Want one or more schematics?

If you wish to exchange a donation for a single schematic from the Design Solution Pages simply make an $7 donation and let us know which schematic you want and we'll email it to you in a .pdf format.

We can also make them available in a .dwg or .dxf format for $15 each.

If you wish to have more than one schematic, we accept donations based on fair market value for professional drafting time. Average time for each drawing is a nominal 2 to 4 hours. Let us know what you think is fair.

We also have a great offer for those that wish to have the entire mechanical schematic library...$500 gets your logo and a link back to your website for a whole year plus we'll send you the master AutoCad .dwg page containing all the schematics.

...and if you really want to help out...$1000 gets you the page sponsorship, all the mechanical schematic plus we'll include a 36" x48" poster size version of the The Architectural Guide to Radiant Based HVAC Systems all in AutoCad's .dwg format.
