Suburban Gas Heating and Electric Cooling
will save money in the long run.
The Suburban Dynaline
™
3 is a Packaged Terminal Air Conditioner
(PTAC) that combines economical gas heating and high-efficiency
electric cooling in one compact unit for zone temperature room-by-
room control. By comparing the operating costs of Dynaline 3 to
heat pumps or electric resistance heat, a savings of hundreds of dol-
lars per room every year can be achieved.

™
3 Difference
* Bin Hours are the number of hours of operation per year at the mid-point temperature specific to a geographical
location. The BIN hours are derived from historical weather data.
For example , at a location with 7,023 heating BIN hours,
such as Syracuse, NY, with a 2º design temperature, the cost to
heat with Dynaline 3 can save 80% in utility costs compared to
electric resistance. When compared to heat pumps, Dynaline 3
can save 66% . For a building with 60 PTACs, Dynaline 3 can
save over $77,000 in utility costs in one year!
