Circulation pump vs. circulation pump

Currently used solutions in the field of water installations DHW and heating systems effectively prevent heat loss and provide hot water in detached buildings. In each of these cases, a properly selected pump with optimal parameters is needed.

Central heating systems use central heating circulation pumps, which help to achieve the optimum temperature in rooms and maintain it without unnecessary losses. Their main task is to distribute the working medium over the entire heating surface. The circulation pump can be used both for traditional radiators and underfloor heating - its operation depends on the specific type of heating device.

In turn, a circulation pump is a device that ensures the circulation of hot water (including drinking water) in a building to which water is not supplied from municipal waterworks. This refers to both radiators during the heating season and hot tap water. Using a circulation pump is associated with a reduction in the energy consumption needed to heat and cool water in the installation.

The devices available in this category are made of durable cast iron, which guarantees high resistance to mechanical damage. Individual CO pumps with a threaded connection are designed for simple heating and air conditioning installations, as well as for hot water circulation (as circulation pumps).
