Warehouse Heating in Central Ohio: Choosing the Right System for Your Facility
Compare heating options, identify common performance problems, and plan an upgrade around your people, inventory, and daily operations.
The loading dock is cold. The packing area feels uncomfortable. Another section stays chilly even though the heaters run for hours.
For warehouse and facility managers, those complaints raise a practical question: Do you need more heating capacity, better distribution, or a different approach?
The answer starts with how your building operates.
A warehouse with frequent deliveries, tall racks, and several shifts has different needs from a lightly occupied storage building.
Choosing equipment without understanding those differences can leave the original problem unresolved.
Here is how to evaluate warehouse heating in Central Ohio—and prepare for a more productive conversation with your HVAC contractor.

Why Warehouse Heating Deserves Attention
Space heating accounted for 39% of energy consumption in U.S. warehouse and storage buildings in EIA’s 2018 Commercial Buildings Energy Consumption Survey. It was the largest end-use category. [1]
That is a national benchmark across several warehouse and storage types, not a prediction for your building.
Local weather adds context. National Weather Service data for Columbus lists January normal daily highs around 37°F and lows around 22°F. [2]
Those averages help explain seasonal conditions; they are not the outdoor design temperatures used to size heating equipment.
For managers, the takeaway is straightforward: investigate heating performance before winter exposes problems during a busy shift.
What Should You Assess Before Choosing Equipment?
Start with a walk-through and a short operating profile.
Where Do People and Products Need Heat?
Mark packing stations, loading areas, offices, storage aisles, and temperature-sensitive inventory.
Record the required conditions for each area. Employee comfort, product storage requirements, and freeze protection may call for different controls.
Ask operations and product owners to confirm their requirements before setting a single temperature for the entire building.
How Often Are Dock Doors Open?
Document which doors open, approximately how long they stay open, and when deliveries peak.
Ask your contractor to evaluate door seals, infiltration, and the relationship between exhaust and replacement air.
A useful starting record is a week of temperature complaints matched to dock activity. This helps the project team investigate operating conditions alongside equipment capacity.
Is Heat Reaching the Occupied Zone?
High ceilings create a distribution challenge. ASHRAE describes how thermal stratification can leave warmer air concentrated higher in industrial warehouses. [3]
Ask for temperature measurements at representative working and elevated locations. Review findings alongside equipment operation and rack layouts.
Destratification fans or changes to air distribution may help, but their suitability should be evaluated for the space. A fan proposal should explain the problem it addresses and how improvement will be checked.
What Infrastructure Can Be Reused?
Collect equipment model numbers, service records, utility information, and available drawings.
Confirm gas or electrical capacity, roof access, mounting constraints, and maintenance access with the project team.
These details help identify installation work that an equipment-only quote may overlook.
Which Warehouse Heating System Fits Your Facility?
The best warehouse heating system is the one that meets the facility’s documented requirements with a workable installation, control strategy, and operating cost.
Use this comparison to frame the discussion—not as a sizing guide.
System | What it does | Useful question for your contractor |
Gas-fired unit heaters | Heat air and circulate it through the space | Will the airflow reach occupied areas around the racks? |
Infrared radiant heaters | Transfer radiant heat to people and surfaces within their coverage | How do coverage, mounting height, and storage clearances affect placement? |
Packaged rooftop systems | Can combine heating, cooling, and outdoor-air functions, depending on configuration | What ductwork, roof, controls, and ventilation changes are included? |
Heat pump systems | Provide electric heating and cooling | What capacity and backup strategy are available at local winter design conditions? |
These categories overlap: a rooftop unit can use heat pump technology. The table separates heat pumps to highlight their planning questions. [4–7]
Gas-Fired Unit Heaters
Unit heaters are an option worth evaluating for open commercial and industrial spaces.
Manufacturers offer different configurations, including separated-combustion models that draw combustion air from outdoors. [4]
Ask about equipment suitability for the environment, air distribution, venting, service access, and controls.
Do not assume every gas heater is appropriate for every warehouse activity.
Infrared Radiant Heating
Infrared heaters transfer heat directly to surfaces and occupants within their coverage. ASHRAE identifies applications for both spot heating and larger areas. [5]
This makes coverage and workstation locations useful discussion points.
Storage layout matters, too.
Manufacturer instructions establish clearances to combustible materials and may require maximum stacking-height signs.
Evaluate proposed rack or inventory changes against the installed heater’s requirements. [6]
Rooftop Systems and Heat Pumps
Packaged equipment can suit projects that need coordinated heating and cooling. [7]
For a heat pump proposal, ask for cold-weather capacity, supplemental heat requirements, controls, and electrical-service implications.
Research from the National Renewable Energy Laboratory identifies outdoor temperature, defrost, sizing, and supplementary heating as important factors in rooftop heat pump performance. [7]
Compare the proposed system under your operating conditions, rather than relying on a headline efficiency rating.
Signs Your Warehouse Heating Needs Attention
Use these observations to organize an investigation.
What you notice | Information to collect |
Cold packing or picking areas | Locations, shift times, and nearby supply outlets |
Large differences between floor and upper-level temperatures | Measurements at documented heights and locations |
Complaints during deliveries | Door-open periods and affected zones |
Long runtimes or repeated equipment shutdowns | Alarm history, outdoor conditions, and maintenance records |
Rising heating costs | Energy consumption, utility rates, operating hours, and production changes |
These are prompts for evaluation, not diagnoses.
Record what changed recently: a new shift, taller racks, added exhaust, altered schedules, or a different inventory mix.
Keep the discussion specific. “The west packing area drops below our target during morning deliveries” gives a contractor more to investigate than “the warehouse is always cold.”
How to Plan a Warehouse Heating Upgrade
1. Write a One-Page Requirements Brief
Include the building layout, ceiling height, occupied zones, storage needs, delivery schedule, and future changes.
Add maintenance history and the problems you want resolved.
Use the same brief for each bidder so proposals address the same facility.
2. Request a Documented Load and Distribution Review
Ask how the proposal accounts for outdoor conditions, the building envelope, ventilation, and door activity.
Then ask how heat will reach the work areas.
Request that the contractor explain the sizing basis instead of selecting equipment from floor area alone.
Also clarify what happens during morning warm-up and peak loading activity.
3. Compare the Complete Installed Scope
Look beyond the equipment price.
Confirm responsibility for electrical or gas work, venting, roof or structural work, controls, permits, access equipment, and removal of existing units.
Review shutdown windows with operations.
Identify whether installation can be phased and how affected areas will be managed.
4. Define Handover and Performance Checks
Agree on the conditions used to evaluate the completed system.
Request control schedules, equipment documentation, commissioning records, and staff training.
Assign responsibility for checking temperatures, alarms, and operating schedules after turnover.
A documented handover gives your maintenance team a usable starting point.
How Can You Manage Heating Costs?
Start with a baseline of fuel and electricity consumption, operating hours, setpoints, and maintenance history.
Compare consumption as well as dollars: a bill can rise because of energy prices, weather, or changes in operation.
Heating degree days can help put weather differences into context. The National Weather Service explains that this measure relates outdoor temperature to heating demand; it does not account for every factor affecting energy use. [8]
Ask your contractor to evaluate controls, air distribution, and building conditions alongside equipment.
For any proposed savings, request the assumptions, calculation method, and verification plan.
Keep required product conditions and system protection part of the discussion.
Frequently Asked Questions About Warehouse Heating
What temperature should a warehouse be kept at?
There is no single setpoint appropriate for every warehouse. Establish requirements for employees, inventory, processes, and building systems, then document targets by zone.
Are radiant heaters always better than unit heaters?
No. Radiant coverage, air distribution, mounting limitations, ventilation needs, and operating patterns all affect the choice. Compare options against the same requirements.
Can the warehouse and offices use different heating systems?
Yes. Ask the design team whether separate systems or zones would better match each area’s schedule and conditions.
