Plumbing systems are crucial for proper waste management and water handling in homes, industries, and commercial buildings. John Siegenthaler, an engineer and recipient of the ASHRAE Lifetime Achievement Award, introduced extended manifold systems for managing hot and cold water distribution efficiently. In this article, we’ll explore John Siegenthaler’s extended manifold system, its unique benefits.
What is John Siegenthaler’s Extended Manifold System?
John Siegenthaler’s extended manifold system is a revolutionary approach to hot and cold water distribution. Typically, plumbing systems have a centralized manifold that branches out to different areas of the building. However, this approach has its issues, including loss of pressure, longer wait times for hot water, and increased energy bills.
To counter these issues, John Siegenthaler introduced an extended manifold system that has multiple mini-manifolds strategically placed throughout the building. This system delivers hot water faster, eliminates wait times, and minimizes energy consumption.

Benefits of John Siegenthaler’s Extended Manifold System
1. Faster delivery of hot water
As mentioned earlier, extended manifold systems deliver hot water faster than traditional centralized systems. The primary reason for this is that the system has mini-manifolds close to the end-use devices, reducing the distance hot water has to travel.
2. Reduced energy consumption
Extended manifold systems use less energy than centralized systems. In traditional systems, hot water has to travel through pipes that cool down, leading to energy losses. Extended manifold systems eliminate these losses by providing hot water only where it’s needed.
3. Increased flexibility
Extended manifold systems have increased flexibility, allowing for customization and scalability. You can add or remove mini-manifolds based on the changing needs of the building.
4. Reduced water waste

Traditional centralized systems tend to have long runs of pipe with water sitting stagnant. Extended manifold systems minimize water waste by providing hot water immediately, reducing the need for running water to reach the desired temperature.
In conclusion, advancements in technology and new approaches to plumbing systems, such as John Siegenthaler’s extended manifold system, are transforming the plumbing industry in 2022. Plumbing experts are looking for ways to decrease energy consumption, reduce water waste, and improve customer experience. And homeowners and businesses are adopting eco-friendly and energy-efficient plumbing systems and appliances. Whether it’s green plumbing, water filtration, smart plumbing, or efficient plumbing, the plumbing industry is changing to meet the demands of the future.
