Fan Heaters

About Fan Heaters

Fan heaters are portable heating solutions designed to deliver fast, effective warmth to workshops, construction sites, warehouses, and commercial spaces. Using an integrated fan to blow air across heated elements, these units rapidly distribute heat throughout the workspace, making them ideal for quickly raising temperatures in cold environments or providing localised heating where it's needed most. MyToolShed.co.uk stocks a comprehensive range of industrial fan heaters from Sealey, offering robust, professional-grade heating equipment built to withstand demanding site conditions.

From compact ceramic fan heaters perfect for smaller workshops to powerful 9kW three-phase industrial models capable of heating large commercial spaces, these units deliver reliable performance when temperatures drop. Available in both standard 240V single-phase and 415V three-phase configurations, fan heaters provide flexible heating solutions for tradespeople, facilities managers, and industrial users. Modern models incorporate safety features including overheat protection, tip-over switches, adjustable thermostats, and durable metal casings designed for professional use.

Applications

Fan heaters are essential equipment for numerous trades and industries:

• Builders and construction workers requiring temporary heating on building sites during winter months
• Vehicle mechanics and automotive technicians maintaining comfortable temperatures in garages and repair centres
• Warehouse and logistics managers providing supplementary heating in large storage facilities
• Agricultural workers protecting livestock and equipment in barns and outbuildings
• Painters and decorators accelerating drying times and maintaining optimal working conditions
• Plasterers and drywall specialists creating ideal conditions for materials to cure properly
• Manufacturing and production facilities ensuring consistent temperatures for quality control
• Event organisers providing temporary heating for marquees and outdoor function spaces
• DIY enthusiasts heating garages, sheds, and home workshops during colder months

Choosing The Right Fan Heaters

Power Output: Calculate the required kW rating based on your workspace dimensions. As a general guide, you'll need approximately 100W per square metre for well-insulated spaces. A 2-3kW heater suits small workshops and garages, whilst 5kW+ industrial models are necessary for larger commercial spaces or construction sites.

Electrical Supply: Determine whether you have single-phase (240V) or three-phase (415V) power available. Most domestic and small workshop locations use standard 240V supply, whilst larger industrial premises often have three-phase infrastructure. Three-phase heaters offer greater power output but require appropriate electrical installation.

Safety Features: Prioritise models with overheat protection, automatic cut-off switches, and tip-over safety features. PTC ceramic heating elements offer enhanced safety through self-regulating temperature control, reducing fire risk in dusty or cluttered workshops.

Portability: Consider whether you need a lightweight portable unit for moving between locations or a more substantial fixed heater. Look for integrated carry handles and durable construction suitable for your intended use.

Safety Information

Always ensure adequate ventilation when operating fan heaters, particularly in enclosed spaces. Never cover fan heaters or position flammable materials nearby – maintain at least one metre clearance on all sides. Place heaters on stable, level surfaces away from water sources and high-traffic areas where they might be knocked over. Regularly inspect power cables for damage and ensure extension leads are rated for the heater's power requirements. For industrial three-phase heaters, ensure installation is carried out by qualified electricians in accordance with BS 7671 wiring regulations.

Frequently Asked Questions

What size fan heater do I need for my workshop?

Calculate approximately 100 watts per square metre for well-insulated spaces. A typical single garage (3m x 6m) requires around 2-3kW, whilst a double garage or small workshop needs 3-5kW. Consider ceiling height, insulation quality, and external temperatures when determining requirements.

Can I run an industrial fan heater from a standard 13A socket?

Yes, but only heaters rated up to 3kW. A 2kW heater draws around 8.7A, whilst a 3kW unit draws approximately 13A – the maximum for standard UK domestic sockets. Higher-output models typically require dedicated circuits or three-phase supply. Always check your heater's amperage rating and ensure your electrical circuit can handle the load safely.

Are fan heaters expensive to run?

Running costs depend on wattage and usage duration. A 2kW heater costs approximately 60p per hour, whilst a 3kW model costs around 90p per hour based on typical commercial electricity rates. MyToolShed.co.uk recommends using the thermostat effectively and only heating when necessary to significantly reduce costs.
