HOW TO MAKE A HEAT PUMP MORE EFFICIENT IN WINTER

September 19, 2023

Heat pumps are known for providing efficient home heating and cooling, but their performance can vary based on their use. Unlike traditional furnaces, heat pumps require specific strategies to maintain efficiency, especially during winter. Understanding how to make a heat pump more efficient in winter can reduce energy consumption, lower utility costs, and keep your home comfortable all season.

1. ADJUST THE THERMOSTAT AND KEEP TEMPS CONSISTENT

Heat pumps are designed to provide even, consistent heat at a slower rate than traditional furnaces. Frequent adjustments, such as raising the temperature more than two to three degrees, can engage costly auxiliary heating like electric heat strips, which consume significantly more energy. For optimal efficiency, set your thermostat to around 68°F while you're home and awake, and only lower it by a degree or two at night or when away. This approach balances comfort and energy savings, reducing overall heating costs.

2. UPGRADE YOUR THERMOSTAT

A thermostat designed for heat pumps is essential for maximizing efficiency. These thermostats help you control when the auxiliary heat activates, reducing reliance on costly backup heating. They also optimize your heat pump by starting it earlier to reach your desired temperature without overworking the system. For added convenience, choose a thermostat model that integrates with components like a humidifier, allowing seamless control of your home’s comfort systems and maximizing energy savings.

3. KNOW WHEN TO USE THE TIMER

Using the timer feature on your heat pump’s thermostat can help manage energy use, but it’s important to know when it’s effective and when it’s not. Here’s a quick guide:

When to Use the Timer:

To maintain a consistent temperature during specific times, such as when you're at work or sleeping.
To gradually warm your home before you wake up or return, avoiding sudden temperature spikes.

When Not to Use the Timer:

Avoid frequent or drastic temperature changes, as they can activate auxiliary heating and increase costs.
Do not turn the system off entirely during winter; restarting it can use more energy to regain warmth.

A properly used timer ensures your heat pump operates efficiently while keeping your home comfortable.

4. OPT FOR A LOWER TEMPERATURE SETTING

Setting your heat pump to a lower temperature can significantly improve efficiency during winter. Aim for a thermostat setting around 68°F while you’re home and awake. This temperature strikes a balance between comfort and energy savings. Avoid drastic changes or setting it too low, as your system may need more energy to reheat your home. For times when you’re away or sleeping, lower the temperature slightly but keep it within a few degrees to prevent auxiliary heat from activating.

5. AVOID RUNNING IT ALL DAY UNNECESSARILY

Heat pumps operate most efficiently when outdoor temperatures are above 25–30°F. Below this range, their efficiency drops significantly, and they may rely on auxiliary heating, which is more expensive to run. To save energy, avoid running your heat pump all day during extreme cold. Instead, set it to a lower, consistent temperature and let it maintain that level. This approach is key to how to make a heat pump more efficient without driving up costs.

6. USE A HIGHER FAN SPEED

Using a higher fan speed on your heat pump can improve efficiency by circulating warm air more effectively throughout your home. This setting works best in milder winter conditions, as it helps distribute heat evenly without overburdening the system. However, a lower fan speed may prevent drafts and ensure consistent warmth during extremely cold days. Adjusting fan speed strategically is another smart approach to how to make a heat pump more efficient in winter.

7. DIRECT THE AIRFLOW

Properly directing the airflow from your heat pump can significantly affect heating efficiency. Ensure vents and registers are clear of obstructions like furniture or curtains to allow warm air to circulate freely. Aim for the airflow to go downward in rooms with adjustable vents to help distribute heat evenly at the floor level. Small steps to optimize airflow can reduce strain on your heat pump and create a more comfortable living space.

8. REGULARLY CHANGE THE FILTER

A clean filter is essential for your heat pump to run efficiently, especially in winter. Dirty filters restrict airflow, forcing the system to work harder and reducing efficiency. Regularly changing the filter improves energy savings and enhances indoor air quality by removing dust and allergens. For comprehensive care, schedule a professional maintenance service with Columbus Worthington Air by calling 614-405-7819 and ensure your heat pump performs at its best.

9. ENSURE PROPER HOME INSULATION

Good insulation is vital for maintaining heat pump efficiency in winter. Poorly insulated walls, windows, or doors allow warm air to escape, forcing your system to work harder and use more energy. Check for drafts and seal gaps with weatherstripping or caulking. Consider upgrading the attic or wall insulation if needed. A well-insulated home keeps the warmth inside, reduces energy waste, and ensures your heat pump operates effectively, even during the coldest months.

10. AVOID AUTO MODE

Using the "Auto" mode on your heat pump can reduce efficiency during winter. This setting automatically switches between heating and cooling, which can lead to unnecessary energy use and frequent cycling. Instead, set your heat pump to "Heat" mode to ensure consistent performance and avoid activating cooling functions. Small adjustments like this are a smart way to learn how to make a heat pump more efficient in winter.

11. DON’T OVERUSE DEFROST MODE

Defrost mode is essential for clearing ice buildup on your heat pump’s outdoor unit, but overusing it can decrease efficiency. While the system handles defrosting automatically, excessive reliance on this mode may signal an underlying issue, such as poor airflow or improper installation. To avoid unnecessary energy use, keep the outdoor unit clear of snow and debris, ensuring it operates smoothly. Proper maintenance helps your heat pump stay efficient without overusing defrost mode.
