Is this heater energy efficient?

The Bionaire BH3950-U heater is not energy efficient, they are in the $300 plus range. This one takes awhile to heat up. It also, depends on the outside temperature. I would say, that in a 10'x20' room, with a outside temperature of 20 degrees, I feel it would take 2 hours to feel it. It is quiet.

It started leaking oil after only about a month of use, so the company refunded my money. I previously had a different brand that lasted for years and worked well for heating a room. I won't buy this type again though.

Resistance electric heat is not an energy efficient means of heating a large space: i.e. central eating. But used for heating a small space, instead of turning on the central heating, it can be. For example I keep a small electric heater in all bathrooms, which makes life pleasant with minimum use of the main furnace. This works well for me. This particular heater, however, (at least the one I have) produces an unpleasant odor. So I would not buy again.

I am not going to say i have not seen a increase in the power bill, but it could be worst, also i was not aware it had oil inside it, actual thought these series of flat bars were the heating element, i agree it is silent as it does not have a fan, before i purchased it the review said 1,000sf and i have been using it in the downstairs living quarters and sits only feet from my bed, but i also have the furnace on at 74 degree, so its hard to pinpoint how much is the furnace and how much is the heater. If this is any help, i have closed the vents and turned the heater up to max and was a bit to warm..

My heater has been great so far. I've owned it for about a year and use it to heat my family room (20 x 13 ft). It keeps the room quite comfortable, but don't know how much energy it actual uses---just know that I rarely have to turn on my house heater which saves money.

This is the 2nd winter for me having this product. It is lightweight, slient and easy to move from room to room.It will keep rooms warm that are 12 x 10 or smaller. And, yes it is energy efficient. I am extremely happy with this item. Hope this helps in your decision making.

I can not answer this precisely as there is no way to measure. However, I believe that it saves energy overall because we can heat a certain area of the house without having to turn up the thermostat thereby heating the entire house. We use it primarily in the family room while watching TV. It is completely quiet so it does not intrude.

Yes it is, quite efficient. I keep it on the low setting about half way on the thermostat and it heats up my bedroom quite nicely. It's a very large bedroom as well. We have two of these heaters and our electric bill doesn't go up too much. We use these to save on heating oil, which is way too expensive.

Can not compare to ecoheater but it is well known they get hot, these envi heaters do not get hot enough to cause trouble. I do find them very inefficient, they can hardly keep up with the rest of the house. To cut bills on heating you would need at least one for every room in the house and not just the colder areas.

Sorry I can't answer that, I guess that depends on the room size. Go here to see if it helps: http://www.wisegeek.com/how-much-energy-do-space-heaters-use.htm On the menu at the top you can click "best space heaters" and see what they say.

Most of the efficiency is lost with the surrounding (lack of insulation), it has very little to do with the heater itself. With its effective air circulation, this heater is as efficient as an electric heater can be. That said, this is a beautifully put together, quiet and effective space heater.

I own two of these heaters one purchased on 2010- it is now on its fifth winter and the newer one (2012) on its third winter, in use in my bedroom. I needed one left mostly on 400 watts (the top rod) and sometimes on 800 watts - aimed towards my outside wall in my laundry room to prevent frozen pipes. It is on 24/7 and I have had NO problems with either of them and simply store them in the box they came in when I warm up. HIGHLY recommended.

No, the heater did not save energy. It is more expensive than gas heat. However, in the cold room where we used it we could not get heat from the furnace in that room without a heater. For one year it gave good heat, then it broke down. We paid shipping and handling to get it fixed. It never worked well again.

I have not looked at my electric bill, but since it has a timer and auto shut off. The heater won't be on when it does not need to, I guess that will do save me some money.

It is a fan forced unit. It will blow out about 8 to 10 feet. This heater is quit a work horse. On high it really heats quick. On low it will maintain. Not sure what the power consumption is yet, as we have only had this heater about one month. Hope this helps.

I wouldn't say it's more efficient with or without it. I find it heating in a similar manner.

I don't know a number, but if you have central heat, it will be more efficient than this heater, which is also electric. I did not get to keep mine long enough to find out if it was efficient. It quit working in less than a month, and they sent me a replacement part. I am not an electrician, so I couldn't repair the unit.

I think it is a trade-off... Our main gas furnace does not come on as much, but the room the little heater is in is much warmer than it is using the gas furnace alone. In the end I think the electric bill goes up a little and the natural gas bill goes down a little. This being said, I liked this heater so much though, that I bought another for a different place in my cold Michigan house.

It runs at 1500w. From my prospective it eats up too much electricity bc there are some heater just costs as low as 600w with similar output

No where is it written in the package insert that this heater is energy efficient. So I doubt that it is. However, there is an "EC" setting (Eco-Smart) on some Sunbeam heaters. On this setting the heater cycles between high (1500 watts) and low (750 watts) to conserve energy. My heater is packed away for the summer months, and I do not remember if the EC setting is available on this particular model. Sorry I couldn't give you a definite yes or no answer.

V.Alden--I don't know, but I too am interested in efficiency per kwh. No one seems to address that issue in the reviews. I'm looking for a safe and efficient electric heater for my daughter's bedroom in her first apartment. I'm looking at this ceramic heater because it has good reviews and lots of them, and ceramic is supposed to be efficient. I like quartz heaters too. I'm trying to figure out which is best to keep the electric bill lower.

I have used this heater to heat a small living room and kitchen but it uses a ton of electricity as any electric heater will. The kitchen and living room is probably half of the total 1024 sq ft of the house. I used it for a few months in southern Maryland during the winter, my electric bill was usually $40 more just because of that heater. I haven't used it since last year but do recall when it cycled on, the lights would dim/flicker. It has 2 modes 900 watt and 1500 watt and I only used it on the 900 watt mode. I would guess it may ok for a bedroom only, as long as it was closed off.

It is no different than any other heater with a thermostat that is set to the same temperature. ALL electric heater marketing that suggests a product is more eco or efficient is deceitful. They all convert power to heat with the same 99.999...% efficiency. The difference in price should account for a style, features, safety (room placement or reduced exterior operating temp or less likely to tip over if pets or children are in the area), or lifespan improvement that's important to you.

Hi,Yes this unit has the capability to power the items you've mentioned, but it will simply be a matter of how long and that will depend on the rate of energy being used by the device being powered, a small electric heater has a rather high rate of energy use. Keep in mind the unit is rechargeable, it's a battery based power source, it's extremely portable and quiet. Hope this helps.All the best, Electrovicity
