Type 1: With Dedicated Heat Exchanger 
 
 
| DEFENDER SAFETY SYSTEM® COMBI2™ AND NON-DEFENDER MODELS The Combi2™ is the ultimate system for perfect home comfort and potable water from a single energy-saving source. The secret lies in the patented 1½" O.D. glass coated (Vitraglas®)steel coil heat exchanger. First, the Combi2™ heats the potable water in the tank. Then, the heat from the hot water is efficiently transferred through the heat exchanger to the heating fluid within the coil. 75-gallon model does not include the Defender Safety System®.   |
