You are heating the water quickly but wasting more water downthe drain and waiting longer for hot water.

We love tankless water heaters because they are more energy efficient, youwill never run out of hot water and they take up lessspace.

But in order to get hot water faster without wasting water down the drain youneed a circulation system. One that returns the cold water in the hot waterline to the water heater and one that has a high speed pump to move the waterfaster than just water pressure alone can.

And it needs to be a system that does not operate continuously and that does not keep your waterlines hot unless there is a demand for hot water .

The system you need is WaterQuick Tankless -the only hot water circulation system specifically designed for tankless waterheaters.

Hot Water Circulating Pump Guides And Reviews

The hot water circulating pump article provides guidance and review about different types, qualities, durabilities, and prices. Hot water circulating pump is a pump used to circulate the hot water in a closed circuit. It is mainly used in domestic water systems to avoid the water cooling. The water in the hot water system gets cooled down when not in usage for a long time.

The cold water gets accumulated near the output of the domestic water supply system. When we turn the water heating system, the accumulated cold water comes through the discharge. Hot water flows only after the accumulated cold water is transferred. The domestic water supply system requires sufficient time before providing the hot water output.

The cold water accumulation also leads to the wastage of water. In order to avoid the time lag and water wastage, a pump can be used to circulate the hot water in the system. This pump circulates a small quantity of hot water in the system continuously and hot water is made available instantly on turning the system. The hot water flows without any delay or lag, and water wastage is avoided. These pumps are utmost required in places with minimal water resources.

Should You Get A Hot Water Recirculation Pump

The pump will cost you $200 to install, $5.50-$32 to operate, will waste $160-$400 per year and will save you $4-$50 on your water bill. This gives you a negative return on investment , so it certainly doesn’t make sense from a cost saving or environmental perspective. But don’t take my word for it, there are actual case studies out there with empirical data.

The reason for installing a hot water circulation pump is pure convenience. If you can’t stand waiting a minute for hot water to emerge from the faucet and the operating cost is of no concern to you, then this is the solution for you.

How Much Does A Hot Water Recirculation Pump Cost

The price tag of a hot water recirculation pump is around $200 and most can be installed by the consumer but some require a plumber. In addition to this fixed cost, there are two variable costs to consider, the energy used by the pump, and the additional water heating required. The 25 Watt pump would use 219 kWh per year, costing about $32 . Many models feature timers so that they only run during set times of the day. Setting the pump timer to run two hours in the morning and two hours at night would cut the electricity use down to 36 kWh, or $5.50 per year.

Next we need to estimate the heat loss from the pipe as the hot water is circulated. Assuming that your hot water is 120°F and the air surrounding the pipe is 52°F you will lose 45 Btu per hour per foot. If you use the 125-foot assumption, this means you will lose 49,275,000 Btu, while using my 50 foot assumption you would only lose 19,710,000 Btu. One therm, the common unit of measure for natural gas, in the US is equivalent to 100,000 Btu, so you will burn through an extra 493 therms , costing you an extra $400 per year .

Why To Get A Hot Water Recirculating Pump

According to the National Resources Defense Council , studies suggest that over 10 percent of all the hot water drawn for showering in a typical single-family home is wasted waiting for hot water to arrive.

Much of the water sitting in those pipes was once heated. Without a recirculating pump, its left in the pipes to cool. Thats a lot of water, energy and money down the drain.

How much money does a hot water recirculating pump really save? While it can save some, its mostly for convenience. In 12 months, they can save you roughly $120, says Griccino.

A recirculating pump is relatively affordable. So even if you save less than $120, it can still pay off quickly. The time saved might be enough to justify the initial cost, even without a major reduction in utility bills.

To save more water, combine a hot water recirculating pump with water-efficient appliances and fixtures. A dual-flush toilet and efficient shower head go a long way toward cutting utility bills.

Why Cold Water Comes Out Of A Hot Water Tap

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

When you operated the hot water tap the last time you needed it, the water shuts off as soon as you turn off the tap. However, the hot water had to travel from your water heater to the faucet for you to use. When you turned the tap off, there was still plenty of hot water in transit. With the faucet turned off, there is nowhere for that hot water to go, so it just sits there in your pipes. Over time, it will gradually lose its heat, leaving cold water behind in your hot water pipes.

Then, the next time you turn on the hot water, that cold water in the pipes has to make its way out before fresh hot water can come through. This is the cold water that you feel for the first minute or so after turning on the tap. Once the hot water has had enough time to make its way from the water heater to the faucet, forcing all of the cold water out along the way, youll get the hot water you need. The farther the distance between your water heater and faucet, the longer it will take for the hot water to reach you, and the more water you will waste in the process.

How Do Circulation Pumps Work

How To Install a Hot Water Circulation Pump on a Tankless Water Heater

The great thing about hot water recirculating pumps is that they allow you to enjoy comfortable water temperatures instantly from your faucet. Its there when you need and it is also a more efficient way of conserving water. Normally water runs from the water heater through the pipes and out the tap, once the tap is turned off the water sits in the pipes and cools which results in the sit and wait for hot water. What the circulation pump does force a small amount of hot water to continually flow through the pipes starting at the water heater traveling to the farthest fixture and then traveling back. Therefore hot water is always in the pipes and water does not get wasted. Keeping increase in heat in the piping system also increases the pressure within the system.

After that, connect this 1/2 inch supply line to the hot water angle valve.

Full Recirculating Pump System

In this type of system, your plumber will install additional hot water pipes in your home. These pipes can then return the unused hot water to the water heater. As the cooling hot water makes its way back to the water heater, new hot water can take its place so that it is always ready to go when you need it. The hot water flows through a continuous loop throughout your system so that there is a steady supply of hot water, minimizing your wait time and water waste.

If you are concerned about how this constant operation might affect your energy costs for heating the water, there is no need to be. While the system is capable of running continuously, it doesnt always do this. Most hot water recirculating pumps come with sensors or timers to regulate operation. Sensors can detect the temperature of the hot water in the pipe, only running the recirculation pump when the temperature drops below a specified level. This way, the water wont keep circulating when the water is already warm, typically stopping itself after one complete cycle.

Timers give you even greater control over when your system operates. For example, you can program your system to automatically turn off after a specified time in the evening so that it isnt running while you are sleeping. You can also program the schedule to turn the system off when you are at work or go out of town on vacation.

What Is A Recirculating Pump

Recirculation pumps are commonly-used centrifugal pumps. The main function of this pump is to always ensure that hot water is available as close to the consumption point as possible in plumbing applications. This helps considerably to reduce water waste. The circulation pump is a class of pump used to move gases, liquids, or semi-liquid material in a closed circuit. Since this pump only circulates liquid within the closed-circuit the effort required to work this machine is significantly less than other pumps.

A little history on these pumps – when they were first installed in homes they would run 24 hours a day or would have a timer to operate at times that you could anticipate the hot water. Between jobs, families, athletics or school there is really no routine time that you can be sure you will be there when the hot water is. Eventually, the technology in hot water circulation pumps improved to offer several different options such as a push-button on-demand or there is also an occupancy sensor that triggers the pump. Limiting the amount of time the pump operates will save you money.

Advantages Of Installing A Circulation Pump

Hot water circulation pumps have been around for years. Many high-end hotels and restaurants have provided on-demand hot water to their guests as a standard convenience. However, recently more homeowners are beginning to take advantage of the many benefits a circulation pump can provide.

Here are a few of the advantages:

Convenience: A circulation pump delivers hot water almost immediately when the faucet is opened. The ability to have access to nearly instantaneous hot water is probably the number one advantage.

Water Usage: Because hot water is delivered nearly immediately, less water is wasted. When installed, the need for waiting for the water flow to reach your desired temperature is eliminated. This is particularly useful in areas where water is in short supply. A huge benefit of using a circulation pump is it’s ability to save a significant amount of water, resulting in a savings of money and time.

Ease of Installation: Installing a circulation pump is relatively easy and you’ll likely already have the tools you need. The majority of pump models are designed for the average home plumbing system. In addition, no special permits are required to add a pump to your water heater.

Ease of Operation: As a general rule, circulating pumps are very straightforward and easy to operate.

Selection: Water heater circulation pumps can be found nearly everywhere with a variety of manufacturers and options to choose between.

Saving Water With Hot Water Recirculating Pumps

While the most obvious benefit of hot water recirculating pumps is that youll have access to virtually instant hot water from every sink in your home, youll also be saving a lot of water. Because there are so many factors that go into calculating the water savings, it is difficult to quantify exactly how much youll conserve, though some estimates place the amount as high as 15,000 gallons per year. However, certain factors can increase or reduce your savings.

For starters, the size of your pipes plays a major role. Pipes with larger diameters can carry a lot more water than their narrower counterparts, so youll see the greatest savings if you have pipes that are on the wider side. The distance between your water heater and faucets is important as well. If your hot water previously had to travel a long way to reach the tap, your savings will be higher than if your faucets were closer to the water heater.

Choosing Your Hot Water Recirculating Pump System

How to Get Hot Water with a Recirculating Pump | Ask This Old House

When choosing your hot water recirculating pump, your first decision should be whether you would prefer a full recirculating system or a comfort control system. Your budget and the configuration of your home will be among the most important factors in this decision. If plumbers can easily gain access to your pipe system and you can afford to pay a bit more, a full recirculating system will give you the greatest benefit, without the drawback of warming up your cold water on the return. To save money, time, and hassle, a comfort system may be the better option for you.

Once you have selected the style of system you would like, your next step is to choose a sensor or timer to control it. If you dont want to have to worry about programming your system, a sensor can do the job for you by monitoring the water temperature in your pipes. To maximize the efficiency of your system, though, youll want to have the greatest possible control over when your system operates. For this, youll need a timer.

Simple, mechanical timers are easy to install and even easier to set. However, you may be limited in how detailed you can get with your timing. If your schedule changes from one day to the next, an electronic timer will give you greater flexibility. You can typically program several scenarios to accommodate changes in your daily schedule, like from workdays to the weekend or if your schedule doesnt follow the typical work week.
