What Is a Heat Pump? Simply put, a heat pump moves heat from one place to another. Get Maintenance Benefits. A heat pump is an HVAC system that transfers heat from one place to another. By understanding the basics of how a heat pump works, you can better decide if this is the right option for your home. Additionally, regular maintenance of your heat pump can provide several advantages.
Heat pumps are versatile HVAC systems that can both heat and cool your home. They work by transferring heat instead of creating it, making them more energy-efficient than traditional furnaces and air conditioners. Here’s how they work:
Types of Heat Pumps:
There are a few different types of heat pumps on the market, each with its own benefits and drawbacks:
• Split-ductless: This is the most common type of heat pump. It has a larger outdoor unit and a smaller indoor unit that is mounted on the wall or ceiling.
• Single-duct: This type of heat pump has only one outdoor unit and uses ductwork to distribute air throughout the home.
• Geothermal: This type of heat pump uses the earth’s natural warmth to heat and cool your home. It requires loops of pipe to be buried underground, making it the most expensive option.
How Heat Pumps Work:
Heat pumps work by using a refrigerant to transfer heat from one place to another. In heating mode, the system:
1. Collects heat: The heat pump gathers heat from the air or ground outside, even when the temperature is cold.
2. Compresses the refrigerant: The pump compresses the refrigerant, which increases its temperature.
3. Transfers heat indoors: The hot refrigerant then flows through coils inside the home, transferring heat to the air.
In cooling mode, the system works in reverse:
1. Collects heat indoors: The heat pump pulls heat from the air inside the home.
2. Transfers heat outdoors: The heat is then transferred to the refrigerant and released outside.
Benefits of Heat Pumps:
• Energy-efficient: Heat pumps can be up to three times more efficient than traditional furnaces and air conditioners.
• Environmentally friendly: Heat pumps do not produce any emissions, making them a more eco-friendly option.
• Year-round comfort: Heat pumps can provide both heating and cooling, eliminating the need for two separate systems.
Drawbacks of Heat Pumps:
• Higher upfront cost: Heat pumps are typically more expensive than traditional furnaces and air conditioners.
• Limited efficiency in extreme temperatures: Heat pumps may not be as efficient in very cold or hot climates.
• Backup system needed in some cases: In some climates, a backup heating system may be needed for very cold days.
Heat pumps are a great option for homeowners who are looking for an energy-efficient and environmentally friendly way to heat and cool their homes. However, it is important to consider the upfront cost and potential need for a backup system before making a decision.
Airsource heat pump
• Heat Source: Outdoor air
o Outdoor unit
o Indoor piping system
o Optional air-source hot water heat pump
o Easy to install.
o Less expensive than ground-source pumps
o Can be paired with an air-source hot water heat pump for hot water.
o Less efficient than ground-source pumps in extreme temperatures
o Limited by outdoor air temperature
• Ideal for: Homes in mild climates with limited space
• Heat Source: Ground temperature (approximately 50°F)
o Outdoor unit
o Buried looped pipe system.
o Indoor piping system
o More efficient than air-source pumps, especially in extreme temperatures
o Consistent performance year-round
o Longer lifespan
o Higher upfront cost
o Requires more space for installation of the buried pipe system.
• Ideal for: Homes in any climate with enough space for the pipe system
