What HeatVentors does
HeatVentors (legal entity: HeatVentors Hőenergiatároló Kft.) is a Hungary-based private company that develops and sells intelligent thermal battery systems based on proprietary phase change material (PCM) technology, with the registered office in Mezőtúr and a branch office in Budapest. Its product portfolio spans the HeatTank series (capacities from 10 kWh to 65 kWh, max performance 20–200 kW) for compact commercial applications and the GigaBattery (1,100–1,300 kWh, 4,000 kW) for industrial-scale use, both supported by a proprietary self-learning intelligent controller that optimizes charge/discharge cycles against real-time energy prices and temperature conditions, and by a HeatBoard monitoring interface with web/API access. The technology is rooted in 10+ years of university-origin PCM research and operates across a -30°C to +120°C storage range with a non-pressurized, no-moving-parts design.
The company targets office buildings, shopping malls, hotels, data centers and telecoms, industrial thermal processes, gas engines, district heating and cooling networks, utilities, agriculture, universities, and heat-transport applications. It generates revenue through hardware sales of standard-sized thermal batteries under individually negotiated contracts (Egyedi Szerződés), accompanied by delivery, installation, and commissioning, plus recurring revenue from annual maintenance contracts (indexed to the Eurostat Producer Price Index), the HeatBoard monitoring subscription, optional EnergyReport services, and BMS integration services. Sales are direct enterprise sales, initiated via RFP or downloadable order forms on the website, with installations executed across Hungary and the broader EU market.

HeatVentors product offering
Product offeringCore offering
HeatVentors manufactures and sells Intelligent Thermal Battery hardware (the HeatTank series of 10–65 kWh units and the 1,100–1,300 kWh container-packaged GigaBattery) that store heating and cooling energy using proprietary phase change materials (PCM) and release it on demand through a proprietary self-learning controller and high-performance heat exchanger. The hardware is bundled with delivery, installation, and commissioning, and is complemented by recurring HeatBoard monitoring subscriptions, annual maintenance contracts, and EnergyReport savings documentation services sold to enterprise and institutional buyers.
Product overview
HeatVentors offers the Intelligent Thermal Battery, a modular thermal energy storage system for heating and cooling applications. The product portfolio includes the HeatTank series (HeatTank 10-1, 25-1, 25-2, 50-1, 50-2) ranging from 10 to 65 kWh capacity, and the industrial-scale GigaBattery with 1,100-1,300 kWh capacity and 4,000 kW performance. The core technology uses proprietary phase change materials (PCM) for energy storage and a proprietary high-performance heat exchanger. The system is complemented by an Intelligent Controller with self-learning optimization algorithm, the HeatBoard monitoring interface, and the optional EnergyReport service for tracking savings. The products store thermal energy when energy is economical and release it on demand, achieving 20-50% energy savings and up to 90% space/weight savings compared to conventional solutions.
