Draper Jet Force Diesel and Kerosene Space Heater, 75,000 BTU/22kW

Step up to smarter site heating with the Draper DSH750 Jet Force Diesel and Kerosene Space Heater. Delivering 75,000 BTU (22kW) of heat across a suggested area of up to 10,000 cubic feet, this is the most feature-complete forced-air heater in the Draper Jet Force range — combining serious output with a thermostatic control unit, automatic ignition, photocell safety device and in-line fuel filter in a surprisingly compact and lightweight package.

Where many site heaters offer a simple on/off switch, the DSH750 lets you dial in your preferred temperature and maintain it automatically — saving fuel, improving comfort, and reducing the need for manual intervention throughout the working day. At just 12.8kg and sharing the same footprint as the DSH450, it packs 22kW of thermostatic heating power into one of the most portable formats in the range.

Compatible with both diesel and kerosene, with a 20-litre tank delivering approximately 10 hours of continuous operation, the DSH750 is built for users who want more than just heat — they want control.

Key Features

Thermostatic Temperature Control

The standout feature that separates the DSH750 from every other forced-air heater in the Draper DSH range is its built-in thermostatic control unit. Set your target temperature and the DSH750 manages its own output to maintain it — cycling as needed to hold a consistent working temperature rather than blasting at full power continuously. The result is better fuel economy in practice, a more comfortable working environment, and less hands-on management throughout the day.

Powerful 22kW / 75,000 BTU Output

With 22kW of heating capacity and 350m³/hr airflow, the DSH750 covers a suggested area of up to 10,000 cubic feet — enough for a generous double-bay workshop, a medium commercial unit, or a well-ventilated site building. It heats quickly and distributes warmth evenly across the working space.

Automatic Ignition

Press the button and the DSH750 fires cleanly and reliably every time. Automatic ignition means no manual lighting procedures, no delay, and no fuss — even in cold, damp site conditions.

Photocell Safety Device

The photocell safety device monitors the combustion flame throughout operation. If the flame is extinguished for any reason — a fuel interruption, strong draught, or fault — the photocell detects the loss of light and immediately shuts down fuel delivery, keeping the heater and its surroundings safe.

In-Line Fuel Filter for Consistent Performance

The in-line fuel filter ensures a clean, contaminant-free fuel supply reaches the burner at all times, protecting internal components and maintaining reliable ignition and efficient combustion throughout the heater's working life.

Multi-Fuel: Diesel & Kerosene Compatible

The DSH750 runs on both diesel and kerosene, giving you flexibility to use the most cost-effective or accessible fuel on site. Note: Grade 2 or higher kerosene is required.

Compact and Lightweight — 12.8kg

Despite its 22kW output, the DSH750 weighs just 12.8kg — barely more than the lower-output DSH450. The same compact dimensions make it easy to carry, store and reposition on site without dedicated equipment.

Specification

Where to Use the Draper DSH750

Important: The DSH750 is suitable for well-ventilated spaces only. It must not be used in sealed, airtight or poorly ventilated environments.

Ideal applications include:

• Double-Bay Workshops & Large Garages — Powerful thermostatic heating for larger working environments where consistent temperature control matters
• Construction Sites — High-output portable heating with automatic ignition for fast, reliable deployment on site
• Agricultural Buildings — Efficient heating for mid-sized barns, outbuildings and covered working areas
• Commercial Premises & Light Industrial Units — Thermostatic control suits environments where a consistent ambient temperature is important for work quality or comfort
• Site Cabins & Welfare Facilities — Fuel-efficient thermostat operation reduces running costs in occupied spaces used across long working days
• Events & Covered Outdoor Structures — Well-suited to marquees and temporary covered spaces with adequate ventilation

The Draper Jet Force Forced-Air Range

The DSH750 is the only forced-air heater in the Draper range with thermostatic control — making it the natural choice for anyone who wants precise, automatic temperature management alongside high heat output.

Why Choose the Draper DSH750?

In a range where most forced-air heaters offer an on/off switch and little else, the DSH750 stands apart. It's the only model in the Draper forced-air lineup to combine thermostatic temperature control with automatic ignition, photocell safety, and an in-line fuel filter — a specification that puts it firmly in the premium tier of portable site heaters.

Yet it doesn't ask you to sacrifice practicality for those features. At 12.8kg it's one of the lightest heaters in the range. Its compact dimensions make it as easy to store and transport as far less capable models. And its 22kW output covers meaningfully larger spaces than the entry-level Jet Force options.

For tradespeople, site managers and facility operators who want intelligent, efficient, well-controlled heating — rather than simply the most BTUs for the money — the DSH750 makes a very strong case.

Frequently Asked Questions

Is the DSH750 the only Draper forced-air heater with a thermostat? Yes — across the full Draper DSH forced-air range, the DSH750 is the only model fitted with a thermostatic control unit. The DSH-IR-B infrared heater also features thermostatic control, but among forced-air models the DSH750 is unique in offering this feature.

How does the thermostat work? The built-in thermostat monitors ambient temperature and adjusts the heater's output to maintain your chosen setting. Once the target temperature is reached, the heater modulates or cycles rather than running at full output continuously — improving fuel economy and maintaining a more consistent working temperature.

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

Can the DSH750 run on red diesel? Yes — the DSH750 is compatible with diesel including red (agricultural/commercial) diesel, as well as kerosene.

How large a space will it heat? Draper suggests the DSH750 is suitable for spaces up to 10,000 cubic feet. As a practical reference, a double-bay workshop measuring approximately 35ft x 24ft x 12ft falls within this coverage area.

How does the DSH750 compare to the DSH450? Both heaters share the same compact form factor and weight, but the DSH750 delivers 22kW versus the DSH450's 13kW — a 69% increase in output — and adds thermostatic temperature control. The DSH450 offers a longer runtime (~15 hours vs ~10 hours) at lower output, making it the better choice when fuel economy and extended runtime are the priority. The DSH750 is the right choice when you need more power and the precision of thermostatic control.

Is the DSH750 suitable for indoor use? The DSH750 is suitable for well-ventilated spaces only. It must not be operated in sealed or airtight rooms. Ensure adequate natural ventilation is present before use.
