I've started down the road of putting together a drainback system for my house in sunny San Francisco. If you're curious what I'm up to, I'm documenting the process here: http://sfsolarhotwater.blogspot.com/
I'm at the point that I'd like to create some system schematics. I *love* the design of the schematics published in Homepower magazine, but I've struck out trying to find the tool HP uses or anything like it. What are you all using? I need to get this ugly, `key free' SRCC OG-300 diagram:
Into something with a proper `Key' and better legibility. Is there a Visio or OmniGraffle set of templates/stencils that are used in the industry?
Thanks in advance!
Didn't get much in the way of feedback, but figured out how to use Dia to do what I wanted to do. Here's a little write up on using Dia with the solar thermal template: http://sfsolarhotwater.blogspot.com/...irst-pass.html
