Knight Division TacticalDoes KDT provide indirect-fired tent heaters?
Indirect-Fired Tent Heaters
Yes.
KDT provides indirect-fired tent heaters, diesel heaters that send clean, dry heat into tents and shelters through ducting while the exhaust stays outside, delivered, fueled and serviced on your incident.
Typical configuration
- Output
- About 150,000–1,000,000 BTU/hr; tent units commonly 150,000–400,000 BTU/hr
- Fuel
- Diesel or kerosene, roughly 1 gal/hr for every 120,000 BTU/hr of output
- Power
- 120 V, typically about 3–15 A for burner and blower
- Ducting
- Flexible duct, typically 12–20 in., one or more outlets
- Controls
- Remote thermostat, flame safety and high-limit shutoff
- Tank
- On-board tank good for roughly 8–24 hours; external tank hookup on many units
An indirect-fired heater burns diesel or kerosene inside a sealed combustion chamber and blows clean outside air across a heat exchanger into the tent. The combustion gases leave through a separate flue. That's the difference that matters: a direct-fired heater puts its exhaust and water vapor into the space it heats, which is acceptable for drying out an empty building and dangerous in a tent full of sleeping people.
Tent heaters sit outside the shelter and connect through flexible ducting, with a thermostat inside. They need a small 120 V supply for the burner and blower, and fuel from the on-board tank or a larger tank alongside. KDT sizes heaters to the tent volume and the overnight low, sets them up with ducts and thermostats, and keeps them fueled through the night.
Cold-weather spill response, high-elevation camps, winter storms and post-hurricane shelters all need heat. We place heaters clear of tent walls, check flues and burners on every round, and put carbon monoxide detectors in heated sleeping spaces.
Available as
- 150,000–200,000 BTU/hr heaters for single tents and trailers
- 300,000–400,000 BTU/hr heaters for large frame tents
- 500,000–1,000,000 BTU/hr trailer units for clearspans and warehouses
- Direct-fired heaters for unoccupied drying and thawing only
- Propane heaters
- Electric heaters for small spaces

Questions, answered.
Does KDT provide indirect-fired tent heaters?
Yes. We supply indirect-fired diesel heaters with ducting and thermostats, and we deliver, set up, fuel and service them for the length of the incident.
Why indirect-fired instead of direct-fired?
An indirect-fired heater vents its combustion gases outside and only sends clean, dry heat into the tent. Direct-fired heaters put exhaust and moisture into the space, so occupied tents get indirect-fired heat.
How big a heater does a tent need?
It depends on the tent size, insulation, wind and the overnight low. A large frame tent on a freezing night may need 300,000–400,000 BTU/hr or more. We size each tent and add margin for wind.
How much fuel does a tent heater burn?
Roughly 1 gallon of diesel per hour for every 120,000 BTU/hr of output, so a 400,000 BTU/hr unit on full fire burns about 3 to 3.5 gallons an hour. We keep them fueled on an overnight schedule.
