What type of joint is often used to connect pipes in hydronic systems?

In hydronic systems, a soldered joint is commonly utilized due to its effectiveness in creating tight, leak-free connections between copper pipes. Soldering involves melting a filler metal (solder) to bond the pipes together, which is particularly advantageous in systems carrying water because it can withstand the pressure and temperature fluctuations typically experienced in hydronic heating systems.

Copper is a prevalent material in these systems due to its excellent thermal conductivity and longevity, and soldering is specifically suited for joining copper pipes. The process ensures that the joint is durable and resistant to leaks, which is crucial in maintaining the efficiency and effectiveness of the hydronic system. Additionally, soldered joints are less complex and can be performed relatively quickly with the right technique, making them a practical choice for plumbing professionals.

In contrast, while options such as screwed, welded, and flanged joints have their own applications in various piping situations, they may not offer the same level of reliability or ease of use specifically for the materials and conditions commonly found in hydronic systems. For example, screwed joints can introduce the potential for leaks due to thread wear, welded joints require more extensive preparation and equipment, and flanged joints, though strong, may require more space and additional gasket materials that can complic
