How Exactly Does A Mini Split Heat Pump Work?

In non-mechanical terms, ductless mini split heat pumps basically extract heat from the outdoor surroundings and bring it inside to warm the indoor temperature. 

The heat pump’s refrigerant does its job to deliver this process. As the outdoor air moves across the coils of the mini split unit, the heat energy soaks into the coil. The coil captures the heat. As the heat moves through the system of the mini split, its liquified gas gets warmed up into a vapor. The vapor then goes through the fan, to which air is pushed indoors. The end result is a warm and comfortable indoor temperature. 

Despite its name, mini split heat pumps also double as an AC system. During the summer months, when you need cold air more than warm air, the system can be reversed to produce colder air instead. 

Ductless mini split heat pumps are more energy efficient compared to other conventional heating systems. This is due to its heating process. Instead of generating heat, it moves heat from the outdoors to indoors. 

Mini splits can be single or multiple zones. Single zones consist of one indoor unit and one outdoor unit. For multiple zones, one outdoor unit connects up to 8 indoor units. 

Mini Split Heat Pump System: Types of Indoor Units

Indoor unit installations vary in most residential homes. The reasons behind this are the layout of the space, the available wall space, or simply for aesthetic and personal preferences. Three types of indoor units include wall-mounted, floor-mounted and ceiling mounted. 

Wall Mounted Units

Units that are wall mounted can be seen elevated from the floor and a few inches from the ceiling. This type of installation is said to be the most efficient and best coverage compared to the other two types of indoor units.

The pros of this indoor unit have a higher air flow rating and easier installation. The wall mounted unit is capable of moving more air and covers more square feet. It is also easy to install with very minimal wall modifications.

A wall bracket is usually the commonly used accessory to mount the indoor unit on the wall. Since the unit is wall-bracketed, it is required to have an 18 to 22 inch height distance from any object. It also consumes 40 inches or more of available space. 

Floor Mounted Units

These units are bracketed on the floor. They take up more square footage on the wall compared to wall mounted units. These units are ideal for spaces with inadequate wall space.

The airflow rating of these units is still high and it works under large windows that prohibit wall-mount installation.

The disadvantages of floor mounted units are their size and efforts to install them. They are quite larger than most wall mounted units and they require more time to bracket. 

Ceiling Mounted Units

These units are usually installed in office hallways as they release air in four different directions.The advantages of ceiling mounted units include the space it occupies and the direction of heat release.

In terms of occupied space, it does not require wall space, as it is installed on the ceiling and it can distribute heat evenly across the room, especially when placed in the center.

The only disadvantage of ceiling mounted units is the amount of time and effort to install them. Most of the time, an HVAC professional needs to be hired because installation is done in the attic. 

Different units work with different home structures and layouts. Each also provides satisfaction for customers’ varied preferences and needs.

Choose from three types of indoor units according to your home layout to avoid faulty installations. You do not want a holed up wall or ceiling after deciding that the unit on hand is not the best one for you. 


Tips to Get More from Mini-Split Heat Pumps in Colder Climates

  1. First order of process: Reduce Load
  2. Size the Unit Right
  3. Put A Roof
  4. Install It Down-Low
  5. Get The Pipe Size Right

First order of process: Reduce Load

By improving the thermal envelope of the structure, you also minimize the size you will need and definitely reduce overall energy consumption. Before purchasing a mini split heat pump system, check for the Energy Star rating of the thermal envelope.

Most of the time heat pump furnaces and AC split systems are composed of ultra-efficient thermal envelopes that allow optimal use of energy. 

Size It Right

Take note that once the outdoor temperature drops, the heat pump output drops as well. The recommended sizing must meet a heating load of 10 degrees Fahrenheit.

The majority of mini split heat pump systems in the market offer such heating load requirements. Also, it is important to remember that most heat pumps do not have the capacity to immediately bring up the temperature. In a 50 degree Fahrenheit setting, you can do the job overnight. 

Put A Roof

As a prevention measure, make sure to put a roof on top of your outdoor unit. Make sure to mount your outdoor unit at least 2 feet above ground. This is mostly true for regions with colder climates all year round. Although mini-split heat pump systems have a defrost cycle, it still consumes extra energy, thus, a little protection from the cold weather will do the trick. 

Install It Down-Low

The indoor unit is suggested to be mounted about 18 inches off the floor for a good, clear shot into the living space. Mounting the unit low has many benefits for heating. It operates more efficiently because it is pulling in cooler air to warm up the space.

The warm air is also blown out across the floor and mixes with the cold air at floor level, for a balanced spread of warm air. Lastly, the air will not blow directly on occupants and it makes it easy to access the filters for cleaning.

Get The Pipe Size Right

At least 15 feet of piping ensures no noise transfer from the compressor to the indoor unit. Despite the noise being reduced by longer lengths of tubing, it will lower efficiency. Consult the manufacturer for the right size of piping for indoor and outdoor units in order to reduce the noise and achieve maximum efficiency at the same time. 


Ways to Save Energy When Using Mini-Split Heat Pumps

  1. Seal Openings
  2. Involve the Fans
  3. Insulate Floors
  4. Adjust the Thermostat
  5. Optimize Layout

Seal Openings

By simply installing weather–stripping around your windows and doors you are able to keep the cold out. Leaky doors and windows are not a pain as much as poor insulation, but they’re a close second. The mini-split heat pump industry offers sealant accessories for homes with wide openings after systems installment. Be sure to get yourself one to allow your heat pump system to perform easily and consume energy efficiently.

Involve the Fans

Mini split heat pump systems can use the help from other home equipment and appliances. Particularly a ceiling fan.

The reversible function is an important setting your ceiling fan could have.  Setting it to rotate slowly clockwise will circulate warm air down to where people are, and help regulate the temperature in your rooms as released by the heat pump. With this, you do not have to set the temperature at such a high level and consume more energy.

Insulate Floors

Wood and tile floors are the commonly used flooring in most residential homes. For one, it is because they are aesthetic and functional but they are also cold in winter.

Be aware that up to 10% of your home’s heat loss comes from your uninsulated floors. You have two options that vary in efficiency. The first is to insulate your flooring with actual insulation. If it is not practical, or yet affordable, go for an easier fix. Add area rugs across the space. 

Adjust the Thermostat

Might seem counter intuitive but keeping the temperature lower than normal allows slower heat loss. This translates to lesser electricity increase and you save money. The less time the mini split unit has to be turned on, the better.

There are two ways to adjust indoor temperature according to your activities. It is either have a Wi-Fi capable thermostat, so you can access it using your mobile phone or get into the habit of manually adjusting the thermostat. 

Optimize Layout

The question that matters here is, “What area is the coldest in your home? Or space?”. Probably the area near the windows? The best move is to transfer your furniture, especially couches so that you will not have to sit up against the cold area. Your body heat is what makes you comfortable. 

Similarly, avoid putting your furniture in front of floor vents, wall vents, or radiators. They will consume all the heat and your heating system will have to work harder to bring your air up to your desired temperature.
