Ventus GreenTherm 040S high-temperature air-to-water heat pump with inverter technology, heating range 5.40 - 14.95 kW and maximum water temperature of 75°C. Suitable for all-electric renovation projects, radiator systems and professional HVAC applications.
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.
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.
