Draper Jet Force Diesel and Kerosene Space Heater, 45,000 BTU/13kW

Fuel-efficient, reliable and built for long shifts, the Draper DSH450 Jet Force Diesel and Kerosene Space Heater is one of the most economical heaters in the Draper range. Delivering 45,000 BTU (13kW) of heat output across a suggested area of up to 8,000 cubic feet, it's well suited to smaller workshops, garages and well-ventilated site enclosures — and its 20-litre tank keeps it running for an exceptional 15 hours on a single fill.

With automatic ignition, a photocell safety device, and an in-line fuel filter for consistent fuel delivery, the DSH450 is a set-and-forget site heater that gets on with the job reliably, day after day. Running on both diesel and kerosene, it gives you flexibility on fuel choice without any compromise on performance.

Key Features

Outstanding Fuel Economy — 15-Hour Runtime

The DSH450's standout quality is its exceptional fuel efficiency. At a maximum consumption rate of just 1.3L/hr, the 20-litre tank delivers approximately 15 hours of continuous heat per fill — the longest runtime per tank in the Draper site heater range. For users running heaters through full working days or overnight, this dramatically reduces the frequency and cost of refuelling.

13kW / 45,000 BTU Output — Up to 8,000 cu. ft Coverage

With 13kW of heat output and 340m³/hr airflow, the DSH450 covers a suggested heating area of up to 8,000 cubic feet — equivalent to a generous single-bay workshop or small commercial space. It heats quickly and distributes warmth evenly throughout the working area.

Automatic Ignition

The automatic ignition system eliminates the need for manual lighting. Press the button and the DSH450 fires up cleanly and reliably — even in cold conditions — so you can get heat on site without fuss.

Photocell Safety Device

The photocell safety device monitors the combustion flame continuously during operation. If the flame is interrupted or extinguished for any reason, the photocell immediately cuts fuel delivery and shuts the heater down, preventing the accumulation of unburned fuel and ensuring safe operation.

In-Line Fuel Filter for Reliable Operation

The in-line fuel filter protects the combustion system from fuel contaminants, delivering a clean, consistent fuel supply to the burner time after time. This helps maintain reliable ignition and efficient combustion across the heater's working life.

Multi-Fuel: Diesel & Kerosene Compatible

The DSH450 operates on both diesel and kerosene, giving you the freedom to use whichever fuel is more cost-effective or available on site. Note: Grade 2 or higher kerosene is required.

Lightweight and Portable — 12.7kg

At just 12.7kg, the DSH450 is one of the lightest heaters in the Draper range, making it easy to carry and reposition around a workshop or site as needed.

Specification

Where to Use the Draper DSH450

Important: The DSH450 is suitable for well-ventilated spaces only. It must not be used in sealed, airtight or poorly ventilated environments.

Ideal applications include:

• Smaller Workshops & Garages — Efficient, consistent heating for single-bay working environments
• Site Cabins & Welfare Units — Long runtime and low fuel consumption suit spaces that need heat across a full working day
• Construction Sites — Portable, fuel-flexible heating for well-ventilated on-site enclosures
• Agricultural Outbuildings — Cost-effective warmth for smaller barns, stores and covered work areas
• Temporary Site Offices — Quiet enough and efficient enough for occupied working spaces with good airflow
• Jobsite Heating — Lightweight and easy to move between locations on site

How Does the DSH450 Compare?

The DSH450 sits alongside the DSH58 as one of the entry-level heaters in the Draper forced-air range — but with a different balance of output and runtime. Here's how it fits across the full line-up:

The DSH450 trades a modest reduction in raw output against a longer runtime, automatic ignition and built-in safety features — making it the smarter choice when fuel economy and ease of use matter as much as maximum heat.

Why Choose the Draper DSH450?

The DSH450 occupies a distinct position in the Draper range: it's not simply a smaller version of a bigger heater — it's a more refined, feature-rich option for users who prioritise reliability, running costs and ease of operation.

The combination of automatic ignition, photocell safety monitoring and an in-line fuel filter gives it a technical specification more commonly found on premium heaters. Pair that with the best runtime-per-litre in the range and you have a heater that genuinely rewards users who run it day in, day out.

For workshops, contractors and site managers who want a portable heater that's simple to start, safe in operation, and cheap to run — the DSH450 makes a compelling case.

Frequently Asked Questions

What makes the DSH450 different from the DSH58? Both are entry-level forced-air diesel and kerosene heaters, but the DSH450 has several practical advantages: automatic ignition (no manual start required), a photocell safety device, an in-line fuel filter, a longer 15-hour runtime, and a lighter overall weight of 12.7kg. The DSH58 produces slightly more output (15kW vs 13kW) and higher airflow, making it the stronger choice purely for heat output in a larger space.

What grade of kerosene is required? Grade 2 or higher kerosene is required. Standard 28-second heating kerosene typically meets this specification — always check the grade with your fuel supplier before use.

Can it run on red diesel? Yes — the DSH450 is compatible with both diesel (including red/agricultural diesel) and kerosene.

How long will a full tank last? At maximum consumption of 1.3L/hr, a full 20-litre tank provides approximately 15 hours of continuous operation. This is the longest runtime per tank of any heater in the Draper DSH forced-air range.

Is the DSH450 suitable for indoor use? The DSH450 is suitable for well-ventilated spaces only. It must not be operated in sealed or airtight rooms. Always ensure adequate natural ventilation is present before use.

How large a space will it heat? Draper suggests the DSH450 is suitable for spaces up to 8,000 cubic feet. As a reference point, a single-bay workshop measuring roughly 30ft x 20ft x 13ft falls within this range.
