  • Best for: Garages, workshops, warehouses and agricultural buildings needing continuous high heat
  • Not ideal for: Small domestic rooms or occasional low-level heating requirements

High-output diesel/kerosene space heater with adjustable thermostat and automatic shut-off. Portable construction includes a pre-fitted UK 13A plug and a three-year warranty.


Rapid heat for large volumes - with 20kW (70,000 BTU/hr) output

A 20kW rated burner produces forced warm air capable of moving heat through open spaces efficiently, designed to cope with volumes of up to 400m³. The high BTU output shortens warm-up time compared with small electric or halogen heaters.

Faster warm-up in garages and workshops reduces downtime and keeps environments at a usable temperature for longer shifts.

Long run times with low fuel consumption - thanks to an efficient 1.9 litres/hour burn rate

Fuel consumption averages around 1.9 litres per hour, allowing continuous operation on a single fill for up to ten hours as stated by the manufacturer. The lower burn rate compared with small portable heaters means less frequent refuelling.

Extended operation between refills limits interruptions during a workday and helps control running costs for regular use.

Safe, straightforward control - with built-in thermostat, gauges and automatic shut-off

Easy-to-read gauges and an adjustable thermostat enable precise temperature control while automatic shut-off engages under fault conditions. A pre-fitted UK 13A plug provides simple electrical connection where mains are available.

Accurate temperature settings maintain comfort without guesswork and safety systems reduce the risk of overheating on busy sites.
