Hot water booster pump refers to a dc centrifugal water pump, that water in the pump chamber rotates at high speed along with the impeller when the pump work, and generates centrifugal force to pressurize the hot water. It is also known as a water pressure booster pump, pipeline booster pump. Its main function is to carry out a second pressurization for the water inside the original pipe. After that the outlet pipeline pressure is the inlet pressure plus the booster pressure, thus reaches the pressure boost affect. It can solve the problem that the pipeline water pressure is not enough. Or make the shower head outlet water pressure reach the pressure that meets user’s needs.
As a 12v water pump, hot water booster pump are mainly used in hot water circulation and boost, home water booster. And used as a water heater pump for air source water heater, solar water heater, electric water heater, instant water heater, gas water heater and so on.

Hot Water Booster Pump: The rotor of the motor drives the impeller to rotate at a high speed when working. And the impeller drives the liquid to rotate at a high speed to form a centrifugal force. So that, the liquid gets high energy and flows out of the impeller. And increase the kinetic energy and pressure energy of the liquid to increase the water pressure.
Hot Water Recirculating Pump: The working principle of the hot water recirculating pump is use the pump to circulate the water. For example, the circulating pump circulates the hot water in the plumbing heating pipe.
From the installation position of the pump: People generally install the water pressure booster pump on the water inlet pipe; While, it should install the small water circulation pump on the return pipe to pressurize the system water pressure to circulate water.
From the scope of application: We generally use water booster pumps in central heating systems. Or use them in water heater that with small pressure which requires supercharging. While people mainly use the circulation pump for self-heating system. Or use them for water circulation in large and medium-sized household heating systems. As well as use them for floor heating and hot water circulation.
From the supercharging pressure: Booster pump mainly solves the problem of small water pressure in system. It belongs to a type of pump with a small pressure. While circulation pump has a more higher pressure than the booster pump. It can make the water circulating in the entire heating system.
From the product operation: Booster pump is mostly automatic control. That is, the switch automatic control the water flow. It will automatically activated, as long as there is water flow . While the switch will automatically turns off when there is no water flow . The circulation pump mostly manually control the switch’s on and off , so as to realize the pump’s working and stopping.
Relatively speaking, the pipeline booster pump has no high requirements on the flow rate and the medium to be transported. Therefore, the choice of the booster pump is mainly considering the appropriate flow and head. The selection of the booster pump should consider from five aspects in accordance with the process flow and requirements on drainage. That is liquid delivery capacity, head, liquid properties, piping layout, and operating conditions.
Flow rate is one of the important performance data of the booster pump selection. Which directly relate to the conveying capacity of the water heating system. For example, the system design engineer can calculate out the normal, minimum and maximum flow rates of the pump . People should select a booster pump on the basis of maximum flow rate, and also take normal flow into consideration. And choose 1.1 times the normal flow rate as the maximum flow rate, when there is no maximum flow rate.
The water pressure requirement for the hot water system is another important performance data for selecting a hot water booster pump. Generally speaking, people should select a pump with a water head that is 5%-10% higher than the required system water head.
The efficiency of hot water booster pump is the most important factor in measure the performance of the pump, instead of the power. In the case of a pump with same head and same flow rate, the the more lower power is the more higher efficiency is. That is to say, the performance is more good. Recommend to purchase a brushless dc pump as a booster pump, because the efficiency of the brushless DC motor is much higher than that of the AC pump. Moreover, its life span is much longer than that of the AC pump and the brushed DC pump.
When install the hot water booster pump. People should install the water booster pump horizontally or vertically according to the “Installation Mode” display. The direction of water flow should be consistent with the direction of the arrow on the pump body. And should install it as close as possible from the water level. Therefore, we should select the pump according to the direction of the water pipe of our home. At the same time, the size of the inlet and outlet pipes of the home booster pump should match the size of our home water pipe. The common household water pipes are 1/2 inch thread head pipe and 3/4 inch thread head pipe.
The main parameters of the hot water pump are power, head and flow, and the pump market is mixed. Many manufacturers often fake parameters in the nameplate in order to cater to consumers’ pursuit of high-parameter psychology. There are many unscrupulous manufacturer often directly claim a normal temperature water pump as a hot water pump. When people buy such a pump and operate it for a long time in a hot water environment. It will not only short the service life of the pump, more seriously will causes a short circuit of the wire to cause a fire. So, people should pay attention to identify this.
Some times it is not always possible to solve the problem by installing a hot water booster pump when the water pressure in hot water systems pipeline is not insufficient. It can solve the problem of insufficient water pressure by installing a booster pump for a old house water tank. However, like the aging of the pipeline block and the excessive 90 degree elbow will also reduce the water volume and result in insufficient water pressure . For insufficient water pressure caused by these reasons, the improvement effect of a booster pump is limited. In addition, if people install a hot water purifier with low water purification capacity. While the water consumption is too large, then the water flow will become small. Therefore, it is also with no effect, if people install a hot water booster pump under this condition.
With the improvement of people living standards, low-frequency noise sources appear in residential buildings repeatedly. Especially the low-frequency noise generated during the operation of a high-rise pumping houses has seriously affect the residents’ health. The low-frequency noise of the hot water booster pump has a strong penetrating ability to the building. It is prone to neurasthenia, insomnia, headache and other adverse symptoms, if people live in the low-frequency noise environment for a long time. Therefore, people should do some to decrease the pump working noise.
The working noise of the booster pump mainly includes: aerodynamic noise generated by the gas/liquid during the transportation process, noise generated by the vibration of the machine mount base, and work noise of the motor.
Dealing with aerodynamic noise is relatively easy in terms of pump noise control. Common methods include adding sound insulation cover and using sound absorbing materials.
Conduct comprehensive damping and sound insulation for the pump pipe. On the one hand, it can reduce the vibration of the pipe. On the other hand, it can also play the role of shielding the air sound.
