How to Find the Best Hot Water Recirculating Pump?


You must be pretty thrilled to get one of the units that we have included in our recommendation list. And even though all of them will offer your decent recirculatory performance, if you want to get the most out of the money that you are going to spend, you have to keep these points in your mind before buying:

Motor

Just like any other pumps, the thing you need to prioritize the most for these is the motor. And the first thing to consider about this would be the power. The higher the power, the faster the water flow will be.

And even though most of these do not indicate the HP of the motor, the indication of the power would be the GPM rate. Usually, the higher-powered units are going to have a high GPM rate.

Aside from power, you would also have to consider the efficiency of the motor. You would not want to raise the electricity bill for your house that much after installing one of these, would you?

For that reason, you should shoot for the units that pack an efficient motor. Those will consume a relatively less amount of power during operation.

Lastly, you need to consider whether the operational noise of the motor is low or not. Having something that makes a lot of noise will not only be inconvenient for yourself but also the neighbors that are around you. Considering that, we would recommend shooting for the ones that have a quiet motor.


Installation Procedure

Another thing that you need to consider when buying these is the installation procedure. You would not be able to carry out the installation by yourself if you get something that utilizes intricate parts.

For those, you would have to rely on a plumber, which means you would have to spend extra money. Keeping that in mind, the ones that have a simple installation method are the ones you should get.

Alongside that, do make sure that the package comes with all the necessary hardware. If you happen to get something that does not ship with the required screws, valves, and mounting hardware, you would have to purchase them separately.

Built-in Timer

If you do not want to go through the hassle of turning the unit on and off manually, you should opt for the ones that have a built-in timer. With those, you will be able to set a designated timer in which the motor will start operating. And once that designated period is over, the unit would automatically turn itself off.

Power Cord

Another thing that you would have to consider is the length of the power cord. The lengthier the cable will be, the easier the installation process would be. You would not have to go through the trouble of getting a cable extender or a power strip if the power outlet is relatively far.

For that reason, you should shoot for units that pack a long power cord.

Build Quality

One of the most critical factors for these is the build quality. And for this factor, the first thing that you need to consider is the material. Most will be of stainless steel or cast iron, or some other type of metal.

No matter which material the one that you are shooting for is utilizing, make sure that it can resist rust and corrosion. Without that capability, you are going to get an extended service out of these.

Aside from the material, make sure that the form factor is compact as most of the plumbing systems do not have that much amount of space. However, if you have a spacious system, then you can stay a bit worry-free in this regard.

Advantages of Having The Hot Water Recirculation Pump?


As you have guessed by now, there are plenty of advantages of having one of these installed. However, if you are still clueless about the factor, these are key advantages that you would be able to enjoy:

Better Circulation

The heating system is usually located closer to the shower or a designated faucet for most of the house layouts. And it takes ages for hot water to get to the other showers or faucets. But with one of these installed, you will be able to enjoy warm water right after turning the knob on.

Low wastage of water

As the name suggests, these recirculate water. That means no water is going to be wasted that is inside the heating system. You are basically going to take an eco-friendly approach in the case of enjoying warm water throughout your entire house.

Money-Saving

Because the warm water is going to reach most of the faucets instantly, you would not have to keep your heater on for a prolonged amount of time. That means you save a big chunk of money from the electricity bills or gas bills, considering your heating is gas-based.

Also, as you are going to use all of the water efficiently, you would be cutting down water bills as well.

Cleaning and Maintenance


If you want the system to last for an extended amount of time without showing any signs of performance degradation, you need to take proper care of it. And the cleaning and the maintenance process is as follows:

  • First of all, you need to unplug the power cable. Then take off the hose and the other connectors that are connected to the system. Store them somewhere near you.
  • After you have disassembled the pipes, you need to disassemble the housing. For that, you would need to work with screws. Unscrew each of the screws and get access to the insides.
    Check whether the bearings have proper lubrication or not. If they are clogged up with dust, you need to clean them properly.
  • Then you need to clean the hoses. Make sure that there are no signs of mildew or mold growth. If you see any of that, you need to clean the inside by running hot water.
  • Once all of the components are cleaned, you would have to reassemble the parts.

Installation of Recirculation Pumps


No matter how powerful of a unit you get, you would not get the maximum performance out of it if you can not install it properly. And the installation procedure that is applicable for most of these units are as follows:

  • First, you will have to turn the water heater off. If you are using a gas-based water heater, you need to ensure that the gas line is turned off as well. After that, you will also have to make sure that all the faucets and showerheads are turned off, or else when you are going to work with the plumbing pipes, there would be a lot of leakages.
  • Then you would need to disassemble the pipes. After that, you must drain all the excess water from the heater and the pipes. If you do not drain the water, you will get a blast of cold water after carrying out the installation process.
  • Now that you have disconnected all of the pipes, you would have to connect the adapters and threadings. Ensure that the threadings are properly installed, or else there would be leakage after you turn the water system back on.
  • Finally, you need to install all the mounting brackets and install the pump in place. Then you have to reinstall all of the pipes and turn the system back on.

Who Need Hot Water Recirculation Pumps?


There is a high chance that you are wondering whether you should invest your money in one of these or not. Well, here are the points that would make you sure whether you should get spend your valuable money on one of these or not:

You Want Instant Hot Water

As we have mentioned earlier, most of the houses would have the heating system installed near a designated spot. And getting warm water that is far from that place would require some waiting. If you want to get instant hot water, then you should get one of these.

You Want Less Wastage of Water

Like we mentioned, these can recirculate the water efficiently from the heating system to the faucets and showerheads. As a result, the amount of wattage would be considerably low.
