Cold spots in warehouses are more than a comfort issue. They affect staff productivity, equipment performance, and in some sectors, the integrity of stored goods. Large open floor plans, high ceilings, loading bay doors, and poorly sealed structures all conspire to create pockets of cold air that standard heating systems struggle to reach consistently.
For warehouse managers and commercial property owners across the North East and Northumberland, where winters are long and temperatures drop reliably from October through to March, finding the right heating solution is a practical necessity. The good news is that the causes of warehouse cold spots are well understood, and there are proven solutions for almost every building type and budget.
This guide covers eight heating solutions for warehouse cold spots, from Gas Safe registered engineering services that address root causes, to supplementary electric and radiant options suited to specific zones. Each is assessed on effectiveness, running costs, suitability for large commercial spaces, and how it integrates with existing systems.
Best for: Warehouses where cold spots may stem from an underperforming or unbalanced existing heating system.
Commercial Boiler Solutions is a Gas Safe registered commercial heating specialist serving warehouses and industrial premises across the North East and Northumberland, including Newcastle, Sunderland, Middlesbrough, Tyneside, Wearside, Teesside, and Northumberland.
Before investing in supplementary heating equipment, it is worth establishing whether your existing system is actually performing as it should. Many warehouse cold spots are symptoms of a poorly balanced wet heating system, a boiler operating below its rated output, or thermostatic controls that are no longer functioning correctly. A professional assessment can identify these issues at source, often delivering significant improvements without the capital cost of new equipment.
Commercial Boiler Solutions carries out system balancing, boiler output assessments, and full annual inspections on commercial premises. For facilities managers across the North East, having a local Gas Safe registered contractor available for both planned maintenance and emergency callouts provides continuity that matters when temperatures drop in January and heating failures become urgent.
Gas Safe Registered Engineers: All gas work is legally compliant under the Gas Safety (Installation and Use) Regulations 1998, with registration verifiable on the Gas Safe Register.
System Balancing and Boiler Output Assessment: Identifies and resolves the root causes of uneven heat distribution rather than masking them with supplementary heating.
Annual Inspections and Maintenance Contracts: Structured service agreements ensure ongoing performance and compliance for commercial premises.
Emergency Callout Service: Available across Newcastle, Sunderland, Middlesbrough, Tyneside, Wearside, Teesside, and Northumberland, with same-day response available.
5-Star Rated Service: Consistently reviewed for prompt, professional response — particularly relevant for facilities where heating downtime is operationally disruptive.
Commercial property owners and facilities managers in the North East and Northumberland who want to resolve cold spots efficiently and cost-effectively. Particularly valuable for sites with older or poorly maintained heating systems, where the problem may be underperformance rather than a fundamental gap in heating provision.
Contact for assessment and contract pricing. Costs vary by site size, system complexity, and service requirements. An initial assessment is the logical starting point before committing to any capital expenditure on new heating equipment.
Best for: High-bay warehouses with ceiling heights of five metres and above where warm air stratification is a persistent problem.
Schwank is one of the established names in gas radiant tube heating for industrial and commercial buildings, offering ceiling-mounted systems designed specifically for large, high-volume spaces.
Unlike convective heating systems that warm the air, radiant tube heaters emit infrared radiation that warms surfaces and occupants directly. In a high-bay warehouse where warm air naturally rises to roof level, this is a significant practical advantage: the heat reaches where it is needed rather than pooling overhead.
They are particularly well suited to buildings with ceiling heights of five to fifteen metres or more, and can be directed to target specific cold zones along loading bays, at workstations, or in areas where structural cold bridges create persistent problems. Running costs for continuous use are generally lower than electric alternatives, making them a practical primary heating solution rather than a supplementary one.
Effective in High-Bay Environments: Designed for buildings with ceiling heights from five metres upwards, where convective systems underperform.
Directional Heating: Systems can be positioned and angled to target specific cold zones within the warehouse floor plan.
Lower Running Costs for Continuous Use: Gas-fired operation is generally more cost-effective than electric heating for sustained, high-output applications.
Gas Safe Registered Installation Required: All installation and servicing must be carried out by a Gas Safe registered engineer — this is a legal requirement, not optional.
Annual Servicing Required: Under the Gas Safety (Installation and Use) Regulations 1998, gas appliances in commercial premises must be serviced annually by a registered engineer.
Warehouses and industrial units with high ceilings where thermal stratification is the primary cause of cold spots. Also well suited to buildings where the working environment is draughty or where doors are frequently opened, as radiant heat is less affected by air movement than convective systems.
Supply and installation costs vary considerably depending on system size, ceiling height, and the number of zones required. Obtain quotes from Gas Safe registered contractors with commercial heating experience.
Best for: Medium-height warehouses needing fast heat-up times and zone-specific warm air delivery.
Reznor produces gas-fired cabinet heaters widely specified for commercial and industrial premises across the UK, available in ducted and non-ducted configurations to suit different building layouts.
Gas warm air unit heaters respond quickly, making them particularly effective for shift-based operations where a warehouse may be unoccupied overnight and needs to reach working temperature rapidly before staff arrive. They can be positioned and directed to push warm air into persistent cold zones, and ducted versions allow heat to be channelled to specific areas of the floor plan.
They are most effective in warehouses up to approximately six to eight metres in ceiling height. In taller buildings, warm air delivery can still be subject to stratification, which is where destratification fans (covered below) become a useful complement.
Fast Heat-Up Times: Delivers rapid warm air output, well suited to intermittent or shift-pattern use where quick temperature recovery is a priority.
Directional and Ducted Options: Non-ducted units can be aimed at cold zones; ducted versions distribute heat to specific areas via ductwork.
Range of Output Capacities: Available in configurations to suit warehouses of varying sizes and heating demands.
Gas Safe Registered Installation and Servicing Required: Legal requirement under the Gas Safety (Installation and Use) Regulations 1998 for all gas appliance work in commercial premises.
Zone-Specific Application: Can supplement an existing heating system by targeting areas that the primary system consistently fails to reach.
Warehouses with medium ceiling heights, particularly those operating on shift patterns where fast heat recovery is valued. Also useful as a supplementary solution in specific cold zones within a larger facility.
Unit costs and installation vary by output rating, configuration, and whether ducting is required. Consult a Gas Safe registered commercial heating engineer for specification and pricing relevant to your site.
Best for: Warehouses with ceilings above four metres where warm air pools at roof level, leaving floor-level areas cold.
Big Ass Fans is a well-known manufacturer of large-diameter, low-speed ceiling fans designed for industrial and commercial buildings, where thermal stratification is a recognised source of energy waste and worker discomfort.
Destratification fans do not generate heat themselves. Instead, they slowly push the warm air that accumulates at ceiling level back down to the occupied zone, redistributing heat that is already being paid for. In a high-bay warehouse, the temperature difference between floor level and ceiling level can be substantial, and addressing this through fan-assisted mixing can meaningfully reduce cold spots without burning additional fuel.
Because they work with any existing heating system, they are one of the more versatile and lower-risk interventions available. They also carry no gas safety considerations, making installation and ongoing maintenance relatively straightforward compared to gas-fired alternatives.
Works with Any Existing Heating System: No fuel costs beyond the electricity required to run the fan motor, making them a cost-effective complement to existing infrastructure.
Effective in High-Ceiling Buildings: Particularly useful where ceiling heights exceed four metres and stratification is a consistent problem.
Reduces Overall Heating Demand: By redistributing existing heat more evenly, they can contribute to lower overall energy consumption from the primary heating system.
No Gas Safety Requirements: Electrical installation only, with no Gas Safe registration requirements and no annual gas servicing obligations.
Low Maintenance: Large-diameter, low-speed operation means less wear than smaller, faster-spinning alternatives, with generally low ongoing maintenance requirements.
Warehouses with high ceilings where stratification is identified as a significant contributor to cold spots. Often most effective when used in conjunction with an existing gas heating system that is otherwise performing correctly.
Varies by fan diameter and the number of units required to cover the floor area. Generally represents a lower capital cost than additional gas heating appliances, with minimal ongoing running costs.
Best for: Spot-heating specific cold zones, loading bay areas, or workstations where a gas supply is not practical or cost-effective to extend.
Herschel manufactures a range of electric infrared heaters suited to commercial and industrial applications, from wall-mounted units for loading bays to ceiling-mounted panels for larger areas.
Electric infrared heaters work on the same principle as gas radiant tube heaters: they warm surfaces and occupants directly rather than heating the air. Where they differ is in their power source, which removes the need for a gas supply and the associated Gas Safe registration requirements for installation. This makes them a practical option for isolated cold spots where extending a gas supply would be disproportionately expensive.
They are best understood as a supplementary solution rather than a primary heating strategy for large spaces. Running costs are higher than gas for continuous, high-output use, so they are most cost-effective when used for targeted or intermittent heating rather than as a replacement for a gas-fired primary system.
No Gas Supply Required: Simpler installation in isolated cold spots or areas where gas infrastructure is absent or impractical to extend.
Immediate Heat Output: No warm-up period — heat is delivered as soon as the unit is switched on, making them well suited to intermittent use.
Supplementary Application: Works alongside a primary heating system to address specific cold zones without replacing the main infrastructure.
Wide Range of Output Ratings: Available in configurations to suit individual workstations through to larger loading bay areas.
Higher Running Costs for Continuous Use: Electric operation is generally more expensive than gas per unit of heat delivered — most cost-effective for targeted or intermittent heating rather than sustained background warmth.
Loading bay areas, individual workstations, or isolated cold spots where a gas supply is not available. Also useful as a short-term measure while a more comprehensive gas-fired solution is being specified and installed.
Unit costs typically range from approximately £150 to £800 or more depending on output rating. Running costs depend on your electricity tariff and hours of use — factor this carefully before specifying electric heating for continuous applications.
Best for: New-build warehouses or major refurbishment projects where even, low-level heat distribution is a design priority from the outset.
Wavin is one of several established suppliers of commercial underfloor heating systems, offering wet underfloor solutions designed to integrate with commercial boiler plant for large-scale applications.
Hydronic underfloor heating eliminates thermal stratification by design: heat rises from the floor upwards, warming the occupied zone first rather than the roof space. In temperature-sensitive storage environments, such as food distribution, pharmaceuticals, or precision manufacturing, this consistency of temperature distribution is particularly valuable.
The practical limitation is installation disruption. Retrofitting a wet underfloor system into an existing warehouse floor is a significant undertaking, and is generally only cost-effective when incorporated into new construction or a comprehensive refurbishment. For operational warehouses looking to address cold spots without major disruption, other options on this list are likely more practical in the short term.
Even, Low-Level Heat Distribution: Delivers heat from floor level upwards, eliminating stratification by design and providing consistent temperatures across the floor plate.
Suited to Temperature-Sensitive Environments: Particularly valued in food storage, pharmaceutical distribution, and other sectors where temperature consistency affects product integrity.
Most Practical for New-Build or Refurbishment: Retrofitting into an existing operational warehouse involves significant disruption to the floor slab and is rarely cost-effective as a standalone cold spot remedy.
Gas Safe Registered Installation Required for Boiler Element: The commercial boiler feeding the system must be installed and commissioned by a Gas Safe registered engineer.
Energy Efficiency Potential: When paired with a modern condensing boiler operating at appropriate flow temperatures, can contribute to improved overall energy efficiency.
New warehouse construction or major refurbishment projects where long-term operational efficiency and temperature consistency justify the capital investment. Not generally recommended as a retrofit solution for addressing cold spots in an operational building.
Represents a significant capital investment relative to other options on this list. Most cost-effective when incorporated into new construction or full refurbishment, where the floor slab is already being laid or replaced.
Best for: Warehouses where loading bay doors are a primary source of cold air infiltration and heat loss.
Biddle is a specialist manufacturer of air curtain systems for commercial and industrial applications, with a range of products designed for loading bay doors of varying widths and operational frequencies.
Loading bay doors are among the most common causes of warehouse cold spots, and one of the most straightforward to address. An air curtain creates a continuous stream of air across the door opening, forming a thermal barrier that significantly reduces cold air ingress without impeding the movement of forklifts, goods, or personnel. This is particularly relevant in North East warehouses where loading operations continue through winter months and doors may remain open for extended periods.
Air curtains do not heat the space themselves, but by reducing the volume of cold air entering the building, they reduce the load on the primary heating system and help maintain more consistent temperatures in the areas immediately adjacent to loading doors.
Addresses a Primary Cause of Cold Infiltration: Targets one of the most common and impactful sources of cold spots in operational warehouses.
Does Not Impede Operations: Allows forklift and pedestrian movement to continue uninterrupted, unlike physical door seals or dock shelters used in isolation.
Reduces Heating Load on Primary System: By limiting cold air ingress, reduces the demand placed on boilers, unit heaters, or radiant systems to compensate.
Electric-Powered with No Gas Safety Considerations: Straightforward electrical installation with no Gas Safe registration requirements.
Heated and Unheated Versions Available: Heated air curtains add a degree of active warming at the door threshold; unheated versions focus purely on the air barrier effect.
Warehouses with active loading bay operations where doors are regularly open during cold weather. Particularly effective when combined with other heating solutions rather than as a standalone intervention.
Varies by door width, model specification, and whether a heated version is required. Consult a specialist supplier for specification and pricing based on your door dimensions and operational pattern.
Best for: Larger or multi-use warehouse facilities where heating is not matched to occupancy patterns or zone-specific requirements.
Trend Controls is one of several established providers of building management systems for commercial premises, offering platforms that allow heating, ventilation, and other building services to be monitored, scheduled, and adjusted by zone.
Sometimes warehouse cold spots are not caused by inadequate heating capacity, but by heating that is not being delivered in the right place at the right time. An intelligent controls system allows different areas of a warehouse to be managed independently, ensuring that cold-prone zones receive adequate heat during occupied periods without over-heating areas that do not need it.
For facilities managers responsible for large or complex sites, a building management system also provides remote monitoring and the ability to identify and respond to heating anomalies before they become operational problems. This is increasingly relevant as commercial energy costs make precise control a financial priority as well as a comfort one.
Zone-by-Zone Control: Allows targeted heating of cold-prone areas independently of the rest of the building, without wasting energy on already-warm zones.
Scheduling for Occupancy Patterns: Reduces energy waste during unoccupied periods while ensuring the building reaches working temperature before staff arrive.
Integrates with Existing Heating Systems: Most modern BMS platforms can interface with existing commercial boilers, unit heaters, and radiant systems without requiring full system replacement.
Remote Monitoring and Adjustment: Allows facilities managers to review performance and make adjustments without being on site, supporting proactive rather than reactive management.
Supports Energy Efficiency Obligations: Helps commercial premises demonstrate responsible energy management, relevant to evolving compliance requirements for commercial buildings.
Larger warehouses and multi-use commercial facilities where heating is currently managed on a simple on/off basis and where cold spots may be partly attributable to scheduling or zoning gaps rather than insufficient heating capacity.
Costs vary considerably depending on system complexity, the number of zones, and the level of integration required with existing plant. A specialist controls contractor is required for design, installation, and commissioning.
The right approach depends on your warehouse layout, existing infrastructure, and the underlying cause of your cold spots. Before committing to capital expenditure on new equipment, it is worth establishing whether the problem lies with the heating system itself.
Many cold spots in North East warehouses are symptoms of a system that needs balancing, servicing, or upgrading rather than a fundamental gap in heating provision. A professional assessment by a Gas Safe registered engineer is often the most cost-effective first step, and can prevent unnecessary investment in supplementary equipment that addresses symptoms rather than causes.
For loading bay cold spots, air curtains are a targeted and relatively low-cost intervention. For high-bay buildings where stratification is the primary issue, gas radiant tube heaters or destratification fans are well-proven solutions. For facilities where controls are outdated or poorly matched to current occupancy patterns, a building management system can deliver meaningful improvements without any changes to the heating plant itself.
