Isn’t it strange that even if you turn on the hot water tap first, you are still greeted by cold water for a few seconds? In fact, if you live in a very large house, you can even wait up to two minutes for hot water.

Let’s skip the conversation about the inconvenience in this case! The most important issue is that you waste water – lots of water. Every time you wait for hot water to come out of the tap, you’re wasting cold water and essentially money on your electricity bill.

Fortunately, this problem can be solved quite easily! See that when you turn off the hot water tap, the hot water in it does not return to the heater and instead stays stationary. Obviously, it will be cold in a matter of minutes. This can be solved with the best hot water recirculation pump out there – as these systems send the water back to the heater.

So let’s look at some reviews of the hot water recirculation pump and then learn all about these products – how, what it is and so on!

What Is a Hot Water Recirculating Pump?

In short, a hot water recirculating pump – or system – is responsible for putting hot water where you want it, in a timely manner. And by timely we mean fast. This type of water pump is usually installed on your water heater – even though we’ve heard of some unusual builds as well. The pump’s primary use is to return the unused hot water all the way back to the water heater.

As mentioned above, a hot water recirculating pump is the solution for hot water on demand – no more cold water in your faucets! Naturally, it is not everything about the convenience and pleasure of having hot water in your faucets whenever you want it. As you won’t have to let cold water run in vain until it gets hot, a hot water recirculating pump helps you save thousands of gallons of fresh water annually.
The lack of such a pump means wasted water and higher utility bills!

What Is the Main Purpose of a Recirculation Pump?

The main purpose of a recirculation pump is, by definition, to ensure the user that hot water is always available, as close to the consumption point as possible. This way, it greatly reduces water waste and energy consumption and increases comfort.
You can also see a recirculation pump as having two purposes:

  • First of all, such a product increases convenience within a household. You no longer have to wait for cold water to warm up and you can shower or such as soon as you turn on a particular faucet.
  • On the other hand, it is an amazing tool when it comes to saving water and decreasing utility bills via a low energy consumption product. Such pumps are environmentally friendly because they not only save water, but also energy.

In short, a recirculation pump is here to provide you with instant hot water at low costs and reduced waste!

What You Should Consider When Buying a Hot Water Recirculating Pump

When it comes to hot water recirculating pumps, we could say that the market is full of options but lacks guidance – so to speak. Basically, you can find a lot of models and types of pumps, but very little advice in terms of things that you should consider when buying one. Therefore, in the following lines, we’ll tell you what you should take into account when you are looking for a hot water recirculating pump to save you water.

  • TimersHaving a timer on your pump means that you can schedule it to shut off when you want to. In short, you get hot water only during peak usage times – depending on your settings. Remember that, even if your pump doesn’t come with a built-in timer, you can get one fitted into it easily.
  • DurabilityNaturally, durability refers to materials. You will want a pump made of high-quality stainless steel, especially if you want it to last more than three to five years. There are accounts of pumps that have lasted for as long as 10 to 15 years, mainly because they were made of high-quality materials.
  • Pump Housing MaterialEven if highly durable materials are important, you should also consider the use of the water pump. For example, pump housing made of cast iron renders the pump not viable for potable water use – as cast iron causes rust within the system. If you want to run potable water through the pump, then you will have to search for one with aluminum pump housing.
  • Traditional vs. Tankless Water HeatersTankless water heaters usually require pumps with more power. If your water supply is based on a shallow well pump, for example, a recirculating pump will have a very difficult time heating the water. As we mentioned in the review section, most hot water recirculating pumps don’t have the necessary power to work with either the highest-quality gas tankless water heater or an electric tankless water heater. In this respect, you must take your water heater into account before buying a pump.
  • PrimingUnlike a submersible well pump, for example, which has to be primed only once, most hot water recirculating pumps don’t have to be primed and can run with some air in the lines. However, there are pumps that have to be primed and will not work when air is present in the lines.

Benefits of Hot Water Recirculating Pumps

There are many benefits to using a hot water recirculating pump. Whether you’re looking to save or conserve water or you want to cut down on the water bills you receive, there are plenty of reasons why you should consider using a hot water recirculation pump. Some of the top reasons include:

Water conservation – The term behavioral waste refers to waste that occurs due to human habits. One of those human habits involves the warming of water. When you turn on a faucet, you have to wait for the water heater to warm it. When you turn it off, the process needs to be repeated again. In fact, 20% or more of every shower is water waste. Other estimates list the waste as high as 30%. This means that in America alone as much as 200 billion gallons of water is wasted per year.  A hot water recirculation pump can ensure that less water is wasted while you’re waiting for things to warm up.

Lower Water Bills – One of the easiest ways to lower the price of your water bill is to use less water. While some of that can be fixed by updating plumbing or faucets to be more efficient, in this context, it’s more about not having to waste water waiting for it to warm up. Depending on the amount of water you’re wasting, you could save hundreds of dollars or more each year and help the planet at the same time. It’s a win for everyone, especially your pocketbook.

Ease of Installation and Operation – The best hot water recirculating pumps are relatively easy to set up. Most of them can be installed with standard tools, most of which you likely already have in your tool box. Likewise, operating a hot water recirculating pump is easy to do.

How Do Hot Water Recirculating Pump Work?

Hot water recirculating pumps work by watching the water temperature (or time) and routing water appropriately. When the pump detects cold water in the line it sends it back to the water heater rather than into the sewers. Once the pump thermometer warms up from hot water it shuts off and starts to drain normally.

Do Hot Water Recirculating Pumps Save Money?

Yes! Your new recirculating pump will use electricity – usually $10 to $20 per year – but you will save much more than that on your water bill. Most normal size 4 bedroom houses in the USA save 10,000 to 20,000 gallons of water per year!

How Long Do Recirculating Pumps Last?

Most pumps – assuming you did not get a lemon – will last 10 to 15 years. The biggest factors that impact their life expectancy are the amount of water you use every day and the quality of the manufacturing. We recommend sticking with one of the “big name” brands like Grundfos or Laing.Extending Pump Life SpansWant your pump to last? Try to keep your line as clear of debris and particles. Also – the more water the pump has to process the quicker it will wear out so don’t run the shower before you plan to get in!

How to Install

Installing most pumps is easy and takes about 45 minutes and a few common tools. For exact instructions on your model it is best to check the owners manual or the company website. If that does not work try these steps to get started:

  1. Disable the water pumps and electricity to the outlet you will be working on. 
  2. Tell your family and roommates not to use any of the other sinks for the next 30 to 45 minutes
  3. Attach the pump, piping and any temperature sensors to the sink farthest from your hot water heater
  4. Run the cold water return line back to the hot water heater
  5. Turn on the water, electricity and test your new pump

Why Install a Pump?Unless you are planning on moving in the next 3 or 4 years it makes financial sense to install a pump and save money on your bills!

Recirculating Pump Pros and Cons

The pros of installing a pump in your home outweigh the cons but it still important to know what you are getting into before buying a new under sink hot water pump.

Pros

  1. Good for the environment. By saving thousands of gallons of water and electricity you can do your part to go green in 2019
  2. Good for your wallet. Using less electricity and water means small utility bills and more money in your pocket.
  3. Faster hot water. Without a recirculating pump it can takes a few minutes to get hot water to some parts of the house
  4. Easy to install without a plumber. Most pumps can be installed with a little DIY elbow grease and a few tools. 

Cons

  1. Needs an outlet nearby to run. This is not a problem as long as you have outlets under your sink.
  2. Must be installed under the sink farthest away from your hot water heater.
  3. Small investment. A good pump costs a few hundred dollars up front but will pay for itself over time.

Types of Hot Water Recirculating Pumps

Naturally, there is more than just one type of hot water recirculating pump. This is because, as you may know, there are water pumps that require the installation of additional pipes and so on – for example, some of the products described above. Therefore, there are two types of hot water recirculating pumps that you should be taking into account when choosing such a unit. Each type will require a different set-up, labor, and expenses.

  • Full Recirculating Pump SystemThe full recirculating pump system implies the use of an additional pipe, which is designated solely for hot water. The additional pipe will be installed in the plumbing of your home and attached to the pump, obviously. Naturally, the pump has to support this type of system, so make sure to check it carefully before you buy it.Moving on, the full recirculating pump system creates a loop – from the water heater to the faucet and back. The system will draw the unused hot water back through the aforementioned loop with the help of the hot water pump. Therefore, when you’ll be turning on your hot water faucets, you will be quickly greeted by hot water. The system prevents the water from getting cold by drawing it back into the heater via a quick delivery.There are a couple of things that keep this system viable, even though it is considered expensive by some people;
    • The water heater is running continuously, with water in an endless loop within it. Despite that, the system does not affect energy and gas costs as much as you’d think.
    • Most pumps come with sensors and timers that increase their efficiency and decrease their energy consumption.
    • For example, 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. This is why a lot of people choose the other option.
  • Recirculating Pump Comfort SystemUnlike the previous system, this one will make use of your current cold-water pipe to send the unused water to the heater. In this case, pumps come with a simpler design, so to speak, and are very affordable.This is the most cost-effective solution when it comes to hot water recirculating pumps and systems. If you don’t afford or simply don’t have the time to install the previous option, then this is the one for you!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. If your water supply is far away from your kitchen or shower, a recirculating pump using this system will solve all your issues.
    Here are some of the key aspects of this type of hot water recirculating pumps;
    • No need to install any additional pipes, thus lowering the initial cost of the system.
    • This type of system does have its drawbacks. 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.
    • If you have a swamp cooler, the issues we mentioned above may be somewhat more serious. This is why most users turn off their pumps during the summer.

The Pros and Cons of Installing a Hot Water Recirculation Pump

As we mentioned a couple of times so far, everything in life comes with both advantages and disadvantages. However, as the saying goes – you must take into account the full half of the glass, rather than the empty one.

Still, we are ready to introduce you to both the pros and cons of installing a hot water recirculation pump in your home. In the end, it will be up to you to decide whether you want one to solve your hot water issue or not.

Pros

  • Small and compact – can fit under a sink.
  • Built-in or fitted timers allow the pump to run when you are not at home.
  • It is very easy to find a pump on Amazon – and at great prices as well.
  • Very easy to install, operate, and perform maintenance on.
  • A system based on a hot water recirculating pump wastes less water.
  • Capable of providing instant hot water to any type of system/plumbing/house.

Cons

  • Certain models affect the cold water, making it lukewarm or getting cold after a couple of seconds after turning on the cold-water faucet.
  • Hot water recirculating pumps require a power source near the installation – which may be dangerous if the pump happens to leak.
  • Such pumps are characterized by low output in cold climates.
  • If your pump runs on a timer and you need hot water for a time when the pump’s timer is not set, then you will not enjoy instant hot water.

Do Hot Water Recirculation Pumps ACTUALLY Save Money?

Whether hot water recirculation pumps save money or not is an aspect worthy of debate. That’s mainly because there are people claiming they do not save money and are a waste of time and energy.
To prove or disprove the above, let’s take a look at the costs of having a hot water recirculating pump in your home:

  • One of the cheapest pumps you can buy costs around $200.
  • 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.

Analyzing the results, you can see that, even though having a hot water recirculating pump doesn’t save you money, it is quite a cheap deal. You will spend around $100 per year to have such a pump run inside your home.

Now, given that you save water worth $75, it is safe to say that a hot water recirculating pump is a good deal. After all, without one, you’d have to pay close to $200, while having to wait for cold water to heat up!

How Do You Install a Hot Water Recirculation Pump?

As you’ve seen in the review section, most, if not all hot water recirculation pumps can be installed very easily. For some, you will need just a wrench, while others may require a couple of other tools, depending on the pump type.

However, here is a basic guide on how to install a hot water recirculation pump. Make sure to refer to the user’s manual before taking our word for granted, to make sure that your model doesn’t require any additional or specific steps.

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.

To install your hot water recirculating pump, follow these steps:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. Finally, you can set up the pump via the timer.

As you can see, it takes only 11 steps to install your very own hot water recirculating pump!

Frequently Asked Questions

  1. Do I really need a hot water recirculating pump?
    Basically, if it takes more than 45 seconds or so for the water running down your faucet to get hot, then you have to strongly consider getting such a pump inside your household.
  2. Does a hot water recirculating pump take a lot of space?
    Not at all. These products are usually very small and installed either under your sink or near the water heater.
  3. How long does it take to install the hottest water recirculating pumps? It is a difficult process?
    As you’ve seen earlier in this article, the process is not difficult at all. You just have to make sure that you are disconnecting and connecting the right valves and water lines. In terms of time, it will take you a maximum of 2 – 3 hours to fully install a hot water recirculating pump.
  4. How to avoid and prevent corrosion in a hot water recirculating pump?
    Such pumps are usually affected by flow-accelerated corrosion. This can be a very costly problem – you should check the water pump for such issues regularly. The corrosion itself is caused by the water’s aggressive chemistry or excessive flow velocity. Because of this, the pipes get eroded by the water inside of them. The main parts that get affected by this issue are elbows, bends, and the tees around thin walls. In order to avoid and prevent corrosion, it is recommended that you choose a lower capacity hot water recirculating pump, as well as reduce the abrupt changes in pipe directions in your home’s plumbing.

Wrap Up

By now, finding the best hot water recirculating pump should not be an issue for you! After all, we’ve provided you with all of the information needed to make a wise choice when it comes to buying such a product.

On top of that, we’ve also looked into several hot water recirculating pump reviews and presented you with some of the best products currently available on the market. However, don’t hurry and keep in mind all of the things we’ve mentioned so far.
