Grundfos vs Taco Circulator Pumps

Grundfos vs Taco Circulator Pumps – Which Circulators Are Better?

Circulator pumps are responsible for taking care of many activities throughout the house, like providing a constant water supply to different outlets in different areas.

While looking for one to buy, you’ll encounter many offers available, sometimes too many that it’s difficult to pick just one.

In a sea of options, two brands come to mind, and those are Taco VS. Grundfos Pumps provided by these brands are outstanding, with many highlights that would make them our favorites quickly.

Of course, we still have to pick one, and that’s the purpose of this article. Here, we’ll cover the features provided by the circulator pumps from each company, hoping we can establish a sole winner by the end of this read.

So, without anything else to add, let’s begin!

Grundfos vs Taco Circulator Pumps 202` Comparison

Grundfos Circulator Pumps

Grundfos is a brand that produces high-quality circulator pumps. Their catalog has many units, and you can often find plenty of them in online discussions, as there’s a lot of people that prefer this company above the others.

But, are Grundfos pumps really that good? Well, they are, but they’re far from perfect too.

For reference, we’re reviewing the 59896155 and 59896341 Grundfos units.


Grundfos circulator pumps share most of the same features regardless of the model.

For example, the 59896341 and 59896155 models have a corrosion-resistant impeller, as well as the cast-iron housing.

Such a design makes the units long-lasting, resisting the abuse of continuous use.

However, previous customers recommend precaution for people looking to buy one of these units.

In many cases, some parts detached from the circulator pumps during transport, which is the last thing you’d expect. Once it arrives, check the package to confirm everything’s good.


Due to the quality of the parts used for their construction, the Grundfos circulator pumps are capable of working well while resisting against issues like corrosion.

Because of that, homeowners would be able to put the pumps to continuous heavy-duty use.

Another pleasant benefit of having a unit like the Grundfos 59896341 is that it’ll perform quietly.

If you’re looking for a pump that delivers hot water almost instantly, this brand has plenty of offers available that would satisfy those demands.

Is It User-Friendly?

The process to install the 59896341 model, and many other units from Grundfos is pretty easy.

Previous customers would also agree that they didn’t face an issue they couldn’t solve quickly.

Still, depending on the application of the pump, you may need to do some extra work.

For instance, the Grundfos 59896155 pump could require additional pipes installed in the house, which is expensive and requires much more effort.

Unfortunately, Grundfos circulator pumps often have many issues during their installation.

Taco Circulator Pumps

The 007 Series from Taco, featuring Cartridge Circulator units, is among the preferred by many people.

When compared to other hydronic circulator devices, there aren’t many capable of performing as well as them.

It’s all possible due to a combination of high-quality parts and high power capacity.

Another reason why circulators produced by Taco are worth the money is because of their self-maintenance.

In cases like the 007 models, the systems feature a self-lubricating design that renders the units almost maintenance-free.

There are many more reasons to like Taco’s circulator pumps. Let’s find out what those reasons are.


Taco’s circulator pumps like the 007 Series have a compact design. Mostly made with cast-iron, the construction of these units is good, putting up an impeccable performance throughout.

There’s no mechanical seal included, and the number of tasks these circulator pumps cover is high.

For instance, you can use them for hydronic heating, radiant heating, indirect water heating, and many other purposes.

Overall, Taco offers efficient home equipment capable of taking care of the domestic water systems, providing the family with a constant flow of water.


Taco circulator pumps are surprisingly quiet while active. Not only that, but they’re also efficient, saving a lot of energy.

The direct drive-low system allows for less power consumption, making the units work better without wasting energy.

The motors are great too. Working at 3,250 RPM, with an HP capacity of 1/25, the pumps meet most of the expectations by operating without interference.

Is It User-Friendly?

While Taco’s circulator pumps are great, you may struggle to install units like the 007 Series.

Of course, whether it takes a lot of time or not depends on your knowledge handling these devices. Professional services may save you a lot of trouble.

Once installed, though, the pumps will work properly for many years. In some cases, the durability of the units covers more than a decade.

Also, while maintenance is necessary periodically, you don’t really have to put too much effort to do it.

The pumps feature automated mechanisms that keep their systems working continuously.

Grundfos Circulator Pumps You Can Buy

Grundfos has offered many incredible circulator pumps over the year. The following three picks are among the most reliable models produced by this brand.

1. Grundfos 59896341 UPS15-58FC Circulator Pump

This circulator pump features iron housing, providing security for the internal mechanism as it operates. Such a construction design keeps external elements from interfering with the motor’s performance.

The motor offers three speeds, which are low, medium, and high. Customers have the option to set up the circulator pump to work just as they need.

When the device is operating, the wet rotor design allows it to operate quietly. This circulator pump is quite versatile.

You can rest assured this product will work well with all of those appliances.

For the most part, this device is easy to install. If you set it up for a water heater, you may be able to do it quickly.

However, for other applications, perhaps it may be necessary to get some pipes extensions to make the right connections.

The Grundfos 59896341 is a circulator pump that displays quality in every one of its parts.

Besides the cast-iron housing, the ceramic shaft and radial bearings are two other design choices worth mentioning.

Additionally, there’s a carbon axial bearing and the stainless steel rotor. We also liked the impeller design, as it resists pretty well against corrosion.

Customers can expect this circulator pump to last for more than a decade. It’s small, but no other pump works as well as this one.

The only thing that would make this product better would be the addition of a timer. Now, the circulator pumps may not have it, but you can attach one by yourself if needed.

2. Grundfos 52722512 3-Speed Circulator Pump

The following circulator pump isn’t that different from the one we reviewed before. This one features the same 3-Speeds motor, which offers low, medium, and high modes.

Also, this product is versatile, as it allows you to install it for a variety of applications.

Setting up the circulator pump is a straightforward process. The instructions provided are generic, although they may be misleading in some parts.

For example, there’s a section that recommends removing the check valve, which is not really necessary, as you can leave it there anyway.

By including a built-in flow check, Grundfos ensures customers won’t have to buy an in-line check valve to make this pump work.

On the contrary, everything needed comes with the purchase, saving you some money in the process.

The circulator pump is suitable for closed-loop systems that operate with medium or high flow rates.

While operating, the thermal protection included maintains the motor secure, guaranteeing the pump’s durability and performance.

True to Grundfos’ style, this unit works quietly too. You can use it for radiant heat, hydronic heat, fan coil heat, and many other appliances.

Just as this circulator pump is powerful, it’s very user-friendly too. The motor consumes low energy, which reduces the energy bills and the risks of issues such as overheating.

If you’re looking for a replacement circulator pump, then this one is probably everything you need. It’s a quiet device that doesn’t weigh a lot, and it’s also far better than most standard pumps too.


  • 1/6 horsepower motor works for different applications
  • Three speeds available: high, medium, and low
  • Easy to install, consumes low energy, works quietly, and doesn’t require maintenance
  • Built-in protection to guarantee the motor’s performance and durability

3. Grundfos UP26-64F 52722330 Circulation Pump

Unlike the other two products, the UP26-64F model actually features a single-speed motor. It may be less powerful, but that also comes with many benefits.

One of them is less energy consumption, and another one is that the unit requires no maintenance at all.

The purpose of this pump is to back medium and high flow in closed-loop heating appliances, such as hydronic heating.

Additionally, it supports radiant heat, fan coils, and snow melting, among others. So, as you can see, this circulator pump is equally as capable as the other two.

Despite being a little different, the unit shares some similarities with previous Grundfos pumps.

For instance, this product also includes thermal protection. As we’ve learned by now, this automatic resetting feature protects the motor, allowing the pump to last for a long time.

You shouldn’t have any major issues installing this device. Nonetheless, you may encounter some issues in other areas.

One of the most noticeable flaws of this circulator pump is that it isn’t as quiet as other models. On more than one occasion, you’ll notice the sound it makes in the background.

Also, keep in mind that this product doesn’t have a built-in check valve. Previous customers showed disappointment due to the lack of said valve, but the manufacturer is pretty clear about it.

Other than that, you should expect nothing but good things after purchasing this product.

The order arrives pretty fast, and the customer service is outstanding if you ever have any concerns.


  • Single-speed motor suitable for several applications
  • Built-in protection for the motor guarantees its durability
  • Includes gaskets
  • Low energy consumption

Before going all-in with this product, you should know that it doesn’t include mating flanges.

They are necessary, which means that you’d have to get it separately. Even then, it’s an extra cost that’s totally worth it.

Additionally, this pump is compatible with fan coils, heat exchangers, and many other appliances too.

Something that may be surprising about this pump is that it’s the perfect replacement for several other models.

The universal flange to flange design and orientation allows customers to set it up and replace old pumps that don’t work anymore.

Despite being a compact circulator pump, the 0011-F4 unit offered by taco is suitable for high-efficiency jobs.

The company’s catalog is pretty big, providing alternatives in case you’re not a fan of one of their products.

Better yet, Taco’s pumps are very user-friendly. Although it’d be better to hire an expert, homeowners with DIY skills will probably know how to set the units by themselves.

Grundfos, on the other hand, will show some frustrating issues from the moment you try to set up the pumps.

In most cases, you’ll end up spending more money in extra parts because the unit won’t work without them. These pumps require a lot of accommodation that demand effort too.

On the bright side, Grundfos circulator pumps will most likely never give you any problem after installing them.
