   I needed an air conditioner for my top floor, 15×20 foot master bedroom with windows that open side-to-side. This unit cools the room very quickly and keeps the room cool at the temperature I set. The remote is great and works across the room. I have not tried the heating unit nor the dehumidifier. The unit is rather loud on high and during rapid cooling, but it’s no louder than a window unit on high. The sleep mode is decently quit, and the compressor kicking on and off was not a complete distraction and didn’t wake me up during the night. My electric bill only increased ~$1 a day of continued air conditioning use during the summer for the room size I have. I’m so glad I have a 65 degree bedroom on 100+ degree days!!

   This review is for the ‎OX-10KH Wiytamo portable heat pump model.

   TL;DR: I bought this product primarily for its heat pump functionality. If you do the same, you’re almost certainly going to be disappointed. It’s not a very well designed or efficient product. The heat pump performs poorly at best. After buying and using this product, I really have to wonder how many of the reviews here are real. I encourage you to read on, if you have the time. You get what you pay for.

   At first startup, after letting it rest for the required twenty four hours, it took at least ten minutes before the unit showed any sign of cooling. I began to wonder if it had actually survived shipping, or if it had been charged with refrigerant at the factory. I’m still suspicious as to whether or not it was charged correctly with refrigerant for reasons I’ll get into later.

   The first problem is with the airflow design. This model uses a single tube to exhaust air from which heat or cold has been extracted. Unlike some models where the tube contains two separate pathways for supply and return air, the ‎OX-10KH takes air from the room you are heating or cooling, pulls it over a coil to extract thermal energy and then throws it outside. This reduces operating efficiency in both heating and cooling modes, but it’s especially bad in the heating mode, as the unit is working against itself. The air that it heats up is having the heat stripped back out of it as it flows into the lower air intake and coil. All that’s really being added is whatever heat the compressor motor imparts to the refrigerant, making this a very inefficient sort of “resistance heater”. Efficiency in cooling mode will suffer for the same reason, though I see it as slightly less of a problem there.

   Other questionable design decisions include the size of the included window venting adapter (there’s no reason it should be about two feet long at its smallest size) and the water pans. Many windows just aren’t that big, especially in an older home. At least you could cut it down to size for a smaller window. The water pans are also poorly designed. It’s hard to tell from the fractured English in the manual, but it appears that the upper water drain (used in cooling mode) has to be connected to a suitable drain or container when running in cooling mode. The lower drain (for heat pump mode) is very close to the floor and will be awkward to use. The manual suggests putting the unit on a pedestal to make draining it easier and I’d agree.

   The presence of a small drain pan for the lower drain is implied by the manual. What’s less clear is whether or not the unit will shut off when this fills up, or if you will have to watch to make sure it does not. I don’t believe the unit will shut off when the upper drain has filled with water.

   Finally, there is the performance in heating mode. This is seriously lacking. In a 40 degree Fahrenheit room, the Wiytamo OX-10KH could only manage to put out air heated to around 75-78 degrees Fahrenheit. Any heat pump of reasonable quality will output far warmer air than this. I would have expected an output air temperature of at least 100 degrees. If you look at a temperature/pressure chart for Refrigerant 32 (the refrigerant used in this model), it’s quite capable of maintaining sufficient pressure even at low temperatures to extract heat energy from what most of us would consider “cold” air. (There is still considerable heat energy in air as cold as 0 degrees Fahrenheit.) You just won’t get that kind of performance from this model. At 23 degrees Fahrenheit ambient, the Wiytamo was unable to extract any heat from the surrounding air. At least it will try, although it would not let me select the higher fan speed in either the 40 or 23 degree conditions.

   I have yet to try the cooling mode and cannot comment on its performance at this time. If this product is still on the market in the near future, I will update this review accordingly.

   There is still a question in my mind whether the example of this product I received is properly charged with the right amount of refrigerant, or if the compressor is pumping properly. I seriously doubt there are refrigerant service ports inside this product. As an HVAC/R technician, I would love to put a set of manifold gauges on it and see if it really was charged properly. (Don’t tinker with refrigerant of any kind unless you know what you are doing and have the proper handling licenses.)

   Ordinarily, I would return this product. Unfortunately, I’d have to bear the cost of doing so. Combine that with the time it would take to package everything all back up, along with the considerable expense of returning such a large (~40 inches tall) and heavy (~45 pound) item from almost clear across the United States and it just wouldn’t be worthwhile. It might even cost more to do so than the initial purchase price.

   This portable AC is exactly what I was looking for. It cool extremely well. The heating isn’t great if you’re expecting it to super heat your place. There was an issue with my original AC and I contacted their customer service email and they sent me a new one. The process is very easy. So while the original AC I purchased didn’t last that long, if all it takes is a couple email to costumer service to get a new one sent out to me at no cost to me, I’m totally fine with that.

   The media could not be loaded.

   So far the product is working great. Don’t have any complaints will update if there is anything. To assemble the product it wasn’t hard the user guide was super easy to read and super straightforward, took about five minutes to set up and turn on. It took a while for the cold air to start but after about 1-2 minutes it started to really make my room cold.

   Started to make a rattling noise it, the noise comes and goes but everything else is still good
