The description says infrared heater heats up objects, not air. Yet this unit has a fan to distribute hot air. I see a contradiction here.

Amazon Customer has the right answer. In the comments below his answer he (or she) elaborates. I'm a retired EE.

As another user pointed out in their review there are actually 2 electrical resistive heating coils in the unit besides the one quartz tube. The fan would be required because it has those 2 electrical resistive heating coils.

As far as I know, they all have fans, including the top-of-the-line Eden Pure!

There are 2 factors: The infrared heat is reported to be 250 degrees inside the heater and the fan is used to blow that heat out.Second factor: this heater has 2 types of heat: infrared quartz bulb and a PTC element (PTC = Positive thermal coefficient) usually made of an advanced ceramic material. The heat from the PTC element needs to be blown out.

A normal infrared heater heats whatever is right in front of it, not the air in the room, though it WILL heat moisture that is IN the air. The higher your indoor humidity, the more heat you'll actually see from an infrared heater. Mostly, though, units like these throw infrared radiation onto a heat exchanger which is quartz wrapped in metal, right in front of the infrared bulbs, inside the heater. THAT is the object that the infrared part heats, then a fan blows heat off the heat exchanger(s) out into the room. That's why these units only put out heat in the 110 degree range, though they put a lot more heat, probably more like 250 onto the actual heat exchanger itself. Also, these heaters and the iLIVING heater which seems to be a direct copy, have an additional PTC element, which is an infrared-ceramic arrangement. That is the source of the extra heat these put out using the same wattage. Most 1500-watt heaters have a 5,000Btu output, and a few are 5100, while these are 5200.

Because it is a 1500 Watt heater, it puts out about 1500 Watts of heat. All the "quartz/infra-red/radiant" is a bunch of B.S. ALL 1500W heaters put out about 1500 Watts of heat - or around 5K btu's. Do you think 5k Btu's will heat 1,000 square feet? At what outdoor temperature? At what insulation level? How much infiltration? Face it people, a 1500W heater is a 1500W heater! Fans make make it seem warmer faster, but in reality, A 1500W HEATER PUTS OUT ABOUT 1500W! Certainly not MORE than 1500W's, ever!

There really is no heating from this unit.That part of a feature of the unit is a misnomer. M

I gave this item as a gift, so I do not know if it uses infrared heat. Suggest you ask the manufacturer.Sorry I could not answer your question.

There is no fan on the heaters, they work by convection meaning the cold air enters the bottom of the heater and the warm air exits the top. If the heater is sized big enough for the room there won't be a need for a fan. The natural movement of the air will heat the room.

Understanding how the heater works: the infrared heats solid materials such as walls, carpets, or skin, which in turn warms up the environment. The constant motion you describe would mean that the infrared is not focused long enough on an object to heat it up. This idea would work much better (though much less safely) with a coil heater, kerosene heater, or something else that was designed to heat the air.

Yep, it is only a 200 watt heater... blows cool air in my opinion. .. we have two of them.... both the same... we are returning one... ones without fan are 10X the drying /heating power. Regret the purchase

yes it does. It gives off a soft heat, not like most heaters that blasts heat and dispences to the ceiling. Works best when it really cold. Not when its mildly cold.

The fan is necessary to move the air through the ceramic wafer. Without the fan running, if its' fuse doesn't melt first, and shutdown the heater; then you will spend a lot on electricity, for very little heat. The fans on these units only last about a season, if you use it regularly. The model here has a rotary motor on bottom, of the two I have had, they do not last even a season. A better model, is the one without the bottom part; and, you gain a knock-over switch, which is important!

No. It's sold or made by 'Mr. Heater', but it actually not a heater. Its just a ceiling fan/ light.

It is not a heater @Barry_Bloom it is a dehumidifier, technically it's suppose to dry up humid places. Thus the name "De-humidifier". It can alter the temperature in the humid area due to removal of moisture in the air, but it does not mean it will warm up the air like a heater. All in all, this dehumidifier specifically will not warm up the air. If you are lucky enough maybe the dehumidifier will do the trick and dry up the place it is in; as for me unfortunately this dehumidifier did NOT work well for me. It had very disappointing results.

The ZappBug Heater has one heater (the red square box in the product picture). There is uniform temperature in the unit due to the way it is designed, including several vents around the sides that allow for air circulation and even distribution of heat.We hope this answers your question.-ZappBug

It does not blow warm air. It is only a warm surface so it would not warm a room, only your feet.

Joann, as far as I know its built into the heater, I HAVE AN OLDER MODEL AND MY FRIEND HAS ONE LIKE THE PICTURE SHOWN. BOTH UNITS CAME with fans.

To my knowledge humidity is not a factor. Infrared heaters are humidity neutral.

Yes! Since My purchase and the problems I had with my unit and customer service, I found out that the unit is actually NOT infrared at all! It's no better than a heating pad! This company didn't follow thru with promises made to me either. I do NOT recommend anyone deal with this company.

Its a fan. It circulates the air. Its not a heater, or A/C unit. It moves the room air.

I would say that it is not normal unless you are trying to heat too much space. My Dr. infrared heater kicks on an off as it reaches the temperature set on the thermostat. I have noticed that if I try to heat more than one room it will not kick off because it cannot get the temperature up in that larger space.
