Having a hot water recirculating pump installed in your home is usually unnecessary, but it can be quite the luxury if you don’t like having to wait for your hot water to start coming out of the faucet.
A recirculating pumps main job is to make sure that the hot water lines in a building are always getting a fresh stream of hot water pushed into it. When you don’t have a recirculating pump installed you may find that when you turn on the hot water you don’t actually get hot water for a few seconds or maybe even minutes. This is because the hot water that was in that pipe has left the water heater and has now cooled down towards room temperature.

Types of Hot Water Recirculating Pumps
To help you decide on the best type of hot water recirculating pump to use, check out how each type differs from one another.
Traditional Hot Water Recirculating Pumps
The traditional hot water recirculating pump system has its own return line. This connects the hot water pipes to the bathrooms and faucets, and then back to the water heater. The recirculating pump pulls the water from the fixture and into the water heater in order to create a loop. The pump’s hot water loop keeps the hot water accessible in the tap whenever you need it since it is kept warm in the hot water pipe.
There are also some traditional hot water recirculating pumps that include a built-in timer. This way, you can customize the working hours of the pump to save energy costs.
Instant Hot Water Recirculating Pumps
Unlike the traditional hot water recirculating pump, the instant hot water recirculating pump does not need a dedicated line to make a loop. This makes this pump system more ideal for some households and buildings since it is easier to install. In fact, this type of hot water recirculating pump can be installed on any kind of house. It can come from an over the water heater, or from under the sink.
Over the water heater
The pump is installed above the water heater while the check valve is installed far from the hot water heater under the sink. This setup creates the needed pressure to push the hot water into the water pipes.
Under the sink
The pump is installed far from the water heater under the sink. It pushes the hot water to the cold line to be accessible in all water fixtures.
On-Demand Hot Water Recirculating Pumps
Quite similar to the instant hot water recirculating pump, the on-demand pump is activated by its user. Once activated, it pushes the cold water to the hot water pipes then back to the cold water pipe and into the water heater. This creates a temporary loop to heat the water and become accessible in the entire house. This can be really cost-efficient though you still have to wait for the water to heat up.
How to Choose the Best Hot Water Recirculating Pump
Whenever you proceed to buy something best in the market, chances are that you might either get spoilt for choice or might be left perplexed in identifying the right option. Such might be the case for choosing the best recirculating pump for hot water, which is a reason why you need to know the key considerations. A little bit of research, a little bit of knowledge and some comparative reviews will certainly give you an idea of the best product in the market. But before you delve deep into those, here are a few things you must look out into the best rated hot water recirculating pumps.
Check the sturdiness of the material
While choosing the recirculating pump, it is very important to consider how sturdy its material is. This largely depends on the construction as to how it has been made by the manufacturers. For instance, circulators made of bronze and stainless steel are majorly used for recirculation applications in residences. In other words, if the material is lead-free, it will last longer.
Check the connection system
You must always remember that the residential circulators are usually fixed to supply piping. This is done with the support of flanges having sizes from ¾ to 1-0.5 inch. Also, materials of the flange must match up to those used for the pump. By using threaded connections, circulators can also be connected.
Check the pump size and flow rate
For any hot water recirculation pump, one should calculate its flow rate required to overcome the loss of pressure. Besides, you must check the balancing valves, mixing valves, check valves, heat exchangers and other fittings while measuring the size of a recirculation pump.
Check the Horsepower
It is also quite vital to consider the motor strength of a recirculation pump. This motor strength is the horsepower of a circulator pump that affects not only the flow rate directly but also its head loss performance.
Check Temperature Settings
Be wise in choosing such a recirculation pump that would let you choose the exact temperature in regard to the hot water coming out. This would keep you assured of the fact that you are getting water as per the temperature you desired.
Check whether it is User-friendly
No matter how technologically updated is the pump, it must be extremely user-friendly. After knowing all its functions, you must be able to operate it without any hassle. The easier you are able to operate, the more convenient it will be. You must also know when it has gone out of power and when you should switch it off.
Check its required maintenance
There are some inferior hot water recirculation pumps that require a lot of maintenance. In short, if you don’t maintain them well, they might not last long. So, you can always talk to some professional and get to know which models require less maintenance but are high on performance.
