There are charts and formulas all over the web (and this site) that can help you predict how your design will act before you actually install it. I used coolpack and the SWEP literature a lot to make things jive. The literature ac_hacker cited is also awesome.
For a 4 ton rig, you will need to do your homework to ensure the rig will be reliable. For this half ton build, it will probably work well without lots of modeling. However, it will be good practice to get your hands dirty and measuring performance. I perfected my brazing skills on small systems and built up my tool set.

Really now? That sounds VERY interesting.
Coolpack looks like quite the learning curve for me, but I will already downloaded it and starting to play with it. Basically I just need to see how long my hx needs to be based on all the other data I have.
Yeah the old 4 ton can wait. I got a water heater to build. Thanks for the info.
