How efficient is this unit? I read somewhere that its EER is 8.2 which is not very good since I understand that 10 is what many quality units boast.

I'm sitting here in my room writing this while the unit is on, and I'm cooling down after sweltering in 90+ degree heat that the rest of the house is melting in. So, I'd say the unit is very efficient. This is my second summer with it and it hasn't disappointed me yet.

To calculate the Electric Efficiency Rating, divide the BTU per hour (which is 8000) by the watts (which is 900), so for this unit, the EER is 8.89, which is not very high, but then, there are other advantages to a portable which may help offset the mediocre efficiency.

I do not remember 10 yeaqrs specificly. I do remember that it had a reasonably long guarantee at least 5 yers and that it did have the reputation to be one of the most relieable units on the market, so far so good. The less complex electronics are the more reliable. I am happy with mine.

We have been very happy with the unit and are considering getting another one. I haven't used other makes/models so I can't give you a comparison.

I measured it once with a meter... I can't remember all that well (measured it when I got it last year).... I think it is around 80-85 dba within 1 meter of the unit (according to my decibel measuring device)...... but certainly less in the fuel conservation mode.... it is not too bad.... similar to most units ... maybe more but not as much as some of the older units... I like it and I am always concerned about the dba....

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 got the 18k unit as well, we used 10 ga.... 10 3 with ground (whatever that means)

I don't have the SR100 or SR200, for outdoors, the SR300 gets an 8 (it really is good outdoors), indoors I give it a 6. It's a bit unfair to include an HD unit in the scale, so 8 might be a bit much, but I'm going to say it's fair.

I'm glad you brought that up. I can't explain all that mumbo jumbo. Perhaps it had a little to do with the translation from Chinese to English. Who knows, but 15A works. What I can say is it does the job. That's all I care about. Buy it, don't buy it. Either way it has served me well. The machine has paid for itself many times over.

I have installed several of these units and have had no problems with -10 or 110, they seem to be a pretty good unit.

We have 2 of these units in which 1 runs almost all day and i haven't seen any difference in my megawatt usage! I was just looking at my NYSEG Bill and we're using less energy than we did last yr at this time! You'll love this unit! It can handle 3500 sqft and as long as you clean the filters once a month it runs with no problems! Had ours for 2 yrs and it handles pet odor, smoke, and cooking odors! If u check his website i think he's having a clearance of last yrs models BOGO Awesome Deal!

Low settings will work for you. This product is of consequence as it relates to indoor air quality. I have 8 units and love the performance.

It works ok, better with more than 1 unit. it depend also on how good your camera is. like how wide your lens can open( 2.8, 1.8,..) how high your ISO can go with out breaking up. Normally i cans go as far 10 feet with 1 light.

Hi:I have purchased three of these units for our church.I have two in the sanctuary and one unit in a classroom.They all work great, and it is a real bonus having heat and cooling in one unit.The temperature has been down to 10 degrees here this winter, and they are the only source of heat.I think the efficiency goes down as the temperature drops below 45 degrees, but they continue to heat the area fine.They offer two sizes based on the square footage they can service, so make sure you get the one recommended for you size area and it should work great for you.

I have used it on occasion but since I live in So California it doesn't have to work very hard. I also have solar electricity so I generate more than I use each month creating a negative usage with So Cal Edison. So I can't really answer your question. We do like the unit very much.

E.E.R is an energy efficiency ratio (for this model is 10.8,which is very good ) plus it does have a clean air ionizer. Actually it's working excellent , has a lot of great features. For the first time I am really happy with this purchase. Good choice. Advice for buyers : don't skip on the extended warranty. It's really cheep but will give you a peace of mind.
