Cabinet Heaters

About Cabinet Heaters

Cabinet heaters are robust, portable heating solutions engineered to deliver reliable warmth in workshops, garages, construction sites, and industrial environments. Unlike standard fan heaters, these units feature durable metal enclosures that protect internal heating elements whilst distributing heat effectively across medium to large spaces. MyToolShed.co.uk stocks both electric infrared and gas butane cabinet heaters from trusted brands including Sealey and Draper, ensuring professional-grade performance for tradespeople and serious DIY enthusiasts.

Electric infrared cabinet heaters operate on standard 240v mains power, using radiant heat technology to warm objects and people directly rather than simply heating the air—ideal for draughty workshops. Gas butane models offer exceptional portability without requiring electrical connections, making them perfect for remote sites or outdoor covered areas where mains power isn't available.

Applications

Cabinet heaters are essential equipment across numerous trades and environments:

• Motor mechanics and vehicle restorers maintaining comfortable temperatures in uninsulated garages during winter repairs
• Construction workers and site managers providing temporary heating in partially completed buildings
• Joiners and cabinet makers keeping workshops warm for optimal glue curing and varnish drying
• Agricultural workers heating machinery sheds and livestock buildings
• Warehouse and storage facilities spot-heating specific work zones without heating entire spaces
• Electricians and plumbers working in cold environments where manual dexterity is critical
• Event organisers providing temporary heating for marquees and outdoor covered venues
• DIY enthusiasts extending workshop usability throughout colder months

Choosing The Right Cabinet Heaters

Power Source: Consider whether 240v mains electricity is available. Electric infrared models require mains power but offer cleaner operation in enclosed spaces. Gas butane heaters provide complete portability for remote sites without electrical concerns.

Heating Capacity: Calculate your space requirements—approximately 100 watts per square metre for well-insulated areas, up to 150 watts per square metre for poorly insulated spaces. Check kW ratings (electric) or BTU output (gas) match your needs.

Portability: Look for units with robust carry handles, integrated castors, and manageable weight if frequent relocation is required. Gas models typically offer greater flexibility for multi-site use.

Safety Features: Essential mechanisms include automatic tip-over switches, overheat protection, and flame failure devices on gas models. Ensure CE marking and compliance with HSE guidelines for professional environments.

Running Costs: Electric heaters' operational expenses depend on your electricity tariff and kW rating. Gas models' costs relate to butane canister prices and consumption rates, typically measured in grams per hour.

Safety Information

Ventilation: Gas cabinet heaters must only operate in adequately ventilated areas. Even models with oxygen depletion sensors require continuous fresh air circulation to prevent carbon monoxide buildup.

Clearance Distances: Maintain minimum clearances as specified by manufacturers—typically at least 1 metre from combustible materials, walls, and ceilings. Never use heaters to dry clothing.

Electrical Safety: Plug 240v electric heaters directly into properly rated wall sockets rather than light-duty extension leads. Ensure electrical supply matches the heater's voltage and wattage requirements.

Supervision: Position heaters on stable, level, non-combustible surfaces. Never leave gas models unattended or operating overnight in occupied spaces.

Frequently Asked Questions

What's the difference between infrared and gas cabinet heaters?

Infrared electric models operate on 240v mains power, using radiant heating to warm objects directly—ideal for fixed workshop locations with electricity access. Gas butane heaters burn fuel for heat generation, offering complete portability without electrical requirements but needing adequate ventilation and regular canister replacement. MyToolShed.co.uk stocks both types to suit different working environments.

How much space can a cabinet heater effectively warm?

A typical 3kW electric cabinet heater effectively heats approximately 20-30 square metres of reasonably insulated workshop space. Gas models with 4.2kW output manage similar areas. Poorly insulated spaces or draughty conditions significantly reduce coverage. Allow 100-150 watts per square metre depending on insulation quality for accurate calculations.

Are cabinet heaters expensive to run?

Running costs vary by type. A 3kW electric heater costs approximately 75-100p per hour based on typical UK electricity prices. Gas butane heaters consume roughly 300-400g per hour, with costs varying by supplier. Using thermostatic controls and heating only occupied periods significantly reduces operational expenses.
