Walk N Talk AHR Expo 2024: Unpacking Midea's Revolutionary Window Heat Pump

Michael had the pleasure to speak with David from MIDEA at the 2024 AHR Expo exploring a groundbreaking innovation in home heating and cooling: the Midea PWHP, a window-mounted cold climate air source heat pump.
The Midea PWHP is designed for easy installation in standard windows using a 120V/15A circuit, thanks to its innovative saddle design and adjustable center section. This unique design allows for installation in windows with lower opening heights and reduces the footprint by 50%, a first in the industry with its integrated inverter compressor.
This cutting-edge device is not only DIY-friendly but also remarkably efficient, boasting 9,000 BTU/hr of heating and cooling power with a top CEER of 16.0. It stands out for its energy efficiency, achieving a 2.35 COP at 17°F, SEER2 of up to 21.8, and HSPF2 of 11.6, all while functioning effectively down to -13°F without auxiliary heat.
Beyond its technical prowess, the Midea PWHP is a key player in the Clean Heat For All challenge. This initiative, led by the NYPA, NYCHA, and NYSERDA, aims to transition NYCHA buildings from steam heating to more efficient air source heat pump heating. Midea's PWHP aligns perfectly with this goal, supporting NYCHA's mission to reduce greenhouse gas emissions by 80% by 2050 and offering a viable, efficient heating solution for numerous municipalities and companies across the U.S.

Very informative interview. I live in a very small brick home that is only 646 square feet and I'm looking for something like this in the future when the prices come down. One of their competitor's Gradient is selling their unit for about $5000 (US dollars) when they originally estimated it would be about $1999 and that's too much for me when I can just buy a $300 window air conditioner to keep my small home comfortable.

Oh *heck* yes. This looks smashing.

[@Chris-ut6eq]

Availability in the USA? MSRP?

[@Egleu1]

Do we know when this will be available for consumers to buy?

[@blazetownsend8785]

Same question here.

This is awesome! I have a large house and I would have to put a mini split in so many rooms it really didn't save me any money and it wouldn't save electricity but I think this might work! But I don't like to buy things when they first come out I want to wait until they get the glitches worked out of them😅 Also my concern is will it keep your house warm when it's 11° outside? That's my concern for heat pumps?😢 Thanks for posting this I'm still on the fence and my Lennox is on its last leg but I think I'm going to wait and see how this works... I'm really excited that especially with the size and if it really saves US money 😁🙏🇺🇲

I have 2 midea u shape air units, so far I have been impressed. There not a year old yet so we will see how long they last and if there is a problem how easy it is to service them. That unit would be great in Florida because you could run it on a Generator in a emergency. I wonder what Midea is doing about having qualified techs to service them around the country. So many people I know installed mini splits but can't find anyone to service or repair them.

[@Chris-ut6eq]

availability is key. I can't even find this on their website.

I saw a lot of cool innovations, like the handles, it's fold able for install etc... But both the ad I saw that lead me here, and the video both, make it sound like this is the first time anyone has made a window heat pump.That's not true, I have used window heatpumps from several different manufacturers. Ranging from 8k btu up to 28k btu. When we bought our current trailer, we decided to turn down the central unit, so we could keep using the window heat pump units. But, I will definitely check this out, I do need to add one.

You didn't ask the really important questions of when it's going to be available and what's the target price range. Touting the technology isn't useful if nobody can buy it. My landlord really wants to put in heat pumps because my idiot neighbors like to run their thermostats at 78º and he's paying for the natural gas for the building's boiler. He's thinking of putting in mini-splits, but they're not cheap and neither is the installation. I told him he should wait for these, but he's getting impatient. He wants to do it this year, 2025 at the absolute furthest out.

[@mikemotorbike4283]

landlords learned this many years ago: set real temp to 69-72 degrees F. Put in fake thermostat enclosed within locked clear plastic thermostat cover product. Tenant will sneak a paperclip in there and feel oh so clever.

Now make one for SLIDE windows! Why is it so much bigger and less powerful than the unit Midea sells on Amazon for $500? (It is the size of a small air conditioner and is 12000 BTUs, but only heats down to 41degrees - no defrost cycle)

[@newporttom]

Bingo !!! I have a sunroom with slide windows. I'm wondering whether I can convert one window to a vertical.

[@yamspaine]

Slide windows would be great, it should be doable... It might take a big box.
