QUESTIONS AND ANSWERS
If the heater cycles ON/OFF without heating:
Please note: This is a smart heater that monitors the room temperature and produces heat only when needed.
You can set the desired room temperature with the heater in either ECO HIGH or ECO LOW mode. (The factory default setting is 68 °F.) For an example of how the heater works, let’s say you set the temperature for 70 °F. Once the room has reached 70 °F, the heater switches off and the fan stops (Note: The heater remains on STANDBY as long as you do not POWER OFF). As the heater remains on STANDBY, it will read the room temperature every 4 minutes by running the fan ONLY for 60 seconds. During this process, the fan also blows out the residual heat from inside the chamber to ensure an accurate temperature reading of the room. If the room temperature is at 70 °F(or higher), the heater will remain on STANDBY. It will repeat this sensing cycle, reading the room temperature, every 4 minutes. However, if the room temperature drops 2 degrees lower than the set temperature, the heating function will turn the heater ON and the fan will blow warm air.
If the heater cycles but doesn’t produce heat for hours:
If the temperature is set lower than room temperature, the heater will perform only the sensing cycle and the heater will not turn on in the heating function. To have the heater turn on, always set the desired temperature higher (2°+) than the room temperature, or manually select High or Low to have instant heat.
How to turn off the heater:
Switch to STANDBY mode or POWER OFF the heater.
Does the blower cycle use much electricity?
The blower fan will run for 60 seconds every 4 minutes to clear residual heat inside the chamber, while at the same time measuring the room temperature. This does not use much power to operate.
Why does the blower fan keep running after I have pressed the power off button?
The blower fan will continue to run until the heat chambers cool down. After a few minutes, the fan will shut off automatically.
What if the heater’s airflow seems to have diminished?
Please ensure the rear intake is not blocked and that the filter is clean. Please follow the filter maintenance procedure to clean the filter.
Once the heater is turned on, how long will it take to heat my room?
This heater can heat up a large room. Remember that with any type of heating process, there are many variables such as the size of the room, how well the room is insulated, how many doors and windows there are, the amount of bare concrete (which acts as a heat sink with any type of heating), the opening and closing of an exterior door, the outside temperature, etc. Please remember that this is a zone heater and is meant to be used as a supplemental heating source only.
Can I use the heater to heat multiple rooms at the same time?
Keep in mind that heating will vary based on how open your floor plan is and the size of the rooms involved. We have heard from customers that with the help of ceiling fans, they have been able to heat multiple rooms simultaneously by placing the unit in a central room. We suggest you give it
a try and see what works best for you.
My home is not well insulated; will this heater help me?
Yes, but it may take a little longer to heat the room. The outside temperature will also have an impact on heating time. Once the room has reached the desired temperature, it will cycle on and off accordingly.
Can the heater be used in a bathroom?
It is not recommended due to a bathroom’s high level of moisture.
Can the heater be used in a basement or garage?
Yes, but keep in mind that rooms with little insulation will not retain the heat as efficiently. Bare concrete floors act as heat sink with any type of heating and will absorb some of the heat. However, placing the heater a few feet above the floor will allow for more efficient heating.
Can I use more than one heater at a time?
Yes, but please make sure the heaters are not on the same circuit. Each heater and the appliance should be on its own circuit.
Can I use the heater and another appliance at the same time?
Yes, as long as they are not on the same circuit. This heater is considered to be an appliance. You should not run more than one large appliance on a single circuit breaker. Your appliances, such as a freezer, refrigerator, microwave oven, washing machine, dryer, and others, should not share a circuit breaker.
Can I use the heater on a job or construction site?
This heater is not designed to be used in a high dust construction environment. Using the heater for this purpose will void your warranty.
Can I move the heater around while it is operating?
It is not recommended to move any portable heater while it is operating. We recommend moving the heater only once the fan has completely turned off.
What is the life expectancy for the heater?
This heater uses one infrared tube (which is rated for 20,000 hours and up), and one PTC element (which is rated for 80,000 hours and up).
What is zone heating?
Zone heating focuses on heat where people spend the most time. After all, there is no point in heating multiple rooms to +68 degrees when not in use.
Can I use an extension cord, surge protector, or power strip with my heater?
No. The DR. INFRARED HEATER is designed to plug directly into a grounded 120V 15 Amp or higher circuit receptacle. Never use with an extension cord or relocatable power tap (outlet/power strip).
How many kilowatts per hour does the heater use?
The DR. INFRARED HEATER MODEL DR-968H uses approximately 1.26 kilowatts per hour.
What is the BTU Rating for the heater?
The DR. INFRARED HEATER MODEL DR-968H is approximately 5200 BTUs.
The power cord feels warm to the touch; should I be concerned?
It is normal for the heater’s plug and cord to feel warm to the touch. A plug or cord which becomes hot to the touch or becomes distorted in shape may be a result of a worn electrical outlet. Worn outlets or receptacles should be replaced prior to further use of the heater. Plugging this heater into a worn outlet may result in overheating of the power cord or even a fire.
I don’t have a grounded outlet; can I use a cord adapter or remove the grounding plug?
NO. If you don’t have a grounded outlet, contact a licensed electrician in your area for advice. Removing or altering any part of the heater is unsafe and will also void your warranty.
