Types Of Best Hot Water Recirculating Pumps

Hot Water Recirculating Pumps1. Pump At The Water Heater

Placing a recirculating system at the water heater is very efficient because it enables you to get hot water much faster than not having the pump at all. This is especially true if your hot water heater is located on the other side of the house from your bathroom or kitchen. When this happens, you have to wait much longer to get water that is hot, which means you waste a lot of gallons as well. Having a pump at the water heater location, however, eliminates this problem and saves you a lot of money in the process.

2. Pump At A Point Of Use

Pumps at the point of use are attached to a certain faucet and only work with that particular faucet. Some smaller homes use point-of-use pumps because they are a fast and simple solution. They are also inexpensive and, therefore, you can place them in various locations around your house. Some people find these systems to be more useful than the systems that are attached to the water heater, which tend to be more expensive and more complex.

Timer/Aquastat-Driven Systems

A timer is one of the best investments you’ll ever make because once it is attached to the water heater, it enables the heater to work only at certain times of the day. This means that when the timer is off, only cold water will be available, but you’ll save a lot of money on your utility bill because you only get hot water at certain times. Indeed, the hot water heater isn’t making hot water 24 hours a day, which saves you a lot of money year after year.

Why Get A Hot Water Recirculation Pump?

When you turn on your faucet, the water has to travel through your plumbing system until it gets to the faucet itself, and when you need hot water, the system has to heat up the water first. Unless you want to wait a very long time to enjoy that nice, hot water, you’ll need a water recirculation pump. If you don’t have one of these pumps, the water in your pipes that didn’t make it to the faucet stays there once you turn it off, until the next time when it is pushed out by water from the water heater.

A circulating pump will return unused water back to the water heater instead of keeping it in the pipes. This not only allows the system to run more efficiently, thereby saving you a lot of money on your utility bill, but it also enables you to get hot water much faster. Therefore, you can consider one of these pumps the perfect way to get hot water on demand and let’s face it, that is important to most, if not all households.

What Is A Recirculation Pump?

Recirculation pumps are attached to a certain pipe and keep water circulating as long as the faucets are on; in other words, their main purpose is to keep hot water moving through the pipes so that when you turn on the faucet, the water is immediately available. Without one of these pumps, there will be more piping between the faucet and the water heater, which means it will take longer for the hot water to get to the faucet so that it can be utilized. These pumps are placed in strategic locations so that they do their job efficiently and safely every time.

Different Types Of Hot Water Recirculating Systems Available

Traditional Hot Water Recirculating Systems

Traditional hot water recirculating systems can be attached to either a specific faucet or the water heater itself. They are made to heat up the water quickly, so once you turn on the hot water faucet, you never have to wait long to get the hot water you need. This isn’t to say the hot water comes out immediately because it doesn’t; however, it usually comes out very quickly and gets to the faucet without you waiting a long time for it.

If the system you’re purchasing is without any special features, it is a traditional system, and these are the perfect pumps for homes and for many businesses.

Instant Hot Water Recirculating Systems

The instant type of recirculating systems will specifically state this aspect in its advertising. As soon as you turn on the hot water faucet, you get hot water immediately, mainly due to the way the pump is made and how it is installed. If you’ve ever seen a hot water tap in the kitchen that people use to make hot tea and other hot beverages, you’ve seen one of these systems.

On-Demand Hot Water Recirculating Systems

On-demand systems are systems that save space and water because they are usually very compact systems that don’t take up a lot of room. They provide endless, consistent, on-demand hot water that can be used for a variety of purposes. They are usually very energy efficient and simple to install, and they are often used in tankless hot water systems.

Hot Water Recirculation Pumps Buying Guide

  • Construction

Naturally, the construction of the unit is going to be an important consideration, so the higher the quality of materials, the more longevity the unit will have. Don’t buy a unit if the parts are made out of plastic or they look cheap but instead choose ones that have stainless-steel parts and ones that look like they are built to last.

  • Connection System

Many connection systems are ¾” NPT, which is normally the size and type that are recommended. When reading any descriptions for the products available, the type and size of the connection system are always listed, so it should be very easy to find a hot water pump with this feature. Online stores always have detailed descriptions of all of their products, which makes it easy to get the exact dimensions of all of the various parts of the product.

  • Pump Size And Flow Rate

The pump size automatically affects the flow rate, and the best recirculating pumps for hot water heaters have variable flow ranges, which means they automatically adjust depending on the usage. This means you never have to worry about the system having too much pressure, and it will always pump the right number of gallons per minute to accommodate your family. A nine-gallon-per-minute pump rate is ideal for most homes.

  • The Horsepower

The horsepower can range from 1/10 to 1/25, and many recirculating pumps have different horsepower speeds than this. Naturally, you’ll want one with the fastest horsepower because they will work a lot faster than the others, which means they are more efficient as well.

  • Temperature Settings

Most recirculating hot water pumps will give you a minimum and maximum fluid temperature, which are the amounts handled by the system. Normally, the range is roughly between 35ᵒF for the minimum and up to around 230ᵒF for the maximum. A wide range is good because it means that the system can handle a multitude of different water temperatures and still work proficiently.

  • Maintenance

The best way to check on the maintenance of a circulation pump is to read online reviews from people who have actually purchased and used the pump. Most of the online stores you’ll end up buying these systems from having real-life customer reviews, and they are the most reliable reviews you’re going to get. If you read enough of them, you can learn about the pros and cons of all of these systems, which can give you a great idea of which one you should purchase.

How To Install A Hot Water Recirculation Pump

Conclusion

There are many different types of hot water recirculation pumps, and they come with all types of features and in all different sizes and capacities. The pros and cons of these systems can be learned simply by doing some research online, but it is also good to start by ascertaining your home or office’s specific needs so that you don’t get a system that doesn’t meet those needs. After all, there is no need to purchase a large, powerful system and spend all that money if this isn’t what you need.

Fortunately, you can find out anything about the systems you’re considering purchasing with a little due diligence on your part, and you can save both time and a lot of money if you do this first.
