Instead, it is measured the exact same way as your air conditioner – using a SEER value. The efficiency rating of a system is called the coefficient of performance (CoP). A heat pump takes the warm air outside of your home and pumps it inside of your home. An air source heat pump is subject to fluctuating air temperatures and has to work harder to produce heat when the outside air temperature is lower. Air conditioners, on the other hand, may look like a heat pump’s compressor but will only create chilly air. While a heat pump works similarly to an air conditioner, a heat pump is not the same as an air conditioner. They use a refrigerant to warm (or cool in summer months) the air that is being drawn inside. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required. Your heat pump can function as an air conditioner, too. Seasonal Energy Efficiency Ratio is a measure of the seasonal cooling efficiency of a heat pump or a consumer central air conditioning system. It just uses electricity to move the heat, keeping your home comfortable through our cold and rainy Northern California winters. New Zealand is predominantly a heating market – what is globally considered an air-conditioner is purchased by New Zealand consumers as a heat pump. Efficiency and performance deteriorate if airflow is much less than 350 cfm per ton. If you're dreaming of a toasty warm home for winter, these models might leave you a bit cold. Refrigerant is used to heat the coils and the heated air is then pushed back into the room. Today's heat pump can reduce your electricity use for heating by approximately 50% compared to electric resistance heating such as furnaces and baseboard heaters. It provides high-efficiency cooling in the summer, and efficient heating in the winter. The optimal temperature range for conventional air source heat pump operation is above 25 to 30 degrees Fahrenheit. While an air conditioning unit moves warm air from inside the house outside, a heat pump does just the opposite. This heat pump gives you four operations all in one purchase. A heat pump is energy efficient because it moves heat instead of generating it. The ENERGY STAR Most Efficient 2020 designation recognizes the most efficient products among those that are ENERGY STAR certified. Myth #2 – A heat pump is the same as an air conditioner . In the end, this comes down to the cost of gas vs. cost of electricity. When looking at a cooling system, you also may see a Seasonal Energy Efficiency Ratio (SEER) rating. Built for maximum efficiency, its heat pump can produce heat at a rate of 9000 up to 36,000 BTU per hour. This means that in the colder months, when the heat pump is likely to be relied on the most, it will use more units of electricity to produce the same amount of heating as a ground source heat pump in the same period of time. However, because a heat pump moves air from one place to another, it won’t work well in places where there isn’t much heat to be found. A 13 SEER air conditioner cools as efficiently as a 13 SEER heat pump. To install the most common type of heat pump—an air-to-air model—you’ll pay an average of $3,500 to $4,500, depending on size and efficiency. The heat pump looks like the outdoor air conditioning unit and works similarly. The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air. Reverse cycle air conditioners, or heat pumps as they're commonly known, work by extracting heat from outside air and transferring it inside. The unit comes with a wall-mount, ductless indoor section, and a heat pump outdoor section. A heat pump reverses the cooling cycle of the PTAC air conditioner. Heat pump efficiency is measured by its Coefficient of Performance (CoP), which shows how efficiently the ground and air source heat pump systems can heat your home under the best possible conditions. So basically, it’s an air conditioner that can reverse itself. In many ways, heat pumps are functionally the same as conventional air conditioners. How air-source systems work. But if it's negative 22 degrees out like it gets here in Bozeman, Montana, then there isn't much heat to take out of the air to heat your home, right? Air conditioning and heat pump energy efficiency is measured by SEER which stands for Seasonal Energy Efficiency Ratio. Heat pumps - like air conditioners - work by removing heat from the air (instead of creating heat, like a furnace does). Because a heat pump, which will be discussed in more detail later, is basically an air conditioner that has the ability to run in reverse, heating your house instead of cooling it. Using this scale, commercial air source heat pump efficiency can be as high as 4, whereas ground source heat pumps can reach up to 5. The heat pump efficiency factor is pretty high, and heat pumps are often less expensive than other types of heat. There are actually three types of heat pumps: Air-to-air, water source and geothermal. Heat pumps are powered by electricity, so fuel isn’t used. Not ideal for harsh climates - Heat pumps are not as efficient in extreme temperatures. That's why heat pumps don't work well below freezing temperatures. Adding a heat pump in Seattle homes is a good investment. It is getting more popular across the United States because of its cost-efficiency and functionality. What is Central Air? Heat pumps are already at a price disadvantage when it comes to initial investment (not long-term savings) compared to conventional heating solutions like boilers, so the drive towards more efficient heat pumps and air conditioners is often led by legislative measures on minimum efficiency standards. How a Heat Pump Is Superior to an A/C. You only need to compare the cost of using a heat pump vs. the gas furnace. A heat pump will provide you great comfort in winter as well as in summer. To warm your home, a reversing valve in the heat pump switches the flow of refrigerant. It provides you air conditioning, heating, ventilation, and dehumidification. Comparing a geothermal vs. air-source heat pump is one of the first decisions you will make when shopping for a new heat pump air conditioner system. HSPF = (120000000 Btu) / (1000 (15000 kWh)) = 8.
