What is the effect of improper sizing of piping in a hydronic system?

Improper sizing of piping in a hydronic system significantly affects the system's overall efficiency and longevity. When the piping is either too small or too large, it creates flow issues that can lead to inefficiencies in heat transfer and circulation of the fluid.

If the pipes are too small, the fluid will experience increased resistance, leading to higher pressure drops and potentially causing the pump to work harder. This increased workload can result in excessive wear and tear on the components, notably the pumps and valves, which may eventually lead to premature failure. On the other hand, oversized piping may cause inadequate fluid velocity, resulting in sedimentation and issues such as corrosion over time.

Ultimately, maintaining the correct size ensures optimal flow rates and heat transfer, preserving the system's efficiency and reducing operational costs.
