Warehouse heating: options, costs and what actually works
Heating a warehouse is not really a heating problem — it is a delivery problem. The question is not how many kilowatts you buy, but how much of that heat reaches a person standing on the floor. That single distinction decides whether your winter energy bill is manageable or ruinous.
What is the cheapest way to heat a warehouse?
For occupied-zone comfort, radiant heating is usually cheapest overall because you are not paying to warm the air near the roof. Gas radiant tubes have the lowest fuel cost where gas is already on site; electric infrared has the lowest install cost and no servicing.
The problem with warehouse heating
Ceiling heights of 6–12 m mean warm air stratifies well above head height. You pay to heat thousands of cubic metres nobody occupies, and every loading-door opening dumps it outside.
Zoning strategy: Zone by work area (picking, packing, despatch) rather than heating the whole volume.
Options compared
| System | Verdict | Upfront | Running |
|---|---|---|---|
Infrared / radiant panels Warms people and surfaces directly; instant and zonal, with no wet system. | Best fit | Low | Medium |
Radiant tube heaters (gas) Also radiant, so it beats warm air; needs a gas supply, flues and annual servicing. | Viable | Medium | Low |
Gas warm-air heaters Heats air, which stratifies to the roof — most output never reaches floor level. | Poor fit | Medium | Low fuel cost, high waste |
Destratification fans alone Recovers stratified heat but cannot fix a system that heats the wrong place to begin with. | Poor fit | Low | Low |

What warehouse heating costs to install
- Single zone (packing bench area)£1,200 – £3,500
Two to six high-output radiant units on local control.
- Multi-zone unit (500–1,500 m²)£6,000 – £18,000
Zoned radiant with occupancy and time control.
- Full distribution centre£20,000+
Phased, zone-by-zone installation to avoid operational downtime.
