with hot water as soon as you’ll open the faucet.

And, the best part is, the system will prevent the water from getting cold by drawing it back into the heater via a quick delivery.

However, some of my clients have felt that the system is a little bit expensive.

Let’s have a quick look at some important points that you can’t afford to skip.

  • The water heater is running continuously with water in an endless loop within it
  • Despite that, the system doesn’t affect energy and gas costs as much as you did think
  • Some of the premium pumps do come with sensors and timers that increase their efficiency and decrease their energy consumption
  • Let’s understand it this way, a sensor will shut off the pump as soon as it finishes a loop
  • On the other hand, a timer will let you control the active times of the pump
  • Lastly, the cost of the additional pipe can be quite high and because of it, quite a few people who are on a shoestring budget opt for the other option

Recirculating Pump Comfort System

The recirculating pump comfort system is definitely the option that you should look for especially if you’re on a budget.

This type of system uses the current cold-water pipe to send the unused water to the heater.

In this case, pumps come with a simpler design and are highly affordable.

Frankly speaking, this is one of the most cost-effective solutions when it comes to hot water recirculating pumps and systems.

The comfort-type system is able to provide you with hot water quickly, towards the areas of your home that have an issue with getting hot water fast.

In case, the water supply is far away from your kitchen or shower, a circulating pump using this system will solve your queries.

Please allow me to highlight some of the key aspects of this type of recirculating pump.

  • Unlike the aforementioned types, in this case, you don’t have to install any additional pipes, thus lowering the initial cost of the system
  • But, it also has its own share of cons as well. Let’s understand it this way. For example, since hot and cold water share the same pipe, the cold faucet may contain lukewarm water or even take some time to get cold
  • Well, if you’ve swamp cooler, the issues we mentioned above may be somewhat more serious. This is why most users turn off their pumps during the summer

Is a hot water recirculating pump worth it?

To be honest, I’m not the right person to decide for you whether a recirculating pump is worth it or NOT.

Trust me, it’s ONLY you who can decide.

Nonetheless, in order to help you make an informed decision, what I can do is, walk you through the pros and cons of having a recirculating hot water pump.

Does it make sense?

Hot Water Recirculation Pump Installation Pros And Cons

It goes without saying that anything and everything in this world comes with its own shares of pros and cons, and trust me, hot water recirculation pump installation isn’t an exception at all.

But, at the same time, the positive thought and the mindset do matter, and of course, for good reason.

Without wasting any time, let’s have a quick look at both the pros and cons of a hot water recirculation system.


  • Small, compact, and can fit under a sink
  • You can install it quickly and easily without any hassle
  • The timer that it comes with allows you to run the pump from a remote location
  • Capable of providing instant hot water to any type of system
  • A system based on a hot water recirculating pump wastes less water
  • And, of course, AFFORDABLE


  • Hot water recirculating pumps require a power source near the installation which can be a headache if the pump happens to leak
  • Such pumps are characterized by low output in cold climates

Does Hot Water Recirculation Pump ACTUALLY Save Money?

Whether hot water recirculation pumps save money or not is an aspect worthy of debate.

And, the simple reason for it is that their are loads and loads of people that claim that they couldn’t save a single penny out of it.

Again, why they couldn’t save money is a question mark?

  • Cheapest pumps are available at as low as 200 dollars but should you opt for a premium variant or a cheaper one again depends
  • As you will most likely have a timer pump, let’s assume that you set it to run for 3 hours per day, during peak times. Depending on the unit’s wattage, you will spend around $20 to $30 per year on energy
  • Obviously, we do have to take heat loss into account as well. This depends on the temperature difference and on the distance from the heater to your faucet. Let’s assume that, as a result of heat loss, you’ll lose around $100 a year
  • Now, in terms of saving water, 5000 gallons round up to approximately $25 in savings, depending on the price per gallon. As most pumps claim to save around 15,000 gallons a year, let’s say that you would save around $75

By analyzing the result and using your common sense, it wouldn’t be a tedious task to come to a conclusion, right?

As per my knowledge and understanding, even though you’re not able to save money on the unit still it isn’t a bad deal at all for sure.

To be honest, all you need to spend is as little as $100 throughout the year to get the service of a recirculating pump.

Nevertheless, if the system is helping you to save the water worth $50 per year, then I don’t find any reason why shouldn’t you opt for it.

How To Install A Hot Water Recirculation Pump Effortlessly?

Well, even before we start the discussion on hot water recirculation pump installation, let me tell you, almost all the pumps that made to our list can be easily installed irrespective of you being a newbie or a seasoned professional.

Again, tools required for this process are minimal which varies from just a wrench to a couple of tools.

It’s good to follow the instructions and steps that we’re gonna discuss in a while but at the same time, my suggestion would be to not skip the instruction mentioned in the manual.

At times, some recirculation pumps may have specific requirements that if overlooked would result in a faulty installation.

Tools and Materials – you will need a recirculating pump kit (including check valve and flex supply tubes), a screwdriver, channel-type pliers or pipe wrench, a bucket, and a towel.

The pump will require a 120-volt outlet. Some additional parts and plumbing work may be required, depending on the configuration of the pump and/or of your home’s plumbing.

Install your hot water recirculating pump with these simple and easy steps.
  • Shut off the water on the shut-off valves found on the cold-water pipe that is running into the water heater.
  • Make sure that the water flow is completely stopped.
  • If the flow fails to stop, you may need to shut off the house’s main water supply.
  • Disconnect the flexible water supply line found on the hot side of the water heater.
  • Keep a towel or rag close, as residual water may come out of the pipe.
  • Screw the pump on the hot side of your water heater.
  • Make sure that the face with the timer is turned towards a direction where it can be accessed from.
  • Reconnect the hot water line to the top of the pump and then tighten the assembly with channel-type pliers.
  • Make sure that there are no kinks that may restrict the water flow.
  • Move to the sink farthest away from the water heater.
  • Here, you will install the check valve.
  • Shut off the faucets’ water by closing both of the supply valves that are controlling the cold and hot water supply tubes.
  • Then, you will have to disconnect the supply tubes of the faucet from the shut-off valves found under the sink.
  • You will now have to connect the check valve to the supply tubes of the faucet.
  • The existing supply tubes that come down from the tailpieces of the faucet have to be screwed onto the top two outlets that are on the check valve.
  • The hot water line has to be positioned on the left and the cold one on the right.
  • Run the new water supply tubes from the check-valve to both hot and cold shut-off valves.
  • Make sure that these are connected to the proper valves.
  • Once the new supply tubes are tightly connected, the check valve can be mounted to the wall, with the help of the screws that came with the kit.
  • The water has to be then turned back on to both the water heater and the sink faucet.
  • You have to let the water run at the far sink until all the air is out of the water lines.
  • Before plugging the pump’s power supply in, make sure that there are no leaks.
  • Finally, you can set up the pump via the timer.

How long does it take to install a recirculation pump for a first-time buyer?

Frankly speaking, almost all the recirculating pumps that made to our list wouldn’t take more than a couple of hours even though you’re a first-time buyer.

Is it possible to avoid and prevent corrosion in a hot water recirculating pump?

Of course, it’s POSSIBLE.

By following some simple tips and tricks, you would be able to deal with problems such as corrosion in an effective way.

The main reasons that contribute to the corrosion are aggressive chemistry and excessive flow velocity.

Moreover, because of the aforementioned issues, the pipe gets eroded from the inside.

Elbows, bends, and the tees around thin walls are mostly impacted.

By choosing a lower capacity hot water recirculation pump, you can deal with corrosion in an effective way.

On top of it, you also need to reduce the abrupt changes in the pipe directions in your home plumbing.

How long do hot water recirculating pumps last?

Well, almost all the recirculating hot water pumps that made to our list can last somewhere around 10 to 15 years if you’re not trying any misadventure, rather running them as per the manufacturer’s specifications and also, provide them with the maintenance they need.

Still, the outliers are there that need the helping hand of plumbers for installation.
