Care & Usage

The heater might start turning on and off frequently. This is called cycling. Cycling occurs when the temperature in the area around the heater is extremely close to the temperature that the heater is set to maintain; as such, slight temperature changes can cause the unit to cycle on and off. Slightly raising or lowering the thermostat can usually reduce this effect. Note: The heater will cycle more often in a High heat setting then in a Low heat setting because the air heats up more quickly.
Heaters contain hot and arching or sparking parts inside which is normal but we would suggest that you check with the supplier of the oxygen equipment as to whether or not it can be used near the heater.

The fan speed should not change when you change the heat setting, the amount of heat being produced will change but the fan speed will remain the same.

NOTE: Fan speeds are held constant to ensure that the fan does not offset heat output.

  • UNPLUG THE UNIT and make sure the heater is placed in an upright position.
  • If the unit has a thermostat, it may be set too low. Turn the thermostat to its highest setting until the heater restarts. Make sure the Selector is in the High, Low, or Eco-Smart(TM) setting.
  • Make sure the electrical outlet or circuit breaker is working.
  • Check for obstructions. If you find an obstruction turn the heater OFF, and UNPLUG THE UNIT. Carefully remove the obstruction and follow the reset instructions.
  • DO NOT attempt to open or repair the heater.
  • If your heater is still not operating, please refer back to the troubleshooting section of your user manual.

Here are some common reasons why a heater may blow cool air:

  1. Some heaters have a fan only setting which will enable the user to use the heater as a fan. If your model has that feature, check to see if the heater is on the fan only setting.
  2. If the heater is on one of the heat settings, rather than the fan only setting, then it may have overheated and shut off power to the heater. Follow the reset instructions found on the heater or in the owners manual.
  3. With some digital thermostats, the fan will run for 30 seconds without heat once the set temperature is reached. This is to blow out excess heat and ensure an accurate and consistent temperature reading.
  4. If the heater continues to blow cool air after checking the above suggestions, please contact our Customer Service team.
Most heaters should not be placed directly against walls because the air intake will be blocked, although some heaters are designed with the air intake in the front so they can be placed against the wall. Check the owner's manual for details regarding the correct placement of your specific model.

Always unplug the heater before cleaning and allow the heater to cool down.

  1. Clean the unit with a soft cloth moistened with a mild soap solution.
  2. NEVER use abrasive or flammable solvents to clean the unit.
  3. After cleaning, be sure to completely dry the unit with a cloth or towel.
  4. Store Heater in a cool, dry location.
  5. It is recommended that you store the unit in its original carton.

TIP: Over time, dust may accumulate on the front grill. This can be removed by wiping the unit with a damp cloth.

It takes several minutes for the heater to provide an accurate reading, so allow the heater a few minutes to adjust the temperature display. Also keep in mind that portable electric heaters measure heat directly near the heater – the temperature may vary from the reading on your wall thermostat.
Most heaters should not be used in bathrooms or in wet areas. Only heaters that are UL rated for bathroom use should be used in bathrooms.

Here are some common reasons that portable electric heaters shut off:

  1. The thermostat on the heater is not set high enough.
  2. The heater needs to be reset due to an overheat situation. Consult your owners manual for additional details.
  3. If the unit has tip-over safety protection: To reset, simply place the heater in an upright position on a level surface.

General Information

Heaters are used for energy savings and comfort. A portable electric heater can supplement a central heating system and actually lower energy bills. By using the space heater to heat just the room that is occupied, the central heating thermostat can be lowered.
You would need to call your local electric company as rates vary across the country. Note that the amount of electricity used by the heater depends on the heat setting selected (wattage) and how often it is running. If a thermostat is used, the heater will only run when the temperature falls below the set temperature.
It is the temperature at which the unit will automatically shut-off. The temperature range is between 149 to 265º F depending upon the model.
Portable electric heaters are intended for supplemental heating. They are not intended to replace central heating systems.
Bionaire® heaters have various safety features and are approved by Underwriter Laboratories (UL) in the United States and CSA or CUL in Canada. As stated in the owner’s manual, certain safety procedures need to be followed when using heaters to reduce the risk of fire, electric shock, and injury to persons.

Auto shut-off helps prevent damage and risks if the heater were to overheat. As soon as the internal temperature of the heater becomes too hot, the unit will shut itself off. If the heater shuts itself off in an overheat situation, you will be required to reset the heater by following these steps:

  1. Turn the heater to the OFF position.
  2. Unplug the heater and wait 10 minutes for the unit to cool down. After 10 minutes has elapsed, plug the heater in again and operate normally.
Heaters are used to produce heat and some models can be hot to the touch. Care should be taken when using a heater. This includes using extreme caution when a heater is used by or near children or invalids, or whenever it is left operating and unattended.
Depending on your unit, your heater may have Auto Shut-off, an Overheat Back-up fuse, Tip-Over protection, and Polarized, three-prong, or ALCI plugs to help reduce the risk of electrical shock. All of our heaters have safety devices and comply with UL safety guidelines in the US, CUL in Canada and GS/CE in Europe.
Heaters are rated by the amount of heat that they produce which is measured in BTU's or British Thermal Units. The average peak output of an electric heater for 1500 watts is 5120 BTUs per hour.


A thermostat is a control that is used to maintain a temperature range in the general area where the heater is located. Most analogue thermostats have an estimated range of 37º to 140º F. By adjusting the temperature knob you can set the heater to turn on and turn off automatically as required to maintain the set temperature range.

  1. Turn the Thermostat Control clockwise to the highest position to start heater. Allow heater to operate and warm up the room.
  2. When the desired temperature/comfort level is reached, lower the temperature setting by turning the Thermostat Control counter-clockwise until the heater stops operating.
  3. This will now be the unit's pre-set temperature level and the thermostat will now automatically maintain that temperature range by turning the heater ON and/or OFF accordingly.

To preset a specific comfort level between 65F and 85F, adjust the thermostats temperature setting to your desired temperature reading. The Display will show the selected temperature reading. When the preset temperature is reached, the heater will shut off. When the room temperature drops below the preset temperature, the heater will automatically turn on again to maintain the preset temperature level.

Types of Heaters

These types of heaters use various heating elements to heat the air. As the air is heated, it rises and is replaced by cooler air from below the element, which then heats up, and the cycle continues. These heaters are quiet because they don’t use a fan to push the hot air into the room and generate even, consistent heat. With large heating surfaces, these heaters are used for whole room heat.
Ceramic heaters are small, powerful and portable heaters. They are energy efficient and safe while providing instant warmth. They are perfect to add extra warmth to small offices or to heat cooler back rooms. Can be placed on the table or floor.
These heaters have a high resistive coil element that heats up as electricity passes through it. A fan blows the hot air around the element out into the room. Heater fans include a variety of features, mechanical and digital thermostats, oscillation and programmable timers. All heater fans include overheat protection.
Utility heaters have all metal construction and are ideal for rugged environments like workshops, garages and basements. Standard features include a thermostat; overheat protection and tip-over protection for added safety.
These heaters use glowing elements that emit light. Like the sun, these heaters will warm the object in front of it. Many radiant heaters include a fan to help push the heated air out into the room. Standard features include a thermostat; overheat protection and tip-over protection for added safety.
