How to Choose the Right Fan Heaters

Power Output and Space Size: Calculate the required kW rating based on your workspace dimensions. As a general guide, you'll need approximately 100W per square metre for a well-insulated space, more for draughty or poorly insulated areas. A 2-3kW heater suits small workshops and garages, whilst 5kW+ industrial models are necessary for larger commercial spaces or outdoor 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 and construction sites often have three-phase infrastructure. Three-phase heaters offer greater power output but require appropriate electrical installation and certification.

Portability Requirements: Consider whether you need a lightweight portable unit for moving between locations or a more substantial fixed heater. Look for integrated carry handles, durable construction, and appropriate weight for your intended use. Industrial models typically feature robust metal casings that withstand site conditions but may be heavier than domestic alternatives.

Safety Features: Prioritise models with overheat protection, automatic cut-off switches, and tip-over safety features, especially if the heater will be used in busy environments or left unattended. PTC ceramic heating elements offer enhanced safety through self-regulating temperature control, reducing fire risk in dusty or cluttered workshops.

Control Options: Adjustable thermostats allow precise temperature management and help control running costs by preventing unnecessary heating. Multiple heat settings provide flexibility for different applications and seasons. Some industrial models include built-in timers for automated operation schedules.

Running Costs: Higher wattage heaters consume more electricity, so balance heating power against energy efficiency. A 3kW heater running for one hour costs approximately 90p based on current industrial electricity rates. Consider whether intermittent heating or continuous lower-power operation better suits your requirements.

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. Fan heaters should be placed 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 never use extension leads rated below the heater's power requirements. For industrial three-phase heaters, ensure installation and maintenance is carried out by qualified electricians in accordance with BS 7671 wiring regulations. The HSE recommends regular PAT testing for portable electrical heating equipment used in commercial environments.

Never leave fan heaters unattended for extended periods unless they feature appropriate safety cut-offs and are designed for continuous operation. Turn heaters off before refuelling vehicles or using flammable substances in workshops. Ensure filters and air intakes are kept clean to prevent overheating and maintain efficient operation.

Frequently Asked Questions

What size fan heater do I need for my workshop?
Calculate approximately 100 watts per square metre for well-insulated spaces, more for draughty areas. A typical single garage (3m x 6m = 18m²) requires around 2-3kW, whilst a double garage or small workshop needs 3-5kW. Browse the selection at Tooled-Up.com for larger industrial spaces that benefit from multiple heaters or high-output 5-9kW models. 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 (approximately 13A at 240v). Higher-output models typically require dedicated circuits or three-phase supply. A 2kW heater draws around 8.7A, whilst a 3kW unit draws approximately 13A – the maximum for standard UK domestic sockets. 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. Using the thermostat effectively and only heating when necessary significantly reduces costs. Fan heaters provide fast warmth but aren't the most economical option for continuous all-day heating compared to permanently installed systems.

What's the difference between ceramic and standard element fan heaters?
Ceramic fan heaters use self-regulating PTC (Positive Temperature Coefficient) ceramic plates that heat rapidly and maintain consistent temperatures automatically. They're generally safer, more efficient, and longer-lasting than traditional wire element heaters. Ceramic elements respond quickly to thermostat demands and are less prone to failure. Standard element heaters are typically less expensive initially but may consume more energy and require more frequent replacement.

Can industrial fan heaters be used outdoors?
Industrial fan heaters can be used in semi-outdoor environments like open garages, covered construction sites, and marquees, but shouldn't be exposed to direct rain or moisture. Check the IP rating – higher ratings indicate better protection against dust and water ingress. Position heaters in sheltered areas and ensure electrical connections remain dry. For fully exposed outdoor locations, consider purpose-built outdoor heaters with appropriate weatherproofing certifications.
