How It Works - Rinnai EX08c Brochure & Specs

hOw it wORKS

temperature-Sensing thermistor
• Consistently monitors room temperature 2" off the floor
• Accurately detects temperature changes less than one degree
Rinnai Response
• Within 10 seconds, the Rinnai wall furnace begins to gently heat the room at low fan speed
• It increases fan speed and BTU output if necessary to achieve the desired temperature
• Once the desired temperature is achieved, the furnace goes into standby mode
Room Monitoring
• As the temperature of the room gradually drops, the wall furnace restarts and gradually warms
the room back to the desired temperature
• If there is a sudden injection of cold air, the furnace automatically adjusts fan speed and BTUs to
quickly restore the set temperature

the traditional Approach
• Higher operating costs
• Large fluctuations in room temperature
• Slow response to thermostatically controlled heat settings
• Poor distribution of the heat provided through leaky ducts
the Rinnai Approach
• Energy-efficient and economical zone or whole-house heating
• Wall furnace quickly adapts to small temperature changes
• Modulating blower and gas valve automatically adjust to individual heating needs,
providing comfortable, consistent temperature from ceiling to floor
• No ductwork required
ICC-ES® PMG Listings certify that plumbing, mechanical and fuel gas products meet
requirements in codes and standards.
