Circulation pumps are one of the key elements of water installations. Their task is to effectively pump domestic hot water. Thanks to this, they make it possible to maintain the appropriate pressure in the entire system. However, in order for the pump to operate efficiently and without problems, it is necessary to choose the right model. So what should you pay attention to when choosing a circulation pump for domestic hot water? How do these types of devices work? How do they differ from another popular solution - circulation pumps? We explain everything in a new entry!

How does a circulation pump work?
A common problem in water installations is that after turning on the hot water valve, cold water flows from the tap for some time. This is disadvantageous for many reasons. It significantly reduces the comfort of using the installation and extends the time needed, for example, for washing. The problem is also felt by residents' wallets. Cold water is often unfit for use (e.g. if we intend to take a shower), so it remains unused. The energy previously used to heat the water is also wasted.
The reason for this state of affairs is the retention of warm water in the pipes when it is not used by the users of the installation. The longer the periods between individual openings of the warm water valves, the more water will cool down. Fortunately, such problems can be effectively prevented. The best way is to install a circulation pump .
The application of such devices is the periodic induction of movement in a closed circuit. In a water installation, this results in the removal of residual heated water from the pipes and its replacement with newly heated liquid. The cooled water is directed back to the tank, where it is heated. For users of the system, this translates into significantly higher operating comfort - hot water flows from the tap almost immediately after the tap is turned on.
There are various models of circulation pumps available on the market. To be sure that a given device will guarantee efficient and trouble-free operation, you should pay attention to several aspects when buying. The most important of them are:
- efficiency – should be adjusted to the amount of water in the installation and the average number of water changes;
- lifting height – must be adjusted to the height at which the highest receivers are located.
When does the circulation pump turn on?
The circulation pump is started when necessary. 
pumping fluid in a closed circuit. In most systems, the circulation pump is started in response to a signal related to the demand for heat or water in the system. In an underfloor heating system, it may be sent by the thermostat after detecting a drop in room temperature.
In water supply systems, the circulation pump can be started at specific times to ensure continuous water flow and avoid stagnation. In such a situation, the device can be connected to a timer or remotely controlled. The method of starting the circulation pump therefore depends on the needs of the system and operating conditions.
What are the differences between a circulation pump and a circulating pump?
Circulation pumps are often confused with circulation pumps . Although both devices have very similar applications, there are also significant differences between them. The most important issue is the application of both solutions. Circulation pumps are used to pump the medium in heating or cooling systems, while circulation pumps are designed for water installations that supply hot utility water. This translates into a number of other differences, including the material of manufacture, the design solutions used, and technical parameters.
Circulation pumps are irreplaceable in water installations, providing quick access to hot utility water and eliminating energy losses and uncomfortable waiting for it to flow. When choosing a pump, pay attention to efficiency and lifting height to ensure optimal system operation.
