Understand Heat Pump And Its Benefits First
Acquiring a comprehensive understanding of a heat pump is crucial before delving into the appropriate size selection. Essentially, a heat pump is an innovative HVAC system that operates on electricity, allowing it to transfer heat from the external environment to the inside of your home or vice versa. During the summer, the heat pump extracts heat from the inside of your home and releases it outside, while in the winter, it draws heat from the outdoor environment and brings it indoors. Familiarizing oneself with the unique attributes of a heat pump is paramount to maximizing its benefits and optimizing its functionality.
Benefits Of Correctly Sized Heat Pump
- Lower energy bills: A heat pump is an efficient HVAC system that uses electricity to transfer heat, which can result in lower energy bills compared to traditional heating and cooling systems.
- Consistent temperature: A heat pump maintains a more consistent indoor temperature by continuously monitoring and adjusting the temperature as needed.
- Eco-friendly: A heat pump uses electricity to transfer heat, a more eco-friendly alternative to traditional heating systems that burn fossil fuels.
- Long lifespan: A well-maintained heat pump can last up to 20 years, making it a long-term investment for your home.
- Quiet operation:Â Heat pumps operate quietly, making them a good option for homes in noise-sensitive areas or for people who prefer a quieter home environment.
By selecting the right size and type of heat pump for your home and working with an experienced professional like HVAC Warehouse, you can enjoy these benefits for years.
What Happens When Heat Pump Is Oversized or Undersized?
- Undersized Heat Pump:
If a heat pump is undersized, it will struggle to keep your home warm on the coldest days. If you have electric resistance heat as a backup, your home will stay warm, but it will increase your electricity bills significantly. However, a correctly sized heat pump can work efficiently even in colder climates.
- Oversized Heat Pump:
Most heat pumps have variable speed motors, which adjust the heating or cooling based on the temperature outside, providing a comfortable temperature consistently. But an oversized unit will kick on and off frequently, even a variable speed model, as its lowest speed might still overheat your home. In humid parts of the country, this problem worsens as heat pumps act as dehumidifiers. An oversized system spends most of its time off, allowing moisture to build up, leading to mold growth. Oversized units result in a less comfortable home, with hot and cold spots instead of a steady temperature throughout the house. Besides the higher upfront cost, an oversized unit must be replaced sooner than a correctly sized unit, leading to more wear and tear.
Is There Any Rule Of Thumb To Rely On?
Rules of thumb like “you need 30 BTUs of heat for every square foot of living space you want to heat or cool” or dividing the total square footage of a home by 500 to estimate the heat a home needs are inaccurate. These rules of thumb are almost always wildly inaccurate. For example, the closest heating load using the first rule of thumb was off by 12,000 BTUs, or one ton. On average, this rule of thumb oversized heat pumps by 31,000 BTUs. The second rule of thumb, dividing by 400, provided more accurate estimates. But 32% of homeowners would still have a seriously undersized unit. Rules of thumb and online calculators are inaccurate ways to size a heat pump.
It is not advisable to depend solely on internet-based calculators for determining the right heat pump for your home’s heating and cooling needs. Investing in a heat pump entails a significant financial commitment and impacts your home’s indoor air quality and comfort. Therefore, it is crucial to seek the assistance of our experienced professional. They can accurately size and select the right heat pump for your specific requirements. Moreover, professional installation by HVAC Warehouse will ensure optimal performance and long-term efficiency of your heat pump.
How To Size A Heat Pump?
There are two ways to size a heat pump accurately. One involves an experienced contractor or building performance contractor, and the other requires a smart thermostat.
- Get a Manual J Load Calculation and Blower Door Test:
The safest and easiest way to determine the heat pump size needed is to work with an experienced contractor or get an energy audit. In both scenarios, someone will conduct a Manual J Load Calculation and Blower Door Test. The Manual J Load Calculation determines the home’s heating and cooling needs to be based on factors like square footage, insulation, windows, and doors. A blower door test determines the air leaks and the amount of air exchanged per hour, critical factors for determining the size of the heat pump.
- Use a Smart Thermostat:
The other way is to use a smart thermostat to track energy usage, and the time the heat pump takes to achieve a set temperature. Using this data, the smart thermostat can closely estimate the heating or cooling capacity needed for your home. This method is not as accurate as a Manual J Load Calculation and Blower Door Test, but it is still a practical option.
