Bypass valve
A bypass valve is an isolating or throttling valve that is used to bypass another component. The
bypass valve is installed in a pipe that bypasses the other component. Installation of this valve
pursues different objectives:
• Securing a minimum flow
• Protection from excess pressure
• Maintenance without having to deactivate the complete hydronic system
One pipe heating system
In a one pipe heating system, hot water passes through one radiator after the other.
Two pipe heating system
In a two pipe heating system, hot water passes through the radiators via separate supply and
return pipes.
Remote control
Thermostats with remote control are particularly suitable if the control device is difficult to access.
Heating circuit
A heating circuit refers to the hot water cycle in a heating system. (Here, it refers to a surface
temperature balance)
