You may or may not have heard of a heat pump, a relatively new kind of heating system that’s gaining popularity across the country. Even if you have heard of it, you may not know how it works or why it’s worth choosing over a more traditional system. For those of you who are curious about the benefits of a heat pump, you’ve come to the right place. Read on to find out how a heat pump actually works, and what kinds of benefits it can provide.
What is a Heat Pump?
A heat pump is a non-combustion based system. That is, it does not burn fuel in order to create heat. Instead, a heat pump moves preexisting heat from a space that doesn’t need it to a space that does. It does this by utilizing two different parts of the system, an indoor unit and an outdoor unit. The outdoor unit is installed outside, while the indoor unit is installed inside, as you may have guessed. The two units are connected to each other by power and refrigerant lines.
When the heat is turned on, the outdoor unit evaporates refrigerant using a coil inside its casing. The gaseous refrigerant acts as a heat sink, pulling thermal energy from the surrounding air and into the coil. The thermal energy is then carried down the refrigerant line and into the indoor unit. There, the refrigerant gas is condensed back into a liquid state. This releases the thermal energy to warm the air before circulation.
There are multiple benefits to installing a heat pump in your home. The first is that a heat pump system is much more energy efficient than combustion systems. It only has to use electricity to operate, and garners the entirety of its heat from the surrounding environment.
The second benefit of a heat pump is that it can actually act as both an air conditioner and heater. It does this by simply reversing the flow of refrigerant through the system, taking heat from the house and releasing it outside. This saves you the space and expense of installing an entirely new system.
