The temperature outside is only barely below freezing, but the electric heaters in our townhouse are having a hard time keeping up (currently 2 degrees below the set temp, and falling). Luckily we bought an air conditioner about a year and a half ago. But as you may have guessed, this is no ordinary air conditioner. It is a DeLonghi Pinguino portable 4-in-1 with heat pump! (may not be the exact same model we have)
Yes, it does keep us cool in the summertime, but I waited years before they finally came up with a reversible unit that would heat as well as cool, and this is the first one I found and it works great! They say:
The AN140HPEWKC Portable Air Conditioner has a maximum cooling capacity of 14,000 BTU/hour and a WHISPER COOL function to provide 50% less sound power for a quieter cool. Perfect for rooms up to 500 square feet, this machine also comes with a dehumidifying and fan function to optimize the balance between temperature and humidity. Additional features of the AN140HPEWKC include a 3810 Watt heat pump, 3 fan speeds, a 24 hour digital timer and thermostat, and an exclusive condensate recirculation system with NO DRIP technology.
We use this unit to keep our entire 1,300 sq ft unit cool in the summer. It is in the living room, but you still feel some cool in the bedroom on the opposite end of the unit, this unit somehow pushes the air nicely down the hallways. It’s Real Feel mode does save energy by balancing the temp and humidity to make both my wife (who is always hot) and I (who am always cold) happy, while also being whisper quiet. Every once in awhile you hear it come on and blow a few puffs, and somehow this keeps us both comfortable. This Real Feel is definitely worth the extra money.
But enough of summer, it’s a distant memory in this cold weather. No, the main reason I purchased this unit is because of the heat pump. They say that this thing puts out 3810 Watts of heat, but using about half that amount of power, but somehow it heats our home to summertime temps, and still cuts the power bill in half!
Why do I say summertime temps? I have a genetic condition called Hemochromatosis, and while it is not a common symptom, it causes me and the other men in my family to feel cold all the time. So, most people who come to visit find the 26C or 80F way too hot, but it is comfortable to me.
Enough about me, back to the heat pump. Until the temperature dropped to freezing, this little unit heated our whole 1,300 sq ft to these summertime temps all by itself. Well, I did have to turn the heat on in the bedroom at night, but it is on the far side of the house and it was only was on for a few minutes to take the chill from the window out.
Now that the temperature has dropped below freezing the heat pumps become less efficient, but I found a workaround for that too. Turning on our electric heat has given this unit a big boost again! Unfortunately the heater is right behind this unit, and every time it came on, this unit got hot, and stopped, but once I diverted the direct heat away from it, the heat pump and electric heat now works in perfect harmony keeping me at summer temps, with very little effort. You see the electric heat warms the room enough that it feeds back into the heat pump and the heat pump basically multiplies that heat like ten fold.
So, while the electric heat may supplement the heat pump more during these freezing temps, the heat pump is still doing the majority of the work.
So, this wouldn’t be a good review if I didn’t include the con’s… They have this NO DRIP technology that vents to the outdoors when in air conditioning mode, but in heat mode there is an undocumented water reserve tank that fills up in our humid environment very quickly. It took me a while to find out what this weird error message “LH” (if I remember correctly) was, there was no documentation on it. But I eventually found that there is a water reserve, with a drain by the power cord. I emptied this I think 3 times the first day, before I put the unit up on a stand, and left the plug open with a bucket underneath. I have to empty it daily in the fall, but it is definitely worth the hassle.
Also, the remote we have is defective, it kept changing all the settings, like from hot to cold. Removing the battery seem to do the trick. However, when in heat mode, the temperature set seems to go up or down. I think it probably uses heat sensitive touch pad, which responds to the units own heat. But it is easy to correct the temp once a day.
I would definitely recommend this unit for all year comfort and energy savings.
