At 90% AFUE, the UltraSaver90Plus is the most efficient wall furnace available.  This clean, modern cabinet fits any décor. Choose models in 35,000 or 17,500 BTUs.

Simple Operation – For all of its technology, the US90 is surprisingly easy to operate.  The built-in control panel lets you operate the wall furnace manually or set the built-in thermostat to maintain the desired

Versatile Installation – Thanks to its super efficiency, the US90 uses widely available 2-inch PVC pipe or Empire approved Poly pipe for venting.  Using PVC requires just a fraction of the material cost and labor involved in steel vent pipe.  PVC pipe fits easily inside a standard stud wall, eliminating the additional framing and clearances required for metal vent pipe. The 2-inch PVC pipe can run up to 50 feet to terminate vertically or horizontally.


 Inside the UltraSaver90Plus

  1. Power-vent blower draws in an ideal charge of air (White Arrow) to support combustion.
  2. In-shot burners (Orange Arrows) generate the heat.  (Two burners in the PV35 and one in the PV18).  The two-stage heat exchanger consists of a large-diameter tube and multiple small-diameter stainless steel finned tubes.  Each transfers progressively more heat.
  3. Cooled exhaust (Green Arrows) exits the heater via PVC (or Empire approved Poly vent pipe) at 110 to 120 degrees F.
  4. Room air (Blue Arrows) is drawn into the top of the heater by the blower and forced across the heat exchanger.
  5. Warm air (Red Arrows) exits through the bottom louvers at the front of the heater.
