Domestic Hot Water Recirculation Pump

A domestic hot water recirculation pump helps direct the hot water back to the water heater within a short given time.  In most cases, the hot water recirculation system is incorporated with a heating system in the household so that it can return the unused hot water back into the heater.

Typically speaking, when we turn off the hot water tap, the hot water does not go anywhere but stays where it is in the pipes. After a while, the hot water cools down. Therefore, the next time we turn on the hot water tap, we need to wait for a minute for the cool water to drain out so that the hot water can come out. The cooled down water goes to waste as a result; it is genuinely a waste of time and a waste of water. With a Domestic Hot Water Recirculation Pump, the unused hot water in the pipe does not just sit there to cool down anymore; it will be directed back to the water heater by the pump. This way, the water does not go to waste and the time to wait for the hot water is saved as well.

 

The Goal of Hot Water Recirculation System

The domestic hot water recirculation pump is a machine that can direct the hot water back to the water heater within a short given time. In most cases, the hot water recirculation system is incorporated with the heaters in the house so that it can return the unused hot water back into the heater. Such a system normally employs a hot water pump to drive the water in the pipelines.

By implementing the hot water recirculation system, not only the unused hot water is not wasted, but the water users do not have to wait for the hot water to come out the next time they turn on the hot water tap. It is estimated that the domestic hot water recirculation pump can roughly save thousands of gallons of water for a household every year.

In general, the purpose of a hot water recirculation system is to make sure that the hot water is always available when the water users turn on the hot water faucet. The ultimate idea of applying such a system is to reach the goal that whenever the hot water faucet is turned on, there is hot water coming out immediately. It minimizes the water waste and the time to wait for the water to heat up. In addition, achieving the goal saves the utility bill of the household too.

The features to look for when searching for a Hot Water Recirculation Pump

The hot water recirculation pumps are convenient aid that saves water, time, and money for people and they are available on the market. The house owners can easily get access to a machine as such. Here are some features and options of the circulation pumps that house owners should pay attention to when choosing the best domestic hot water recirculation pumps for their own house.

The first quality a hot water recirculation system should have is durability and this quality has a lot to do with the materials that make the machine. A good quality hot water recirculation system is usually made of stainless steel which is rigid, corrosion-resistant, and able to withstand heat over a long period of time.

The recirculation pump that is made of stainless steel is expected to last over years or even decades. So, when looking for a recirculation pump, go for the models that are made of high-quality materials.

Next, the timer may be a good accessory for the hot water recirculation pump. With a timer on the system, the water users can set the schedule for the pump to turn on or shut as desired. Schedule the running time of the pump can further save the energy the machine takes.

Some house owners set the pump to run only during the peak usage times such as in the early mornings or at night. On some hot water recirculation systems, the timer is a built-in component; if the time setting is needed, these models are the ones that the house owners are looking for.

The other thing to look for is the design of the hot water recirculation system. Though the basic components of such devices are similar, a circulation pump with a good design can shorten the time to install the machine and the maintenance of the pump is likely to be easier.

It is common that some models on the market are claimed to be maintenance-free and the size of these machines are often compact and the design is simple. With a good model design, the house owners are saved from periodically checking if the pump functions properly or not.

 

Hot Water Recirculation Incorporates Pump Heating System

When applying the hot water recirculation pump, it is substantial to first check the heating system in the house. The reason is that the hot water recirculation system may not fit into certain heating systems.

Usually, it is either a heating system with a hot water tank or a tankless heating system that a household applies. If it is a tankless heating system that you have, the energy to run the hot water recirculation pump with the tankless heater may be an issue since the pumps do not have the required power to work with the tankless heaters.
