Portable Heat Pumps: Efficient Heating and Cooling for Smaller Spaces

Small Heat Pump

If you’re looking to heat or cool your tiny home more cost effectively, heat pumps might be the solution you’ve been looking for. These versatile and compact appliances offer both heating and cooling functions, making them perfect for small apartments, rental properties, and those who need a customizable climate solution. In this blog post, you’ll learn everything you need to know about portable heat pumps, including their functionality, energy efficiency, installation, maintenance, and smart controls. Let’s dive in!

Key Takeaways

  • Portable heat pumps offer portability, safety, energy efficiency and personalised spot heating/cooling.

  • Consider type of pump, cooling/heating capacity & SEER/HSPF ratings for optimal performance & energy savings.

  • Advantages include cost efficiency vs traditional HVAC systems. Drawbacks may include noise level and placement restrictions.

Understanding Portable Heat Pumps: Functionality and Features

Portable heat pumps, a marvel of modern technology, deliver both heating and cooling functions in one compact unit. Their biggest advantages are:

  • Portability: They can be easily moved from one room to another.

  • Safety: They are notably safer than space heaters.

  • Energy efficiency: They consume less energy and save you money on electricity bills.

  • Personalized spot heating and cooling: You don’t need to waste energy on heating or cooling unoccupied areas of your home.

However, not all portable heat pumps are created equal. There are a few key factors to consider when choosing the right unit for your needs, such as the type of heat pump (single or dual hose), cooling and heating capacity, and energy efficiency ratings. Fortunately, we’ve got you covered with all the information you need to make an informed decision.

Types of Portable Heat Pumps: Single vs. Dual Hose

When it comes to portable heat pumps, there are two basic types: single hose and dual hose models. Though single hose models prove more economical and easier to move, they generate negative air pressure and necessitate a constant air supply. In contrast, dual hose models, with their superior efficiency, are optimal for heating or cooling larger rooms.

The main difference between single and dual hose portable heat pumps is their method of drawing air. Single hose models draw air from the interior of the room, whereas dual hose models obtain air from the exterior via two distinct hoses. This difference in air intake can have a significant impact on the overall efficiency and performance of the heat pump. Therefore, it’s crucial to carefully consider your specific needs and room size when choosing between single and dual hose models.

Cooling and Heating Capacity

One key factor to consider when choosing a portable heat pump is its cooling and heating capacity, which is measured in British thermal units (BTUs). The general rule of thumb for calculating the required BTUs for a given room size is to use 20 BTUs per square foot of living space. For example, if your room is 400 square feet, you’ll need a heat pump with a capacity of approximately 8,000 BTUs.

Choosing a portable heat pump with the correct capacity for your heating and cooling needs is pivotal. A higher capacity means the heat pump can provide more efficient heating and cooling for a larger area, while a lower capacity may restrict the coverage area and may not be suitable for larger spaces. By choosing the right capacity, you can ensure optimal performance and energy efficiency.

Energy Efficiency and Eco-Friendliness

Energy efficiency and eco-friendliness are among the primary benefits of portable heat pumps. These units consume less energy than traditional heating and cooling systems, which means you can save money on electricity bills and reduce your carbon footprint. To ensure you’re getting the most energy-efficient unit, it’s important to consider factors such as the SEER/HSPF ratings and Energy Star certification.

In addition to their energy efficiency, portable heat pumps also offer a more sustainable and eco-friendly solution compared to other cooling and heating systems. Here are some benefits of portable heat pumps:

  • They provide both heating and cooling functions in a single unit, reducing the need for multiple appliances.

  • Their portability allows for spot cooling and heating, minimizing energy waste.

  • They help you enjoy comfortable indoor temperatures while doing your part to protect the environment.


In assessing the energy efficiency of a portable heat pump, its SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings warrant consideration. These ratings measure the cooling and heating efficiency of portable heat pumps, respectively. The higher the ratings, the better the performance and energy savings. In the United States, the minimum SEER ratings are 14 in southern states and 15 in northern states, while the minimum HSPF rating is 8.8 as of 2023.

The average range of SEER/HSPF ratings in currently available portable heat pumps is between 13 and 25 for SEER ratings and between 7.5 and 8.5 for HSPF ratings. By choosing a heat pump with higher SEER and HSPF ratings, you can ensure that your unit operates efficiently, reducing energy consumption and cost while providing optimal heating and cooling performance.

Energy Star Certification

When searching for an energy-efficient portable heat pump, Energy Star certification is another key factor to take into account. Heat pumps with this certification have been proven to use 20% to 50% less energy than other units. To achieve Energy Star certification, heat pumps must have a SEER rating of 15 or higher.

The certification process involves third-party verified performance testing for low temperatures, with testing conducted down to 5°F. By choosing an Energy Star-certified heat pump, you’re not only ensuring increased energy efficiency but also contributing to a greener and more sustainable future.

Installation and Maintenance of Portable Heat Pumps

The relative simplicity of installing and maintaining portable heat pumps makes them an appealing choice for numerous homeowners and renters. There’s no need for any complex installation process, as these units can be easily installed anywhere by extending a flexible hose through a window to vent the air outside. However, it’s essential to consider factors such as the window kit and venting requirements to ensure proper installation and optimal performance.

Regular maintenance is also vital for your portable heat pump to extend its lifespan and uphold its efficiency. Cleaning and maintaining a portable heat pump typically involves vacuuming the unit and checking for any signs of damage or deterioration, as well as cleaning or replacing the filters every few weeks.

Window Kit and Venting

A window kit, facilitating the creation of an exhaust air vent opening without necessitating permanent alterations to windows, doors, or walls, is a critical component in the installation of portable heat pumps. It’s essential to measure the dimensions of your window to ensure the venting kit, including the exhaust hose and exhaust pipe, will be long enough for the window frame.

Various window kits are available for portable heat pumps, such as:

  • Push/pull window kits

  • Adjustable universal window kits

  • Plastic bar window kits

  • Cool seal window kits

By choosing the right window kit for your needs, you can ensure a proper and efficient installation, maximizing the performance and energy efficiency of your portable heat pump.

Cleaning and Maintenance Tips

Maintaining cleanliness and upkeep of your portable heat pump is vital for its optimal performance and longevity. It’s recommended to clean or replace the filters every 4 to 12 weeks, depending on how often you use the heat pump. Regularly inspecting the unit for any signs of damage or deterioration and taking action immediately can prevent further issues and extend the unit’s lifespan.

In addition to regular cleaning and maintenance, it’s important to ensure proper air circulation around the unit. Keep the heat pump at least 20 inches away from walls or large furniture and avoid hiding the unit behind plants or other objects. By following these simple tips, you can ensure your portable heat pump remains efficient and effective for years to come.
