  • The best components on the market

    In Clausius heat pumps manufacturing, we only use components from the European premium brands.

  • Integrated climate control

    Clausius heat pumps allow production of heating, cooling and domestic hot water (DHW) IN a single installation.

  • Passive cooling

    Allow passive cooling production with extremely low energy consumption and cost, technologically exceeding air source heat pumps.

  • No sound and visual impact

    Do not require noisy fans and do not generate air drafts. All their components are silent and sound insulated inside the case. In addition, as they are buried or inside the house, they do not cause any kind of visual impact.

  • Comfort for users

    Clausius ground source heat pumps are controlled with simple thermostats and do not require any user interaction, providing great comfort.

  • Clean and safe

    They do not require any type of fuel and do not generate flames or smoke, so they do not need fuel storage tanks or chimneys.

  • Reliable

    Installations with ground source heat pumps require minimal maintenance and have a long life by using a simple, proven, known and very reliable technology.

  • Energy efficiency and economic savings

    Market leading ErPA+++ rating. They provide a far more energy efficiency than traditional systems and other types of heat pumps, so the cost of heating is drastically reduced, achieving significant savings.
