Questions & Answers
That is an excellent query. The heating element is made of ceramic. A PTC heating element is typically used in ceramic heaters to generate heat. The ceramic is a semi-permanent material. When a voltage is applied, the power rapidly decreases as the material heats to a specific temperature. The ceramic's composition determines the temperature - making it self-contained governing - as well as providing a built-in advantage in terms of safety. So, while nothing explicitly states that the heating element is ceramic PTC, it is a ceramic element, and the material - by definition - is ceramic. It's a part of the PTC system.
Hello, br>It's not a set timer, but it will turn on based on the temperature in the room, just like your home's heating/air conditioning unit. off, but not entirely off
It will continue to cycle. off . Depending on the temperature you've set. Exactly like your home's heating system. If it keeps you awake, you must be one of the lightest sleepers on the planet. It is extremely quiet when in use.
So far, ours has served us well for about a year. It draws approximately 1,147 watts on high and 1,136 watts on low, according to a "KillAWatt" meter. The only difference appears to be the fan speed on the hi setting, which is higher/faster than the slower/quieter fan on the low setting. I wish the low setting had a lower wattage, but it does not appear to be the case. At least, that's what I've been able to verify with my meter.
Selected User Reviews For Lasko 5309 Electronic Oscillating Tower Heater, Digital Controls
The majority (if not all) appear to be using the same temperature controller, which was most likely manufactured by a single source or based on the same design drawings. None of them have had any sort of precise control, and the majority of them aren't even functional. Some will not turn off at a predetermined temperature or numerical value. Some units refuse to turn on in temperature controlled mode, and others have failed by overheating to the point where plastic parts have melted and a fire has been threatened. br>br>This Lasko 5309 unit is no exception. It won't turn off if the temperature is set to 70 degrees Fahrenheit. Increasing the temperature of a small room to well over 95 degrees Fahrenheit, as well as the unit's body, The fan is turned on when the temperature is set to 65 degrees Fahrenheit. The heating element, on the other hand, does not work. br>br>The manual mode is the only way it can be used safely. with a person turning it on and off all the time br>br>It astounds me that any of these units are approved for sale by government agencies in charge of product safety. It also astounds me that retailers are willing to sell such defective devices and put their customers in danger for the sake of a few dollars. br>br>Only because it turns on do I give the unit two stars. heats things up However, I want to emphasize that the temperature controls are ineffective, potentially dangerous, and are found on virtually every space heater currently on the market. br>br>There is one unit for which the temperature-controlled mode operation is described in such a way that it is clear that the controller is unique. I've placed an order for one of these units and will conduct a review to see if the design and operation make it safe and effective.
oscillation (noun) Pro's: Ceramic is more appealing than most, and the oscillation helps to distribute heat throughout the room. It also has a longer electrical cord than competitors. br>br>Contrary to popular belief, there are a number of disadvantages to using this product. Heat seemed to stay contained within the device rather than being pushed out into the room when set to 80F in a 55F room and not oscillating. br>br>Even though the device had been running for an hour, I needed to stand in front of it right away to feel warm. That's when I decided to experiment with the "oscillation" setting. It was a significant improvement. In a matter of minutes, the room was warmed up. br>br>This replaced a Holmes heater that had been in use for over 20 years. Regrettably, that model has been discontinued. I had previously purchased a Holmes product that provided excellent heat, but the cord was too short to reach the area I needed to warm. As a result of using a heavy-duty indoor/outdoor extension cord with that device, the heat generated by the device began to melt the extension cord's "outlet" where the device was plugged in. (The heater had become so melted that unplugging it from the extension cord was impossible. ) - When looking for a replacement, keep in mind that all of the small portable ceramic heaters come with instructions to avoid using an extension cord and to instead plug directly into the wall. Because the Lasko's electrical cord is slightly longer, it is possible to heat a desired area while also safely plugging it in. within the apparatus.
I tested this thing extensively in the location where it would be used before I was willing to trust it. This will be my second winter with it, and it continues to perform admirably. Because of the heated wire behavior described below, I deducted one star. br>Heater is very quiet and does an excellent job of heating a small area. After several hours of running in a 270 square foot bedroom, it barely heats the space. After only about 10-minutes in a 70 sq ft bathroom, it heats up quite a bit. It will take 15 minutes. br>br>While running on MAX, the cord and plug heat up gradually but noticeably. It never gets hot enough to cause me concern, but the fact that it heats up at all makes me suspicious that something is wrong; however, it could be that it's simply conducting heat back from the element, in which case my concern and docking of a star are unfounded. br>The wire appears to be Unirise branded 16AWG UL listed heater wire, which puts the ampacity just above the 12. The load is rated at 5 amps. It's not small, but there's not a lot of room for error. The wire size isn't the cause of the heat unless the heater isn't working properly and drawing far more than it's rated for. br>There is no ground, but it does not appear to be necessary given that the heater is mostly covered in plastic. br>br>Make sure the circuit you're going to use is up to the task! In a single room, it's not uncommon to find four receptacles fed by a single 14AWG wire. You can easily overload the circuit if you have a television, computer, aquarium lights, and other electronics on the same circuit as the heater running at maximum capacity. It's not worth the risk when verifying takes only a few minutes from anyone who is willing to read or watch a video.
Overall, this heater does not perform as well as the previous model, but I have yet to write a review. Last December, I purchased this fan to replace an older model that had finally failed. It has served me well up to this point. However, in the last few days, I've had to deal with a potentially dangerous malfunction. I turned on the oscillator and set the temperature to 70 degrees Fahrenheit. It stopped oscillating after a few minutes when the setting was changed to "Max"! It became extremely warm. Because it would not turn off properly the previous two days, I simply unplugged it and tried again the next day. The controls were unresponsive, and it happened again the next day. I tried unplugging it, waiting a few seconds, and then plugging it in again today. As soon as I plugged it in, it turned back on! I then purposefully knocked it over to see if it would turn off (as it should). It didn't work! This is a critical flaw that must be addressed, and I am writing to the company to request that it do so.
