Why Bigger Heat Pumps are Not Always Better
Is it better to buy a bigger heat pump? Well, heat pumps offer incredible benefits, but they're not one-size-fits-all. Heat pumps vary in size according to their intended use and required capacity for heating or cooling. A wrong size selection can have a negative impact on your wallet, comfort, and health. Here we have explained why you should choose the right size for your home or building instead of the largest.
The Problems Associated with the Use of Larger Heat Pumps
Larger Models Cost You More Up Front
Oversized heat pumps are generally more expensive, which can increase your upfront costs without providing any additional benefits. Bigger heat pumps are more expensive because more materials and components are used to manufacture them. Furthermore, larger units require larger compressors, fans, and heat exchangers, contributing to the higher cost. Moreover, installing an oversized heat pump may require more work and equipment. Installing a bigger unit will require more electrical service and ductwork, which can cost more.
Oversized Systems Run Less Efficiently
An oversized heat pump might look attractive to people who want their home or office always to feel just right. However, it can actually lead to decreased efficiency and higher energy bills. It is because oversized heat pumps run less efficiently. An oversized heat pump installed in a smaller space will cycle on and off more frequently than an appropriately sized unit, which can reduce efficiency. Since the heat pump's runtime is short, it will not have adequate time to reach its peak efficiency. As a result, an oversized heat pump will consume more energy to maintain consistent temperature and humidity levels.
More Wear and Tear and Reduced Lifespan
An oversized heat pump will likely cycle on and off too often, resulting in inefficient operation and increased wear and tear on the unit. The constant wear and tear ultimately reduce the unit's lifespan. It affects multiple components of the heat pump unit, including the compressor, fan and heat exchanger. The increased cycling of an oversized heat pump can cause several issues that can damage the unit. It can lead to premature failure of different components of the heat pump unit. Additionally, an oversized unit may experience more refrigerant leaks, leading to costly repairs and a shorter lifespan.
Oversized Heat Pumps Cause Moisture Problems
During the condensing process, warm, damp air runs over a cold coil, resulting in water condensing out. If the system is of the appropriate size, it continuously dehumidifies and cools the space. Oversized systems, on the other hand, don't run long enough for the system to dehumidify the air sufficiently. It will make the space cold and clammy, causing rot, mould, and respiratory problems.
How to Buy an Ideal Heat Pump?
What can you do to ensure your heat pump is the right size? The first thing you should do is to get an accurate estimate of your heating and cooling loads. You can have your contractor assess them or hire an energy consultant. Keep your home comfortable instead of clammy on the hottest days by selecting a minimum capacity matching your cooling load. Besides your home's heating and cooling needs, consider your local climate, home size, and the number of residents to determine your home's ideal heat pump size.
