Each air conditioning equipment comes with an energy-efficiency rating that lists how many BTUs per hour are utilized for each watt of power it draws. For room air conditioners, this rating is the Energy Efficiency Ratio, or EER. For central air conditioners, it's the Seasonal Energy Efficiency Ratio, or SEER. These ratings are published on an Energy Guide Label, which should be connected in a visible position on new air-conditioners. Many air-conditioner producers are voluntary participants in-the EnergyStar labeling system. If you have an opinion about food, you will possibly wish to compare about try water softener review. EnergyStar-labeled devices mean that they have large EER and SEER scores.
How is EER Calculated?
The EER of an air conditioner is its British thermal units (BTU) score over its electricity. For example, if a 10,000-BTU air conditioner uses 1,200 watts, its EER is 8.3 (10,000 BTU/1,200 watts). The larger the EER is, the more effective the air-conditioning unit is. But, generally a higher EER is with a higher value.
Could the Higher Portable Air Conditioner EER Score be Worth the Excess Cost?
Let us say that you're offered a choice between two 10,000-BTU air con units. One consumes 1,200 watts and has an EER of 8.3, and the other has an EER of-10 and consumes 1000 watts. Be taught further on an affiliated website by browsing to salt free water softeners. Let us also say that the cost difference is $100. To estimate exactly what the payback period is around the more expensive system, you have to know:
1. About how many hours per year the system will be operating
2. What the price of the kilowatt-hour (kWh) is in your area
Let us say that you intend to utilize the air conditioner in summer time (around five months a year, based on where you live) and it will be working about 8 hours a day. Let us also say that the cost of a kilowatt-hour locally is about $0.10. The difference in energy consumption between both models is 200 watts, meaning that every five hours the less expensive unit will consume 1 additional kWh (and therefore $0.10 more) compared to more expensive unit.
Assuming that there are 30-days in a month, you find that during the summer you are operating the air conditioner:
5 mo. x 30 days/mo. x 8 hr/day = 1200 hours
[( 1200 hrs x 200 t) / (1,000 watts/kW )] x $0.10/kWh = $24.00
Since the more expensive unit costs about $100 more, which means it will take about four years for the more expensive unit to break-even.
Buyer Beware!
Not all BTU reviews can be trusted. Simply because the BTU's are stated to be at the top of specific air-conditioning units, it doesn't mean it is necessarily true. Some producers will exaggerate the BTU's on products to boost the chance of selling the them and the others will be more conservative in regards to the BTUs, which will cause the EER score to be lower so a lower portable air conditioner EER may be misleading. It's most readily useful to not permit the EER power status to be your only criteria for selecting an air conditioning system. Do the research o-n what-ever device you are considering for your home and you'll be happier with your purchase.
