Finding the best temperature for heat pump in winter is one of the most common questions homeowners across Vancouver and the Lower Mainland ask once colder weather sets in. Heat pumps work differently than furnaces, and how you set your thermostat has a direct impact on comfort, energy use, and long term system performance.
If you have recently installed a heat pump or are considering one, understanding the best temperature for heat pump in winter will help you stay warm while keeping operating costs under control. This guide is written specifically for Lower Mainland homes and reflects how heat pumps perform in our coastal climate.
Now let’s break down what temperature actually works best and why.

To understand the best temperature for heat pump in winter, it helps to know how the system operates. Unlike gas furnaces that generate heat quickly by burning fuel, heat pumps move heat gradually from one place to another.
Even in cold weather, there is usable heat energy in the outdoor air. A heat pump extracts that heat and transfers it inside. This process is very efficient, but it works best when temperatures are kept steady rather than frequently adjusted.
Heat pumps are designed to maintain comfort, not chase rapid temperature changes. That difference is the reason winter thermostat habits often need to change for homeowners switching from furnaces to heat pumps.
For most Lower Mainland homes, the best temperature for heat pump in winter falls between 20°C and 22°C during the day. This range balances comfort and efficiency while allowing the system to run steadily without overworking.
Some homes may feel comfortable closer to 19°C, while others prefer 22°C or slightly higher. The key is consistency. Heat pumps perform best when they are allowed to maintain a set temperature rather than being adjusted multiple times throughout the day.
At night, many homeowners lower the temperature slightly. With heat pumps, a small reduction of 1°C to 2°C is usually enough. Large setbacks can cause the system to rely on backup heating, which is less efficient.
One of the most important principles behind the best temperature for heat pump in winter is steady operation. Heat pumps are most efficient when maintaining temperature rather than recovering from large drops.
If you lower your thermostat too much overnight or while away, the system may activate supplemental heat to catch up. That backup heat uses more energy and increases costs.
For this reason, many experts recommend choosing a comfortable temperature and leaving it there as much as possible. If adjustments are needed, make them small and gradual.
No two homes are exactly alike, and several factors influence what feels comfortable.
Insulation quality plays a major role. Well insulated homes retain heat better and often feel comfortable at lower thermostat settings. Drafts, older windows, or poor air sealing can make a home feel cooler even at higher temperatures.
Layout also matters. Open concept homes distribute heat more evenly, while multi level homes may experience temperature differences between floors.
Because of these variables, the best temperature for heat pump in winter should be viewed as a range rather than a fixed number.
Ductless and central heat pumps behave slightly differently in winter.
With ductless systems, keeping indoor units running continuously is key. Turning units off in unused rooms can cause uneven temperatures and increase overall workload on the system.
For central heat pumps, airflow and duct condition are critical. Leaky or poorly insulated ducts can reduce comfort and efficiency, making it harder to maintain the best temperature for heat pump in winter.

Some heat pump systems include backup heating, such as electric resistance heat. Backup heat is designed for extreme cold or unusual demand, not daily operation.
To maintain the best temperature for heat pump in winter, avoid large thermostat changes that trigger backup heat unnecessarily. Keeping your primary heat pump thermostat set consistently allows the system to handle most winter conditions efficiently.
If you notice your backup heat running frequently, it may be a sign of thermostat settings, airflow issues, or a system that needs service.
Humidity affects how warm a home feels. Dry winter air can make indoor temperatures feel cooler than they actually are.
By maintaining proper humidity, you may find that the best temperature for heat pump in winter feels lower than expected. Many homeowners feel comfortable at 20°C when humidity levels are balanced.
Simple solutions like portable humidifiers or whole home systems can improve comfort without increasing heating demand.
Regular maintenance helps your system deliver consistent comfort at your chosen temperature. Dirty filters, blocked outdoor units, or neglected inspections can reduce efficiency and airflow.
Annual servicing ensures your heat pump can maintain the best temperature for heat pump in winter without strain. Maintenance also extends system lifespan and helps prevent mid winter issues.

Following these guidelines alongside professional advice helps ensure your heat pump performs as intended throughout winter.
While consistency is important, small seasonal adjustments may still be necessary. During cold snaps, you may raise your thermostat by 1°C to maintain comfort. As outdoor temperatures moderate, you can return to your usual setting.
The goal is to avoid dramatic changes. The best temperature for heat pump in winter supports steady operation rather than rapid recovery.
Choosing the best temperature for heat pump in winter is not just about today’s comfort. It impacts long term energy costs, system wear, and overall satisfaction with your heating system.
If you are unsure whether your heat pump is operating as efficiently as it should, or if you are struggling to find a comfortable setting, professional guidance can make a noticeable difference.

What is the best temperature for heat pump in winter during the day?
For most homes, the best temperature for heat pump in winter during the day is between 20°C and 22°C, depending on comfort preferences and insulation.
Is it okay to lower the thermostat at night with a heat pump?
Small reductions of 1°C to 2°C are fine. Large setbacks can reduce efficiency and trigger backup heat.
Why does my heat pump feel cooler than a furnace at the same temperature?
Heat pumps deliver heat gradually, so the air may feel less hot even though the room reaches the set temperature.
Does humidity affect the best temperature for heat pump in winter?
Yes. Proper humidity can make lower temperatures feel warmer and more comfortable.
How often should a heat pump be serviced in winter?
Annual maintenance is recommended to ensure the system can maintain the best temperature for heat pump in winter efficiently.
