Boilers with circulation pump

Circulation pump

— boilers with built-in circulation pump.

Such a pump ensures the movement of the coolant along the heating circuit, due to which the heat is evenly and efficiently distributed over the radiators. Similar devices are also available as separate devices. However, buying a boiler with a circulation pump eliminates the need to purchase additional equipment and simplifies the heating system. But if a separate pump fails, it is enough to replace only it, and the module built into the boiler may require complex and expensive repairs, and at this time the heating system becomes unavailable.

Also, note that it is theoretically possible to build a heating system without a pump based on natural circulation; however, such systems have several disadvantages, so it is still preferable to use additional equipment.
