Dethermina

What Dethermina does

Dethermina S.p.A. is an Italian privately-held company headquartered in Naples that designs and manufactures high-temperature heat pumps and chillers using natural refrigerant R290 (propane). Founded in 2021 by HVAC&R specialists, the company addresses the decarbonization of building heating and industrial process heat by producing water up to 80°C (A-THERM80, A-COMBO80) and up to 120°C for industrial applications (W-THERM), temperatures that conventional heat pumps cannot reach and that would otherwise require natural gas boilers or invasive hydraulic retrofits.

The product portfolio comprises four modular, scalable lines covering 30kW to 300kW capacities: A-THERM80 (reversible air-to-water heat pumps), A-COLD (industrial chillers for high-ambient cooling), A-COMBO80 (four-pipe simultaneous heating/cooling), and W-THERM (custom water-to-water industrial units). Core technology integrates reciprocating piston or screw inverter compressors, EC fans, integrated heat recovery circuits, PID-based control, LAN/BMS connectivity, and ATEX-certified safety systems for flammable refrigerants, with compliance to EN378, IEC 60529, CEI EN60335-2-40, EN60204-1, EU F-Gas Regulation 517/2014, and REACH.

Dethermina generates revenue primarily through direct B2B project-based sales of capital equipment, supplemented by embedded engineering and technical consulting services. The go-to-market is consultative and enterprise-led, targeting general contractors, design studios, installers, and facility managers across Italy and the broader European market, with flagship deployments in healthcare (large historic Roman hospital) and manufacturing (Milan-based industrial firm). Pricing is quotation-based and tailored to system size, configuration, and installation complexity, with multi-year contract cadence and no public catalogue or e-commerce channel. Distribution is exclusively direct, supported by installation partners and an Ideasw-powered remote monitoring software platform.

Revenue model

1. Heat Pump and Chiller Product Sales: Dethermina generates revenue primarily through the sale of its proprietary high-temperature heat pumps (A-THERM80), four-pipe heat pumps (A-COMBO80), industrial chillers (A-COLD), and custom industrial water-to-water heat pumps (W-THERM). Products are sold as capital equipment to commercial, industrial, and residential customers for building heating, cooling, and domestic hot water applications. Pricing is project-based and quotation-driven, reflecting the customized and modular nature of each installation.
2. Engineering and Technical Consulting Services: Dethermina provides technical consulting services including site assessment, system sizing, plant architecture design, and installation oversight. These professional services support the sale of heat pump systems and are embedded in project-based engagements with general contractors, design studios, and facility managers.

Core offering

Dethermina designs, manufactures, and sells high-temperature heat pumps and chillers using natural refrigerant R290 (propane) for building heating, cooling, and domestic hot water production. Its four product lines — A-THERM80, A-COLD, A-COMBO80, and W-THERM — deliver water up to 80°C for commercial/residential use and up to 120°C for industrial process heat, with modular and scalable configurations ranging from 30kW to 300kW. The company sells engineering-tailored systems directly to enterprise and industrial customers, with installation executed through certified general contractors and design studios.

Product overview

Dethermina is a heat pump and chiller technology company offering four distinct product lines for residential, commercial, and industrial decarbonization. The core portfolio consists of: A-THERM80 (reversible air-to-water heat pumps, 30–300kW, up to 80°C, R290), A-Cold (modular chillers for industrial cooling, 30–300kW, R290), A-COMBO80 (four-pipe simultaneous heating/cooling heat pumps, R290), and W-Therm (custom water-to-water industrial heat pumps reaching up to 120°C with natural refrigerants). All products use natural refrigerant R290 (propane) as the primary working fluid and are designed as modular, scalable systems that integrate with existing hydraulic infrastructure without requiring structural modifications.

Emerging players

• Heaten: Norwegian startup developing high-temperature industrial heat pumps for process heat applications above 100°C. Directly comparable to Dethermina's W-THERM industrial water-to-water line, with similar focus on industrial decarbonization but different geographic and segment focus.

Broad incumbents

• Bosch Thermotechnology: Major European manufacturer of heating and hot water solutions including high-temperature heat pumps (Compress 7000i AW). Overlaps with Dethermina's residential, commercial, and light-industrial heat pump segments, but with much broader product portfolio and established dealer network.
• Viessmann: German heating technology leader with Vitocal high-temperature heat pump range. Directly competes in the retrofit radiator-compatible heat pump segment that Dethermina targets, with strong European brand and installer relationships.
• Daikin: Global HVAC and heat pump leader with extensive high-temperature heat pump product lines (Daikin Altherma 3 H HT). Directly comparable to Dethermina in heat pump technology for heating and DHW, but operates at massive global scale across all HVAC categories.
• Vaillant: European heating specialist with aroTHERM plus high-temperature heat pump line. Overlaps with Dethermina's decarbonization proposition for existing buildings, with established European service network and gas-boiler replacement heritage.
• Mitsubishi Electric: Global HVAC and heat pump manufacturer with Ecodan and Zubadan high-temperature ranges targeting European residential and commercial segments. Broadly comparable technology and customer base, with vastly greater scale and R&D resources.

Direct peers

• Stiebel Eltron: German heat pump specialist with high-temperature models targeting retrofit applications. Comparable technical focus on high-temperature output for radiator systems, with stronger brand recognition in DACH markets and established installer channel.
• NIBE Energy Systems: Swedish heat pump specialist with strong European presence in residential, commercial, and industrial heat pumps. Closely comparable product positioning to Dethermina, including high-temperature models, with much larger scale and broader geographic reach.
• Robur: Italian competitor specializing in gas-fired absorption heat pumps and hybrid systems for commercial and industrial applications. Closely comparable as an Italian-headquartered decarbonization technology provider serving similar customer segments, though with absorption rather than vapor compression technology.
• Ochsner: Austrian heat pump manufacturer with deep specialization in high-temperature and industrial applications using natural refrigerants. Closely comparable technology approach (high-temperature R290/propane-based systems) and similar customer segments to Dethermina, with stronger DACH market presence.
