Hotta

About

Hotta is a private headquartered in Spain specializing in Energy Storage.

Hotta operates as an energy efficiency service company specializing in heat recovery systems. The core product, Smart Heater, integrates data servers that generate heat as a byproduct of computational operations. This waste heat is captured and repurposed to supply heating and hot water to residential homes and commercial workplaces. The system replaces traditional gas, heating oil, and other conventional heating fuel sources with recovered server heat. Installation is non-invasive, requiring no structural modifications and typically completed within one day. The service is fully automated and controlled via mobile app or digital thermostat, allowing users to monitor temperature, savings, and consumption data. Hotta combines Smart Heater installations with solar panels or air-source heat pumps for comprehensive energy solutions. The company offers advisory services on subsidies, tax deductions, and carbon credit eligibility. Target markets include residential properties and data centers seeking to reduce operational heating costs.
