Difference between Heat Pumps and Mini-Split systems
If you don't study a topic on a regular basis and suddenly have to "dive into" it, you may feel uncomfortable. In this situation, you need to spend some time and effort to find the answers and feel "in the material". The subject of HVAC systems is no exception. And even if you are already using certain solutions, new products are not always clear. So if you are trying to understand what a heat pump or a mini-split system is and if there is a difference between them, we will help you find the answer.
In short, a heat pump and a mini-split system are closely related, but there are differences between them. So let's try to figure out what one is and what the other is.
What Is a Heat Pump?
A heat pump is a type of HVAC system that can both cool and heat a room. It works by transferring heat between the external and internal environments. In cooling mode, it extracts heat from the inside and releases it to the outside to cool the room. In heating mode, it extracts heat from the outside air (even at low temperatures) and transfers it to the inside of the room to heat it.
What is a mini-split system?
A mini-split system is a type of heat pump that does not require ductwork to distribute air. It consists of two main components: an outdoor compressor/condenser and one or more indoor units. These indoor units are usually wall-mounted and connected to the outdoor unit by a pipe containing refrigerant lines and power cables. A nice feature of mini-split systems is that they can be installed in spaces that are traditionally difficult to heat and cool, such as a garage or an extension to a house.
Key Differences
- Ductwork: A traditional heat pump system may rely on ductwork to distribute air throughout the home, while a mini-split system does not require ductwork. This makes mini-splits ideal for homes without existing ductwork, or for certain areas where ductwork is impractical.
- Zoning capability: Mini-split systems inherently offer zoning capability because each indoor unit can be controlled separately, allowing you to adjust the temperature in different rooms or areas of the home. Heat pumps with ducted systems may require additional equipment for zoning.
- Installation and Flexibility: Mini-split systems are generally easier to install than traditional heat pumps, especially for retrofits, because they do not require extensive ductwork. They offer more flexibility in indoor unit placement, allowing for more targeted heating and cooling of the space.
Heat Pump or Mini-Split – Which is Better?
A mini-split system typically costs more to purchase and install. This is due to the need to use multiple air conditioners. However, for your money, you get benefits such as zone control and the ability to cool/heat specific rooms. And the long-term benefits of more efficient energy use will have a positive impact on your utility bills.
