What happens if you put a more powerful pump in the boiler?

If you install a more powerful pump in a boiler system, it can increase the flow rate of water or steam, potentially improving heating efficiency. However, this can also lead to excessive pressure, which may risk damaging pipes, valves, or other components. Additionally, a pump that is too powerful might disrupt the system's designed hydronic balance, causing uneven heating or increased wear on equipment. Proper sizing and compatibility with the system's design are crucial to avoid these issues.
