CTC EcoAir 614M Air/Water Heat Pump

Description

CTC EcoAir 614M is a powerful, highly efficient and speed-controlled air/water heat pump developed to provide optimal comfort and exceptional operating economy in the Nordic climate. Equipped with a modulating inverter-controlled scroll compressor, the unit continuously adapts the output between 2.5 and 14 kW to the property's exact energy needs. By reducing the number of start and stop cycles, wear on mechanical components is minimized while optimizing electricity consumption, which reduces annual heating costs by up to 80%.

The heat pump efficiently extracts the renewable energy in the outdoor air and transfers it to both the heating system and domestic hot water without the need for boreholes or ground loops. With a design adapted to harsh winter conditions, the CTC EcoAir 614M delivers reliable heating down to minus 22 degrees and produces supply temperatures of up to 65 degrees. The sound-absorbed compressor and aerodynamically shaped fan also guarantee very quiet and discreet operation.

Reliable operation and functional design

To prevent ice formation and ensure uninterrupted heat delivery during the winter, the outdoor unit has automatic demand-controlled defrosting. Condensation water is safely drained through a factory-fitted condensation tray with built-in heater, eliminating the risk of frost and ice forming under the unit. The durable casing made of galvanized and painted steel sheet protects the components against external weather influences year after year.

Smooth control and docking options

To achieve maximum efficiency and easy monitoring, the CTC EcoAir 614M is installed with compatible modules:

• CTC EcoZenith i350 / i360: Indoor modules with integrated water heater and user-friendly color touch screen that makes controlling and adjusting temperatures easy.
• CTC EcoZenith i555 Pro: All-in-one tank for properties with particularly extensive hot water needs.
• CTC EcoLogic: Advanced control module for flexible operation with existing boilers, storage tanks, solar panels or pool systems in up to four separate heating circuits.

Warranty and security

Please note that the manufacturer’s full warranty is not applicable for units bought in Sweden and installed outside Sweden. Velltra assures that all CTC products that are marketed and sold by us are manufactured in Sweden and contain components of the highest quality that are adapted for the Nordic market, i.e. No CTC products are imported that may have lower quality requirements that are adapted for other markets.

In addition to this, a 3-year product warranty and 3-year security insurance are included, which means 6 years of security for private individuals and 5 years of security for legal entities. After this period, Arctic offers the opportunity to extend the insurance annually up to 16 years for air/water heat pumps.
