Our take on the Sealey Space Warmer Indirect Kerosene/Diesel Heater 68,000Btu/hr with 5M Ducting ABI600COMBO

The Sealey ABI600COMBO is an indirect-fired space heater rated at 20 kW (68,000 Btu/hr) that runs on kerosene or diesel. Unlike a direct-fired heater, it burns fuel in a stainless steel combustion chamber and pushes the exhaust out through the included 5 m duct, so the heat that reaches the room is clean, dry and fume-free. That makes it the right tool for occupied spaces and poorly ventilated rooms: marquees, halls, workshops and sites. It has a 38 L tank, 600 m³/hr air output, a thermostat, electronic flame control with a flame-out cut-off, a Danfoss pump and wheels with a handle for moving it. Against cheaper direct-fired heaters it costs more and needs the duct routed outside, but it is the safer choice wherever people are working.

Best forHeating marquees, halls and events with people presentWorkshops, warehouses and construction sitesRooms with limited ventilationCold-weather site work where fume-free heat is required
Pros
  • Indirect design sends fumes out through the duct, so the heated air is clean and dry
  • Runs on either kerosene or diesel
  • Thermostat holds a set temperature instead of running flat out
  • Flame-out device and electronic flame control cut the fuel if the flame dies
  • Stainless steel combustion chamber, Danfoss pump and fan cooling
  • Wheels and handle make a heavy unit movable on site
Cons
  • Bulkier and heavier than direct-fired heaters, and needs the duct routed outside
  • Indirect heaters lose some heat up the exhaust, so output at the room is lower than the rating suggests
  • Needs a power supply and a clear path for the 5 m duct
  • Fuel use is high at this output; the 38 L tank empties quickly on full heat
  • Other accessories shown are not included

About the Sealey Space Warmer Indirect Kerosene/Diesel Heater 68,000Btu/hr with 5M Ducting ABI600COMBO

This is an indirect-fired space heater that runs on kerosene or diesel. It delivers 20kW (68,000Btu/hr) of heat and moves 600m³/hr of air. Combustion by-products leave through a flue at the top of the heater, so the heated air is clean, dry and free of fumes.

It comes with 5m of flexible ducting to vent exhaust fumes safely. This lets the heater be used indoors and in poorly ventilated spaces. The 250mm wide glass fibre ducting is flame and heat retardant to 300°C and packs down for transport. The heater suits marquees, events, halls, workshops, warehouses and construction sites.

A thermostat measures the room temperature and switches the heater on and off to hold the set temperature, which saves fuel. Electronic flame control and a flame-out device cut the fuel supply if the flame goes out or the fuel runs out. The combustion chamber is stainless steel with fan cooling, and the heater has a built-in flame sensor and a Danfoss pump. Large wheels and a handle make it easy to move and position on site.

Questions and answers

What is the difference between this and a direct-fired heater?
A direct heater blows exhaust into the room along with the heat. This one burns fuel in a sealed combustion chamber and ducts the exhaust outside, so the air it delivers is clean and fume-free and it can be used where people are present.
Can it run on diesel as well as kerosene?
Yes. Sealey rates it for both kerosene and diesel. Kerosene burns cleaner and is the usual choice indoors; diesel works but can smell more and may need more servicing.
How much space will it heat?
Sealey rates it at 20 kW / 68,000 Btu/hr for marquees, halls, workshops and sites. Real coverage depends on insulation, outdoor temperature and how the duct is routed, so treat the rating as a guide rather than a room size.
What is included with the heater?
The heater and the 5 m flexible duct for exhausting fumes. Other accessories shown are sold separately.
Does it need ventilation in the room?
The exhaust goes outside through the duct, which is why it suits rooms with limited ventilation. The burner still needs combustion air, so do not seal the space completely.
How is the temperature controlled?
A thermostat lets you set the ambient temperature and the heater cycles to hold it. Electronic flame control and a flame-out device shut off the fuel if the flame goes out or the tank runs dry.
