    In fact, the maximum coverage is just 350 square feet. It is best suited for an ice fishing hut or single room rather than a large space. The good news is that the Pioneer is very lightweight, quiet, and compact.

    Buyer’s Guide: How to Select the Best Heat Pumps For Cold Weather

    Different Types of Heat Pumps

    There are three types of heat pumps available on the market: air-source, split-ductless, and geothermal. Knowing the difference between these three types is crucial for determining which heat pump is right for you. The most common type of heat pump is an air-source heat pump. HVAC professionals often install the pumps, which include an outdoor unit and an indoor air handler.

    The second most common type of heat pump is the split-ductless variety. You can install them on your own because they do not require ducts to be in place to function. These pumps often only heat one room or a small space.

    Lastly, there are geothermal heat pumps. They use buried pipes to maintain constant ambient heat. Geothermal heat pumps are the least common because they require a lot of room and money. A typical geothermal system can cost up to $30,000 to install.

    Always Check The Temperature Ratings

    Heat pumps all have an official temperature rating. The numbers dictate which temperatures the system can run at while outside. Even if the temperature numbers are not readily available, they should be buried in the technical specifications. Always double-check the allowable temperature range before buying.

    We tried to put as many cold weather pumps on this list as possible, but check the temperature range if you are looking at heat pumps on your own. You will be surprised to find that some of the units on the market have ranges that hardly dip below freezing. If you buy a system with a 15º F low and have to live through a sub-zero cold snap for a week, you will be very cold.

    What Is SEER?

    SEER stands for Seasonal Energy Efficiency Ratio. It is a metric the federal government uses to regulate the efficiency of air sources and split-ductless air systems. The higher the SEER rating, the more efficient the heat pump. A more efficient heat expends less energy on heating and cooling the room. The minimum federal guideline for heat pump SEER ratings is 14.

    Another energy efficiency rating you might see while shopping for heat pumps is the Heating Seasonal Performance Factor (HSPF). This rating is less commonly used but applies to heat pumps. A good HSPF rating is more important for cold-weather heat pumps than SEER, but the HSPF rating is harder to find than SEER.

    Consider The Noise

    Heat pumps can be noisy. Some product descriptions provide an average noise level in decibels, but many don’t. Some heat pumps are known to be extremely noisy. Since many of these products require an indoor wall-mounted air handler, the noise factor can a significant concern.

    You do not want to install a brand-new heat pump system next to your bed only to find out that the noise will keep you up all night. Heat pumps are usually noisey, but some come with low-noise modes for bedrooms.

    Know Your Space

    Most of the heat pumps that you can buy and install are split-ductless heat pumps. They are often made to heat one room and offer varying coverage. Before taking the plunge on a heat pump, it is best to know the space you will be installing it in. Is the room drafty? How large is the space? How hot/cold does it get normally? These are essential questions to ask before purchasing a heat pump.

    One of the most common complaints online is from people who installed undersized heat pumps and complained that they do not heat and cool appropriately. It is frustrating to find a heat pump with great reviews only to realize it is made to heat 350 SF when you need to heat 700 SF. Even if the BTU numbers look good, if the air handler is not equipped to pump air into a larger space, it won’t heat efficiently.

    Know your space before you buy. It could save you a lot of time, money, and effort.
