Question: How much more is your electric bill using this heater?
Document: As of yet don't know how the electric bill will be. I can tell you our home has never been more warm and comfortable as it is now. We are elderly and this comfort was much needed. We have bought infrared heaters for our daughter, grandson, granddaughter and had one shipped to elderly friend in Texas. They love their heaters. I also have one of the portables that sits on the dresser in guest bedroom. Already checked it out and it warms bedroom perfectly.
This heater saves big $$ when it comes to our electric bill. We had a really cold winter and this helped out big time.
I think the product is great. There was no spike in my electric bill like ceramic heaters. The thermostat is able to set a temperature I want. The only thing I am not crazy about the heater is when it reaches temperature, to cool down it blows cold air.
I had left the main heater at 50 and it was about -10 degrees outside. Im sure if you were to buy two or three of these it would heat a average sized house just fine. We saw about a 30 dollar increase in our electric bill every month that we used it consistently Feb-april.
I run this unit about 8 hours a day, and my electric bill is only about $10 more per month.
We have a heat pump system that doesn't work well in extreme cold weather this cut our electric bill in have heats so well glad I got this great quality
nice looking heater havenot had heater long enough to say much about it-seems to work ok-will find out over time
This heater is nice and would have worked perfectly, if the fan did not run so long after the heater turns off. When the heater is off, and the fan continues to run, it cools the room that it has just heated. My understanding from the instructions is that the fan runs in order to distribute the rest of the heat, but as I stated above the fan runs much to long, and it only does the opposite, which is cool the room that it just heated.
I ordered this Heater early in the winter season after using a different brand a few years ago. They are in the basement awaiting transport to a &#34;fix it&#34; person in hopes we can get them working again for someone else that may need them.We love Lifesmart and this particular Heater - this is perfect for us. In what little did we know was going to be the worst cold we can remember this Heater has done it's job and then some.
My husband and I love our Lifesmart Infrared Heaters. They are energy efficent, reasonably quiet and take up very little space. They are safe for our smallest great grandchildren and pets. the filter is easy to clean. It will be much cheaper than the propane we buy for our central heat. Several years ago we bought our first infrared heater not knowing anything about them. Found out how efficient they were and bought another.
Answer: 50 dollars a month more.
