Draper Jet Force Diesel and Kerosene Space Heater, 175,000 BTU/51kW

When only the most powerful will do, the Draper DSH1750 Jet Force Diesel and Kerosene Space Heater is the answer. Producing a formidable 175,000 BTU (51kW) of heat output — the highest of any heater in the entire Draper DSH range — it's built for the largest industrial, agricultural and commercial spaces where smaller heaters simply can't keep up.

With a suggested heating area of up to 28,000 cubic feet and an airflow of 508m³/hr, the DSH1750 pushes heat across vast floor areas quickly and evenly. Yet for all its industrial scale, it operates with genuine intelligence: a thermostatic control unit manages output automatically to maintain your chosen temperature, while automatic ignition, a photocell safety device and an in-line fuel filter ensure reliable, safe and consistent operation throughout.

The 50-litre tank — the largest in the Draper range — delivers approximately 10 hours of continuous running at maximum output. With thermostatic cycling, real-world runtime will extend further, reducing refuelling frequency during long working days.

For large-scale industrial heating applications, this is as capable as Draper's portable heater range gets.

Key Features

The Most Powerful Heater in the Draper Range — 51kW / 175,000 BTU

At 51kW, the DSH1750 produces more heat than any other heater in the Draper DSH lineup — 42% more than the next most powerful forced-air model (DSH1250, 36kW) and nearly double the output of the mid-range DSH68 (20kW). If your space has defeated every other heater you've tried, this is the one to reach for.

Covers Up to 28,000 Cubic Feet

With a suggested coverage area of 28,000 cubic feet, the DSH1750 handles spaces that most portable heaters can only make a dent in. A large warehouse bay, a major agricultural building, a substantial industrial unit, or a significant construction site interior — this heater is built to warm them all.

Thermostatic Control for Intelligent, Efficient Operation

Despite its raw power, the DSH1750 operates smartly. The thermostatic control unit continuously monitors ambient temperature and modulates output to maintain your chosen setting — rather than running flat out until the space overheats or you manually intervene. Over a 10-hour shift, this thermostatic efficiency delivers meaningful fuel savings and a more consistent working environment. Across the full Draper forced-air range, only the DSH750 (22kW) and DSH1250 (36kW) also offer this feature.

50-Litre Tank — The Largest in the Range

The 50-litre fuel tank is the biggest fitted to any heater in the Draper DSH range. At a maximum consumption of 5L/hr it delivers around 10 hours at full output, and with thermostatic cycling that runtime extends further still in normal use. On a large site where refuelling interruptions cause real disruption, the DSH1750's tank capacity is a genuine operational advantage.

Automatic Ignition

Automatic ignition fires the DSH1750 cleanly and reliably at the press of a button — no manual lighting procedures, no delay, even in cold and damp site conditions.

Photocell Safety Device

The photocell safety device monitors the combustion flame continuously. If the flame is interrupted or extinguished for any reason, it immediately shuts down fuel delivery — preventing unburned fuel accumulation and keeping the heater and its surroundings safe, including during unattended operation.

In-Line Fuel Filter

The in-line fuel filter ensures a clean, consistent fuel supply reaches the burner at all times, protecting internal components from contamination and maintaining reliable combustion across the heater's full working life.

Multi-Fuel: Diesel & Kerosene Compatible

The DSH1750 runs on both diesel and kerosene — giving flexibility to use the most cost-effective or accessible fuel on site. Note: Grade 2 or higher kerosene is required.

Specification

Where to Use the Draper DSH1750

Important: The DSH1750 is suitable for well-ventilated spaces only. It must not be used in sealed, airtight or poorly ventilated environments.

The DSH1750 is designed for the largest and most demanding heating applications:

• Large Warehouses & Distribution Centres — Supplement fixed heating or provide primary temporary heat across major floor areas
• Industrial Units & Factories — Consistent, powerful heat across high-ceilinged or expansive open production environments
• Agricultural Buildings — Heating for large livestock barns, covered yards, poultry houses and major agricultural structures with adequate ventilation
• Major Construction Sites — Maximum-output portable heating for large building interiors, concrete curing environments and cold-weather site operations
• Large Commercial Premises — Powerful supplementary heating for big retail, trade or commercial spaces with sufficient ventilation
• Events & Large Covered Venues — High-capacity heating for large event halls, exhibition spaces and temporary structures with good airflow

The Complete Draper Jet Force Forced-Air Range

The DSH1750 sits at the top of the range on every headline metric: output, coverage area and tank capacity. Alongside the DSH750 and DSH1250, it is one of three forced-air models in the range to feature thermostatic control.

Why Choose the Draper DSH1750?

There are heaters that warm a space, and there are heaters that transform it. For spaces large enough to defeat conventional site heaters — high-ceilinged warehouses, major agricultural buildings, large industrial units — the DSH1750 is the difference maker.

Its 51kW output, 28,000 cu. ft coverage and 50-litre tank give it the raw capacity to heat at a scale most portable heaters can only approximate. Its thermostatic control, automatic ignition, photocell safety and in-line filter mean it does so intelligently, safely and reliably.

At 26kg it remains manageable on site, and its clean-burn diesel and kerosene compatibility keeps running costs practical even at high output. For the most demanding large-space heating challenges, this is Draper's definitive answer.

Frequently Asked Questions

Is the DSH1750 the most powerful heater Draper makes? Yes — the DSH1750 produces 51kW / 175,000 BTU, making it the highest-output heater across the entire Draper DSH range, including both forced-air and infrared models.

Does the DSH1750 have a thermostat? Yes — the DSH1750 features a thermostatic control unit that automatically maintains your chosen temperature, modulating output as needed. Across the full forced-air range, only the DSH750 (22kW) and DSH1250 (36kW) also offer this feature.

How large a space will it heat? The DSH1750 is suggested for spaces up to 28,000 cubic feet. As a practical reference, this covers a warehouse or industrial unit approximately 70ft x 40ft x 10ft, or a similarly proportioned large agricultural building.

How long will a full tank last? At maximum consumption of 5L/hr, the 50-litre tank delivers approximately 10 hours at full output. With thermostatic control reducing output once the target temperature is reached, real-world runtime will typically extend beyond this during normal use.

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 DSH1750 run on red diesel? Yes — the DSH1750 is compatible with diesel including red (agricultural/commercial) diesel, as well as kerosene.

How does the DSH1750 compare to the DSH1250? The DSH1250 delivers 36kW / 125,000 BTU from a 40-litre tank, covering up to 15,000 cu. ft. The DSH1750 steps up to 51kW / 175,000 BTU from a 50-litre tank, covering up to 28,000 cu. ft — nearly double the coverage area. Both feature thermostatic control, automatic ignition and photocell safety. Choose the DSH1250 for large spaces; choose the DSH1750 for the very largest.

Is the DSH1750 safe to use inside a building? The DSH1750 is suitable for well-ventilated spaces only. It must not be used in sealed, airtight or poorly ventilated environments. Always ensure adequate natural ventilation is present before operating.
