Heat pumps need a different kind of smart thermostat — one that manages gradual temperature changes and avoids the deep setbacks that make them run inefficiently. We tested five models, from the Ecobee Premium to the budget Sensi, to find which ones actually optimize heat pump performance.
if you have a heat pump, you've probably noticed that not every smart thermostat plays nice with it. heat pumps work differently from furnaces — they heat gradually, and if you set a big temperature setback (say, dropping 8°F overnight), the system can end up running nonstop all day trying to recover.2 that's not just inefficient — it's hard on the equipment.
the fix is a thermostat that understands heat pump behavior: smart recovery, humidity-based adjustments, and sensors that help balance temperatures without overworking the system. here are the five we recommend.
best for: anyone who wants the most heat-pump-friendly smart thermostat on the market.
the ecobee premium is our top pick for heat pump systems because it actively uses indoor humidity data to adjust temperature set points automatically.1 that matters: heat pumps affect humidity differently than gas furnaces, and the ecobee's Eco+ feature learns how your home responds and tweaks the schedule accordingly.
it also ships with a remote sensor that detects occupancy and temperature, so you're not heating empty rooms. in testing, the ecobee premium kept a 1,500-square-foot, three-level house "more consistently comfortable than any other thermostat" tested.1
key specs: built-in Alexa, Matter-compatible, Apple HomeKit, remote sensor included, works with most heat pumps (including dual-fuel).
best for: google home users who want a thermostat that learns and adapts without manual scheduling.
the 4th-gen nest learning thermostat is "easily the best in google's ecosystem," according to tom's guide.3 its AI learns your habits and builds a schedule automatically, and critically for heat pumps, it uses smart recovery to start ramping up well before your target time — so the system doesn't have to blast heat all at once.
it also integrates seamlessly with google home for whole-home automation. if you're already in that ecosystem, this is the obvious choice.
key specs: AI learning, google home / matter, auto-schedule, smart recovery, works with most heat pumps.
best for: getting the core heat-pump efficiency of the premium model without paying for a built-in speaker.
the ecobee enhanced keeps everything that makes the premium great for heat pumps: the Eco+ smart adjustments, remote sensor support, and humidity-based temperature tuning. what you lose is the built-in alexa speaker and the nicer glass finish. if you already have smart speakers around the house, this is the smarter buy.
key specs: same Eco+ heat-pump optimization, remote sensor compatible, matter / homekit, no built-in speaker.
best for: homes with uneven temperatures or multi-zone setups.
honeywell has been making thermostats for decades, and the t9 brings that reliability into the smart era. its standout feature is the "room priority" mode: place the remote sensor in the room you're actually using, and the thermostat focuses on that room's temperature rather than averaging across the whole house.
for heat pumps, this is useful because you can avoid heating the whole house to the same temperature — let the bedrooms be cooler while you're in the living room, and the heat pump runs less overall.
key specs: room priority sensors, works with most hvac systems including heat pumps, alexa / google assistant, no homekit.
best for: diy installers on a tight budget who still want smart control.
the sensi is the most affordable option here, and it's surprisingly capable for heat pump systems. it supports multi-stage heat pumps and offers flexible scheduling via its app. it doesn't have remote sensors or AI learning, but it does have smart recovery — which is the single most important feature for preventing that nonstop-running problem.2
setup is genuinely easy (the app walks you through wiring), and it works with alexa, google assistant, and apple homekit.
key specs: smart recovery, multi-stage heat pump support, homekit, easy diy install, no remote sensors.

smart recovery is non-negotiable. it's what prevents the thermostat from waiting until 6:00 am to start heating when you've scheduled 6:00 am as your wake-up time. instead, it starts early and ramps up gradually — exactly what a heat pump needs.2
humidity sensing is a close second. heat pumps don't dry the air the way gas furnaces do, so a thermostat that can monitor and adjust based on humidity (like the ecobee models do) helps keep your home comfortable without overworking the system.1
remote sensors matter if your home has uneven temperatures. they let the thermostat know which rooms are occupied and which aren't, so it's not trying to heat the whole house to the same temperature.
