Hydraulic bypass (definition)

Hydraulic bypass — is a component of the heating system that allows the flow of coolant to be directed along a bypass path, bypassing certain sections of the system, such as radiators or pumps. Bypass creates an alternative route for the coolant, ensuring stable operation of the system in various modes and under various loads.

Hydraulic bypass: main functions

1. Even heat distribution: Provides uniform heat distribution throughout the system, preventing overload or insufficient heating of individual circuits.
2. Reducing the load on pumps: Reduces resistance in the system, which reduces the load on circulation pumps and extends their service life.
3. Support for minimal circulation: In cases where part of the system is blocked (for example, by thermostatic valves on radiators), the bypass ensures minimal circulation of the coolant, which prevents overheating of the boiler and other problems.
4. Automatic operation: In some cases, the bypass may be equipped with automatic or adjustable valves that open or close depending on the pressure and temperature in the system.

Hydraulic bypass is an important element for maintaining stable operation of the heating system, especially in complex and multi-circuit installations.
