Diesel Heaters

About Diesel Heaters

Diesel heaters, also known as diesel space heaters or kerosene heaters, are powerful heating solutions designed to provide efficient warmth in large, unheated spaces where traditional heating systems aren't practical. These robust heaters are essential equipment for workshops, warehouses, construction sites, garages, and agricultural buildings throughout the UK. Operating on diesel fuel or paraffin (kerosene), they deliver impressive heat output measured in kilowatts (kW) or BTU, capable of warming substantial areas quickly and cost-effectively even during the coldest British winters.

MyToolShed.co.uk stocks a comprehensive range of diesel heaters from trusted brands including Sealey and Draper, offering models with varying heat outputs to suit different space sizes and applications. Our selection includes both direct-fired jet force heaters, which provide maximum heat output and are ideal for well-ventilated spaces, and models with ducting capabilities for use in more enclosed environments. Whether you're a building contractor needing temporary site heating or a tradesperson maintaining a comfortable workshop, these industrial-grade heaters feature durable steel construction, integrated fuel tanks, and safety features including flame-out protection and overheat cut-offs.

Applications

Diesel heaters are essential equipment for a wide range of trades and industries across the UK:

• Building Contractors and Site Managers – providing temporary heating for construction sites, enabling work to continue during cold weather and helping plaster, concrete, and paint to cure properly
• Agricultural Workers and Farmers – maintaining appropriate temperatures in livestock buildings, protecting animals during lambing and calving seasons, and preventing frost damage in storage barns
• Warehouse and Logistics Operators – keeping large storage and distribution facilities at working temperatures for staff comfort and product protection
• Event Managers and Marquee Hire Companies – heating temporary structures for weddings, exhibitions, and outdoor events throughout the year
• Motor Mechanics and Vehicle Repairers – maintaining comfortable working temperatures in garages and bodyshops during winter months
• Plant Hire and Tool Rental Businesses – providing heating equipment to contractors and businesses on a short-term basis

Choosing The Right Diesel Heaters

Selecting the appropriate diesel heater requires careful consideration of several key factors:

Heat Output Requirements: Calculate the size of the space you need to heat in cubic metres and consider the level of insulation. As a general rule, you'll need approximately 30-40 watts per cubic metre for a well-insulated space, or 40-60 watts for poorly insulated areas. MyToolShed.co.uk offers models ranging from compact units suitable for smaller workshops up to powerful heaters capable of heating large warehouses.

Fuel Tank Capacity: Larger integrated fuel tanks mean longer running times between refills. If you need continuous heating throughout a working day, look for models with substantial tank capacities, typically ranging from 20 to 60 litres across our Sealey and Draper ranges.

Portability Features: Consider whether you'll be moving the heater regularly between locations. Look for models with sturdy wheels, comfortable carry handles, and manageable weights for easy site-to-site transportation.

Safety Features: Essential safety elements include flame-out protection, overheat cut-off switches, and stable bases to prevent tipping. Models with electronic ignition systems are generally more reliable and comply with current HSE guidelines for workplace heating equipment.

Safety Information

Ventilation Requirements: Direct-fired diesel heaters consume oxygen and produce combustion gases including carbon dioxide. Always ensure adequate ventilation when operating these heaters indoors, with a minimum of two permanent ventilation openings in any space using combustion heating equipment.

Fuel Handling: Store diesel and paraffin fuels in approved containers away from heat sources. Always refuel heaters outdoors or in well-ventilated areas after the unit has cooled completely, and never smoke or allow naked flames nearby during refuelling.

Clearance Distances: Maintain at least one metre clearance from combustible materials, walls, and ceilings. Position heaters on stable, level, non-combustible surfaces away from high-traffic areas.

Electrical Safety: Most diesel heaters require 240v mains electricity for fan operation and ignition systems. Use RCD protection when operating on construction sites as required by current electrical safety regulations.

Frequently Asked Questions

Can I use red diesel in my space heater?

Yes, diesel heaters can operate on both standard white diesel and red diesel (rebated fuel oil). It's legal to use red diesel in static heating equipment for construction sites, agricultural buildings, and other non-road applications, making it a cost-effective choice for space heating.

How much does it cost to run a diesel heater?

Running costs depend on the heater's output and fuel consumption rate. A typical 30kW diesel heater consumes approximately 2-3 litres of fuel per hour at full output. With current diesel prices, you can expect running costs of around £3-£5 per hour for a medium-sized unit. Using a thermostat and running the heater at lower outputs when appropriate can significantly reduce fuel consumption.

Do I need special qualifications to operate a diesel heater?

No specific qualifications are legally required to operate diesel space heaters in the UK, but users should be trained in safe operation procedures, particularly regarding fuel handling, ventilation requirements, and fire safety. Employers have a duty under HSE regulations to ensure workers are competent to use equipment safely.
