Excess stack draft can be robbing your system of heating efficiency
no matter how well the equipment is rated. Boilers are
rated by most manufacturers in a lab environment with a 3' stack
venting into a hood! In actual practice, rarely do boilers
perform up to these specs. The Stack Draft Regulator changes
all this by thermo-dynamically controlling stack draft, and
eliminating excess stack draft. This is done with no moving
parts, and no controllers to fail! Once the boiler is tuned,
it stays tuned, even during windy days. This can readily be shown
and proven using a typical flu gas analyzer.

ECMI, our Associates, and installers proudly use Bacharach Instruments
when conducting feasibility studies, site surveys, and SES
installations for our clients.
Note that the ECMI Stack Draft Regulator is
implemented in conjunction with traditional barometric draft regulators
and draft hoods, and
will significantly improve the performance of the stack system.
