What does this oil-filled heater do?
This heater uses electricity to heat up the oil inside that is stored inside. That, in turn heats up the room that the heater is in.
Oil heaters, also known as oil radiator heaters, are modern electric space heaters with a twist. Rather than rely on a fan-forced system to expel hot air into the room, oil heaters like the AH-450B gently transfer thermal energy into the room by circulating hot oil throughout internal coils.
Why should I use this heater?
If you need a no-fuss heater that is portable, safe, and works fast, the AH-450B is a strong candidate. Because this heater runs on oil, it works quickly and efficiently to heat any room up to 300 square feet. It is also highly portable, with every convenience a heater can provide, like wheels, a handle, and cord wrap.
Where exactly can I use this heater?
The AH450B can be used in any indoor setting of 300 square feet. It is good for:
- Guest Rooms
- Underneath your office desk
- Next to your reading chair
- It is not recommended for garages, workshops, or any outdoor settings
This heater should be placed on a hard, stable surface. If you must place it on a carpet, add something more stable to place the heater on like a rubber mat, or even a large cookie sheet, as some creative owners have done in the past.
Pros of radiant heat:
- Very efficient
- Heat up objects in the room first
- Helps stabilize the temperature in a room better
- More quiet than convection heaters
Cons of radiant heat:
- Can only heat a small area
- Slight drafts would interrupt the heat
Pros on fan-forced heat:
- Units generate heat quickly
- Good for heating up large areas
- Gives off ambient heat (heats the atmosphere in a room)
- Fan ensures warm air fills the room
Cons of fan-forced heat:
- Fan makes more noise than radiant heaters
- Atmosphere of a room gets warm first, not people or objects
Heater Cleaning and Maintenance
How do I clean the AH-450B?

Using the Remote Control
How safe is the AH-450B?
This heater includes a safety tip-over protection feature which will shut the heater off in case it is tipped over. If, at any time, the heater does tip over, please put the heater back in the upright position (wheels on bottom, controls on top). The heater will resume its normal operation.
CAUTION: This heater includes an Overheat Protection System that shuts the unit off if it overheats due to abnormal conditions. At this time, the "C" Caution Indicator Light turns on. If this occurs turn the heater "OFF", unplug it, and inspect and remove any objects on or adjacent to the heater. Allow it to cool for a few minutes, plug it back in, and resume normal operation.
Do I need to refill the oil in the unit?
No. The oil reservoir is permanently sealed because the oil does not need to be refilled.
Does it get hot to the touch?
Yes. Please be careful when handling the NewAir AH-450B. Make use of the handle when maneuvering the unit while it is in operation.
Can I leave the heater on while I'm not in the room?
No. It would not be energy efficient for it to run when it does not need to be used, and it is also a safety hazard.
What is the temperature range?
65°F - 85°F.
How does the programmable thermostat work?
When you choose a preset temperature, the heater will sense the ambient temperature, and if the temperature is a few degrees below the set temperature, the heater will turn on. Likewise, if the room temperature rises a few degrees above the set temperature, the heater will automatically turn off.
When using any electrical appliance, including the AH-450B Oil-Filled Radiator, basic safety precautions must be followed in order to reduce the risk of fire, electrical shock and/or injury to persons or property.
Please observe the following safety tips:
1. This heater is hot when in use. To avoid burns, do not let bare skin touch the hot surface. If provided, always use handles when moving this heater.
2. Keep combustible materials such as furniture, pillows, bedding, papers, clothes and curtains at least 3 feet (0.9 m) from the front of the heater and keep them away from the sides and rear.
3. Extreme caution is necessary when any heater is used by or near children and whenever the heater is left operating and unattended.
4. Always unplug the heater when not in use.
5. Do not operate the heater with a damaged cord or plug, if the heater malfunctions, or has been dropped or damaged in any manner. Return heater to authorized service facility for examination, electrical or mechanical adjustment, or repair.
6. Do not use the heater outdoors.
7. This heater is not intended for use in bathrooms, laundry areas and similar humid indoor locations. Never locate heater where it may fall into a bathtub or other water container.
8. Do not run cord under carpeting. Do not cover cord with throw rugs, runners or similar items. Arrange cord away from high-traffic areas where it can be tripped over.
9. When transporting or maneuvering your AH-450B, make use of the power cord wrap at the front of the unit to reduce the risk of power cord related accidents.
CAUTION: This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician.
10. This heater draws 12.5 A during operation. To prevent overloading a circuit, do not plug the heater into a circuit that already has other appliances working.
CAUTION: It is normal for the plug to feel warm to the touch; however, a loose fit between the AC outlet (receptacle) and plug may cause overheating and distortion of the plug. Contact a qualified electrician to replace a loose or worn outlet.
11. To disconnect the heater, first turn controls to the OFF position, then remove plug from the outlet. Never pull by the cord.
12. No object should be inserted into any part of the heater at any time.
13. To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not use on soft surfaces, like a bed, where openings may become blocked.
14. A heater has hot and arcing parts inside. Do not use it in the areas where gasoline, paint, or flammable liquids are used or stored.
15. Use this heater only as described in its manual. Any other use not recommended by the manufacturer may cause fire, electric shock or injury to persons.
CAUTION: Avoid the use of an extension cord because the extension cord may overheat and cause a risk of fire. However, if you have to use an extension cord, the cord must be No. 14 AWG minimum size and rated not less than 1875 W.
16. The output of this heater may vary and its temperature may become intense enough to burn exposed skin. Use of this heater is not recommended for persons with reduced sensitivity to heat or an inability to react to avoid burns.
17. Before using the unit, check if the voltage indicated corresponds with the intended outlet (120V).
18. This heater may include a visual alarm to warn that parts of the heater are getting excessively hot. If the alarm flashes, immediately turn the heater off and inspect for any objects on or adjacent to the heater that may cause high temperatures. DO NOT OPERATE THE HEATER WITH THE ALARM FLASHING.
