The effectiveness of a radiator in dissipating heat depends not only on the temperature difference between the radiator and the surrounding air but also on its surface area. As heat is transferred from the radiator to the environment, the temperature of the hot water gradually decreases based on the size and flow rate of each radiator section.
When radiators are connected in series—where the outlet of one group serves as the inlet for the next—the water temperature progressively drops across each group. Lower water temperatures result in reduced temperature differences with the surrounding air, which in turn lowers heat dissipation efficiency. For this reason, it's advisable to avoid installing more than four groups in series. While series connections save costs, they are most efficient with no more than six groups. To optimize performance, small radiators should be positioned at the front, with larger ones at the back. One-inch ports and 32 mm pipes are recommended for proper functionality.
In contrast, connecting radiators in parallel ensures that all groups receive the same inlet water temperature. This setup creates a significant temperature difference with the surrounding air, enhancing heat dissipation efficiency. However, maintaining adequate hot water flow through each radiator is critical. A downside of parallel connections is that water returns quickly at first but slows down over time. Adjusting valve sizes for each radiator according to their position is essential to achieve balanced heat output. Although easier to install and layout, balancing flows across radiators can be time-consuming.
Under ideal conditions, if the inlet temperature is consistent, parallel connections provide better overall heat dissipation compared to series configurations. Parallel systems also allow individual temperature control for each radiator, minimizing disruptions in case of maintenance issues. This setup uses multiple valves and pipes, ensuring that a problem with one radiator doesn’t affect others.
For optimal performance and convenience, using separate loops for each radiator is the best approach, particularly in residential settings. Though this method incurs higher pipe and labor costs, it offers excellent heat distribution and automatic balancing. However, this design is less practical for large-scale applications like offices or factories due to its complexity and cost.
In conclusion, while series connections offer cost savings, parallel setups provide better heat distribution and flexibility. Investing in quality installation ensures even room temperatures and minimizes future repairs.
