Draper 230V Diesel and Kerosene Space Heater, 68,250 BTU/20kW

Bridging the gap between compact portability and serious industrial power, the Draper DSH68 Diesel and Kerosene Space Heater is the mid-range workhorse of the Draper site heater range. Delivering 68,250 BTU (20kW) of heat output with an airflow of 450m³/hr, it's powerful enough to warm medium-to-large workshops, garages and commercial spaces — while remaining practical enough to move around site on its wheeled steel frame.

Like all heaters in the Draper DSH range, it features a compressor pump for high-efficiency clean burning, ensuring maximum heat from every litre of fuel. The 19-litre tank runs for approximately 10 hours at 1.87L/hr consumption — a solid full-day performance from a single fill.

Key Features

High-Efficiency Compressor Pump

The DSH68 uses a compressor pump to atomise fuel cleanly and efficiently, delivering a better quality burn than simpler gravity-fed designs. The result is more heat per litre, lower running costs, and cleaner operation in semi-open environments.

Powerful 20kW / 68,250 BTU Output

With 20kW of heating capacity and 450m³/hr airflow, the DSH68 moves a substantial volume of warm air across medium and large spaces. It heats quickly and evenly — reducing the cold-start wait and maintaining consistent temperatures throughout your working area.

Multi-Fuel: Diesel & Kerosene Compatible

The DSH68 gives you the flexibility to run on either diesel or kerosene, so you can use whichever fuel is most cost-effective or readily available on site. Note: Grade 2 or higher kerosene is required.

10-Hour Runtime from a 19-Litre Tank

At a consumption rate of 1.87L/hr, the 19-litre tank delivers approximately 10 hours of continuous heat per fill — enough to cover a full working day without refuelling.

Wheeled Steel Frame for Easy Site Mobility

The DSH68 is mounted on a sturdy wheeled steel frame, making it straightforward to reposition around a workshop, across a factory floor, or between locations on a jobsite — without any heavy lifting required.

Robust Steel Build with Powder Coat Finish

Constructed from high-quality steel with a gloss black powder coat finish, the DSH68 is built to handle the bumps and rough conditions of professional and industrial use season after season.

Simple On/Off Operation

A straightforward on/off switch means there's nothing complicated to learn. Switch it on, and it gets straight to work.

Specification

Where to Use the Draper DSH68

Important: This heater is suitable for open and semi-open environments only. It must not be used in sealed or poorly ventilated spaces.

The DSH68 is well suited to:

• Workshops — Consistent, powerful heat across a medium-to-large workspace
• Garages — Ideal for multi-bay garages or larger single-vehicle workshops
• Factories & Industrial Units — Supplementary heating for open production areas
• Construction Sites & Jobsites — Portable, fuel-flexible heat wherever mains systems aren't available
• Agricultural Buildings — Barns, outbuildings and covered yards with good natural airflow
• Storage Facilities & Warehouses — Prevent cold-related damage to stock, equipment or materials

How Does the DSH68 Compare?

Not sure which Draper space heater is right for your space? Here's how the full DSH range stacks up:

The DSH68 hits the sweet spot for users who need more power than the DSH58 can deliver but don't require the full industrial output of the DSH108. It's the natural choice for larger garages, multi-bay workshops and medium-sized commercial environments.

Why Choose the Draper DSH68?

Draper Tools has been manufacturing and supplying professional-grade equipment for over a century. The DSH68 reflects that pedigree — it's a practical, hard-wearing heater that balances genuine heating performance with ease of use and site mobility.

The step up from 15kW to 20kW makes a meaningful difference in larger spaces where the smaller DSH58 might struggle to maintain temperature. Combined with the wheeled frame for easy movement and the efficient compressor pump, the DSH68 gives you industrial-level heat in a format that's genuinely manageable for one person on site.

Frequently Asked Questions

What grade of kerosene does the DSH68 require? Grade 2 or higher kerosene is required. Standard heating kerosene (28-second) available from fuel suppliers typically meets this requirement — always check the grade specification before filling.

Can the DSH68 run on red diesel? Yes — the DSH68 is compatible with standard diesel including red (agricultural/commercial) diesel, which can offer significant cost savings for farm and commercial site users.

Is the DSH68 safe to use inside a building? The DSH68 is only suitable for use in open or semi-open environments with good natural ventilation — such as workshops, factories, barns and open-sided structures. It must not be used in sealed domestic rooms or airtight spaces.

How long does a full tank last? At 1.87L/hr consumption, a full 19-litre tank provides approximately 10 hours of continuous operation — enough for a full working day on a single fill.

How does the DSH68 differ from the DSH58? The DSH68 produces 20kW versus the DSH58's 15kW, giving a 33% increase in heat output. It also has a higher airflow rate (450m³/hr vs 400m³/hr) and is mounted on a wheeled frame rather than a carry handle — making it better suited to larger spaces and heavier-duty site use.

What power supply is required? A standard 230V mains supply is all that's needed. The 220W motor powers the compressor pump and fan, while all primary heat output comes from fuel combustion.
