Is this more efficient than two separate units would be on energy consumption?

16 SEER is the efficiency for this model. Efficiency is same as any single 16 SEER unit. Actually all that depends on how you utilize them, your climate, and a thousand other factors.

Hi, new guy! One is dedicated intake, one is dedicated output. It makes the entire closed system more efficient. Google AC one hose vs two hose, and you will likely get more educated answers, but I hope mine helps. Two is well worth the money, over time.

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 would say yes because they are also running a fan plus the elements,but I don't think it's that much more power being used to run the small fan.

If you don't use everything all at once. Mine runs one bath, kitchen and laundry, I have a small unit for second bath. One thing to check out first would be the electrical power required and it's availability. Requires three double 40 amp breakers and heavier gauge wire to carry the power. I took out a 40 gallon electric water heater and it has saved me about $60 a month so I would not go back. As energy prices get higher I save more. As with everything some common sense in using it should be observed, I love mine.

I really think it's less use of electricity than if you used the oven - it's faster and I put mine in the garage so the house isn't heated (no extra use of AC?) It may be just what you have to do today if you want dried products instead of hanging them in the sun like our forefathers did.

Theoretically it is 3% more efficient in its use of power. Realistically you will notice no difference. This power supply is a pure luxury supply. There are more powerful, cheaper supplies, but this one is built like a 1970s Mercedes Benz. Rock solid luxury, for a price.

One stores more energy that the other, it could be a hour or more extra time depending on your use. :)

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.

Yes it is quite efficient. However it does not heat as large an area as indicated. We purchased it for our basement which has no other heat source and it only raises the temperature 2-4 degrees. It does work really well in a room about 12/16.

When I do my homework the edv used more energy than compressor dehumidifiers. But edv's are nice and small compared to a regular dehumidifier.

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!

I don't know if it is an energy efficient product or not...but from what I have read a lot of companies will put a small motor in so it WILL be energy efficient, but as it is a smaller motor, it will make more noise (humming etc). This fan is pretty quiet which is my main concern as it is in my bedroom and I keep it on at night. I think you really have a choice between quiet and energy efficient but not both. I think for the most part they are all fairly efficient with not a big range of difference.. My two cents anyway !

We installed one unit to cover an entire church building. Since the whole place is heated by one boiler we just picked the room with the lowest temperature. If you have separate heating systems involved, I don't see why you can't use more than one.

I honestly don't know. I purchased all individual units. I would think that both units would heat up so it might not be a good idea to leave one empty.

The manufacturer requires three 40 amp double pole breakers for this water heater. Having said that, the true power consumption is quite low. To explain, I will give you my observations while the unit was in use. The unit has three 9 KW heaters. All the heaters do not operate at once. The first heater begins to modulate at low flow rates. If the flow increases and the first heater has reached maximum voltage then the second heater has voltage applied to maintain setpoint temperature. If the flow increases further then heater number three begins to operate as well. During my tests I never saw all elements on at the same time. As an example: a kitchen faucet, bath vanity, bath shower and a washing machine filling resulted in one element at full power and the second element was at half power. This was with the incoming water temperature was at 70 degrees F. Lower incoming water temperatures does degrade the efficiency of this unit. Remember this heater does not use any power until a faucet, shower ect. is opened for hot water. My heater has been in operation for two years with zero issues. In summary, if I needed a water heater today I would purchase the exact same thing.

It is more energy efficient than other electric models since its motor only draws 6.5 amps, while others are often double that. As far as impact on electric bill, it's negligible.
