GreenTherm 040S/5.40~14.95 kW-KA21761

Ventus GreenTherm 040S modulating air-to-water heat pump 5.40 - 14.95 kW

The Ventus GreenTherm 040S is a high-temperature modulating inverter air-to-water heat pump for efficient heating and cooling in homes, heating systems and light commercial HVAC applications. With a heating capacity range of 5.40 - 14.95 kW, the heat pump adjusts its output to the actual system demand.

Unlike a traditional start/stop unit, a modulating heat pump operates between minimum and maximum output. This helps keep the water temperature stable, improves comfort and supports efficient seasonal operation. The high water temperature makes this model especially suitable for renovation projects where existing pipework and radiators are retained.

Suitable for installers and HVAC applications

This heat pump is suitable for all-electric renovation, radiator systems and professional HVAC projects where reliable performance and energy efficiency are important. The unit can be combined with Nexus stainless steel buffer tanks and domestic hot water cylinders for complete heat pump installations.
