Sustainable and smart technologies expert Matt Ferrell recently highlighted a revolutionary development in the heat pump market in a video on his channel “Undecided with Matt Ferrell.” This new window heat pump design promises to change how renters and homeowners manage their heating and cooling needs, making energy efficiency more accessible to all. Let’s explore what Matt had to say.
Heat Pumps: The Basics
Heat pumps are known for their efficiency, using a small amount of energy to move heat from one place to another. This method allows them to produce more heat energy than the electrical energy they consume. Traditionally, these systems have been out of reach for renters and those unable to retrofit their homes with new installations. But the introduction of window-mounted heat pumps is poised to change that.
The New Window Heat Pumps
Ferrell introduces us to a new type of heat pump that can be easily installed in a window, similar to a window air conditioning unit. This design, known as the “inverse U” or “saddle-style,” is user-friendly, allowing residents to install the unit themselves in about half an hour without the need for professional help. These units also do not require electrical upgrades, as they run off standard 120v AC outlets.
Benefits of Window Heat Pumps
One of the significant advantages of these window heat pumps is their ability to provide both heating and cooling. This dual functionality makes them more versatile than traditional air conditioners, which only cool the air. Additionally, these units have smaller footprints, produce less noise, and include systems to manage condensation, preventing water from dripping down buildings.
Leading the Charge: Midea and Gradient
Two companies, Midea US and Gradient, have risen to the challenge set by the New York City Housing Authority (NYCHA) to improve heating and cooling systems in public housing. Midea will provide 20,000 units, while Gradient will supply 10,000 units for a pilot project. Midea’s Packaged Window Heat Pump (PWHP) has received accolades, including the AHR Expo Innovation Award, for its efficient and user-friendly design.
Efficiency and Performance
Both Midea and Gradient’s heat pumps boast impressive efficiency. Midea’s unit has a Coefficient of Performance (COP) of 2.35 at temperatures as low as 17°F and can operate down to -13°F. Gradient’s heat pump, with a COP of 2.60, functions effectively down to -7°F. These units are designed to handle extreme temperatures, making them suitable for varied climates.
Cost Considerations
Despite their efficiency, the cost of these heat pumps remains a concern. Midea’s unit is priced at $3,000, while Gradient aims to keep theirs around $2,000, though current models sell for $3,800. While these prices are higher than traditional window AC units, the heat pumps’ ability to provide both heating and cooling, along with their efficiency, can justify the investment over time.
Energy Savings and Environmental Impact
Heat pumps are generally eligible for rebates or tax deductions, such as those provided by the Inflation Reduction Act (IRA) in the US. This financial assistance can help mitigate the upfront costs. Moreover, these units use more eco-friendly refrigerants, further reducing their environmental impact compared to older technologies.
Challenges and Considerations
Switching to window heat pumps shifts the heating and cooling costs to the renter’s electricity bill, which could be a deterrent for some. However, the control over temperature and the potential energy savings make them an attractive option. Additionally, concerns about the strain on the electrical grid need to be addressed as more units are deployed.
Too Expensive?
People in the comments shared their thoughts: “I don’t understand why these would be so much more expensive. $3000 for an AC that can run in reverse? Isn’t it just a couple extra valves and a tad more electronics? I could see $1000; but, 3x that amount feels like it’s priced high just to eat federal subsidies.”
Another commenter agreed: “That price is patently ridiculous. It shouldn’t cost 10x more just to have a heat pump be bi-directional lol.”
One person added: “Wait…$3K?!? A 12K BTU minisplit WITH installation is $1500 in Arizona, and it is 20 SHEER. If I were a landlord, I would put a whole bunch of them on the roof where I can centralize the electricity and connections and just run lines down the outside of the building to each apartment, which…is what they do here in three and four storied buildings. I see the potential, and the utility of these units, but…$3K?!?”
A Bright Future for Heat Pumps
The adoption of these window-mounted heat pumps could significantly improve the quality of life for millions of apartment dwellers, not just in the US but globally. While the upfront cost remains a hurdle, the long-term benefits and efficiency gains make them a compelling option for sustainable heating and cooling.
Long-term Energy Savings
What do you think? How can policymakers further incentivize the adoption of energy-efficient technologies like window heat pumps? What measures can be taken to ensure the electrical grid can handle the increased load from widespread use of heat pumps? How can renters balance the initial investment of heat pumps with the long-term energy savings?
