When considering a home heating and cooling system, the choice often comes down to an inverter air conditioner or an air-to-water heat pump. Both technologies use an inverter compressor, but have different purposes and long-term efficiencies.
How does air conditioning work?
Air conditioning is excellent for cooling and heating individual rooms. Air conditioning:
- extracts heat from the air in a room and transfers it outside (or vice versa)
- is usually mounted on a wall and operates within a single zone
- can reach the desired temperature quickly
📌 However:
- achieving comfortable heating can be more expensive in cold climates, as efficiency decreases at low outdoor temperatures
- air conditioners dry the air and operate mainly locally
- are mainly suitable for cooling or supplementary heating, not as a primary heating solution throughout the winter
How does the Nikotherm CGK020V4P-B heat pump work?
The Nikotherm CGK020V4P-B heat pump is an air conditioning and heating device that uses the outside air to transfer heat into the home or vice versa. The heat pump is ideal for a complete “four seasons” system:
- Heating: extracts heat from the outside air and transfers it to a water heating circuit
- Cooling: can work in reverse, releasing heat outside
- Energy efficiency: the model has an ERP A+++ rating, which is the highest efficiency class for such devices
- COP up to ~4.4 at 7°C water temperature, which indicates that it returns about 4.4 kW of heat energy for every 1 kW of electricity consumed under standard conditions
- Suitable for heating the whole house and simultaneously provides cooling if integrated with fan coils or underfloor heating

How does a heat pump actually work?
Unlike traditional heating devices, a heat pump does not produce heat, but transfers it.
- In winter, it extracts heat from the outside air and delivers it into the home
- In summer, the process is reversed – it takes the heat outside and cools the rooms
This makes it a complete four-season air conditioning system, not just an alternative to a boiler or air conditioner.
Heating and cooling with one system
For newly built installations from Niko Therm, we most often recommend:
- underfloor heating
- fan convectors
- mixed systems according to floor and needs
Our practice shows that about 30% of customers start using the heat pump for cooling in the first year, simply because the comfort is incomparable to that of standard air conditioners.

More economical cooling than air conditioners
One of the least known advantages is that a heat pump can cool more economically than almost all air conditioners.
In cooling, the average efficiency ratio (EER) is between 5 and 6.
This means that:
- for every 1 kW of electricity you get up to 6 kW of cooling
Real-world example:
A 150 sq m house with 3 fan coils, cooled up to 8 hours a day, has an average monthly bill of around 45–55 eur.
Fan convectors – comfort without compromise
If you are looking for a feeling similar to air conditioning, but without its drawbacks, fan coils are the right solution.
They offer:
- even temperature distribution
- almost silent operation
- lack of air drying
- possibility of heating and cooling in different zones simultaneously
The combination of a heat pump and several convectors creates a complete air conditioning system for the whole year.

Mixed solutions for maximum efficiency
In the practice of Niko Term, we often build mixed systems, for example:
- underfloor heating on the first floor
- fan convectors on the second
Everything is managed by one central controller, which optimizes operation and costs.
Comfort without air conditioners on the walls
With a heat pump you get:
in winter – warm, even and economical
in the summer – cool and pleasant
without noisy indoor units
The heat pump – comfort 365 days a year
The right heat pump doesn’t just heat or cool. It works for your comfort every day of the year.

Professional project = real results
For a heat pump system to work effectively, it must be:
- properly sized
- tailored to your home and lifestyle
- implemented according to established standards
Therefore, we recommend that you trust the official representatives from Niko Therm, who work according to established quality standards and will fully assist you from the selection of a heat pump to the overall implementation of the system.
