CTC heat pump models: how to choose the most suitable in 2026?

The most powerful CTC heat pump models will not always be the most suitable for your house. The choice depends on the heat loss of the building and the heating system, so the name of the model or the higher capacity itself does not make any difference. Technical terms and indicators are not always easy to compare, especially if the equipment is compatible with the existing heating and everyday needs of the house.

This article will explore the CTC EcoAir models and find out which data should be checked before decision making: power, seasonal efficiency or SCOP, refrigerant, sound performance and operating temperature. Let's see how these parameters relate to the heating load and heating system of the building and why the choice should not be based on just one figure.commodus specialists can help to assess the requirements of the home and heating system, as well as link the choice of the equipment to design, installation and maintenance.

CTC heat pump models: which EcoAir families compare?

CTC EcoAir is an air-water heat pump model family that transfers ambient air heat to the water heating system. If you want to refresh basic knowledge about technology, look at the explanation about heat pump operating principle. When comparing CTC heat pump models, start with two families of Kommodus: EcoAir 600M and EcoAir 700M. The series designation helps to find a model in the catalogue, but does not in itself say which one will suit your building.

How to navigate in EcoAir 600M and 700M names?

The product range of Commodus features the models of the EcoAir 600M series 610M, 614M and 622M, as well as the models of the EcoAir 700M series 708M, 712M and 720M. Take this list as a starting point, not as a guarantee that each model will be available at the time you make your choice. CTC air-water heat pumps supply and current technical data of the model in question.

The name of the series and the model number help to find the equipment in the catalogue, but do not replace the calculation of the building's capacity. Do not choose the series just because its name seems younger or the model sounds more powerful. First, you find out the heating needs of the house and check the parameters of the particular installation.

What does the model name reveal about your house?

The model number does not tell how much heat the building loses, what its heating system is and at what temperature it should operate. Before choosing to collect information about:

• the building area, insulation and heating needs;
• existing heating systems such as radiators or warm floors;
• hot water consumption and heating management solution.

When these requirements are evaluated, model parameters can be compared and the most suitable options can be identified. Commodus advice and design helps to link the choice of equipment to the needs of the home and heating system.

CTC EcoAir 600M and 700M: which parameters help to compare?

CTC heat pump models are compared by several parameters, not only by capacity. The table below summarises the available information on EcoAir 600M and 700M families. It helps to get to know the models, but does not replace the assessment of the heating needs of the particular house.

• Series and models: EcoAir 600M: 610M, 614M, 622M; Power ranges: 610M: 2,5-10 kW; 614M: 2,5-14 kW; 622M: 4.5-22 kW; SCOP and class: Up to 6,19; A++; Cold generator: R407C; Sound and function: Up to 31 dB (A) at 5 m. Heating and hot water; EnergyFlex allows to connect other heat sources.

Capacity describes the range of heat output under certain conditions, but does not in itself say which model will suit a particular building. SCOP The CTC heat pump models are therefore assessed on the basis of both catalogue data and their compliance with home needs.

How to evaluate noise and functions?

For example, the 600M series is mentioned at 31 dB (A) at five meters. This indicator cannot be directly compared to 700M data if the measurement conditions are different. The control application and additional functions can be convenient, but they assess whether they are necessary for your system. LIAA Information on Smart Energy Solutions.

Before selecting test of the current parameters and availability of each model CTC Product InformationIf necessary, discuss with the Commodus specialist how the specific data meets the heating requirements of your home.

How to choose CTC heat pump model for your heating system?

The selection of the model is based on information about the house and heating system rather than on the highest capacity indicated in the catalogue. The CTC heat pump models are assessed by how well their parameters correspond to the calculated heat load of the building, the existing heat return devices and the hot water needs. The more accurate the information will be prepared, the more reasonable the specialist will be able to evaluate the appropriate options.

What data should be prepared for the model?

Before consulting, collects what is already known about the building and its heating.

• building space, insulation and information on windows, roof and exterior walls;
• heating consumption, if known, and information on the calculated heat load;
• the type of existing boiler and the construction of the heating system;
• information whether the premises are heated by radiators, heated floors or both;
• hot water use needs.

Also write down the temperature of the heating system if you can find out. If you can't, ask the specialist what information will be needed for evaluation. Recommendations of the Consumer Rights Protection Centre also stresses the importance of assessing the building and technical characteristics.

Does higher capacity always mean better choice?

The catalogue's capacity indicator alone does not reveal the capacity needed for your home. The suitability is determined by calculation and compatibility with the existing system, including its operating temperatures and heat return devices. Choose a larger model for safety is not the same as choosing the equipment according to the project. The specialist can help to assess these conditions and compare them with the data of the specific heat pump.
