Bypass in the heating system (definition)

Bypass in the heating system - this is an additional pipeline installed parallel to the main one heating system circuit, designed to bypass part of the system and maintain circulation of the coolant.

Bypass in the heating system: main aspects

1. Principle of operation:
   • Circulation: Bypass provides the ability to bypass a certain section of the heating system, which allows maintaining the circulation of the coolant even when the main circuit is closed or adjusted.
   • Regulation: Usually, adjustable elements such as valves are installed on the bypass, which allow you to control the flow of the coolant and its distribution.
2. Design:
   • Pipeline: A bypass is a pipe that connects two sections of a heating system, allowing the coolant to bypass part of the system.
   • Valves and fittings: Depending on the system design, various valves (e.g. shut-off, regulating) may be installed on the bypass to control the flow.
3. Application:
   • Maintenance and repair: Bypass allows maintenance or repair of a section of the heating system without stopping the operation of the entire circuit. This is especially important for maintaining continuous operation of the system in large or comfort-critical buildings.
   • Distribution of coolant: Used to optimize the distribution of coolant between different sections of the system, for example, between radiators and underfloor heating circuits.
4. Advantages:
   • Continuous operation: Ensures continuous circulation of the coolant in the system, even if one of the sections of the system requires shutdown.
   • Flexibility: Bypass in the heating system allows you to easily change the system settings or add new elements without significant interruptions in operation.
5. Flaws:
   • Additional costs: Installing a bypass requires additional materials and labor, which can increase the cost of installing the heating system.
   • Additional adjustments may be required.: To use the bypass effectively, fine adjustment of the control elements may be required.
6. Bypass types:
   • Hydraulic bypass: Used to control hydraulic pressure and flow distribution in the system.
   • Thermostatic bypass: Regulates the temperature of the coolant depending on the needs of the system.

Installation example:

• In systems with radiators: A bypass can be installed between the supply and return pipes of the radiators, allowing the coolant to circulate even if the radiator is closed for maintenance.
• In systems with pumps: A bypass can be installed to bypass the pump, ensuring that the coolant circulation is maintained if the pump fails or requires repair.

A bypass in a heating system is an important element that ensures flexibility and reliability of the system, allowing for effective control of the flow and temperature of the coolant.
