Draper Jet Force Infrared Diesel Space Heater, 124,000 BTU/34kW

When you need maximum infrared heating power, the Draper DSH-IR30-B Jet Force Infrared Diesel Space Heater delivers it. Producing a formidable 124,000 BTU (34kW) of radiant heat output, this is the most powerful heater in the Draper DSH range — built for large industrial spaces, warehouses, agricultural buildings and commercial sites where only serious heat will do.

Like all infrared heaters, the DSH-IR30-B warms people, equipment and surfaces directly rather than simply heating the surrounding air. This makes it exceptionally effective in large, open or draughty environments where forced-air heat would dissipate before reaching the people who need it. Automatic ignition gets it running instantly, while a photocell safety device and overheating protection keep it running safely.

The 40-litre tank provides extended operation between refills — and at just 94W motor draw, it runs with remarkably low electrical noise for a heater of this output. This is industrial-grade infrared heating in its most powerful portable form.

Key Features

Exceptional 34kW / 124,000 BTU Infrared Output

At 34kW, the DSH-IR30-B produces over twice the radiant heat of the smaller DSH-IR-B — making it the right tool for genuinely large-scale heating challenges. Whether you're warming a high-ceilinged warehouse, a large open-sided agricultural building, or a major construction site interior, this heater has the output to make a real difference.

Infrared Radiant Heat Technology

Infrared heaters work fundamentally differently from forced-air models. Rather than warming the air, they emit radiant heat that is absorbed directly by objects, surfaces and people in the heater's line of sight — much like the warmth of the sun. In large, draughty or open-sided spaces where warm air simply escapes, infrared is often the only practical heating solution. The DSH-IR30-B is engineered to deliver that radiant heat at industrial scale.

Automatic Ignition

No manual lighting, no pilot flames — the automatic ignition system fires the DSH-IR30-B reliably at the press of a button. Fast, convenient and consistent, even in cold conditions.

Photocell Safety Device with Heat Protection

The photocell safety device continuously monitors the combustion flame during operation. If the flame is extinguished unexpectedly — due to a fuel issue, strong draught or fault — the photocell detects the absence of light and shuts the heater down automatically. Combined with overheating protection, the DSH-IR30-B is built to operate safely even in demanding environments.

40-Litre Tank for Extended Runtime

The large 40-litre fuel tank significantly reduces the frequency of refuelling stops on long working days. At a maximum consumption of 2.6L/hr, it provides substantial continuous operation between fills — keeping the heat on and interruptions to a minimum.

Low Electrical Draw — 94W Motor

Despite its enormous heat output, the DSH-IR30-B's electric motor draws just 94W — the same as the smaller DSH-IR-B. This means it places minimal demand on site power supplies and runs with significantly less fan noise than forced-air heaters of comparable BTU output.

Diesel Fuel Compatibility

The DSH-IR30-B runs on diesel, including red (agricultural/commercial) diesel — a cost-effective and widely available fuel for farm, industrial and construction site use.

Specification

Where to Use the Draper DSH-IR30-B

Important: This heater is suitable for well-ventilated spaces only. It must not be operated in sealed, airtight or poorly ventilated environments.

The DSH-IR30-B is built for large-scale applications including:

• Warehouses & Distribution Centres — Infrared spot heating for large floor areas, loading bays and picking zones
• Large Workshops & Industrial Units — Consistent radiant warmth across expansive working environments
• Agricultural Buildings — Effective heating for large barns, stables, poultry houses and covered yards
• Construction Sites — Powerful temporary heating for large building interiors during fit-out or cold-weather working
• Open-Sided & Open-Fronted Structures — Where forced-air heat would be lost, infrared delivers warmth directly to the people and surfaces that need it
• Events & Large Covered Venues — High-output heating for marquees, event halls and temporary structures with good airflow

The Draper Infrared Heater Range

For medium-sized workshops and well-ventilated spaces, the DSH-IR-B offers 17kW output with the added benefit of thermostatic temperature control. For the largest industrial, agricultural and commercial applications, the DSH-IR30-B delivers 34kW of raw infrared power from a 40-litre tank.

Infrared vs Forced-Air: Choosing the Right Heater

Choose the DSH-IR30-B for large open or draughty spaces where radiant heat is the most effective solution, or where low operating noise is important.

Choose a forced-air model (DSH58, DSH68, DSH108) for more enclosed spaces where heating the air volume quickly is the priority.

Why Choose the Draper DSH-IR30-B?

At 124,000 BTU, the DSH-IR30-B sits at the top of the Draper portable heater range — and it earns that position. It combines the efficiency advantages of infrared radiant technology with the sheer output needed to heat truly large spaces, all from a heater that draws just 94W from the mains.

The automatic ignition, photocell safety system and overheating protection make it safe and practical for sustained use on professional sites. The 40-litre tank reduces downtime. And the radiant heat technology means every kilowatt of output is working as effectively as possible — not being lost to draughts or high ceilings before it reaches the people on the ground.

For large-scale, demanding heating applications, this is Draper's most capable portable heater.

Frequently Asked Questions

What is the runtime on a full tank? The DSH-IR30-B has a 40-litre tank and a maximum fuel consumption rate of 2.6L/hr. At full output this provides approximately 15 hours of continuous operation — well over a full working day on a single fill.

Does the DSH-IR30-B have a thermostat? The DSH-IR30-B does not feature a thermostatic control unit. If thermostatic temperature control is a priority, the smaller DSH-IR-B (17kW) includes this feature. The DSH-IR30-B is designed for maximum output applications where sustained full-power operation is required.

What fuel does the DSH-IR30-B use? The DSH-IR30-B runs on diesel, including red (agricultural/commercial) diesel. Unlike the DSH-IR-B, it is diesel-only — kerosene compatibility is not specified for this model.

What does the photocell safety device do? The photocell 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 safely — preventing unburned fuel from accumulating.

Is this heater suitable for indoor use? The DSH-IR30-B is suitable for well-ventilated spaces only. It must not be used in sealed or airtight rooms. Always ensure adequate natural ventilation when operating this heater.

How does infrared heating differ from a fan heater? Infrared heaters emit radiant heat that is absorbed directly by objects and people rather than heating the surrounding air. In large or draughty spaces, this is far more efficient — warm air heated by a fan heater rises and escapes, while radiant heat from an infrared heater reaches its target regardless of air movement.
