Best Heat Pump Buying Guide

Size (Capacity)
A heat pump that’s too small for your needs will struggle to keep your home comfortable. On the other hand, an oversized unit will cost more, and if it isn’t a variable-speed model, it will cycle on and off more often than it should. This decreases efficiency, stresses components, and leaves your home less comfortable.

A heat pump’s cooling capacity is measured in British thermal units per hour (Btu/hr.). Btu/hr. can also be expressed in “tons,” with 1 ton equaling 12,000 Btu/hr. To ensure that your heat pump is sized correctly, make sure your contractor does a load calculation based on a recognized method, such as the Air Conditioning Contractors of America (ACCA) Manual J. The calculations should be made after any air-sealing or insulation upgrades are made to your home and should be done whether you’re replacing a unit or installing a new system.

One nuance to consider: If you’re planning on keeping a backup heating system alongside your heat pump, you could consider getting an undersized heat pump. A contractor can help you figure out whether this makes sense in your home.

Note that heat pumps need far less capacity to heat a space than a furnace or boiler would because they’re much more energy-efficient. For example, if your home needed a 100,000-Btu/hr. furnace, it may need only a 36,000-Btu/hr. heat pump.

Compressor Type
The compressor is the heart of a heat pump—it’s the part that actually pumps the heat. Basic heat pumps have a single-speed compressor. It’s either on or off. This system works well enough, but the temperature and relative humidity in your home will swing up and down with the cycles. Some compressors have two speeds, which mitigates the swings, but they’re still present.

The gold standard is a variable-speed compressor. It’s designed to run almost constantly, adjusting itself over time to deliver only as much heating or cooling as it takes to keep your home comfortable. It’s also much better at keeping relative humidity under control than single-speed models are.

Variable-speed compressors not only keep your home more comfortable but also are more energy-efficient. It may seem counterintuitive, but it takes much less energy to move a tiny bit of heat all the time than to move a lot of heat quickly.

Efficiency
Some heat pumps use less energy than others to deliver the same level of comfort. In cooling mode, efficiency is commonly expressed as the seasonal energy-efficiency rating, or SEER. The higher the SEER, the greater the efficiency. In heating mode, the measurement used is heating seasonal performance factor, or HSPF. Again, the higher the number, the more energy-efficient the unit.

Heat pumps with higher SEER and HSPF ratings tend to cost more, but they’ll often pay for themselves over time through lower energy costs, and they may be eligible for better tax incentives or rebates than less efficient models. Heat pumps with higher SEER ratings also tend to have higher HSPF ratings, though there’s no direct relationship between the two. If you live in a warm climate, pay closer attention to the SEER. In cold climates, look for a higher HSPF.

The minimum SEER allowed for a new split system heat pump in the U.S. today is 13, and 14 in the southern half of the country. The minimum HSPF is 8.2. Systems that meet Energy Star guidelines for efficiency have a minimum SEER of 15. The minimum federal standards are all set to increase in early to a SEER of no less than 14 in northern regions, and 15 in southern regions, as well as a minimum HSPF of 8.8. The most efficient models have a SEER of 33.1 or an HSPF of 14.

Climate Performance
If you live in a region with cold winters, you’ll need to either pick a heat pump that’s rated to work well in the lowest temperatures that your region regularly experiences or have a secondary heating system to back up your heat pump.

All air-source heat pumps struggle to perform as temperatures drop; the space they can effectively heat shrinks, and they don’t work as efficiently. The threshold for poor performance varies from model to model: Some heat pumps falter at 25° F, others at 17° F or lower.

Models marketed as cold-climate heat pumps can work to their full potential all the way down to 5° F and may deliver some heat even down to -20° F or lower. The best course is to work with a qualified local contractor who knows what kind of equipment works well in your area.

If you live in an area where the temperature rarely or never drops below freezing (32° F), a basic heat pump can handle the bulk of your heating and cooling needs. You can keep a simple electrical-resistance backup system (sometimes built into the heat pump itself) for unusual cold snaps.

Noise
Manufacturers publish the noise levels for their products in the user manual and often on their websites. They tend to include noise estimates across a variety of outdoor temperatures and fan speeds, measured in decibels. A lower rating is better, especially if the heat pump will be installed near a bedroom window.

Reliability
According to our member survey, reliability is by far the top predictor of an owner’s overall satisfaction with a heat pump. Consumer Reports members can see the predicted reliability and owner satisfaction ratings for 24 brands of heat pumps, based on data that CR members have shared about almost 13,500 heat pumps they’ve bought new and installed in their own homes between and . Those findings are summarized in our guide to the Most and Least Reliable Heat Pumps.

Heat Pumps – Analysis

Several policies to support the heat pump market are currently being developed, prompted by record-high energy prices and the anticipation of upcoming winter challenges following the Russian invasion of Ukraine. The REPowerEU plans to double the deployment rate of hydronic heat pumps, reaching 10 million units over the next 5 years, since followed by several country-specific targets. The United States also highlighted heat pumps as a critical technology in its Defense Production Act. Key policy instruments are:

Financial instruments to reduce upfront costs and accelerate deployment: different grants, rebates and subsidies have been introduced or expanded in and , for example, in the United States1 and France.2

Electricity tariffs to motivate fuel switching and account for flexibility: for example, the Electric Ireland Superhome programme contains beneficial pricing for heat pump users and the EU Save Energy Communication highlighted the importance of energy pricing for switching to heat pumps. Rebalancing taxes and levies on electricity and gas could also help improve heat pump competitiveness in many markets.

Mandatory performance-based labels to encourage deployment: for example, in October the energy efficiency labelling scheme for EcoCute3 heat pumps was launched in Japan.

Building codes and standards: for example, in California heat pumps were chosen as a baseline building heating and cooling technology in , meaning that new buildings will have to meet energy efficiency standards equal to or above those of high-efficiency heat pumps. In the Washington State Council updated the commercial building energy code, mandating heating and cooling systems to use heat pumps. In China a new building regulation came into force in , setting requirements for installed HVAC and efficiency improvements.

Renewable and energy efficiency targets and instruments to ban fossil fuels installations: for example, in July the ban on the replacement of oil and coal boilers comes into force under France’s new building code. New York City will follow with the natural gas ban starting from in new buildings up to seven floors high, and from in those over seven stories.

What are the main factors to consider when buying a SPRSUN heat pump?

Size

Air source heat pumps are larger than conventional electric heat pumps and require more space in your home to run efficiently. They are also heavier, which makes it difficult to install them in tight spaces like bathrooms or garages where you want to maximize your space usage. If you have limited storage space, an air source heat pump may not be the best choice for your home or business because you will need to dedicate more space than an electric model would require.

House Location

The first integral component to consider when purchasing an SRSUN air source heat pump is the location of your house. The unit will be most effective at heating the main living area of your home, so if you have a large room with windows on two sides, you'll likely want to opt for a central heating system rather than one in the hallway.

If you have a smaller room or need supplemental heat during the winter months, an air source heat pump may be suitable. You may also find that an air source heat pump can help to save money on energy bills because it doesn't require any fuel to operate and thus requires less gas or electricity than traditional heating systems.

Cooling Capability

Air source heat pumps are designed to provide cooling. They can be used in areas where a water-based system would not be viable due to high humidity or where the load requires more than just air movement.

Efficiency

The other integral factor to consider is the efficiency of the system. An air source heat pump will be more efficient than a ground source system, which means it will use less energy and still produce the same amount of heat. The more efficient it is, the less expensive it will be in the long run.

Air source heat pumps offer higher efficiency than water-based systems. They can recover more energy from the same amount of electricity and be more environmentally friendly.

Space Available

The next factor is your home's space for a new HVAC system installation. This can vary from premise to premise and from room to room within a given house, depending on how large each room is and what kind of heating and cooling equipment might be needed. For example, if there's only one bathroom in your home, you only need a basic unit as opposed to a house with multiple bathrooms due to differences in capacities.

Installation Costs

Air source heat pumps require less maintenance than water-based systems, which reduces operating costs over time.

Noise Levels

Since air source heat pumps do not use water, they are quieter than water-based systems and can be installed in areas where noise could be an issue, such as bedrooms or office spaces, without disturbing other occupants in adjoining rooms or offices.

Comfort Levels

The final thing you should consider is your comfort level with the system. A ground source system will always deliver some form of comfort, whether that is through heat or cooling. An air-source system will not always provide you with any comfort, so if this is something you don't want in your home, then an air-source system may not be right for you.

Conclusion

The air source heat pump is one of the most efficient and environmentally friendly heating systems. It uses a compressor, an evaporator, a condenser, and an electric fan to convert heat from the exhaust air into usable heat in the room.

With the ongoing advancements in air source heat pump accessories, the market is packed with many options, hence the need to choose the best air source heater available. While heat pump units have improved drastically, SPRSUN heat pumps remain the standard-bearer for the ultimate air source heating experience.

With these few tips, you can confidently pick the best air source heater to suit your heating needs.
