To help make sure that you are using as little energy as possible to get your hot water, you can program this device to shut off completely during inactive hours.

Thankfully, this particular model can pump up to nine gallons per minute, which is more than enough for a single-story home.

Finally, to help seal the deal and make this pump as effective as possible, it has an automatic sensor that activates when the water in the line gets below 85 degrees, and it shuts off when the temperature rises above 95 degrees.

6. SHURflo 4008-101-E65 3.0 Revolution Water Pump

Kicking off our list is the 4008-101 Water Pump from ShurFlo. This brand makes a lot of high-quality pumps, and most of them are designed for RV use, which makes it a great option for this list. In fact, we’ll be looking at a few different models from the company since they are so renowned for their expertise.

In fact, it comes with a two-year warranty to prove that point.

That being said, as with most RV pumps, moderation is always best. If you run the water excessively, it can cause the pump to overwork itself and shut down.

  • Delivers up to 55 PSI
  • Thermal protection
  • Mounting bracket included
  • Adjustable pressure switch

  • Self-priming pump
  • Activates at 25 PSI
  • Shuts off at 55 PSI
  • Internal bypass low-cycling

How to Choose The Best Hot Water Recirculating Pump

Since this pump can have such a profound effect on your home’s water usage, it’s crucial that you take the time to find the right model for you. Fortunately, there are not a lot of different components involved in a recirculating pump, meaning that if you pay attention to these different factors, it shouldn’t be too hard to find one that will work well in your household.

Timer

The biggest reason to get a best hot water recirculating pump like this is to not only get hot water instantly but to save money on your water bill. Unfortunately, some models will then increase your electric bill, making the whole thing a moot point. However, to help minimize the energy usage for your device, many of them come with a programmable timer. This enables you to pick times where you do not need hot water so that the system won’t turn on during those times. This helps ensure that you aren’t paying for something that you don’t need. The best time to have the system shut off would be at night when you and your family are sleeping.

Materials

With a device like this, you don’t want something that will have to be replaced on a regular basis. As such, you want a model that requires little maintenance and can be used for years on end without breaking down. To make sure that you get the best results possible you have to pay attention to the types of materials used in its construction. Many recirculating pumps are made with stainless steel to protect the components from rusting and corrosion, but not all of them are. If you get one with cast iron or plastic parts, for example, it may break down quicker. The trade-off here is that the unit will usually cost less up front, so it’s up to you to figure out if the initial cost is more important than longevity.

On Demand vs. Constant Recirculation

As we mentioned, one of the problems with some water pumps is that they move hot water through the system all of the time, meaning that you are spending as much energy to keep the water hot as you are saving by eliminating water waste. To make sure that you are as efficient as possible, you want a pump that comes with an automatic sensor. These usually work by activating the pump when the water reaches a certain temperature (such as 85 degrees), then shutting off when the desired heat is activated (such as 95 degrees). This type of pump will usually only add a negligible amount to your energy bill, making it a much better choice overall.

Tankless Water Heaters

Finally, the last consideration you have to make is whether or not you have a tankless heater. Many recirculating pumps do not have enough water pressure to activate such heaters, meaning that you either have to find one that does or skip the pump altogether. Unfortunately, getting a unit that works with a tankless heater is generally going to cost more, so it’s up to you to decide if the added investment is worth the convenience of hot water on demand.

Why Do I Need a Water Recirculating Pump?

In the end, if you are a person who hates having to wait for hot water, or if your system is remarkably slow at delivering it, then a recirculating pump can be a great option. Additionally, it may come in handy during colder seasons where you have to wait longer for hot water to arrive. This will not only ensure that you get better results, but it can help you save on utility bills by further reducing the amount of waste water you go through in a single season.

The other reason to get a best hot water recirculating pump is if you are worried about all of the water that goes down the drain while you wait for it to heat up. This device will significantly reduce your consumption and thereby save you money on your water bill. As long as you make sure that you aren’t using too much electricity to operate the system, you could wind up saving a lot over the long term.

Final Verdict

After looking through these different pumps, we have to say that the Watts Hot Water Pump is the best hot water recirculating pump. We like how easy it is to install as well as the benefits and features that it offers. Not only can you save a ton of money per year by wasting less water, but the system itself is energy efficient and easy to use. Overall, you get a lot more from this model than you do with others in the same category.
