Next generation air-to-water heat pumps


With an air-to-water heat pump from CTC, you save up to 75 % on your heating costs.
The energy utilised is free and eco-friendly, and contributes to a reduction of CO₂ emissions.


CTC has two types of air-to-water heat pump.
Variable-speed heat pumps and those with a start-and-stop function.

The CTC EcoAir 600 series consists of newly-developed heat pumps with a variable-speed compressor and they adapt to the building's output needs. When more heat or hot water is required, the output of the heat pump increases. When less output is required, the pump operates at a lower speed.

The CTC EcoHeat 400 series consists of conventional heat pumps which heat the building and hot water via a compressor by means of a stop-and-start function (on/off). A conventional on/off heat pump is slightly cheaper than a variable-speed heat pump but, as a consequence, results in lower savings.
Economical and reliable: With an air-to-water heat pump from CTC, you can save up to 80 % on your heating costs. You save money from the first day and the heat pump increases the value of your house.
Convenient and flexible: A heat pump from CTC largely takes care of itself and, thanks to EnergyFlex, pools and other heat sources (such as solar heating) can easily be added.
Eco-friendly and renewable: An air-to-water heat pump converts energy in the air into heating and hot water. And because it does not require boreholes or coils in the ground, it is easy to install. The energy utilised is free and eco-friendly, and contributes to a reduction of CO₂ emissions.
