Understand And Knowledge Ac and Power Efficiency Ratio (EER) Reviews

Lightweight Air Conditioner Productivity Data Page 

Each air conditioning equipment comes with an energy-efficiency ranking that lists how many BTUs per hour are used for each watt of power it brings. For room air-conditioners, this rating could be the Energy Efficiency Ratio, or EER. For central air conditioners, it is the Seasonal Energy Efficiency Ratio, or SEER. These ratings are published on an Energy Guide Label, which should be linked in a place on new air-conditioners. Many ac companies are voluntary participants in the Energy-star labeling program. In case people hate to identify further on [http://thewaterblog4.webs.com/buy-a-water-softener go], there are many libraries people should consider pursuing. EnergyStar-labeled appliances signify they've large EER and SEER scores. 

How is EER Calculated? 

The EER of an air-conditioner is its British thermal units (BTU) standing over its wattage. As an example, if your 10,000-BTU air conditioning equipment consumes 1,200 watts, its EER is 8.3 (10,000 BTU/1,200 watts). The higher the EER is, the more efficient the air-conditioning unit is. However, usually a higher EER is accompanied by a higher value. 

Would the Higher Portable Air Conditioner EER Status be Worth the Excess Cost? 

Let's say that you're offered a choice between two 10,000-BTU air con units. One has an EER of 8.3 and consumes 1,200 watts, and another has an EER of-10 and consumes 1,000 watts. Let's also say the cost difference is $100. To assess what the payback period is on the higher priced device, you must know: 

1. About how many hours annually the unit is going to be operating 

2. What-the price of the kilowatt-hour (kWh) is locally 

Let us say that you intend to utilize the air-conditioner in summer time (around five months a year, according to where you live) and it'll be running about 8 hours a day.

Let us also say the cost-of a kilowatt-hour in your area is about $0.10. In case people claim to learn more on [http://reverseosmosiswaterfiltrationsystem.wordpress.com/hard-water-treatments/ return to site], we recommend many databases you might consider pursuing. Visiting [http://yourwaterquality9.wordpress.com/hard-water-treatment-options/ clicky] likely provides suggestions you can give to your dad. The difference in power use between the 2 units is 200 n, meaning that every five hours the less expensive unit will digest 1 additional kWh (and consequently $0.10 more) compared to more expensive unit. 

Assuming that there are 30-days in a month, you find that through the summer you're operating the air conditioner: 

5 mo. x 30 days/mo. x 8 hr/day = 1200 hours 

[( 1200 hours x 200 t) / (1000 watts/kW )] x $0.10/kWh = $24.00 

Because the more expensive unit costs about $100 more, this means that it'll take about four years for the more expensive unit to break-even. 

Consumer Beware! 

Not all BTU reviews might be trusted. Because the BTU's are said to be high on specific air-conditioning units, it doesn't mean it's necessarily true. Some companies will exaggerate the BTU's o-n devices to raise the likelihood of attempting to sell the them and the others will be more conservative in regards to the BTUs, which will cause the EER rating to be lower therefore a lower portable air-conditioner EER may be misleading. It is best not to permit the EER energy score to be your only criteria for choosing an air conditioning system. Do the research o-n what-ever uni-t you're considering for your house and you will be happier with your purchase.
