Is this unit energy efficient
1698768
I have had mine for 5 years and see no real measurable rise in energy costs. Liked this heater so much I bought a second one for a backup or replacement when my original one finally does give out. Use it primarily to heat our den which is a 20x20 room with 2 large sky windows and three other widows. Given time it heats this room very nicely and keeps the temperature well.

It is very quiet. It is much quieter than other small appliances. The impact on my energy bill is insignificant.

If your central heat is inefficient, you will probably save money using this unit. Warms up room its in nicely.

Don't buy this expecting it to be energy efficient. It will run your electric bill up. I am total electric and I use it on "flames only" most of the time for ambiance as it will easily increase your elec bill $20 to $30 a month if you use it often.

We have been running this unit constantly since April. We live on Long Island and the basements are all underground and damp if you do not dehumidify. This unit is perfect for us. Never turn it off and I have not seen any difference in our electric bill.

I agree with answer 1 and two. However I have had mixed performance with unit I would not purchase again.

Yes it does waste energy... well during the heating season the heat escapes with in your house so its not a waste. During cooling season it does waste energy. It doesn't waste a lot of energy. For many people it is cheaper to use this system than it is to run the water for 5 minutes to get hot water. It depends on the cost of your water... Since I got it I am saving about 50g a day. Which pays for it self. Also the unit has a timer on it this way it doesn't run at night. I have mine tied into my home automation so it shuts off when the house is not occupied. It really is nice to have that hot water ready to go! Yes it does waste energy... well during the heating season the heat escapes with in your house so its not a waste.

I love this unit, requires two 220V inputs from power panel. I have two ECO Smart units and save $80 a month on my power bill.

I cannot say it is energy efficient ??? but keeps the den habitable to enjoy and can lower the main furnace (electric heat) so not entire heater has to run as often.

No. My unit works well. We typically use it for 3 to 5 hours at a time to heat up our basement TV area.

It uses a reasonable amount of electricity. Last winter I went from oil heat to electricity only and my electric bill was less than 3 times the previous year during the coldest winter months here in New England.

This is a great unit with a small footprint. Very efficient and we love it for the winter months here in Central Florida. It is a wonderful value for the money. I do hope this helps you decide.

Are you sure the unit is set on "cool" and not just "fan"? I have done that before. Otherwise it must not be working right. We have our unit in a second house which I know dates back to about 1900, so it is not well insulated nor does it have energy efficient windows. The downstairs is 30' by 25', with four rooms that are all connected, so you can make a circle through the rooms. We have the unit in one room and a large fan in the opposite corner of the house to keep the air moving. We were just there and for 2 days with temps in the high 80's the EdgeStar kept the downstairs at 69-70 degrees. Are you sure the unit is set on "cool" and not just "fan"? I have done that before.

Yes it has energy saving functions. And it works very well. I have become very reliant on the thermostat. I set the temp (indicated on the LCD display) when the thermostat reaches that temp it turns off the compressor and only the fan keeps working. Has worked flawlessly in this regard. I set it to 74 degrees indicated, for example, and the AC compressor turns off.Another way you can save energy is by setting the timer (in increments of one hour). The entire unit turns off after reaching the designated hours used. (There's no clock timer.) I have the unit set up by my bed. On hot nights I go to bed, set the temp, and timer. When I'm asleep two hours later, for example, the machine turns off. Yes it has energy saving functions. And it works very well. I have become very reliant on the thermostat.

It is not too bad from a noise perspective. Mine runs in the basement almost constantly and is OK. If you spend a lot of time next to it the noise could be of concern. The unit is energy start rated but my electrical consumption has significantly jumped this year. Mainly because I have the drain hose connected to it so it runs much more than my old unit where I would forget to empty the bucket on a regular basis.

No I didn't notice anything about that. And I'm not sure how energy saving it is. I use it in a small bathroom.

I have used the purifier 24/7 for 6 months and am very satisfied. Although i haven't paid any attention to the energy consumption, I would think it fairly normal for a small appliance.
