Commercial and Industrial Heat Pumps
Which heat pump technology fits your facility depends almost entirely on whether you need process steam. Get that answer right before you talk to any vendor.
Who this is for
- ■Plant managers and facility directors at manufacturers evaluating electrification of heating loads
- ■Operations executives at hospitals, K-12 districts, and large commercial facilities weighing HVAC replacement
- ■Indiana C&I operators spending five figures or more per month on electricity
- ■Anyone getting an air-source pitch for what is actually an industrial steam problem
Should our facility invest in air-source, ground-source, or industrial waste-heat pumps to electrify heating and cooling?
Process heat accounts for up to 51% of on-site industrial energy use in the United States. Electricity currently supplies less than 5% of that demand. The rest is natural gas and other fossil fuels. If you evaluate heat pump technology only for space conditioning, you leave the majority of your facility's thermal load untouched, and you leave the majority of your future fuel-cost exposure untouched with it.

- 02 The mechanism Why COP exceeds one hundred percent
Heat pumps do not generate heat. They move it. That is why the Coefficient of Performance, or COP, can exceed one. Conventional heating systems land between 70% and 90% effective efficiency. Heat pumps operate at 300% to 400%. For every unit of electricity consumed, a heat pump delivers three to four units of heat, because the electricity is used for compression, not to create heat.
COP by heating technologyA heat pump's fuel-input economics are fundamentally different from any combustion or resistance system. For comparison, fossil-fuel boilers land at a COP of 0.83 and electric boilers at 0.99. Both need significantly more energy input to produce the same amount of process steam. Con Edison's own material puts it in operator terms: heat pumps run up to 3 x more efficient than oil-fueled systems. Commercially available industrial heat pumps deliver process heat up to 160°C (320°F), which covers a substantial portion of industrial thermal loads.
The technology field is not one thing. It is three distinct categories, each with a use case where it is the right answer and applications where it does not belong.
ASHPAir-source
Extracts heat from outdoor air. Fits commercial replacements, light industrial, K-12, and VRF zone-control applications. Efficiency degrades in extreme cold. Falls short at industrial steam temperatures and pressures.GSHPGround-source

If your facility's heating and cooling loads are asymmetric, the borefield can gradually overheat or overcool, and system performance declines over years. Data centers are the clear case: they are almost pure cooling loads, so they continuously reject heat into the ground, which drives ground temperatures up year over year and erodes heat pump efficiency. Hospitals often have similar asymmetries. This is a design-and-planning question that needs to be answered over a 20 years to 30 years horizon, not just at commissioning.
Hybrid vs. all-or-nothingFull replacement is rarely the only path
Operators rarely need to frame this as boiler-in or boiler-out. A parallel deployment, with a heat pump handling baseload and the existing boiler handling peaks and providing redundancy, is often the more financeable path. It adds control-integration complexity, but it removes the all-or-nothing capital risk. Hybrid steam-generating heat pump systems can be located up to 0.5 miles from the facility they serve, which opens siting options that a boiler-room replacement never has.
Myth Reality Heat pump project means ripping out the boiler. Hybrid parallel integration lets the heat pump handle baseload while the boiler handles peaks and redundancy. GSHP performance is set at commissioning. Borefield thermal balance shifts over decades. Asymmetric loads degrade performance if not planned for. Industrial heat pumps are experimental. MVR technology has been reliably used in dairy evaporators for decades and deployed at full industrial scale in Europe and Asia. Adoption is slow because the tech does not work. The adoption gap is upfront capital, integration complexity, and the inertia of existing steam systems. Not technology. - 04 The design risk Borefield thermal balance, and hybrid integrationBorefield thermal balance

The adoption gap is upfront capital, integration complexity, and the inertia of existing steam systems. Not technology. The heat pump decision is less complicated than it is made to sound. If your load is space conditioning and you do not need industrial steam, air-source or ground-source makes sense depending on your climate and capital. If you have a real process steam load and you also have recoverable waste heat, which most manufacturers do, the MVR category deserves a serious look. The barriers to adoption are financial and logistical, not technical.
- 1 Classify your primary heating load: process steam, low-temperature process heat, or space conditioning. This single answer narrows the technology field before any pitch begins.
- 2 Quantify your recoverable waste heat. If drying, refrigeration, process cooling, or separations are running, the waste stream is likely already there.
- 3 If evaluating GSHP, ask for a borefield thermal balance model over a twenty to thirty year horizon, not a commissioning snapshot.
- 4 For any project, ask whether hybrid parallel integration is on the table before accepting full replacement as the only option.
- 5 Model outcomes on location-specific electricity pricing and location-specific grid conditions, not national averages.
Payback ranges by heat pump categoryPayback varies by an order of magnitude across categories. Category selection matters more than vendor selection. If you caught Episode 19 on CHP systems, you know how combustion-based generation addresses heating loads. Heat pumps take the opposing approach: moving heat electrically rather than burning fuel to create it. Both can be the right answer depending on your load profile and fuel economics. And once your heating load is on electricity, Episode 2 on Time-of-Use rates becomes far more relevant to what you actually pay each month.

When a heat pump investment is worth acting on, and when it is not
✓ Act on it- You have a real process steam load and recoverable waste heat streams from drying, refrigeration, separations, or process cooling.
- You are replacing central HVAC equipment at end of life and the capital is already budgeted.
- Your facility has heating and cooling load symmetry that makes borefield thermal balance manageable.
- You can access referendum funding, federal incentives, or utility rebates that meaningfully reduce upfront cost.
- Hybrid parallel integration is available so you do not have to accept full boiler replacement risk.
✗ Slow down- You are being pitched air-source technology for an industrial steam application. The temperature and pressure do not fit.
- Nobody has modeled borefield thermal balance for your load ratio over a multi-decade horizon.
- The savings case rests on national-average grid conditions rather than your specific location.
- The proposal assumes full boiler replacement and no parallel or hybrid option has been priced.
- Your operation cannot tolerate the downtime a full steam system replacement would require.

Questions for your morning huddle- Is our primary heating requirement process steam, or is it space conditioning? What percentage of our thermal load is each?
- If we operate a ground-source system or are evaluating one, has borefield thermal balance been engineered for our heating-to-cooling load ratio over a twenty to thirty year horizon?
- If we have industrial thermal processes running, has anyone actually quantified how much waste heat we release and what it would cost to capture and upgrade it?
- Has hybrid parallel integration been evaluated as an alternative to full boiler replacement, and if not, why not?

It depends on climate and capital. Air-source has the lowest upfront cost, minimal space needs, and works well for commercial replacements and light industrial, but performance degrades in extreme cold. Ground-source delivers up to 50% better annual efficiency and holds performance in cold climates, but carries the highest upfront cost, needs borefield space, and requires long-term thermal balance planning. Neither efficiently generates industrial steam.
can heat pumps replace an industrial boiler for process steam
Air-source, ground-source, and water-source heat pumps generally cannot, because ambient-temperature sources produce low efficiencies at industrial steam temperatures and pressures. Mechanical vapor recompression steam-generating heat pumps can, using electricity to upgrade low-grade waste heat into boiler-quality steam. MVR SGHPs have COPs from 2.1 to over 8 and have been reliably used in dairy evaporators for decades.
what is COP for a heat pump and how does it compare to a boiler
COP is the Coefficient of Performance: units of heat delivered per unit of electricity consumed. Heat pumps typically hit COPs of 3 to 4, which is 300% to 400% effective efficiency. Fossil-fuel boilers have a COP of 0.83 and electric boilers 0.99. Heat pumps move heat rather than create it, which is why COPs above one are physically possible.

how long is the payback on a commercial or industrial heat pump
It varies by category by an order of magnitude. Ground-source heat pumps typically pay back in 7 years to 15 years. Industrial heat pumps that leverage waste heat can pay back in under 2 years in some applications, per ACEEE research, though that is the upper end of the opportunity rather than the median. Air-source generally has the shortest payback among space-conditioning options.
what is borefield thermal balance and why does it matter for geothermal
A geothermal borefield acts as a thermal battery. If a facility's heating and cooling loads are asymmetric, the borefield gradually overheats or overcools, and system performance declines over years. Data centers, which are nearly pure cooling loads, are the clear risk case, and hospitals often have similar asymmetries. Designers need to model thermal balance over a 20 years to 30 years horizon, not just at commissioning.
do I have to fully replace my boiler to install an industrial heat pump
No. Hybrid parallel integration lets a heat pump handle baseload while the existing boiler handles peaks and provides redundancy. This removes the all-or-nothing capital risk of full replacement and reduces downtime exposure. Some hybrid steam-generating heat pump systems can be located up to 0.5 miles from the facility they serve, which opens siting options a boiler-room replacement never has.

- Coefficient of Performance. Units of useful heat delivered per unit of electricity consumed. A COP above one means the system moves more heat than the electricity it consumes.
- ASHP
- Air-source heat pump. Extracts heat from outdoor air and moves it into or out of a building. Common in commercial and light industrial settings.
- GSHP
- Ground-source heat pump. Also called geothermal. Uses the earth's relatively stable temperature as a heat exchange medium via a borefield.
- WSHP
- Water-source heat pump. Extracts heat from a lake, river, or reservoir. Faces the same temperature-limit constraint as ASHP for industrial steam generation.
- MVR
- Mechanical vapor recompression. Uses electricity to compress low-temperature vapor into high-temperature, high-pressure steam. Used in dairy evaporators for decades.
- SGHP
- Steam-generating heat pump. A heat pump configured to produce boiler-quality steam at industry-required temperatures and pressures, typically using waste heat.
- VRF
- Variable Refrigerant Flow. An ASHP configuration that circulates refrigerant to multiple indoor units for simultaneous heating and cooling in different zones.
- Borefield
- The array of vertical or horizontal ground loops in a GSHP system that exchanges heat with the earth.
- Process heat
- Thermal energy consumed by industrial processes such as drying, separations, refrigeration, and steam generation. Distinct from space heating.
