Question: How much will be added to my bill if I use only 4-5 hour per day?
Document: So, if I use it if for three hours per day that would be 135 kilowatts per month and cost $18.90/month. A fair price to pay for added comfort in an area of the home we don't need heated full-time.
We recently finished our 14x42 foot basement with 9ft ceilings. While we have a couple heat vents down there, but it's always about 4 degrees cooler than it is upstairs (where the thermostat is located). We've been using this heater for a few weeks now. It's silent and heats our relatively large area quickly. The basement goes from 65 degrees up to 69 (that's where we like it) in well under an hour (20-40 minutes). It uses 1500 watts per hour. In my area electricity is about 14 cents/kilowatt.
If ever a product deserved a one star review it is this one.I purchased two of these at the same time to use in my kids rooms to keep them a little warmer at night during the winter months.The first one worked for two weeks then inexplicably began turning itself off after 5 minutes. I tried resetting it per the manufacturers instructions but it continued to run for no longer than 5 minutes before it would go into protect mode and shut itself off.The second one worked for three weeks before it had a fault that caused it to bypass the set temperature and run continuously all night!
I live in a cozy condo in Silicon Valley, however, it is not new/renovated since it was built in the 60s and has poor insulation. During the winter, it dropped to 32 degrees outside, but it felt colder inside our living room. Enough about creating a backstory.Overall, this heater saved my life. I would set the temperature to 68 degrees in my bedroom, and in less than an hour, my entire room felt like a perfect day in my hometown of San Diego. It definitely doesn't take up any space.
This 4 degrees may not seem like much but it is really noticeable on a cold night. It looks like quite a few heaters do the same and I don't understand why they can not make them go on and off with a 1 degree difference instead. With all that said it really does help keep the room warm if you can live with the minor problems.
This heater does its job if you close the door of your small room. My problem was that it does take up to much electricity and sadly I did not know this until I got my electric bill. It does have a timer and you can set the temp you would like.
Being able to see it in the dark is such a huge improvement, something you never really think about until you don't need to turn the light on to see the current temperature.When strategically placing the unit (i.e., in front of your drafty window) it heats up the room in no time! It probably goes from 65 to 73 in a matter of 30 minutes or so. So what I do with it, now, is turn it on about a half hour before bed time (since I keep mine in my bedroom), set the timer for an hour, come to bed and let it shut itself off after I've drifted off to sleep.I haven't noticed a change in my electric bill, but with it's quick ability to heat up the room, it makes leaving the heater running an unnecessary chore.It was a hard decision choosing between the trusty old Honeywell replacement or the Lasko, but in the end I definitely recommend the Lasko.
Don't get me wrong, it IS hot but just about as hot as a hot cup of coffee. You can touch it for about 2-3 seconds and be okay. This is great since it wont damage little kids and/or pets. Sure, kids will probably cry but it's no where hot enough to do any serious damage...but definitely hot enough to teach them not to touch the unit when it's on!- There is a safety mechanism that will turn off the heater if it is tipped over.- Aside from the LED display, the heater does not produce any sort of glow.- No fans and 95% silent.- My bill went up about $18.00 last month when I have the heater on 6-7 hours a day so it's really not that bad.Cons:- If your room has a high ceiling, these will take forever to heat up the room.
Broke after 1 hour of use. I think the switch or controller or whatever exploded. Something was rattling around inside.
This heater does its job heating up the room but its much noisier then the other reviews say. It is far from being silent. It makes a loud buzzing noise when it kicks on and is running. It also seems to be costing more then I anticipated to run. I have only used it for about a month and a half so far but my electric bill jumped up about $12 a month with no other changes to explain the increase. One other thing I do not like is that it will run until it is 2 degrees above the set temperature before it kicks off and will not come back on until it goes 2 degrees below the set temperature.
Answer: It uses 1500 watts per hour. In my area electricity is about 14 cents/kilowatt. So, if you use if for three hours per day that would be 135 kilowatts per month and cost $18.90/month. I use it to help heat our finished basement (14ftx42ft) and it does a great job. It's not cost effective to have it on all day long, but if I know I'm going to be in the basement I'll set if for 3-4 hours. It'll take the temp from 65 degrees up to 69 in well under an hour (more like 30-40 minutes).
