A hot water recirculation pump is a system that pumps hot water to faucets quickly. Without one, it often takes quite some time for running water to become hot.  Considering it may take a full minute for hot water to arrive for a shower, it could mean that you waste 2.5 gallons of water per shower.  However, as with everything, there are always positives and negatives with this system too. Before we look at both the pros and cons of hot water recirculating pump, let’s learn a few more things about them!

How does a hot water recirculating pump work?

When you use a hot water recirculating pump, you get a continuous flow of hot water through the pipes. The water is already warm at the point of arrival, so there is no more wait or waste. While the systems may work differently, the main idea is that they keep the hot water circulating through the pipes. The water may end up back in the boiler or run through the cold water pipes, but overall, the best hot water recirculating pump will give you instant hot water whenever you need it.

Do Hot Water Recirculating Pumps Save Money?

If you wait for a minute to get hot water and you use low-flow fixtures, you waste about 1.5 gallons of water for a shower and about 2 gallons utilizing the kitchen sink. If you use regular fixtures, you dump down the drain about 2.5 gallons of water for every shower. A very conformist estimate per year leads to a person wasting about 5,000 gallons. It does not mean a lot of money, but it can mean a significant budget if you have a large home, a large family, and fixtures sitting more than 100 feet distance from the water source.

Do Hot Water Recirculating Pumps Save Water?

Yes, they can save a lot of water. If you think about a rough estimate of 4,000 gallons per person per year and you multiply it with the number of family members, you can easily understand why a hot water recirculating pump helps you reduce your water footprint tremendously.

Do Hot Water Recirculating Pumps Save Money on Electricity?

It all depends on the type of pump you get. The traditional ones usually consume more electricity than under sink hot water recirculating pumps. The answer here is that they won’t save you money if the utility bill is of concern, but they are still worth it as they are low-end electricity consumers overall.

How Much Does Hot Water Recirculation Pump Installation Cost?

It mostly depends on what type of system you choose for your home.

  • Under-sink hot water recirculating pump: it can cost zero dollars if you pick such a device and install it yourself. Your only concern here is to make sure you have a power source in the vicinity of the pump.
  • Traditional full recirculating hot water pumps need a professional plumber to take over the project.
  • Tankless water heaters with recirculating pumps also need a professional hand for installation and maintenance.

Pros and Cons of Hot Water Recirculating Pump

Cons of Hot Water Recirculating Pump

Let’s start with the cons, so you know what to expect before you decide on buying a hot water recirculating pump.

1. Noise

Some pumps can be noisy, particularly as they get older.

2. Using too much power

Even the most energy-efficient pumps will consume electricity and gas and maybe give your utility bills and unwanted boost. It is smart to install a timer, so the pump is not working at night or when you are not at home.

3. Potential heat losses

If the return pipes do not feature proper insulation, they allow heat to escape. In turn, it leads to energy and money waste. In other words, always make sure you correctly isolate the pipes and plumbing.

4. Corrosion

The elbows and bends of standard pipes are more prone to deterioration, and with a hot water recirculating pump, they may even rupture. Such damages can be costly to fix.

5. Cold water delays

Most of us waste our water by waiting for it to warm up. However, with a hot water recirculating pump installed, it is cold water you have to wait for, so that is a tradeoff.

6. Sensor valve costs

Hot water recirculating pumps do not last forever, even if they have long lives and warranties. Eventually, you will have to replace them. Some consumers report that you need to change the sensor valve every two years, so that also adds some costs worthy of factoring in your decision.

Pros of Hot Water Recirculating Pump

Now that we saw the cons – and some of them can put you off, granted, – let’s understand better why people are still using these systems and even look for the best hot water recirculating pump in the market to upgrade and replace the existing one every few years.

1. Instant access to hot water

Nothing is more frustrating than standing at the sink, waiting for warm water to wash hands or dishes. Frustration intensifies when you are an eco-conscious person that watches water wasting away while you wait for the shower to get warm. A hot water recirculating pump means instant hot water for any your needs.

2. Water conservation

In a typical household, we waste too much water every day just because the water is not warm enough. A hot water recirculating pump can conserve thousands of gallons of water per year, per fixture. When we live in a world where water is becoming scarce, hot water recirculating pumps become one of the sensible and reasonable answers to water conservation in the home and achieving zero-waste lives in the bathroom.

3. Affordability

A hot water recirculating pump is probably one of the smartest ways to reduce water use in a household. While you do need to calculate installation and maintenance costs, you also should know that some brands are incredibly affordable. If you install the pump yourself, you can have instant hot water in a matter of minutes for a couple of hundred dollars and no worries for years to come.

4. Advanced technologies

Most modern hot water recirculating pumps feature sensors and timers that add to their value for money in the long run. Moreover, some of the best such devices last for years with little to no maintenance, so even if the initial costs seemed high, you would have a reasonable rate of investment.

5. Timesavers

It might seem silly to think it’s a waste of time waiting for a minute or two for hot water, but if you consider how often you stand around waiting in a day, week or year, it is not that silly anymore. Especially if you have a large family to manage.

6. Easily available

You can find hot water recirculating pumps in almost any hardware store. Depending on the brand and model, they are accessible to all types of budgets. Most people buy them online, but if you want to see one for yourself, you will find it with no problems.

7. Straightforward installation

As we said before, the DIY types of under sink hot water recirculating pumps are a breeze when it comes to installation. Most of them come with detailed instructions, and you do not need a particular skillset to mount them to your existing water supply system.

8. Easy operation

It adds to the advanced technology we mentioned above on this list of pros. Just like installation, service is straightforward. Most hot water recirculating pumps come with automation. You can program the timers, or you can use the systems by merely pushing a button or two.

9. Come with renewable power sources integration

If your home runs with solar or wind energy, a hot water recirculating pump will fit in perfectly. Most of them work well with alternative energy and will save you even more resources and money if you install and operate them properly.

10. Residential and commercial applications

Whether you want a hot water recirculating pump for your home or your business, you can include them in your residential, commercial, and industrial plans. You need to pick the right make and model for your needs, but other than that, you are good to go!
