<br>
If the systems serve distinctly different uses that comprise more than 20,000
sf you are fine. Otherwise, I would use the predominant heat source. It will be
interesting to hear others opinions.<br>

I have an "intermediate" sized building (25,000 to 150,000 sqft) with
several systems in it. can each system be determined separately or should
each by a System type 5/6 depending on Heating source? I would like to
label some small systems as a type 3/4 and some as type 5/6 depending on the
area that is served by the system. <br>

thanks for any opinions that people would like to share.<br clear=all>
