Why doesn’t the temperature on my heater match the temperature display on my wall, or external 
thermostat? 

This is completely normal

. The temperature display on your heater may vary from the 

temperature display on another thermostat (like the one mounted to your wall or a purchased 
external thermostat). The temperature sensor on your heater reads the temperature in, and 
around, the heater. The unit is near the cold floor (and heat rises), which in turn, will display a 
cooler temperature than elevated or external thermostats. 

The best way

 to operate your heater is 

just to set the unit on “High” and dial up to a temperature that feels comfortable to you. Then, leave 
it at that temperature, regardless of the mismatch. The heater will cycle off when the set 
temperature is met or exceeded slightly.   

 

My home is not insulated very well, will this heater help me? Can I use the heater if I have vaulted or 
cathedral ceilings? I live in a structure that is more than 1500 square feet. Will this heater help me?

 

Can I 

use the heater to heat multiple rooms at the same time? Will I be able to use the heater in a basement or 
garage? 

The answer to these is the same. Yes. You will be able to use it, but keep in mind that 
rooms/structures with open floor plans, minimal insulation, adjacent rooms, or high ceilings will not 
retain the heat as efficiently, and may not feel pronounced heat changes. Also, the heater will stay 
on longer (delays the “off” cycle), and may increase your electric costs. Note that if you do use it in 
a garage or basement, the moisture levels must be very low and they must have dedicated circuits 
(15 amps minimum) with no GFCI outlets. If unsure what a GFCI outlet is, contact a certified 
electrician. 

 

Can I use more than one heater at a time? Can I use the heater and another appliance at the same time? 

Yes. But make sure they are not plugged into the same circuit. Each heater (heaters are 
considered appliances) requires its own minimum15 amp circuit 

(with no other items plugged 

into that circuit

). If unsure your circuit meets these requirements, verify with a certified electrician

Risk of fire, damage to property, or injury may result if requirements are not met.  

 

Why does my heater’s fan continue to run even after the set temperature is reached or the power is turned 
off? 

This is normal

. The heater’s fan will continue to run, even after the heater automatically cycles 

down. The fan continues to run so that every last bit of heat is blown out of the heat chamber, while 
allowing the unit to continue filtering your air. Once the internal box/components cool completely, 
the fan should then shut off on its own. In this case, allow a few minutes after the heat cycles off 
(with power on). The fan will shut off faster when the power is turned off.    
  

Why doesn’t the fan speed increase when I change the setting from LO to HI? 

This is normal

. The heater’s fan’s speed is not affected by the HI/LO settings. The fan is designed 

to vent the heat at one soft, comfortable, and energy efficient speed.  What is affected by the HI 
setting is the heat output. In essence, i

n the HI mode, the heater produces “more” heat, rather than 

“faster” heat.
