Quilt Fixes Heat Pump Problems: The Breakthrough You Need

Heat pumps are rapidly becoming the go-to solution for efficient home heating and cooling, but traditional systems often struggle to maintain performance in extreme temperatures or across multiple zones. Smart home startup Quilt is changing that with its innovative three-zone heat pump, promising consistent efficiency even under demanding conditions. This breakthrough, fueled by a recent $20 million Series B funding round, isn't just about a new product; it's about a data-driven approach to HVAC that’s reshaping the industry. This article dives deep into Quilt’s technology, its advantages, and what it means for the future of home comfort.

The Three-Zone Revolution: Simplicity and Efficiency

Quilt’s new three-zone unit simplifies large-scale installations by allowing a single outdoor unit to power three indoor heads. This minimizes the outdoor footprint, reducing visual clutter and installation complexity. This is a significant advantage for homeowners and installers alike, offering a more streamlined and cost-effective solution compared to traditional multi-zone systems. The ability to manage multiple zones independently also contributes to energy savings, as heating or cooling can be directed only where it’s needed.

Data-Driven Innovation: The Quilt Advantage

What truly sets Quilt apart isn’t just the hardware, but the software and the data behind it. From the outset, Quilt has prioritized data collection from its heat pumps. Unlike conventional systems, Quilt units are equipped with a wealth of sensors and are constantly connected to the internet. This allows the company to gather real-world performance data, providing invaluable insights into how the systems operate in diverse climates and conditions.

Over-the-Air Updates: Continuous Improvement

This commitment to data has already yielded tangible results. In September, Quilt pushed out an over-the-air update that unlocked an additional 20% capacity in existing heat pumps. This update allowed users to better handle heat waves and cold snaps, enhancing comfort without requiring any hardware modifications. This demonstrates Quilt’s ability to continuously improve its products and adapt to changing user needs, a capability rarely seen in the HVAC industry.

Solving the Low-Speed Challenge

Multi-zone heat pumps excel when operating at variable speeds – adjusting the compressor’s output to match the heating or cooling demand. However, traditional compressors struggle to maintain stability at very low speeds. Matthew Knoll, co-founder and CTO at Quilt, illustrates this with an analogy: maintaining a constant 70 mph is easier than a steady 11 mph. This instability forces most systems to stop the compressor at a certain point, sacrificing efficiency and comfort.

Quilt tackled this challenge head-on by leveraging the data collected from its installed units. Instead of relying on limited lab testing, Quilt analyzed real-world performance across a thousand homes and businesses. This allowed them to identify and address the limitations of traditional compressor control algorithms.

Real-World Testing vs. Lab Simulations

“The way most systems are developed, they’re tested in a lab under a couple scenarios because testing’s expensive. And you end up with kind of an average product,” explains Knoll. “We have a thousand units out there in many different climates, and if we see something, we can look at it across a bunch of different units to understand if there’s room to optimize or if we’re seeing a problem in a corner case.” This data-driven approach is a core differentiator for Quilt, allowing them to create a product that performs optimally in a wider range of conditions.

Engineering for Extreme Performance

Beyond software optimization, Quilt also made key hardware improvements. The company utilizes a larger copper coil than many competitors, enabling the use of a smaller, more efficient compressor. Combined with other design tweaks, this allows Quilt to deliver nearly 90% of its rated capacity (27,000 BTUs) at -13˚ F (-25˚ C) without compromising low-demand performance or efficiency. Quilt confidently claims its three-zone mini-split is the most efficient on the market.

Precise Zone Control and Minimal Heat Loss

Each indoor head can be individually controlled, delivering as little as 2,210 BTUs of heat or 1,570 BTUs of cooling. Even when heating or cooling isn’t required, refrigerant continues to circulate through the lines, a standard feature of heat pumps. However, thanks to the outdoor unit’s low-speed performance, it only releases around 300 BTUs of heat in heating mode – roughly the amount of heat generated by an average adult. This minimizes energy waste and ensures consistent comfort.

The Future of Quilt: Expanding the Horizon

With the success of the three-zone unit and the momentum from its Series B funding, Quilt is poised for further expansion. Knoll remains tight-lipped about specific future plans, stating only that Quilt “wants to be able to have a solution for all homes.” This suggests a broader product roadmap aimed at addressing the diverse heating and cooling needs of homeowners across various climates and property types.
