What you need to know about hot water circulation pumps

Hot water is a modern convenience that most of us don’t usually think about. However, if you’ve ever had to wait a few minutes for the water coming out of the faucet to warm up, you might be interested in learning more about hot water circulation pumps. Instead of just sending hot water to the tap when you ask for it, these types of systems ensure that there is always a steady supply of hot water ready to flow immediately to the tap.

While waiting a few minutes for hot water is more of an inconvenience than anything else, it can also be a waste. Unless you collect that unused cold water in a bucket for reuse in the garden or elsewhere in your home, it all goes straight down the drain. With a hot water circulation pump, cold water in your pipes returns to the water heater, bringing fresh hot water to the tap so it’s ready when you need it.

Due to frequent drought conditions and limited water in California, the stateBuilding Energy Saving Standardsnow requires all new homes to include a hot water circulation pump if they have faucets more than 50 feet from the water heater. The purpose of this policy is to avoid wasting water while the homeowner waits for hot water to arrive. Even if your home is older and doesn’t have to follow this new rule, you can still make the switch. Here’s what you need to know.

Why does cold water come out of a hot tap?

When you have separate handles for hot and cold water, you expect hot water to come out when you turn the hot handle and vice versa. So why do you get a spurt of cold water from your hot water faucet before the water heats up? The answer is that the water left in the pipes has cooled over time.

When you turn on the hot water tap the last time you need it, the water will turn off as soon as you turn off the tap. However, hot water must go from the water heater to the tap for you to use it. When you turn off the tap, there is still plenty of hot water flowing through. Once the faucet is turned off, there’s nowhere to direct that hot water, so it sits there in your pipes. Over time, it will lose heat, leaving cold water in your hot water pipes.

Then, the next time you turn on the hot water, the cold water from the hose must escape before the hot water can pass. It’s the cold water you feel the first minute after turning on the tap. When the hot water has had enough time to flow from the heater to the faucet, forcing out all the cold water along the way will give you the hot water you need. The longer the distance between the water heater and the tap, the longer it takes for hot water to reach you and the more water you will waste in the process.

Hot water circulation pump design

To minimize water wastage while waiting for hot water, you can install a circulation pump on your water heater. These pumps return unused hot water to your water heater to maintain its temperature while directing fresh hot water to your faucet so you don’t have to wait for it to heat up. The hot water circulation pump often falls intotwo main categories.

Complete circulation pump system

In this type of system, your plumber will install additional hot water pipes in your home. These pipes can then return unused hot water to the water heater. When the cooled hot water returns to the water heater, the new hot water can be replaced so it’s always ready to use when you need it. Hot water circulates in a continuous loop throughout your system for a steady supply of hot water, minimizing wait times and wasting your water.

If you’re concerned about how this constant activity might affect your energy costs to heat your water, there’s no need. Although the system is able to operate continuously, it is not always possible to do so. Most hot water circulation pumps are equipped with a sensor or timer to regulate operation. The sensor can detect the temperature of hot water in the pipeline, only running the circulation pump when the temperature drops below a specified level. This way the water will not continue to circulate once the water is hot, which will usually shut itself off after a complete cycle.

Timers give you more control over when your system is operational. For example, you can schedule your system to turn off automatically after a specific time in the evening so it won’t run while you sleep. You can also schedule the system to turn off when you’re at work or on vacation out of town.

Even if the hot water circulation pump you choose doesn’t have a sensor or timer, your plumber can easily install one for you. This way you get all the benefits of better control of your system without having to choose an entirely new pump system.

During installation, your plumber will need to run additional pipes throughout your home to return unused hot water to the water heater. This can significantly increase your installation costs, especially if the pipes in your home are hard to find. If you don’t want to pass up the extra cost or if the installation is too complicated, you have another option.

Circulation pump comfort system

To avoid having to install new pipes, you can choose a hot water circulation pump to send unused water back to your water heater through your chilled water pipes instead of going through a separate piping system. . This option is much more economical and easier to install, making this style of system accessible to more homeowners. However, you will still get the benefits of fast hot water when you need it.

However, the comfort system has a major drawback. Since hot water will return to the water heater through the cold water lines, the water coming out of the cold water faucet will initially be hotter than usual. It may also take a few minutes for the water to get really cold. In most cases, this won’t be much of a problem, as hot water is ideal for many applications around the home, such as cleaning and cooking. However, if you use your tap to provide drinking water, you may need to wait until the water is cold enough to feel good.

You can get around this problem when you know you’ll need cold water by temporarily turning off the pump. This method is particularly effective in summer. Because the weather is warmer this time of year, you won’t need to run the pump as often to get hot water, because the water already in the pipes will stay hot longer.

Save water with a hot water circulation pump

While the most obvious benefit of a hot water circulation pump is that you’ll be able to get hot water almost instantly from every sink in your home, you’ll also save a lot of water. Because there are so many factors involved in calculating water savings, it is difficult to quantify exactly how much water you will save, although some estimates give figures as high as15,000 gallons per year. However, several factors can increase or decrease your savings.

For starters, the size of your pipe plays an important role. Larger diameter pipes can hold more water than smaller ones, so you’ll get the biggest savings if you have larger diameter pipes. The distance between your water heater and your faucet is also important. If your hot water previously had to travel a long distance to reach the tap, your savings will be greater if your tap is closer to the water heater.

Choose your hot water circulation pump system

When choosing a hot water circulation pump, your first decision is whether you want to use a full recirculation system or a comfort control system. Your budget and the layout of your home will be among the most important factors in this decision. If the plumbers have easy access to your plumbing and you can afford a little more, then a full recirculation system will give you the greatest benefit without the inconvenience. The purpose is to reheat cold water on the return. To save money, time and complexity, an accreditation system may be a better choice for you.

Once you have decided on the type of system you like, your next step is to choose a sensor or timer to control it. If you don’t want to worry about programming your system, a sensor can do the work for you by monitoring the water temperature in your pipes. However, to maximize the efficiency of your system, you will want to have the best possible control over when your system is operational. For this you will need a timer.

Mechanical timer, simple to set up and even easier to set up. However, you may be limited in the amount of detail you can get with your time. If your schedule changes from day to day, an electronic timer will give you more flexibility. You can usually schedule certain scenarios to accommodate changes in your daily schedule, such as working days to weekends, or if your schedule doesn’t follow a typical work week.

Other Reviews

It’s also a good idea to insulate your hot water pipes, both leading to your faucet and back to the water heater. This will help trap the heat inside and prevent it from spreading through the tube wall over time. With good insulation, the water stays hotter longer, reducing the number of times you have to run the pump throughout the day to keep the water in the pipes hot. This can result in significant energy savings over time.

California is notorious for its hard water, and if you don’t install a water softener in your home, minerals in the water can wreak havoc on your hot water circulation pump. To help it last as long as possible, look for pumps made of stainless steel to reduce the risk of corrosion and prevent the formation of lime deposits.

You should also be aware of the size of the air inlets. When calcium deposits form in pipes, they can shrink these holes over time. The larger the gap, the easier it is for water to continue flowing. Even with a little buildup, you’ll still have plenty of water, saving you time between maintenance visits.

This Old House plumbing and heating expert Richard Trethewey explains how a recirculation line can save energy, money, and time. (See steps below.)

-http://bit.ly/SubscribeThisOldHouse

Steps for How to Get Hot Water with a Recirculating Pump:

1. A recirculation line is a separate water pipe that runs off the hot-water line from the farthest plumbing fixture back to the water heater.

2. A pump at the water heater moves hot water through the recirculation line. Any cold water in the recirculation line is returned to the heater.

3. A check valve must be installed in the line to ensure hot water only goes in one direction.

4. An aqua-stat is mounted to the hot-water pipe. When it senses that hot water is returning to the heater, it shuts off the pump.

5. A timer is used to ensure that the system isn’t maintaining the recirculation line when you’re away at work or sleeping.

6. All-in-one pumps are available that have the aqua-stat and timer built into them.

7. Pumps and fittings can be used to push cold water in the hot-water pipe into the cold-water line until it senses that hot water has finally arrived from the heater.
