Your building represents a
significant long term investment.
Selection of the proper heating and
ventilation systems for your
specific building is crucial to insure the
comfort and energy efficient performance you
deserve. Unfortunately, to meet budget
constraints, mechanical systems are often
cheapened and corners cut that the building
owner may pay for over and over again.
If you are storing a product that may be
adversely affected by moisture or
condensation, the difference between direct
fired heating equipment and indirect fired
heating equipment could be a factor you need
to seriously consider as you evaluate the the
best choice for your building application.
Although most people have been led to believe
that direct fired heating equipment efficiency
is 92%; the real systematic energy efficiency
can be much, much lower. A research study
project by Mr. Bin Wang at Indiana University
Purdue University Indianapolis (IUPUI)
released in July 2019 sheds new light on the
real efficiency of HTHV heaters.
