Buyer’s Guide

Buying a hot water pump isn’t like buying a new gadget for the house. A lot of things need to be kept in mind to select the best hot water recirculating pump. Although there are plenty of options in the market, most consumers are totally lost about the features.

In this guide, we’ll walk you through the process of selecting the best hot water recirculating pump for your home.

Build Quality

First and foremost, you have to make sure that the pump has a superior quality build. The better the build, the longer a pump will last. If you get a cheaper pump with a poor-quality build, it would only last for a year or two.

Why not spend a few extra bucks to get a pump that could last for decades? Make sure that the pump is made of high-quality material and will be able to stand the test of time.

Timer

While some pumps have in-build timers, this is a feature that you won’t find in all models. If you’d like to program the operational time of the water pump, you should get one with a timer.

You can program the settings to provide hot water to the faucets only when there’s a peak in use. Basically, you can schedule it to turn on and off. Even if you initially buy a water pump that does not have a built-in timer, you can install one later on.

Temperature

The minimum and maximum temperatures differ from one pump to the other. When you’re buying a hot water recirculating pump, make sure that it comes with a wireless remote.

Having a remote makes it easier to adjust the temperature without manually dealing with the pump.

Housing Material

As you can see, most pumps in your review have a cast iron housing. Depending on the material used for housing, the pump is suitable for different things.

For instance, in the case of cast iron housing, the pump isn’t suitable for potable water as iron can rust the system. Instead, you can opt for a recirculating pump with aluminum housing.

Connection System

When using traditional systems, there are mostly just three main connection points. These are the discharge valve, hot water supply, and cold water supply.

Since these points will always be under pressure and have to bear high temperature, make sure that you find the right gaskets and fittings for them. Before you place an order for the best hot water recirculating pump, you should read its description properly and decide if it fits your connection type.

Price

Last but not least, you must factor the price too. If you’re looking for a budget-friendly option, we have those on our list too. If you have some extra money to spend, you can get a pump with additional features such as a built-in timer.

Also, check the product warranty. Although manufacturers normally give a 1-year warranty, some of them may also offer a longer warranty of three or more years.

Benefits of Hot Water Recirculating Pumps

You’d be surprised to know how much difference a small recirculating pump can make. Although there are many pros and cons of hot water circulating pump, it’s the pros that take the win, so we’ll discuss some of them below.

Constant Hot Water Supply

Have you ever walked into the bathroom early on a winter morning and washed your hands in the sink? The water is so cold for the first few minutes that it can wake you up from the deepest slumber. Even the hot water tap gives cold water initially.

If you have the best under sink hot water recirculating pump installed in your home, this won’t be a problem anymore. You’ll have a constant supply of hot water as soon as you turn on the faucet.

Saves Water

As mentioned in our review, most manufacturers boast about the amount of water you can save while using the hot water recirculating pumps made by them. Their claims are very true.

Think of it this way: in the situation mentioned above, you’ll keep the water running for a few minutes until it turns hot. All that water goes to waste. Now, do this every day, and you’ll be wasting gallons of water annually.

On the contrary, if you have a hot water recirculating pump in your home, you’ll get hot water instantly. So, you don’t have to wait for the water to get hot. What does this do? It saves all the water that you previously wasted.

Thus, you can end up saving thousands of gallons of water every year. Along with being good for the environment, this is also good for your conscience if you often feel guilty about wasting so much water but aren’t brave enough to wash your face with cold water in the morning.

Lower Bills

Another benefit of using a hot water recirculating pump is that you’ll have to pay lower utility bills. If the water is left running for too long, all of it will be charged on the bill, and you’ll have to pay much more money.

In contrast, when you install a pump in the house, it will save water, thus, saving money too.

Modern Technology

A common reason why most people avoid using hot water pumps is that they think the pumps will take more energy and end in higher bills. There’s a misconception that since hot water pumps are always sending water in a loop, they consume energy constantly.

Fortunately, this isn’t the case as most hot water recirculating pumps come with modern fitted technology. They have sensors or timers that shit off the pumps when not in use. So, once the water has completed a round, the pump will automatically shut off to save energy.

If you choose a pump with a timer, you can simply turn it off when it’s not in use. For example, if you’re going on a vacation or it’s the summer season, you can turn it off to save energy.

Compatible with Renewable Energy Sources

If you use solar heating in your home, a hot water recirculating pump will easily integrate into the system.

This is a great way to save energy and money. Make sure to get help from a professional when doing so. When done right, a hot water pump system integrated into solar or wind heating can save you a lot of money.

Ease of Installation

While it’s hard to install most apparatus at home yourself, it’s pretty simple to get the hot water recirculating pump ready for action. All the pumps mentioned in our review come with simple instructions that you can follow yourself and get the pumps working in just an hour or two.

Firstly, this is good news for people who like to do DIY tasks around the house. Secondly, it’s a great way to save labor costs that you’d otherwise have to spend on a professional for installation. Instead, you can treat yourself to a beer and some chips after you’re done installing the pump successfully.

What is Hot Water Recirculating Pump?

A hot water recirculating pump provides hot water on demand. It is installed on the water heater and sends hot water that is not used back to the heater. Thus, you no longer have to bear cold water before hot water starts coming; a hot water recirculating pump instantly brings warm water to the faucets.

Best Water Recirculating Pump

Generally, there are two types of water pumps, categorized according to their way of functioning.

Full Recirculating Hot Water Pump

Before we explain how the pump works, we need to discuss why the water gets cold. When you turn the faucet on, water is brought to it. The unused water stays in the faucet and gets cold. So, the next time you turn on the faucet, the cold water comes out first, followed by the hot water.

If a full recirculating hot water pump is in place, it will draw the unused hot water back to the water heater, so the water does not remain in the pipe, getting cold. As a result, you get hot water on demand.

Some of you might be wondering that if the water is constantly going back and forth from the faucet to the water heater, it might increase your energy cost. Actually, it’s not the case. This loop of water recirculating through the system does not have an effect on the energy costs, so you don’t have to worry about that.

Most pumps have sensors in them. After a loop is complete, the pump will shut off on its own. Similarly, some pumps also have timers. You can program the timers yourself, scheduling them to shut off when not in use.

Although this type of pump is common and used by most people, it’s not suitable for every home. If it is difficult to add a full recirculating hot water pump in your house, worry not, as there is another type too.

Comfort System Recirculating Pump

If your home’s plumbing design does not allow the installation of the first kind of water heating, then you can go with this option. In this system, the pump sends water back to the heater using the existing pipes.

This option is pretty suitable for homes where the water source is far from the destination. For instance, if the water in your kitchen faucet comes from a distant source, this pump system will make it easier to get hot water instantly.

However, this pump system does have some flaws. Since it uses the existing pipes, there’s a possibility of the hot and cold water mixing. So, sometimes, you may have to bear lukewarm or slightly colder water for a few seconds when you turn the faucet on.

If you cannot decide which option is the best for your home, you should consult a professional. They’ll tell you about the best and more economical options.

Overall, a hot water recirculating pump is a blessing for people who have been startled way too many times by cold water early in the morning.

With a recirculating pump, you’ll save money and water both. So, if you want to do your pocket and the environment a favor, it’s high time you start looking for the best recirculating hot water pump. Our 10 best hot water recirculating pumps review can surely make the decision easier.

How does a Hot Water Recirculating Pump work?

A hot water recirculating pump can work in one of the two ways: demand-controlled and gravity-led. We’ll discuss both these methods in detail to give you an idea of how hot water travels through the pipes and to the faucets in your house.

Hot Water Recirculating Pump work

Demand-Controlled Pump

As the name implies, this kind of circulation pump works on demand. Thus, when someone turns on a faucet, a sensor is activated, which turns on the circulation pump.

The pump sends the unused water back to the water heater. When the water has returned to the heater, the sensor alerts the pump to shut off again.

So, there’s no extra usage of energy as the pump shuts off after its work is done. Usually, you’ll see these systems in place as they are economical and use less energy. A tiny shortcoming is that they are slower than the gravity-led systems.

kind of circulation pump works

However, they help you save water and money so you can make the tradeoff if you like.

Gravity-Led

In a gravity-led system, water is recirculating constantly, so the system is on 24 hours a day. Firstly, hot water goes to the top of the circulation pump.

On the contrary, the colder water sinks down, being denser. There’s a check valve, which ensures that the water in the heater does not go to the return line.

The colder water at the bottom is heated and goes to the supply lines for hot water. Thus, the process begins again and continues continuously.

This system is suitable for instances in which the water heater is present under the faucet that is supposed to get the hot water. It’s quicker than the system mentioned above and is suitable for bathtubs and sinks.

Frequently Asked Questions

Whether you’re showering or doing the dishes, you’d want to wait for hot water to come, right? While you do this, you’re wasting up to two gallons of water. All of this adds up in your utility bills.

However, when you install a recirculating water pump, it will instantly give you hot water, so you won’t be wasting that initial cold water. As a result, your water bill will be lower, and you’ll end up saving a lot of money.

It might not seem like much right now, but once you add the cost, you’ll notice a significant difference.

The hot water recirculating pump for tankless water heater for your home can be very different from the one for someone else’s. It is up to you to make the right choice for your home based on the plumbing setting and your budget.

If you’re confused about which recirculating pump to buy for your home, you can consult our buyer’s guide given above.

Depending on the type of hot water recirculating pump you’re getting installed, the cost can differ. For instance, if you get an under-sink pump, it won’t cost you anything. You can simply follow the instructions that come with the product and install it yourself.

If you want a full circulating hot water pump, you’ll need the services of a professional because it’s tricky business. Lastly, you’ll also need a professional to install recirculating pumps with water heaters.

While working, any hot water circulating pump is bound to make a noise, but you must choose which makes the least noise, or it would be very bothersome. For example, we have many options in our review with the noise production of fewer than 30 decibels.

Nowadays, hot water recirculating pumps come with advanced features for easy control. You can buy one that can be controlled with a remote so that you don’t manually have to program it every time.

Most of the time, you can actually ‘hear’ the pump working as it will make a humming noise. Also, the pump may be vibrating. When you touch it, the pump must be slightly hot.

However, it shouldn’t be too hot as that’s a sign of something being wrong.

Even if you buy the best hot water recirculating pump, it will give up on you after some years. However, these pumps normally last for over a decade.

So, the purchase of a few hundred dollars can give you hot water and help you save water for up to 15 years, on average.

This is nothing to worry about as you can get a timer installed in your existing recirculation system. Just get in touch with a professional, and they’ll sort it out for you.

Conclusion

Overall, buying a hot water recirculating pump is an investment for your future. Along with helping you save water and money, these pumps can last for up to 15 years, thus, being economical.

In this article, we mentioned the 10 best hot water recirculating pumps and then discussed the criteria for buying the best one for your needs.
