Circulation pumps are one of the key elements of water installations. Their task is to effectively pump hot water. Thanks to this, they enable maintaining the appropriate pressure in the entire system. However, for the pump to operate efficiently and without problems, it is necessary to select the appropriate 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 the new entry!

How does a circulation pump work?
A common problem in water installations is that after opening the hot water tap, cold water flows from the tap for some time. This is unfavorable for many reasons. It significantly reduces the comfort of using the installation and extends the time needed, for example, for cleaning. The problem also affects residents' wallets. Cold water is often unsuitable for use (e.g. if we want 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 that hot water remains in the pipes when it is not used by the users of the installation. The longer the periods between each opening of the hot water valves, the more water will be cooled down. Fortunately, these types of problems can be effectively prevented. The best way is to install a circulation pump .
The use of such devices is to periodically induce movement in a closed circuit. In a water installation, this results in the removal of residual heated water from the pipes and replacing it with a newly heated liquid. The cooled water is directed back to the tank where it is heated. For users of the system, it translates into much higher comfort of use - hot water flows from the tap almost immediately after turning on the tap.
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 purchasing it. The most important of them are:
- efficiency – it 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 of the highest receivers.
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 can be sent by the thermostat when a drop in room temperature is detected.
In water supply systems, the circulation pump can be activated at specific times to ensure continuous water flow and avoid stagnation. In such a situation, the device can be connected to a clock or controlled remotely. The method of starting the circulation pump therefore depends on the needs of the system and operating conditions.
What are the differences between a circulating 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 use of both solutions. Circulation pumps are used to pump medium in heating or cooling systems, while circulation pumps are designed for water installations supplying hot water. This translates into a number of other differences, including the material of manufacture, the construction solutions used and technical parameters.
Circulation pumps are irreplaceable in water installations, providing quick access to hot water and eliminating energy losses and uncomfortable waiting for its inflow. When selecting a pump, pay attention to capacity and lift to ensure optimal system performance.
