Vaillant products stand for carefully selected features and materials, rigorous testing beyond standard conditions, over 150 years of experience in heating technology, and outstanding service that lasts. Our heat pumps have undergone extensive testing in extreme environments – from freezing temperatures of -25°C to scorching heat of +48°C, and humidity levels reaching 100%. We offer a 10-year material warranty on our high-quality compressor. The result is a product that impresses today and will continue to do so tomorrow. And because true quality means long-term support, for example, we guarantee spare part availability for 15 years after end of production – ensuring peace of mind for years to come.

With the included Internet gateway myVAILLANT connect, you can conveniently track the system’s energy consumption and precisely set desired temperatures and set operation hours with no effort via our app.

Tap into nature’s steady warmth with our flexoCOMPACT exclusive ground-source heat pump. The ground stays at a constant temperature of around 10 °C all year round. With our advanced technology, the flexoCOMPACT exclusive transforms this natural resource into efficient heating, even during the chilliest winters. Its A+++ energy efficiency rating (A+++ to D) at 35 °C flow temperature means reduced heating costs and sustainable energy generation. You’re not just protecting the planet; you’re safeguarding your wallet while enjoying premium comfort every day.

To activate the cooling function, an additional module for passive cooling is required. After installation, the heat is extracted from the living spaces via the underfloor heating and released into the ground via the ground probe. This is an especially cost-efficient cooling method because the heat pump is switched off and only the pumps are running.
