What BlueHeart Energy does
BlueHeart Energy is a Dutch deep-tech company that has developed a thermoacoustic heat pump engine marketed to HVAC OEMs. Founded in 2016 as a spinoff from TNO (Netherlands Organisation for Applied Scientific Research), the company replaces the conventional vapor compression cycle with an architecture that uses sound waves in pressurized helium to generate heating and cooling, eliminating compressors, HFC refrigerants, and flammable working gases. The 6kW base unit can be modulated between 1 and 6kW and cascaded up to 100 units for a 600kW total output, operates silently at below 40dB(A), functions across a -20°C to 80°C temperature range, carries a 20-year design life with no scheduled maintenance, and holds a PED Category 2 pressure-equipment rating.
The company's commercial strategy is to sell its thermoacoustic engine as a semi-finished component to OEM heat pump manufacturers under hardware-sales and licensing/royalty arrangements, with pricing disclosed as not public. Ecoforest (Spain) is the first OEM partner to commercialize BlueHeart-powered water-to-water heat pumps, with Eplucon acting as the Dutch channel partner; field testing at a Dutch housing corporation is underway. The engine becomes available to OEMs in Q1 2027, with first consumer-available heat pumps expected in spring 2027. Beyond HVAC OEMs, the company addresses installers, real estate owners, industrial actors, and residential and commercial end-consumers as secondary customer segments.
The company is headquartered in Heemskerk, Netherlands (relocated from Alkmaar in 2024), and has grown to over 60 employees by early 2026. Funding to date includes an October 2021 European Innovation Council investment of approximately $2.87M and an undisclosed April 2025 round co-led by US-based HVAC major Copeland and the EIC Fund. CEO and founder Michiel Hartman continues to lead the company.

Revenue model
- Thermoacoustic Engine Sales to OEMs: BlueHeart Energy manufactures and sells its thermoacoustic engine as a semi-finished product/component to OEM heat pump manufacturers. The engine replaces the traditional vapor compression circuit (compressor, evaporator, condenser) in heat pumps. Partners like Ecoforest integrate the engine into finished water-to-water heat pumps for sale to end customers.
- Licensing/Technology Transfer: BlueHeart licenses its thermoacoustic technology to OEM manufacturers who incorporate the engine into their heating and cooling products. Ecoforest is the first company to commercialize the technology, with others reportedly in development.

BlueHeart Energy product offering
Product offeringCore offering
BlueHeart Energy manufactures and sells the BlueHeart Engine, a thermoacoustic heat pump engine that uses sound waves in a pressurized helium environment to generate heating and cooling without HFC refrigerants, compressors, or direct CO2 emissions. The 6kW engine (adjustable 1-6kW, scalable up to 600kW via cascading) operates silently at <40dB(A) across a -20°C to 80°C range and is sold as a semi-finished component to OEM heat pump manufacturers such as Ecoforest for integration into finished residential, commercial, and industrial heat pump products.
Product overview
BlueHeart Energy offers a single core product: the BlueHeart Engine, a thermoacoustic heat pump engine designed as a semi-finished product for OEM manufacturers of heating and cooling applications. The engine uses sound waves in pressurized helium to deliver heating and cooling without conventional compression/evaporation cycles, refrigerants, or CO2 emissions. It is sold as a standardized, modular engine (6kW per unit) that OEMs integrate into their heat pump products for residential, commercial, and industrial markets. The company was founded in 2016 and plans commercial availability in Q1 2027.

BlueHeart Energy partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered flagship, core and foundational.
- EcoforestflagshipEcoforest is the first OEM manufacturer to integrate BlueHeart's thermoacoustic engine into their heat pump products. The Ecoforest brand, represented in the Netherlands by Eplucon, will market the first series of heat pumps equipped with BlueHeart's thermoacoustic engine. Ecoforest converts the BlueHeart engine into a water-to-water heat pump. Field testing at a housing corporation is underway with commercial production expected by end of 2026 and first deliveries in spring 2027.
- EpluconcoreEplucon represents Ecoforest brand products in the Netherlands and serves as the channel partner for BlueHeart-powered heat pumps in the Dutch market. Eplucon's Hanco Folmer confirmed positive field test results alongside BlueHeart CEO Michiel Hartman at VSK+E.
- TNO (Netherlands Organization for Applied Scientific Research)foundationalBlueHeart Energy was seeded with deep technology expertise from TNO. The company originated as a spinoff from TNO in 2016. Initial lab prototype (240W) was developed in partnership with TNO in 2015. Joint effort with TNO was required to build the first working prototype and scale capacity to 1kW in 2019. TNO partnership provided foundational thermoacoustic knowledge that enabled completion of in-house testing prototype scaled to 3kW.
