Is there such a thing as an online calculator where you can plug in your btus load, pipe size and length, and have it give you pump recommendations or at least head and flow?
Thanks!

Are you looking for a commercial application? OR are you looking at residential system (less than 300,000 BTUh)? For the small stuff, a simple rule of thumb is found here: https://documentlibrary.xylemappliedwater.com/wp-content/blogs.dir/22/files/2020/01/FH-Z100B-BG-Zoning-Made-Easy-2.pdf starting on Page 5 and ending with this

But I may have used a slide rule in the past. Now there's an app for that.

The best way is to use the old Bell and Gossett wheel that Gill Carlson invented. You can get one from your local B & G rep. If you want the electronic version, you can use the B & G "system sizer" which you can download for free from B & G (zylem) web site.

Like any calculator the more accurate the #s you put in the more accurate your answer will be.

Once you have the pump head and flow calculated you can call your pump supplier and they will size the pump.

Turn your btu loads into gpm required as @EBEBRATT-Ed suggested.
Then find pipe sizing tables online. The Plastic Pipe Institute has a great one for any plastic pipe material.
