Heat Pumps vs. Boilers: Why New Research Shows Heat Pumps Are Up to 3x More Efficient
Heat Pumps vs. Boilers: The Efficiency Reality
A recent multi-year study conducted by France’s Environment and Energy Management Agency (ADEME) tracked real-world heat pump performance in single-family homes. These weren’t lab tests—they were systems installed to replace existing gas and oil boilers and monitored through full heating seasons.
The results were clear:
Air-to-water heat pumps averaged nearly 3x efficiency
Geothermal (water-to-water) systems exceeded 4x efficiency
Even air-to-air systems consistently outperformed combustion-based heating
Efficiency was measured using the Seasonal Coefficient of Performance (SCOP). A SCOP of 3 means the system produces three units of heat for every one unit of electricity consumed. By comparison, even high-efficiency boilers max out well below that threshold.
In plain terms: heat pumps don’t “create” heat—they move it, which is why they’re fundamentally more efficient than burning fuel.
Why Europe Is Moving Faster—and Why the U.S. Is Catching Up
France, like much of Europe, has aggressive carbon-reduction targets. Buildings are a major focus, and electrified heating is one of the fastest ways to cut emissions while reducing long-term energy costs.
But this isn’t just a European story anymore.
In the U.S.:
Heat pump shipments now outpace gas and oil furnaces
Roughly one-third of American homes already use a heat pump
Nearly half of new and replacement heating systems installed by contractors are heat pumps
Electricity has become the primary heating source for over 40% of U.S. households
Even in multifamily buildings—long considered difficult to decarbonize—new heat pump technologies are proving both practical and cost-effective.
The market has already shifted. The conversation is just catching up.

What’s Still Holding Heat Pumps Back?
Despite the data, adoption hasn’t been universal. Why?
Outdated perceptions
Cold-climate performance and noise concerns linger, even though modern systems are designed specifically to address both.Improper design and installation
Studies show many underperforming systems suffer from poor sizing or setup—not technology limitations. Heat pumps demand precision, not shortcuts.Desire for choice
Many homeowners still want options. In some cases, gas may make sense. In others, a heat pump is clearly the better solution. The key is matching the system to the building and the homeowner’s goals.
At Denair HVAC, we see this daily: the technology works best when it’s designed correctly, installed properly, and explained clearly.

The Bigger Takeaway
This isn’t about banning boilers or forcing one solution on every home. It’s about recognizing a shift that’s already underway.
Heat pumps aren’t experimental. They’re proven, efficient, and increasingly mainstream. And when designed by experienced professionals, they deliver what homeowners care about most: comfort, reliability, and long-term savings.
