Hisense 6517277

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Hisense 6517277.They may be the same unit sold under several brands, or different products that test the same: the DOE data has no dimensions or noise figures, so check those with the maker. Ratings within about 2% in capacity and 0.3 in CEER are treated as the same; a model whose own rating differs a little shows it in brackets.

Compared with every DOE-certified portable unit in the same size class (SACC). Each model number counts once. Yearly cost at 750 hours and 18.0¢/kWh.

This unit at each city's cooling hours and state electricity price, against a window unit that cools as much.

What size room does the Hisense 6517277 cool?

12,000 BTU of real cooling (SACC) suits about 450 to 550 sq ft with normal sun and two people (about 405-495 sq ft if very sunny), by the ENERGY STAR floor-area table. Size by SACC, not the larger BTU on the box.

How many watts does the Hisense 6517277 use, and what does it cost to run?

About 1000 watts at full power (12,000 BTU/h divided by its CEER of 12.0), roughly 8.7 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $135, which is $8 more than the typical certified 12,000 BTU or more portable unit ($127). Its CEER beats 21% of the 147 certified models in its size class.

Why does the Hisense 6517277 have two hoses?

One hose brings outdoor air in to cool the condenser, the other sends the heat out, so no cooled room air is wasted. 99% of the certified 12,000 BTU or more models have two hoses, and at 12.0 CEER this one is below their 12.8 median.

How does the Hisense 6517277 handle the water it removes?

It drains by gravity: you run a hose from the unit to a floor drain, a sink or a bucket that stays lower than the unit. Do not coil the hose or lift it above the outlet.

How does the Hisense 6517277 heat?

It has a heating function, but the DOE data records only that it exists, not whether it is a heat pump or an electric element. Ask the maker: a heat pump gives more heat per kWh than a resistance element, which costs the same as any space heater. 33 of the 147 certified 12,000 BTU or more models can heat.

Is the Hisense 6517277 as efficient as a window air conditioner?

No. The 40 ENERGY STAR certified window units that cool about as much (within 15% of 12,000 BTU) have a median CEER of 15.0, against 12.0 here, and the best reach 16.8. At 750 hours a year a window unit with that median would cost about $108, $27 less than this one. ENERGY STAR window units are the more efficient part of the window market, so the gap to an average window unit is smaller. A portable unit makes sense when a window unit will not fit or is not allowed.
