Effinity (model PTC) condensing unit heater line is the most efficient gas-fired, condensing unit heater in North America. This industry leading efficiency is a result of coupling Modines Conservicore secondly heat exchanger technology with Modines robust tubular primary heat exchanger design. The Conservicore technology features a secondary recuperative heat exchanger fabricated from AL29-4C stainless steel. This material is superior to other lower grades of stainless steel and aluminum resulting in outstanding ability to withstand the corrosive environment of condensing gas fired equipment.
The separated combustion units draw combustion air from outside to ensure that the unit will always have plenty of fresh, clean air for combustion while increasing the overall heating efficiency. Venting material to be used is PVC, an extremely cost effective vent system.
