How Heat Pumps Work
How do heat pumps manage to both heat and cool your home? It's all about transferring heat, rather than generating it. In cooling mode, a heat pump works like an air conditioner, extracting heat from inside your home and releasing it outside. In heating mode, it reverses this process, capturing heat from the outdoor air (even in cold weather) and moving it indoors.
The key components of a heat pump include a compressor, two heat exchanger coils (one indoor and one outdoor), and a reversing valve. Refrigerant circulates through these components, changing state between liquid and gas to absorb and release heat. The compressor pressurizes the refrigerant, while the coils facilitate heat exchange with the air.
When heating, the outdoor coil acts as an evaporator, absorbing heat from the air. The compressed refrigerant then moves to the indoor coil, where it condenses and releases heat into your home. For cooling, the process reverses, with the indoor coil absorbing heat and the outdoor coil releasing it. This versatile operation makes heat pumps an efficient, year-round climate control solution.
Types of Heat Pumps
There are three main types of heat pumps you'll encounter in residential settings: air-source, ground-source (geothermal), and water-source.
Air-source heat pumps are the most common and cost-effective option. They extract heat from outdoor air and transfer it inside during winter, reversing the process for cooling in summer. These units work well in moderate climates but may struggle in extreme temperatures.
Ground-source heat pumps, also known as geothermal systems, use the earth's constant underground temperature to heat and cool your home. They're more expensive to install but offer higher efficiency and lower operating costs over time. You'll need sufficient land for the underground loop system.
Water-source heat pumps operate similarly to ground-source systems but use a nearby water body as the heat source or sink. They're ideal if you have access to a pond, lake, or well. These systems are highly efficient but require specific site conditions.
Each type has its pros and cons, so you'll need to consider factors like climate, property characteristics, and budget when choosing the best heat pump for your home. Consult with a professional to determine which option suits your needs.
