Premium W040S / 3.80~12.50kW-KA20249
Ventus Premium W040S modulating air-to-water heat pump 3.80 - 12.50 kW
The Ventus Premium W040S is a 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 3.80 - 12.50 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 monoblock design supports straightforward installation by qualified installers without F-gas work on the refrigeration circuit.
Suitable for installers and HVAC applications
This heat pump is suitable for central heating systems, low-temperature heating and underfloor heating 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.
