## Key takeaways

- The industrial heat pump market grows from USD 3,864.0 million in 2025 to USD 9,522.4 million by 2035 at 9.44% a year.
- Unit deliveries grow 7.2% a year, gated by energy price ratios rather than by technology.
- Closed cycle compression leads at 44%; steam generating machines grow fastest.
- Europe holds 53.4% of revenue; North America lags at 7.0% on cheap gas.
- Heat as a service is growing because industrial payback criteria reject six year projects that are otherwise sound investments.

A heat pump with a coefficient of performance of four only saves money where electricity costs less than four times gas, so this market is decided by energy policy rather than by engineering, a test that building-scale units sized in the [Ground Source Heat Pumps Market](https://www.douglasinsights.com/ground-source-heat-pumps-market/) report also face. Douglas Insights values industrial heat pump systems at USD 3.86 billion in 2025 and expects USD 9.52 billion by 2035, compounding at 9.44%. The estimate is built from the bottom up: roughly 8,400 industrial heat pump units delivered in 2025 across food and beverage, chemicals, pulp and paper, district heating and general process applications, at an average realised price of USD 460,000 per unit covering compressor package, heat exchangers, controls and integration engineering, triangulated against manufacturer disclosures, subsidy programme awards and installation records. Unit deliveries grow 7.2% a year as electrification of process heat accelerates, while realised price rises 2.1% a year as the mix shifts toward higher temperature and larger capacity machines. This study sits within our [HVAC and building energy equipment](https://www.douglasinsights.com/industry/hvac-building-energy-equipment/) coverage and follows the published [Douglas Insights methodology](https://www.douglasinsights.com/research-methodology/).

## What decides whether an industrial heat pump gets built?

The spark spread decides it, and almost nothing else. An industrial heat pump replaces a gas boiler by using electricity to move heat rather than burning fuel to create it, delivering typically three to five units of heat per unit of electricity consumed.

Whether that is worth doing depends entirely on the ratio between the electricity price and the gas price in that location, because a coefficient of performance of four only saves money if electricity costs less than four times as much as gas per unit of energy. In parts of Europe where gas prices spiked and industrial electricity is comparatively taxed, that ratio has moved in and out of favour with policy rather than with technology. In markets with cheap gas, notably North America, the arithmetic frequently fails outright without a carbon price or a subsidy, which is why deployment is concentrated where energy taxation, carbon pricing and capital grants combine to close the gap. This makes the market unusually policy dependent and geographically uneven, and it means the technology question that matters is not whether heat pumps work but how high a temperature they can reach efficiently, since every degree extends the range of processes where the economics can work at all. The exclusive chapter of this report models payback by process temperature and energy price ratio.

## What is an industrial heat pump system, and where does it stop short of building heat pumps?

An industrial heat pump system is a machine that supplies process heat to industrial users by using electricity to move heat rather than burning fuel; Douglas Insights sizes the category at USD 3.86 billion in 2025, about 8,400 units across four system types, excluding building heat pumps and cooling-only chillers.

Closed cycle compression heat pumps cover conventional vapour compression machines using refrigerants, the most widely deployed configuration, typically supplying heat up to around one hundred and sixty degrees. Mechanical vapour recompression covers open cycle systems that recompress process vapour directly, widely used in evaporation and distillation where a vapour stream already exists and offering very high efficiency. High temperature and steam generating heat pumps cover the emerging class of machines reaching above one hundred and sixty degrees and producing usable steam, using advanced refrigerants, multi stage configurations or alternative cycles. Integration, heat exchangers and controls covers the balance of plant, thermal storage where fitted, the heat recovery network on the source side and the engineering to fit the machine into an existing process; building-scale heat recovery is sized separately in our [Indoor Energy Recovery Ventilator Market](https://www.douglasinsights.com/indoor-energy-recovery-ventilator-market/) report. Domestic and commercial building heat pumps, chillers supplying cooling only, electric boilers and resistance heating, and district heating networks themselves sit outside the boundary.

## Why is process temperature the technical frontier?

Process temperature is the industrial heat pump frontier because conventional closed cycle machines supply heat up to around 160 degrees while much process heat is needed above 150 degrees as steam; the high temperature and steam generating segment, 18% of 2025 revenue at USD 695.5 million, is the fastest growing type.

Most industrial heat demand sits above what heat pumps have historically been able to supply. A large share of process heat in manufacturing is required at temperatures above one hundred and fifty degrees, much of it as steam, while conventional heat pump refrigerants and compressors have been comfortable well below that. The result has been a market limited to the lower temperature applications, drying, pasteurisation, washing, evaporation and space and water heating, which are valuable but represent a minority of the addressable heat. Pushing higher is difficult because the pressure ratio the compressor must achieve rises with the temperature lift, efficiency falls as that lift increases, and the refrigerants that perform well at high temperature must also satisfy tightening environmental rules on global warming potential and on persistent fluorinated substances, which has eliminated several candidate fluids. Manufacturers have responded with multi stage and cascade configurations, with natural refrigerants including ammonia, carbon dioxide and hydrocarbons, and with steam generating machines that have moved from demonstration into commercial supply. Each increment of achievable temperature converts a new band of process demand from theoretical to addressable, which is why the model grows the high temperature segment far faster than the market overall.

## What drives industrial heat pump demand from 8,400 units in 2025 toward 16,850 by 2035?

Industrial heat pump demand is driven by decarbonisation targets, gas price exposure, public funding and waste heat recovery, which together lift unit deliveries 7.2% a year and revenue 9.44% a year, from USD 3.86 billion in 2025 to USD 9.52 billion by 2035.

The first driver is industrial decarbonisation commitments, which underpin the 7.2% annual growth in unit deliveries from about 8,400 machines in 2025 toward roughly 16,850 by 2035. Manufacturers with emissions targets find process heat to be among their largest and most stubborn sources, and heat pumps are one of the few technologies available today rather than in a decade.

The second driver is energy cost and security. The gas price disruption in Europe made industrial users acutely aware of fuel exposure, and electrification with a high efficiency multiplier reduces both cost volatility and dependence on a single supply chain. Each unit of electricity delivers three to five units of heat, which is why Europe, the region most exposed to the gas price disruption, holds 53.4% of 2025 industrial heat pump revenue.

The third driver is public funding. Capital grants, tax credits and industrial decarbonisation programmes cover a substantial share of project cost in several markets, and deployment tracks those programmes closely because unsubsidised payback is often too long for industrial investment criteria. A programme covering a third or more of capital decides whether a project clears the two to four year payback that industrial buyers typically demand.

The fourth driver is waste heat availability. Many processes reject large quantities of low grade heat that is currently discarded, and a heat pump upgrading that stream to useful temperature has far better economics than one drawing from ambient conditions. Mechanical vapour recompression, which upgrades a vapour stream that already exists, holds 24% of 2025 revenue, USD 927.4 million, and has the shortest payback of any configuration.

## What holds back industrial heat pumps where electricity costs more than four times gas?

Energy price ratios hold back industrial heat pumps most: a machine with a coefficient of performance of four only saves money where electricity costs less than four times gas, which is why North America, with cheap natural gas, grows 7.0% a year against 9.44% for the market as a whole.

Three restraints are modelled. Energy price ratios are the first and most fundamental: where electricity is expensive relative to gas, often because of levies and network charges loaded onto power rather than fuel, the operating economics fail regardless of equipment performance, and no amount of capital subsidy fixes a negative running cost comparison.

Integration complexity is the second industrial heat pump restraint, and on a difficult retrofit integration can double the project cost; separately contracted integration, heat exchangers and controls already account for 14% of 2025 revenue, USD 540.9 million. Retrofitting a heat pump into a working process requires matching source and sink temperatures, modifying the heat network, finding space and taking a production outage, and this engineering frequently costs more than the machine, which surprises buyers and stalls projects at feasibility stage.

Refrigerant regulation is the third industrial heat pump restraint: restrictions on fluorinated gases have removed working fluids and created uncertainty about the long term availability of others, pushing designers toward natural refrigerants that carry their own flammability, toxicity or pressure constraints. If these restraints bind together, as in the unfavourable-spread scenario, unit growth slows to 3.8% a year and the market lands near USD 6.04 billion in 2035 rather than USD 9.52 billion.

## Which industrial heat pump segment carries the value, closed cycle at 44% or steam generating machines?

Closed cycle compression heat pumps lead with 44% of 2025 revenue, USD 1.70 billion, the mature and most widely deployed configuration serving the low and medium temperature applications where the economics already work.

Mechanical vapour recompression holds 24%, USD 927.4 million, concentrated in evaporation, distillation and drying, where the very high effective efficiency of recompressing an existing vapour stream makes payback shortest of any configuration. High temperature and steam generating heat pumps account for 18%, USD 695.5 million, the smallest established group and by far the fastest growing, as machines capable of supplying steam move from pilot installations into commercial orders. Integration, heat exchangers and controls contribute 14%, USD 540.9 million as separately contracted scope, though the true integration cost borne by end users is considerably higher and is analysed separately. Each type is modelled through 2035 by temperature band and region.

| Industrial heat pump system type | Share of 2025 revenue | 2025 revenue |
| --- | --- | --- |
| Closed cycle compression | 44% | USD 1.70 billion |
| Mechanical vapour recompression | 24% | USD 927.4 million |
| High temperature and steam generating | 18% | USD 695.5 million |
| Integration, heat exchangers and controls | 14% | USD 540.9 million |
| Total | 100% | USD 3.86 billion |

## Where are industrial heat pumps installed, from Europe's 53.4% share to Asia Pacific's 11.2% growth?

Europe leads the industrial heat pump market with 53.4% of 2025 revenue, USD 2.06 billion, growing 9.4% a year, followed by Asia Pacific at 24.6% and North America at 16%.

Europe is by a wide margin the most active market because carbon pricing, national industrial decarbonisation funds and high gas price exposure combine to make the case, with the Netherlands, Germany, the Nordic countries, France and Austria most active. Asia Pacific holds 24.6%, USD 950.5 million, and grows fastest at 11.2%, led by Japan, where manufacturers have supplied industrial heat pumps for decades and the technology is unusually mature, alongside China and South Korea. North America holds 16%, USD 618.2 million, at 7.0%, the slowest of the major regions because abundant cheap natural gas undermines operating economics outside specific states with high gas prices or strong incentives. The Middle East contributes USD 115.9 million at 8.2%, Latin America USD 77.3 million at 8.6% and Africa USD 38.6 million at 7.8%. Six regional models sum to the global figure, with country tables in the Excel model.

| Region | 2025 industrial heat pump revenue | 2035 revenue | CAGR 2026-2035 |
| --- | --- | --- | --- |
| Europe | USD 2.06 billion | USD 5.06 billion | 9.37% |
| Asia Pacific | USD 950.5 million | USD 2.74 billion | 11.17% |
| North America | USD 618.2 million | USD 1.22 billion | 6.99% |
| Middle East | USD 115.9 million | USD 254.1 million | 8.17% |
| Latin America | USD 77.3 million | USD 176.0 million | 8.58% |
| Africa | USD 38.6 million | USD 81.7 million | 7.79% |
| Global | USD 3.86 billion | USD 9.52 billion | 9.44% |

## Who supplies industrial heat pumps?

Eleven equipment makers are named here as suppliers of industrial heat pumps, led by Japanese manufacturers whose home market has bought the machines for decades and by European groups serving Europe's 53.4% share of 2025 revenue.

Japanese manufacturers hold unusually strong positions given the maturity of their domestic market, with Mayekawa and Kobe Steel supplying high temperature and steam generating machines and Mitsubishi Heavy Industries active across configurations. European suppliers include GEA, strong in ammonia systems and food and beverage applications, Johnson Controls and its industrial refrigeration brands, Siemens Energy with large capacity machines, Spilling and Piller in compression and recompression, and Olvondo Technology with high temperature systems. Carrier and Danfoss supply components and complete systems, and Danfoss in particular holds a significant position in the compressors and heat exchangers that other manufacturers integrate. Engineering contractors and industrial refrigeration specialists perform much of the integration work and frequently own the customer relationship. The competitive chapter profiles temperature capability, refrigerant strategy, capacity range, reference installations by industry, and whether each participant sells equipment, complete systems or heat as a service.

## How much does an industrial heat pump cost, from USD 460,000 per unit to multi-million steam installations?

Realised equipment price averages USD 460,000 per unit in 2025, spanning from roughly a hundred thousand for a small closed cycle machine serving a modest process load to several million for a large steam generating installation or a district heating scale unit.

The figure that actually governs investment decisions is installed cost per megawatt of thermal output, which typically runs well above equipment cost once integration, electrical supply upgrade, heat network modification and commissioning are included, and integration can double the project cost on a difficult retrofit. Grant funding materially distorts effective pricing in subsidised markets, where a programme covering a third or more of capital changes which projects clear investment thresholds. Heat as a service arrangements, in which a supplier finances and operates the installation and sells heat at an agreed price, have appeared in response to industrial reluctance to commit capital to energy infrastructure, and they shift the economic risk onto the party best able to model it. The pricing chapter publishes equipment and installed cost bands by capacity, temperature band and configuration.

## Which scenario takes industrial heat pumps from USD 6.04 billion to USD 14.7 billion by 2035?

The industrial heat pump base case carries 7.2% unit growth and 2.1% price growth for a 9.44% revenue CAGR and USD 9.52 billion in 2035, inside a scenario range of USD 6.04 billion to more than USD 14.7 billion.

The unfavourable-spread scenario, in which electricity remains expensive relative to gas and subsidy programmes are scaled back, sets the legs at 3.8% and 1.0%, landing near USD 6.04 billion. The high-temperature-breakthrough scenario, in which steam generating machines reach commercial maturity and carbon pricing strengthens, sets them at 10.6% and 3.8%, carrying the market past USD 14.7 billion. Each 1-point change in unit growth moves the 2035 figure by roughly USD 870 million.

## Which refrigerant rules and pressure equipment regulations shape industrial heat pump design?

Three layers of rules shape industrial heat pumps: fluorinated gas phase-downs that decide which refrigerants remain, pressure equipment safety codes, and the carbon pricing and subsidy policy that decides whether projects pay, with grants covering a third or more of capital in subsidised markets.

Refrigerant regulation comes first and is reshaping product design: restrictions on fluorinated greenhouse gases with phase down schedules and quota systems, together with emerging restrictions on persistent fluorinated substances, determine which working fluids remain available and have pushed the industry toward natural refrigerants faster than performance alone would have. Pressure equipment and safety standards are second: heat pump systems are pressure equipment subject to design, inspection and certification requirements, and machines using ammonia or hydrocarbons carry additional toxicity and flammability obligations affecting plant room design, ventilation and separation. Energy and emissions policy is third and supplies the demand: carbon pricing, industrial emissions rules, energy efficiency obligations and the design of subsidy programmes determine project economics directly. The regulatory chapter maps refrigerant timetables and subsidy programme terms by market.

## What does heat as a service change?

The obstacle for industrial heat pumps has rarely been that the technology does not work; it is that industrial companies do not want to own energy infrastructure. A food manufacturer evaluates a heat pump against investment criteria written for production equipment, typically demanding payback in two to four years, and a project with a six year payback fails that test even when its lifetime return is excellent.

The emissions case can be compelling and the project still fail that test. Heat as a service sidesteps that entirely: a specialist finances, installs, owns and operates the heat pump and sells the manufacturer heat at a contracted price, usually indexed to energy costs, so the manufacturer replaces a capital decision with an operating contract and keeps its balance sheet for production assets. The party taking the risk is better placed to hold it, because it can model the energy spread across a portfolio of sites rather than betting a single plant's budget on it, and it earns a return on capital that industrial investment criteria would have rejected. The constraint is that these arrangements require long contract terms, and a manufacturer uncertain whether a site will still be operating in fifteen years hesitates to sign. The model treats service structures as a growing share of installations rather than as a separate market.

## Douglas Exclusive: the payback economics model

The industrial heat pump payback model estimates, by process temperature band, configuration and region, the achievable coefficient of performance, the electricity to gas price ratio required for operating cost parity, equipment and integration capital per megawatt thermal, available subsidy by programme, carbon price contribution, and resulting simple payback and internal rate of return, converting industrial heat demand by temperature into addressable unit deployment by region. Licence holders receive it as a maintained tab in the Excel model. It is a Douglas Insights model, not an official register: it is built from about 8,400 units of 2025 deliveries across three temperature bands, four system types, five end industries and six regions, each screened against local electricity to gas price ratios and subsidy availability.

## Methodology and receipts

The model is built bottom-up from units: industrial process heat demand by temperature band, sector and region, the share technically addressable by each heat pump configuration, economic screening against local energy price ratios and subsidy availability, historical unit deliveries and realised prices from manufacturer and programme disclosures, and integration cost ratios, with building heat pumps, cooling only chillers, electric boilers and district heating networks excluded. Every figure carries a numbered source and a confidence grade in the fact sheet above, and the working model ships with every licence. The headline receipt is about 8,400 units at a USD 460,000 average realised price, giving USD 3.86 billion in 2025, with six regional models, four system types, three temperature bands and five end industries reconciled to that total. The next scheduled review of this study is September 2027. Automated checks test every figure on this page against the model and AI tools assist with drafting; the Douglas Insights research desk chooses the sources, builds the model and approves publication, as set out in our [editorial standards](https://www.douglasinsights.com/editorial-standards/).
