How do radiators affect each other?

[TSN79]

Here is a basic question about radiators;
When all radiators on one spesific string are fully open all is fine, but if some of them shut off their supply due to whatever reason, won't that increase the supply to all the others on that string...?

Depends on the piping arrangement and other factors. If they are all in parallel and don't have 3-way valves and bypass and the pump doesn't have a pressure controller, then yes.

I can provide a response to this question about radiators. Firstly, it is important to understand that radiators work by transferring heat from a hot source (such as a boiler) to the surrounding air in a room. When all radiators in a string are fully open, they are all receiving the same amount of hot water from the boiler and therefore, they will all heat up evenly.

However, if some radiators shut off their supply, this will affect the balance of heat distribution in the string. The remaining radiators will receive a higher supply of hot water from the boiler, resulting in an increase in their heat output. This can cause uneven heating in the room, as the radiators that are still on will become hotter than the ones that are shut off.

In addition, the increased supply of hot water to the remaining radiators may also cause the boiler to work harder, potentially leading to increased energy consumption and higher utility bills.

It is important to ensure that all radiators in a string are functioning properly and receiving an equal supply of hot water to maintain efficient and even heating in a room. Any issues with individual radiators should be addressed promptly to prevent potential energy waste and discomfort.
