Hi y'All,
Jeff's coinop article is very interesting. Worth noting that the 
laundromat in Vermont used Propane not Natural Gas, so the savings are 
much more significant. The preheat tank and circulation schemes look 
like a good design. I hope there are some internal baffles in the heat 
exchangers to insure contact with the preheat coil. It is worth running 
calculations on natural gas to see what investment is reasonable given 
the improvement in efficiency reported in the article. This scheme looks 
like a good candidate for adding Apricus solar thermal collectors to the 
setup. I would just set the Solar loop up on a stainless flat plate heat 
exchanger isolation loop and control with a differential controller.
