What is a typical method used to filter water in hydronic systems?

Using a strainer is a typical method employed in hydronic systems to filter water. Strainers are designed to remove debris and particulates from the water circulating through the system, which helps maintain the efficiency and longevity of the components, such as pumps and heat exchangers. By preventing the buildup of solids, strainers ensure that the system operates optimally and reduces the risk of clogs that can lead to increased maintenance and downtime.

Strainers generally feature a mesh or perforated element that captures larger particles while allowing clean water to pass through. They are commonly installed in various locations throughout the hydronic system, such as near the pump or at the service entry point, to protect vulnerable components from potential damage.

While other methods, such as using an air separator, filter cartridges, or chemical treatments, can also be employed in hydronic systems for different purposes, they do not serve the specific function of filtering particulates from the water in the same manner as a strainer does. An air separator, for example, is primarily used to remove air bubbles from the water, and chemical treatments are designed to address issues like corrosion and scaling rather than physical filtration. Filter cartridges serve to remove finer particles and contaminants but are not always standard in every hydronic system,
