A ductless mini-split heat pump, commonly referred to as
"mini-split" and "zone HVAC," is a heating and cooling
system that works without the use of ducts.
Therefore, ductless air conditioners are a great option for homes that
are doing additions or renovations and don't have room for ducts. Ductless
units may be the best option when expanding or building new ductwork is too
difficult or impractical.
How does a heat pump work in winter?
When it's hot outside and the "cold" setting is selected on
the thermostat, the heat pump operates like an air conditioner or refrigerator.
It absorbs heat from the hot interior air and sends it outside through
refrigerant pipes. When your heat pump is set to heat, the process is reversed
in winter: the heat pump can warm your home by removing heat from the outside
air and transferring it inside.
You might be thinking, "But how does a heat pump collect heat from
the outside air when it freezes?". Heat pumps are specially designed to
efficiently collect even trace amounts of heat, which can be converted into
warm air for you and your family.
When should a cold weather mini split heat pump be used?
When used in cold climates, ductless heat pumps can replace (replace)
existing resistive heating systems in the main body of the house, such as
skirting boards or wall heaters, and provide primary heating. Less expensive
non-cold climate ductless heat pumps will not be effective when temperatures
drop below freezing, significantly reducing energy efficiency.
Types of Our Cold Weather Mini Split Heat Pumps:
1. Mini split heat pump
This mini-split can be used as a
winter heater, summer cooler and dehumidifier to keep your home at the correct
humidity level all year round.
On top of that, one of the great things about a micro-split heat pump is
that it's very quiet, even with all its great features and power efficiency.
It's the perfect solution for people who have trouble falling asleep due to
2. Wall Mounted Ductless Mini Split Heat Pump
This product is attractive due to its excellent efficiency. It has a
SEER rating of 17 and an HSPF of 9. Smart inverter technology combined with
inverter variable speed compressors significantly reduces energy consumption.
At the same time, it provides the capacity needed to maintain the
desired room conditions. If you only have one room or a small house, this heat
pump is perfect for you.
This model features a wide-angle blind design, automatic swing and
comfort mode controller settings that confirm you're enjoying maximum comfort
with proper heating and cooling throughout the space.
3. Mini Split Air Conditioner Ductless
With a SEER rating of 22, it is the most energy efficient cooling
option. Indeed, the SEER and HSPF ratings of the smaller mini-split heat pumps
are higher than the larger ones. However, the 22 SEER rating is 10% more energy
efficient than the 20 SEER rating. This way you can save $10 to $20 in cooling
10 HSPF is also one of the best protection factors available. As a
result, the Della 048-MS-24K2V-17S-I has a noise level of 49 dB, slightly
higher than the quietest heat pump.
4. Ductless Small Split Heat Pump
Undoubtedly, the unit has a maximum efficiency of around 12,000 BTU/H
and a SEER rating of 17.5. It's an excellent investment as it runs quietly and
has excellent cooling and heating standards.
The cooling and heating capabilities of this tiny split unit show how
well it performs in hot and cold regions. Thanks to its staggering 12,000BTU/H
and SEER rating of 17.5 points, this unit is the best buy. It's designed for
anyone who wants a high-quality performer in any setting.
5. Ductless Mini Split Air Conditioner
It is a truly amazing product due to its versatility. This small split
system can operate in a variety of climatic conditions despite outputting as
low as 9000 BTU/H. It has a SEER rating of 19 and is a 4-in-1 humidifier, air
conditioner, heater and fan.
It works in a variety of climates, making it a viable option for any
foreign market. Its 4-in-1 design makes it perfect for any environment. With
its Low Ambient Kit and Whisper Technology, it can run completely silent down
to a frigid 5F.
6. Mini split air conditioner/heater
This heat pump is available in a variety of BTU capacities including
9,000, 12,000, 18,000, 24,000 and 30,000.
Essentially, a SEER rating of 20.5 and an HSPF rating of 10 guarantees
that you will consume less energy than a regular heat pump and ultimately save
A 24,000 BTU heat pump can operate efficiently with an airflow of 618
CFM. It is also one of the quietest heat pumps on the market, with a maximum
noise level of 47.5 dB, even at maximum fan speed.
Size of heat pump
Make sure your mini-split heat pump is the right size. In most cases,
small split systems are used to heat individual rooms in your home. Units are
available in a variety of sizes and configurations. Consult an installer or a
reliable source to ensure proper installation of the required equipment.
You can also estimate the heat pump size you need in this calculator.
Energy efficiency rating
The EER or Energy Efficiency Ratio, which is a standardized assessment
of a unit's overall energy efficiency level, should also be taken into account.
The Energy Efficiency Ratio (EER) measures how well a device performs while
Heat pumps with an EER rating of 12 to 21 (seasonal EER) and an HSPF
rating of 8 to 10 are generally considered the most energy efficient.
Consider the noise level of your machine before buying as it can have a
major impact on how you use it.
Due to its small size, this is one of the quietest air conditioners you
will find. Ultra-quiet heat pumps typically have a decibel range of 40 to 50,
making them quieter than light rain or a running dishwasher.
When comparing different heat pump systems to meet your heating and
cooling requirements, keep an eye out for AHRI certification. Air Conditioning,
Heating and Refrigeration is known in the industry as AHRI. AHRI can certify
appliances and machines as long as they meet efficiency standards. One
technique for comparing small split heating and cooling systems is to look for
AHRI certification. If the differential is not certified, it is recommended not
to buy it.
All small split systems require regular maintenance. To keep your system
running smoothly and efficiently for as long as possible, follow these basic
Make sure the indoor head/cassette filter is cleaned every 3-4 months.
Make sure that external equipment is free of debris that could obstruct airflow
or clog the drainage system.
Regularly check the outdoor unit to ensure that the outdoor coil is
clean, the pipe covering and insulation are not damaged, and the refrigerant
line connections are free of oil stains.
Conduct annual inspections with your installer to ensure the system is
running smoothly and efficiently by checking for refrigerant leaks, cleaning
compressor coils and scheduling regular maintenance.
