epanet-js
No installs. No forced cloud storage. Just fast, local-first water modeling — powered by the engine you already trust.
You shouldn't have to choose between speed, security, and affordability just to understand your water networks.


: Stoecker emphasizes the importance of integrating various components—such as HVAC, refrigeration, and process cooling—to achieve overall system efficiency rather than just component performance .
A step-by-step example of the applied to a thermal loop.
The first edition of Design of Thermal Systems was published in the early 1970s and quickly became a staple in engineering curricula. However, it was the , published in 1989 by McGraw-Hill , that solidified its legendary status. This edition was thoroughly updated to reflect the growing impact of micro-computers on engineering practices , marking a significant shift from purely manual calculations to computational modeling and simulation. w f stoecker design of thermal systems 3 edition pdf pdf top
When you secure the , you gain access to a structured learning path. The book is organized into three logical parts:
The book is famous for its practical, equipment-oriented approach to complex topics: : Stoecker emphasizes the importance of integrating various
Techniques such as net present value (NPV) and capitalized cost to compare alternative designs. 3. Optimization Techniques
Refineries use massive networks of heat exchangers to recycle waste heat. The optimization techniques in the book allow process engineers to maximize heat recovery, directly reducing fuel consumption. 📊 Sample Engineering Problem: System Matching However, it was the , published in 1989

The design of thermal systems is a complex and challenging task that requires a thorough understanding of thermodynamics, heat transfer, and fluid mechanics. W.F. Stoecker's "Design of Thermal Systems" is a valuable resource for students and practicing engineers, providing a comprehensive approach to designing thermal systems. The third edition of the book provides updated design procedures, expanded coverage of heat exchangers, and increased emphasis on energy efficiency. By using this book, readers can gain a deeper understanding of thermal system design and develop practical skills in designing efficient and effective thermal systems.

EPANET was a gift to the industry — free, open-source water modeling for all. But commercial vendors built on it, locked away improvements, and left the community behind.
epanet-js is our answer: a faster, simpler, affordable water modeling tool that protects your privacy and sustains the open-source future of water modeling.
We're proud to be part of the next chapter — and we're just getting started.

When you purchase more features in epanet-js, you're investing in the future of open-source EPANET development.
Our open-source model balances innovation and accessibility:
Anyone can build on our code. The two-year commercial-use delay gives us the incentive to keep pushing forward — and that fuels progress for everyone.
That means when you support us, you support more affordable hydraulic modeling software for the entire community.

You may not know this, but for decades, the U.S. EPA has given the water industry an extraordinary gift: the free and open-source hydraulic modeling software EPANET. Odds are, if you've used any commercial hydraulic modeling software today, it was built on the EPANET engine.
The problem is, instead of giving back to their open-source roots like other industries do, big-name software vendors took EPANET's open code, built private tools on top of the engine, and then locked those improvements behind patents and proprietary licenses.
Some vendors even pressured the EPA to focus only on the engine — discouraging any effort to improve the interface or user experience for everyone else.
Those vendors now charge you exorbitant prices to use their software while EPANET lags behind — and utilities, engineers, and educators with smaller budgets suffer.
We think this is backwards — and we're on a mission to change it. We're focused on creating a better experience for the entire hydraulic modeling community.
That's why we built epanet-js under an FSL license — because we want to give you an affordable, easy-to-use water modeling option that creates a sustainable future for open-source EPANET development.
Support EPANET by using software that supports it back.
Simple, quick, and useful right out of the gate — designed to open-and-go.
