Heat pumps are energy savers and can operate in extreme weather. That's why millions of homeowners across the US choose heat pumps as their heating system. But heat pumps are only efficient when they are properly sized. If you buy a small or powerful heat pump for your space, you won't be able to get the best out of your heat pump.
If you're confused about choosing a right-sized heat pump for your space, this article is for you because, in this article, I'll talk about how to choose the right-sized heat pump.
Importance of a Right-Sized Heat Pump
Suppose you'll have to build a house and for that, you'll need 5 workers. But you have hired 3 workers to do the job. So, what will happen? It'll take a lot of time to build the house, and due to excessive workload, workers may not build your house properly. Compare this example with a small-sized heat pump.
When you buy a small-sized heat pump, your heat pump will have to run longer to reach your desired temperature. As a result, you won't be able to get the most out of your heat pump, and you'll notice a spike in the heating bills. Besides, you'll require frequent heat pump repairs.
Again, to build that house, you have hired 7 people. Now, the work will be done quickly, but there will be chaos at work, and you'll have to pay extra money to the extra workers. Compare this example with an oversized heat pump.
When you buy an oversized heat pump, it'll consume more electricity, and you'll have higher electric bills. It'll be an overkill for your heat pump.
But when you buy a right-sized heat pump, you won't have these problems. You'll get the most out of your heat pump, and you'll have lower electric bills. That's why buying a right-sized heat pump is so important.
3 Ways to Choose a Right-Sized Heat Pump
1. Measure the Size of Your House
To buy a right-sized heat pump, at first, you'll have to measure the size of your house. After measuring the size of your house, you'll have to select a heat pump that aligns with the size of your house.
For example, if the size of your house is around 2,000 square feet, you'll require a small-sized heat pump. But if your house is more than 4,000 square feet, you'll require a large heat pump.
Many homeowners ignore the size of their home and buy a powerful heat pump for their home. But this practice must be avoided. You'll have to buy according to the size of your house.
Always remember, the size of a heat pump is proportional to the size of your house.
2. Learn about Your Climatic Region
After measuring the size of your house, you'll have to consider your climatic region because different climatic regions have different heating requirements. For example, if you live in a place where the temperature goes below 25-degree Fahrenheit, you'll need a powerful heat pump to heat your home. On the other hand, if the temperature stays between 40 to 55 degrees Fahrenheit, you'll need a less powerful heat pump.
To better understand your heat pump's size according to your climatic region, you should contact your nearby HVAC professional.
3. Calculate the Heating Required for Per Square Foot
As I mentioned earlier, your climatic region plays an important role in choosing the right-sized heat pump. If you live in a place where the temperature goes below 25-degree Fahrenheit, your heat pump will need 35-40 BTUs of heat per square feet. To know the exact BTU per square feet, you'll have to contact your nearby HVAC professional.
After finding the required BTUs of heat per square feet, you'll have to multiply it by the size of your house. For example, the size of your house is 2,500 square feet, and you need 40 BTUs of heat per square feet. Now, multiply 2500 by 40, and you'll get 100,000 BTUs. This means you'll need a heat pump that can deliver 100,000 BTUs of heat.
Wait, the calculation isn't finished yet. As no heat pump is 100% efficient, and if you buy a heat pump that can deliver 100,000 BTU and has 70% efficiency, you'll get 70,000 BTUs of heat from the heat pump. That's why while buying a heat pump, you'll have to consider the efficiency of the heat pump as well.
To get 100,000 BTUs of heat from the heat pump, you'll have to select a heat pump that can deliver 130,000 BTUs of heat and has 80% efficiency. From this heat pump, you'll get 104,000 BTUs of heat that fulfills your requirement.
