Quilt's New Three-Zone Heat Pump Hits 90% Efficiency at -13°F

What if your heater got smarter and more powerful while you slept? Smart home startup Quilt just unveiled a new three-zone heat pump that promises exactly that. Fresh off a $20 million Series B funding round, the company is leveraging massive real-world data to outperform traditional HVAC giants in extreme conditions.

Data-Driven Innovation: The Quilt Three-Zone Heat Pump Advantage

According to TechCrunch, Quilt isn't just building hardware; they're building a data engine. While incumbents rely on limited lab testing, Quilt analyzes data from over 1,000 installed units across diverse climates. This approach allowed them to ship an over-the-air (OTA) update last September that unlocked an extra 20% capacity for existing users—free of charge.

The real challenge in HVAC is low-speed stability. CTO Matthew Knoll compares it to driving: maintaining a steady 11 mph is much harder than cruising at 70 mph. Most systems simply shut off when demand is low, sacrificing comfort. Quilt's sensors and algorithms allow their compressors to run smoothly at ultra-low speeds, keeping homes comfortable without wasting energy.

Unrivaled Performance in Extreme Cold

The hardware is just as impressive. By pairing a larger copper coil with a smaller compressor, Quilt can deliver nearly 90% of its 27,000 BTU rated capacity even when temperatures plunge to -13°F (-25°C). Each indoor head is individually controlled, and at its lowest setting, it releases only about 300 BTUs of heat—roughly the same as a grown adult.
