Pros and Cons of hot water recirculating pump
There are several reasons as to why you should consider installing a hot water recirculation pump.
Here are some pros and cons of hot water recirculating pump:
Convenient access to hot water
The most obvious reason is that you get instant access to hot water every time you run a bath or switch on your faucet.
Depending on how big your house is and also the length of your plumbing pipes, it may take a few minutes before the hot water reaches various fixtures.
If you do not want to stand around waiting for the hot water, then investing in a recirculating system that will continuously pump the much-needed hot water throughout your house.
Reduce Water Wastage
Many people usually let the water run for a few minutes to allow hot water to reach the tap or shower finally.
The truth is that you could be wasting thousands of gallons per year as you merely wait for that heated water to be delivered.
When installed, hot water recirculating pumps eliminate the need to wait for the flow of water to reach that perfect temperature.
This benefit is especially significant in places where there is a short supply of water.
Easy to Install and Use
Even though installation by a professional is usually recommended, the process of setting up a hot water recirculating pump is moderately simple.
Most of the domestic pump models are designed to be installed with minimal hassle and will suit most plumbing systems.
Also, you do not need to apply for any special permits to connect a hot water recirculating unit to your home.
When it comes to usage, these pumps are quite straightforward and very simple to operate.
Wide Selection of Products
Hot water recirculating units have long been used in many restaurants and hotels as a way of conveniently supplying guests with instant hot water.
Today, you can find a wide range of recirculating pumps designed for domestic use as more homeowners have started taking advantage of all the benefits that these pumps can provide.
However, with so many options, it helps to do a bit of research to ensure that you are choosing the recirculating system that is the perfect fit for your home.
How does a Hot Water Recirculating Pump work?
The average home wastes roughly 15,000 gallons of water every year.
A large part of this wastage comes from letting water flow directly into the drainage while waiting for it to reach the desired hot temperature.
This wastage process is repeated numerously for showers, dishes, baths and many other daily household tasks all over the country.
Here is a brief explanation of how hot water recirculating pumps work and how they can help you prevent this wastage.
Let’s look at basic plumbing, particularly regarding how hot water travels from your heater to the shower or faucet.
Once the water heater has heated up the water, that hot water must then be transported to fixtures around the home.
However, since there is cold water already in the piping, it must be first moved out before hot water can reach the tap.
Installing a hot water recirculating pump helps to solve this issue through short-circuiting your plumbing system temporarily such that the supply of hot water is connected directly to cold water.
The recirculating aspect of the pump comes from the fact that the cold water is redirected back into the water heater rather than being wasted.
Once the pump bypass valve detects that the hot water is instantly coming out from the faucet, the pump stops automatically.
The result of using hot water recirculating pumps is nearly instantaneous hot water whenever you open the tap, with no wastage of water.
It delivers the hot water at last five times faster than using conventional plumbing, which saves time, energy, sewage and water costs.
These pumps can be easily activated by different methods including a timer, switch or water flow sensors.
Classifying Hot Water Recirculating Pumps
There are several essential options when it comes to choosing a recirculating pump, primarily based on how you intend to install and use it.
Here are some of the main alternatives to consider:
Recirculating Pump Installed Near the Water Heater
For this installation method, a hot water recirculating pump is strategically installed near the primary water heater and is best for buildings that already have a dedicated or preinstalled return line.
The hot water supply line will always be filled with hot water while ensuring that no warm or hot water mixes with the cold water.
The disadvantage of using this method is that the supply branches of hot water that run to the individual fixtures around the building will not stay hot.
It means that you should still expect a slight delay as some cold water is being purged before the hot water finally reaches the tap once it is turned on.
This type of hot water recirculating pump installation near the building’s water heater is common in most new properties.
Recirculating Pump Installed at the Usage Point
If you do not have a dedicated return line for hot water, then you can opt toinstall the recirculating pump at the exact usage point.
This kind of pump is used nearer to the water fixture instead of the central water heater.
For example, it can be placed below a sink and can then be used to send cold water back to the heater through the cold supply line until hot water reaches the fixture.
There is a definite benefit of having the pump installed near a faucet, and that is because it provides faster access to hot water, with minimal delay.
This type of hot water recirculation system can be used in any building and is especially helpful where no dedicated return lines are installed.
The other way of classifying hot water recirculating pumps has to do with how they work, e.g., with a timer, thermostat or even on demand units.
Here is a b
Timer and Aquastat Powered Units
A hot water recirculating pump with an aquastat and time design means that the hot water will be maintained at a specific temperature for a particular set duration.
Both the aquastat and the timer work efficiently together to ensure there is sufficient hot water when needed.
The user can set up the timer to ensure that there is hot water every morning, or whichever time they intend to use hot water.
At this time when the pump is active, the thermostat in the pump maintains a consistent flow of hot water within the pipes.
Under this kind of system, the recirculating pump does not run nonstop throughout the day.
It will only start running during the periods set in the timer settings and also for as long as the thermostat senses that the water has a low temperature than is required.
The result is that it delivers hot water very quickly at cert times during the day when you anticipate using it but more efficiently.
Besides getting hot water quickly to all fixtures in your home, this kind of recirculating pump delivers water that is a lot hotter.
The reason for this is that the plumbing system is usually pre-heated due to the recirculating hot water.
As the supply line of hot water will already be heated up, there is less heat loss when the water travels from the heater to your tap or faucet, thus providing much warmer water.
Just as the name suggests, these on-demand hot water recirculating pumps require user activation every time to operate.
Once the user activates the pump, the system quickly delivers hot water straight from the heater while sending cold water away from the supply line and back into the heater.
The activation controls for the pump can be set up at various locations in the building and are not just limited to where the recirculation pump is installed.
The on-demand unit is more versatile and can include remote controls placed at various parts of the house to initiate hot water flow.
You can even use motion detectors as part of the remote-control system whereby the pump is automatically switched on whenever you walk into your bathroom.
The benefit of using this kind of hot water recirculating system is that it is very energy efficient and offers minimal heat loss since hot water is only provided on demand.
